50 years of lens mount evolution (Part I of VI)


Nikon was very proud a few months ago when the 50th anniversary of the F mount was celebrated. Half a century! Pentax had to abandon its original mount and transition to a new bayonet in the early seventies, Minolta and Canon in the mid eighties.

But there is more to lens and body compatibility than the design of the bayonet.


Even if the current Nikon bodies and lenses still use the same bayonet design as the Nikon F of 1959, it’s practically impossible to pair an unmodified lens from 1959 to a recent body, and vice versa: the lens and the body of a modern SLR have to exchange information and commands, and non-upgraded lenses from 1959 simply don’t share enough information to be usable.


The transmission of information from the lens to the body – focal length, maximum and minimum aperture, pre-selected aperture, focusing distance, and of commands from the body to the lens – setting the focusing distance, setting the aperture value, closing the diaphragm, can be performed from many different ways – some of them passive (a hole in the metal), some of them mechanical (rods, cogs and springs), the most recent working exclusively through electrical contacts.


Diaphragm pre-selection


Cameras of the mid fifties were far less complex than the ones we now use. No internal meter, no auto exposure, no auto-focus.


But users of SLR cameras were facing an important issue: because the viewfinders of their cameras were dim and the focusing screen grainy, the only practical way to set the focus was to open the aperture to its maximum. Let’s say F:1.4. But if on a sunny day they needed to shoot at 1/125 sec at F:11, they had to set the aperture ring to F11 AFTER they were finished with the focus and – of course – BEFORE they took the picture. Not very fast, not very convenient.


At the end of the fifties, most Japanese camera manufacturers adopted automatic diaphragms with aperture pre-selection: the lens remained at full aperture – let’s say F:1.4 -independently from the aperture value selected by the user on the aperture ring, making focusing easy. Only when the user pressed the shutter release to take the picture would a lever or a rod mechanically close the diaphragm to the value pre-selected by the user.

Leica, Witness to a Century (book review)


“What camera took these pictures?”


That’s the question that photographers hate the most. Nobody ever asked Picasso what type of brush he was using to paint “Guernica”, and photographers believe they are the ones taking the pictures. For them, their camera is just a tool, that they use it to communicate their vision.


Well, it’s not completely true. Granted, the camera is a tool, and tools don’t create. But the camera’s characteristics, its size, its weight, its ability to withstand adverse environmental conditions, the number of manual steps needed to take a picture, the performance of the shutter, the aperture of the lens, all limit the ability of the photographer to take a usable picture of what he’s witnessing, or to convert his vision into an image. Every now and then, a breakthrough in the design of cameras gives photographers more opportunities to report what they see. Whenever a new generation of cameras hits the market, photographers start experimenting, and in the process, harvest a new crop of pictures, which sometimes, will change the way they show the world to the rest of us, and ultimately, change the way we all see the world.


Few cameras had an impact comparable to that of Leica cameras’ in the first half of the 20th century. The originality of Alessandro Pasi’s book – “Leica, Witness of a Century”, is that it’s an attempt to show how the Leica changed photography, and how photographers still use it today to make different pictures.


Leica - witness of a century (Alessandro Pasi)
Leica - witness of a century (Alessandro Pasi)


Alessandro Pasi’s book is organized is six chapters, each covering a different period, and showing in detail the most emblematic Leica camera of the era, as well as the pictures taken with it by the most prominent photographers of the time.


There will be no striking discovery for the well learned Leica aficionado. The cameras shown here have already been described in detail in many books, and at least half of the photographs assembled by Alessandro are well known “classics”.


But the author also included less known pictures taken by Italian photographers, as well as family snapshots taken by amateurs over the course of the century.


The texts are well written and informative, the layout is clear and the pictures are always given the priority.


This book is a very good illustration of the saying about the whole being greater than the sum of its parts.


It’s a pleasant voyage through one century of photography, an homage to the ingenuity of the creators of the Leica, and the proof that sometimes, “what camera took these pictures?” is not as stupid a question as it sounds.


Leica, Witness to a Century, is available in brick and mortar book stores, and also at Amazon . 159 pages. $35.00



For the 75th anniversary of the Leica, in 1989, the Leica Camera Group published “75 Years of Leica Photography”, which showcases more than 300 pictures taken with Leica cameras, from the test shots of Oscar Barnak in 1914 to the fall of Berlin wall in 1989. A very interesting follow up if you liked Alessandro’s book. It can still be found – used – for a bit less than $100.00

Leica M9 – a few thoughts


Leica launched the M9 today – the full-frame digital version of M rangefinder camera series. DPreview published its hands-on review already.


With its 24x36mm 18 Mpixels sensor, the M9 will be positioned in the same price category as the Nikon D3X and the Canon 1DS Mk III, both proposed above $6,500.


As far as I know, no price has been published for the North American market yet, but the list price published for the UK and for Continental Europe leads me to believe that the M9 will sell somewhere between US$6,750 and US$7,500 on this side of the Atlantic.


That’s a lot of money. I’m not a Leica collector, or a pro photographer always looking for ways to produce different images. I’m just an amateur, taking a few thousands of pictures per year, most of them in situations where a single lens reflex is far more efficient than a rangefinder camera like the M9. And I could not help doing some math:

  • a used Leica M7 can be found for $2,500. The cost difference with a brand new M9 will be $4,250 at least
  • $4,250 can buy enough B&W film to take 10,928 pictures and have them processed, scanned medium res and copied on CDs at Costco
  • $4,250 can buy enough B&W film to take 3,400 pictures and have them developed, scanned in high res and copied on CDs by a pro photo lab.
  • $4,250 can also buy a plane ticket to the destination of my dreams, where I would spend two months taking pictures


I would not even use a M7. Leicas are about street photography, the smaller, the better. An old Leica CL (or even better, its Minolta sibling, the CLE) is not as prestigious as an M7, but it does the job. For $400. How many more pictures?

The Olympus OM system and a camera to rediscover: the OM-2s (Intro)


Take any line of manual focus 35mm reflex camera from the eighties and mid-nineties, Leica R included. Comparable models will be worth less, on the second hand market, than an Olympus OM-4T, not to mention the OM-3 and its ultra-rare and ultra-expensive offspring, the OM-3T. Why, in spite of their very serious limitations, are the single digit OM cameras so sought after? In this test of the OM-2s, the little brother of the OM-4, we’ll try and find out why.


The OM system


Olympus OM-1n next to a 35mm film cartridge. The competition needed almost 10 years to introduce more compact SLRs, but they were designed for beginners. In the enthousiast-amateur and pro categories, the OM family remains unchallenged to this day.


Launched in the early 70s, the Olympus OM-1 and its system of lenses and accessories were incredibly compact, very well designed, and at the same time solid enough to please the pros and the very serious amateurs. The competition (Nikon in particular) needed years to develop models approaching the size of the OM-1, which sold by the millions.


The OM-2, introduced in 1974 with the same ergonomics and a similar external appearance, was the automatic exposure version of the OM-1. It pioneered the use of direct exposure metering in the film chamber, and was the first camera with Through The Lens Flash metering. The competitors followed Olympus’ example, and almost every SRL cameras introduced after 1985 measures the exposure in the film chamber and offers TTL flash metering.


The OM-2s, OM-3 and OM-4 which followed in the eighties were relatively minor updates of the previous models. They shared a new body and had much more elaborate metering options, but they retained the relatively slow shutter of the OM-1 and OM-2. Their viewfinders were not as great as the ones of the OM-1 and OM-2, and the first models had some reliability issues. The OM-3T and OM-4T (with titanium top and bottom plates and more reliable electronics) raised the level of quality of the OM line, and soldiered on until Olympus finally stopped the production of film cameras, in 2002.

Buying photo equipment on eBay


I bought most of my cameras and lenses on ebay.com, sometimes through auctions, sometimes at  “buy it now” prices. I never had a bad experience so far.


If you buy on eBay, you will face three types of sellers:

  • on-line stores specialized in photographic equipment, new or second hand.


That’s the low risk option. Some stores limit their inventory to a few brands, and only carry high quality, very nice to pristine cameras. Others are less restrictive, and also have cameras which have lived a more difficult life. If your intention is to really use the camera you’re purchasing, buying a comestically challenged camera may be a good option, as long as it’s in good mechanical condition. Specialized stores are supposed to know what they sell, and will not plead ignorance if the product does not work or is not completely similar to the published description. They will arrange for a free return, and a refund.


A word of caution, though: the products are evaluated before being listed, and the obvious lemons don’t pass, but the tests are not always as thorough as one would wish: a lens may have looked OK when tested on a particular type of body, but will fail to operate on another one, which is in theory 100% compatible but is interacting with the lens differently. Always test the equipment you purchased as soon as you receive it, and contact the seller if there is any issue. Reputable stores will listen to you, and they have a good return policy.


Over the years, I bought cameras or lenses from Adorwin (the eBay store of Adorama), Betteroffblu, Cameta and Shutterblade and could appreciate their professionalism.

  • Stores not specialized in photography


That’s the riskiest option, in my opinion. The store could be anything, from a pawn shop to an antique dealer, the worst being a dollar store or a shady repair shops buying broken electronic equipment in bulk and making one sellable camera out of 3 broken ones. Even if they know a few things about the products they’re selling, they will generally plead ignorance, and will offer little or no support if there is an issue with the equipment. I never had a really bad experience on eBay, but it’s with this type of seller that I came the closest to being seriously disapointed. Buyer beware.

  • Low volume and non professional sellers


Low volume sellers belong to multiple sub categories. You will see items sold by a person who pretends he got the equipment he’s selling from a friend but that he knows nothing about it, and  you will find the passionate amateur photographer who bought his equipment new 20 years ago, used it day in day out and took great care of it; he will take pride in providing a honest and accurate description of his equipment, and that’s the person you want to be buying from.


Because of the way the auctions work, the prices tend to be highly variable and very unpredictable. Professional sellers tend to protect themselves with a “buy-it-now” price, and if the item does not sell this time, they just list it again. Non professional sellers tend to use the auction system more than professionals. With the number of people watching eBay listings every day, it’s difficult to find a real bargain, but some sellers (lazy or inexperienced) still publish unappealing listings (blurry pictures, ambiguous descriptions) that a trained bargain hunter will be able to interpret to his advantage: I bought my Nikon F3 this way, at 30% of what the action would have reached if the listing had been professionally layed out.


As always, do your homework and try and understand the market first (ads in magazines, completed items list on eBay). Set a limit for the price of the equipment you want to buy second hand. In any case, read the ads very carefully, ask questions, and only place a bid if you feel confident enough.


Other reputable sources

  • keh.com


    I never had the opportunity to buy second hand equipment from keh, but good friends did. keh has the reputation of being very conservative in the way they describe the equipment they’re selling (if they say it’s in good condition, then it’s very very good). They only sell over the phone or on the Internet – no walk-ins.

  • bhphotovideo.com


    B&H is a big photo video mail to order company, with a huge brick and mortar store in New York. I bought new equipment from them on multiple occasions. A very pleasant experience. I never had the opportunity to buy second hand equipment from them, though.

Why are manual exposure cameras worth more than automatics ? (Intro)


The facts


Let’s take three lines of manual focus cameras which still have a very active second hand market today: the Leica R series, the Nikons FM & FE and their derivatives, and the Olympus OM-1 & OM-2 and their “single digit” descendants. Each line contains automatic exposure cameras (Leica R4, R5, R7; Nikon FE, FE2, FA; Olympus OM-2, OM2s, OM4, OM4t), and manual exposure cameras (Leica R6, R6.2; Nikon FM and FM2; Olympus OM-1 and OM-3).


For a given generation of camera, manual exposure models are almost always worth more than their automatic exposure siblings.

Leica R6.2: $ 999 R7: $ 550
Nikon FM: $ 190 FE: $ 170
Nikon FM2: $ 245 FE2: $ 199
Olympus OM-1: $ 150 OM-2: $ 190
Olympus OM-3: much more than $500 * OM-4: $ 235
Olympus OM-3T: much more than $1,000 * OM-4T or TI: $ 450

Nikon FM: compact and rock solid, a good risk-all backup camera for Nikon users


In the mid seventies, a new generation of SLRs hit the market. They were following the example set by the Olympus OM-1 and were much more compact than their predecessors. They also used less mechanical components and more electronics.


The FM was Nikon’s response to the OM-1, and to similarly compact cameras from their main competitors. The FM outlived them all. The FM and its derivatives, the FM2 and the FM3a,  were sold for more than 30 years, and when the production of the FM3a was finally stopped, they were still in such demand that for a while used FM3a’s were selling for more than when their price when new.


Compact, reasonably light and rock solid, the FMs were often used as backup cameras by professional photographers until they stopped using film a few years ago.

 

Nikon FM
Nikon FM – it accepts pre-AI lenses, AI, AIS, AF and AF-D lenses.

 The FM is a mechanical, manual focus, semi-auto camera. It leaves you total control over your images, and does not change the aperture/speed combination you selected on its own. No need to memorize the settings in backlit pictures. But total control comes at a cost: speed of operations in a rapidly changing environment. It’s a nice camera for landscapes, travel, street photography, but more recent autofocus cameras will deliver better results for sports and action photography.

 
The flash control system is also old school – the camera exchanges very little information with the flash unit, and the photographer has to set the shutter speed and the aperture by himself, using guide number tables: there are obviously better cameras to shoot indoors.


 

The FM as a photographic tool


By modern standards, the FM is a bit of a disappointment. On the one hand, it feels very well built and solid, and it can be carried around everywhere because of its (relative) small size. The Olympus OM1 or the Pentax M series are still smaller, but don’t feel as robust.  Like the other semi automatic cameras with mechanical shutters, the FM also works without batteries. The light meter does not use a galvanometer (no needle) but a series of bright red LEDs are the right of the viewfinder screen: there are very few parts that can break on a FM.


On the minus side, the mechanical commands are firm, and the advance film lever doubles as a shutter release lock: you can only use the light meter and press the shutter release if the advance film lever is pulled out of the body (by an angle of approximately 45°). It’s not very practical, and slows down the operations. I missed more than a few snapshots because the lever was pushed flush with the camera body, in the off position. I guess you can get used to it, but it’s not ideal. (the Nikon F3 does not have this issue; the film advance lever does just that).

Nikon FM / Olympus OM1n
Nikon FM / Olympus OM1n – the smaller prism cover make the OM-1 look smaller.


The Olympus OM1 was the forerunner of a new generation of very compact but still very capable SLRs. Coming a few years later, the FM is not as compact as the OM1, but not that much larger. It’s heavier, though. Its electronics (the light meter, the rest of the camera is mechanical) aged very well, the batteries it needs are still easy to find, its mechanical components are solid and it’s compatible with any Nikkor lens built between the early sixties and the last few years.

 

Nikon FM - Shutter
Nikon FM – Metallic shutter. Clearly a camera from the seventies.


The FM has a mechanical metallic shutter. Its fastest speed is 1/1000sec, with a  maximum flash synchronization speed of 1/125 sec. The different versions of the FM2 and the FM3a have much faster shutters, built in aluminum or titanium, with a maximum speed of 1/4000s and a flash synchronization. speed of 1/200 (early models) or 1/250.

Nikon FM
Nikon FM –  depth of field preview lever and self-timer at the right of the lens.


The FM holds a special place in the Nikon product range: it’s one of the few Nikon cameras (the only other compact SLR to share this characteristics is the FE) which is compatible with the pre-AI lenses as well as the modern AI, AIS and AF lenses. The other members of the family – FM2, FE2, FA, F3A – are only compatible with the AI, AIS and AF lenses; trying to mount an older pre-AI lens can damage the camera.

That’s the reason why the FM is sometimes referred as the Rosetta Stone of Nikon cameras

 

Summary


The Nikon FM is a simple, compact, rock solid and reliable camera, with a decent viewfinder and an accurate light meter. It’s not very fast to operate and not always pleasant to use because of firm commands and of the protruding film advance lever, but it can take advantage of a huge variety of lenses, built by Nikon over a period of almost 50 years. The FM2/FE2 are a bit smoother, the automatic FE and FE2 are also faster to operate, but the F3 beats them all, with its very soft commands, its good ergonomics and its large viewfinder.


The last FMs were produced in the early eighties, and good ones are still easy to find. They command lower prices than the much more sought after FM2’s and FM3a’s. A very nice one from a reputable seller will not cost you more than $150, and not so nice ones can be bought for less than $70 on eBay.

Nikon Pronea S

Nikon Pronea

Originally published in August 2009


Launched in 1998,  the Pronea S is Nikon’s second and last APS SLR. Nikon rapidly lost interest in the APS format, and refocused its R&D (and sales) efforts on the more promising Coolpix digital cameras. With its smaller image format and lenses, the Pronea can be considered a remote ancestor of the vastly more successful Nikon D40.

Nikon Pronea S (flash deployed)
Nikon Pronea S (with the built-in flash deployed and a Nikkor AF 24mm lens)


Apart from the fact it’s using APS film instead of more conventional 135 (24x36mm) film, there is nothing really remarkable about the Pronea S. Its characteristics are aligned on the other mid-level amateur cameras of its time.


It benefits from the advantages brought by the APS format (smaller size than 24×36 cameras, choice of three aspect ratios for the prints) but it also suffers from all the limitations that ultimately caused the demise of the APS format.


In a typical Nikon fashion, the Pronea S preserves some form of compatibility with the large family of Nikkor F lenses: in fact, modern AF and AF-S lenses work perfectly on a Pronea. However the IX-Nikkor lenses, designed specifically for the Pronea and its smaller APS  format are absolutely incompatible with the rest of the Nikon bodies: the back of the IX lenses protrudes so far in the reflex  chamber that it would be on the trajectory of the reflex mirror of a 24×36 SLR.

Both use the F mount, but an IX lens can only be mounted on a Pronea body

The back of the IX lens protrudes much more in the reflex chamber than the back of a Nikkor AF or AF-s lens

The resale value of the Nikon Pronea S is very limited. Mint (if not new) cameras and lenses can still be found, and they generally sell for a few dozens of dollars. They can be collected as curiosities, but their usage value is limited: Kodak and Fuji may cease manufacturing APS film rapidly, and the IX-Nikkor lenses are absolutely incompatible with any “normal” Nikon body.

Olympus OM1n / Nikon Pronea S (Side)
  • APS SLR cameras are smaller than a comparable 24×36 autofocus SLR with a built-in flash, but the Pronea S is larger than an older SLR such as the Olympus OM-1
  • The choice of films was already very limited when the format was supposed to be the next big thing: practically, color print film from Kodak and Fuji in 100, 200 and 400 ISO declinations was the only thing you could get. Now that the format is near extinct, only 200 ISO film is available.
  • Color slide and black and white film were never widely available, if available at all.
  • Compared to a 24×36 image, an APS image is 56% smaller. APS requires higher enlargement ratios, which makes film grain more visible.
  • The film loading mechanism of APS cameras is fragile. The film can stay trapped in the camera if one of the little plastic parts holding the cartridge in place breaks.

Paris – Garden of the Pont Neuf


Located at the very center of Paris, and linking the right and left banks of the Seine with the western end of the “Ile de la Cite”, the Pont Neuf (New Bridge) is the oldest bridge of Paris. It was built at the end of the XVIth century, under the reign of Henri IV whose equestrian statue dominates the area. A public garden lies below the bridge. It’s one of the most beautiful places in Paris. A (relatively) quiet place in a big city.
