Voigtlander Bessaflex TM -- new "Pentax Screw Mount" SLR
$329 Silver or Black ORDER HERE
December 2003: Ok folks, some things are stranger than fiction. Mr. Kobayashi likes his Topcon Super D of 1963 enough to style the new silver Bessaflex after it, even producing a Topcon style 58/1.4 complete with the Topcon engraving. Mr. Kobayashi received the blessings of Tokyo Optical, which is still in business manufacturing medical equipment.
The new 58/1.4 Topcor is a new optical design and is styled after the classic 58/1.4 Topcor, even down to the Topcor's bayonet on lens hood. These are limited edition lenses, with 800 each announced to be produced in Pentax 42mm screw mount and Nikon AI mount. The lens barrel is out of place in today's plastic lens world, with real classic style chrome, looking just like it came off Topcon's production line in the 1960's. The lens barrel is beautifully made, and rather amazing in the "find any way to make it cheaper" manufacturing times. Side by side the new Topcor is a bit smaller than the original, so the hoods will not interchange. Specs: 7 elements in 6 groups, multi-coated, f/1.4 to f/16, 9 aperture leaves, 58mm filter size, close focus to .45 meter or 1:5.8, weight 305 grams (Nikon).
The Voigtlander Bessaflex TM arrived at CameraQuest 7/15/2003. The Bessaflex is a surprise as it revives the old "Pentax 42mm screw mount." It is the first Japanese 42mm screw mount SLR made in decades. For the fourth time in four years, Cosina's CEO Mr. Kobayashi re-introduces an "obsolete" lens mount for the benefit of forgotten camera fans.
Compact size, comparable to the Nikon FM/FE, conventional mechanical 35mm SLR layout, metal top plate, bottom plate, front plate, back door on a metal die cast body.
VERY VERY Bright finder
showing about 95% of film coverage, split image rangefinder focusing screen
surrounded by a circular microprism. The super bright finder is a strong
point for buying the new Bessaflex. Side by side, the Bessaflex finder
is noticeably brighter than the Fujica ST801 -- itself one of the brightest
finders of all classic 42mm screw mount cameras. Even if you wear
glasses, all four corners of the screen are easily seen -- a highpoint finder.
I doubt if there is a 42mm screw mount SLR with a brighter finder.
Silicon TTL metering, film speeds 25 to 1600 in 1/3rd stops, meter powered by two S76 batteries in bottom battery compartment, EV range 1 to 19 at ISO 100. The centerweighted meter cell reads off the pentaprism.
3 LEDs on left side of finder (outside the field of view) indicate exposure. The middle LED is a round green dot, with red plus or minus LED's above the green LED. Adjust the f/stop or shutter speed to light up the green LED.
Stop Down Metering: The meter
switch is on the left front of the mirror box, ideally placed to be operated by
your left thumb as you hold and focus the camera. Pushing the
button UP turns on the meter (shutter advanced or not), as well as stopping
down the lens to shooting aperture. The meter turns off when you
release the shutter release. Personally I found the push UP meter
switch very comfortable and easy to use. I was not
bothered nearly as much by the stop down metering as I expected to be.
Take note the meter switch stops down only AUTO diaphragm lenses. If the
lens is one of the older pre-set lenses or manual lenses, the meter will turn
on but you have to operate the aperture manually yourself.
Mechanical Copal Shutter: speeds 1 to 1/2000th plus B, flash sync 125th and slower. If the battery dies you only lose the meter, not the shutter. Comparatively few classic 42mm screw mount SLRs have a top speed of 1/2000, or a flash sync speed of 1/125.
Large shutter speed dial can be turned while camera is at eye level, rotating a full 360 degrees
Shutter Noise: The shutter sounds about average to my ears. Side by side it sounds different from the Nikon FM or Fujica ST 801 -- but still all about the same sound levels overall.
Black paint finish only, of a much finer "splatter" finish than the Bessa R2. It has a sheen to it, which may be a sealer. I like the newer Bessaflex finish better.
PC connection is at left end of camera, no built in hot shoe. The add on accessory shoe becomes a hot shoe with the PC connection. The plastic accessory shoe slides on and off over the grooved eyepiece.
No built in accessory shoe. Add the optional accessory shoe IF you wish to use a shoe mounted flash.
Short Ratcheted film advance of about 120 degrees, nice smooth advance action
Self timer doubles as mirror lock up, as the mirror goes up when self timer released ala Nikon FM
Standard threaded mechanical cable release, will take the Abrahamsson MiniSoftRelease
The Bessaflex takes the standard Bessa Rangefinder trigger winder and grips
Back door film window -- unusual in 42mm mount SLRs
The back opens by pulling the rewind knob upward. The film speed setting rotates around the rewind knob.
Lens Compatibility: Not all 42mm screw mount cameras and lenses are compatible with each other, primarily due to metering lugs on some lenses which interfere with lens mounting on some 42mm screw mount bodies. For instance, the excellent multicoated Fujinon screw mount lenses will not mount on some 42mm bodies unless the metering lug is ground off. I was happy to find that both the screw mount Fujinon and the Pentax Super-Multi-Coated Takumars mount and function perfectly on the Bessaflex TM. Due to the thick body depth, 42mm Screw mount lenses are blessed with are more lens adapters available for them to mount on other mount SLRs than any other SLR lens. Many classic adapters are listed here. Many modern adapters are listed here.
Stop Down Metering? What's that? Before many camera makers linked their lenses to the meters in the camera body, "Stop down metering" was standard for many SLR makers ( most notably for Pentax Spotmatic screw mount bodies.) This means the lens was stopped down to the shooting aperture to meter the light coming thru the lens at that aperture. Unfortunately as the f/stop gets smaller the finder gets darker -- impeding both focusing and viewing. "Open Aperture Metering" makes the meter calculations with the lens wide open for easier viewing and focusing by using mechanical or electronic meter linkage between the camera and lens. Thousands of different makes of 42mm screw mount lenses were made over the years. Comparatively few 42mm screw mount lenses used some type of open aperture metering. The only way to make the Bessaflex TM meter compatible with ALL 42mm lenses is to use stop down metering.
The same Bessa Trigger Winder for the Bessa R2, R2S, R2C, and Bessa T also fits the Bessaflex. Mounted is the superb and hard to find Pentax Super-Multi-Coated Takumar 85/1.8.
The same Bessa Grips which fit the Bessa R2, R2S, R2C, T and L also fit the Bessaflex. The side grip shown here also protects the bottom of the camera -- besides providing a better grip.
How does the Bessaflex compare to classic 42mm screw mount SLRs? Feature for feature, I think the super bright finder, optional bottom trigger winder, and back door film window are probably unique -- and possibly the mirror up self timer as well. Others features like a top speed of 1/2000th, flash sync of 1/125th, Silicon meter cell, and LEDs in the finder are unusual in screw mount SLRs, but not unheard of. While the classic Pentax Spotmatics have a better fit and finish, some shooters may find the overall balance of features in the Bessaflex a better shooting combination. If you are looking to find a good shooting SLR for your closet full of 42mm screw mount lenses, the Bessaflex merits serious consideration.
The Bessaflex can mount literally thousands of 42mm screw mount lenses. Some are quite unusual. Shown mounted on the left is the Spiratone 135/1.8. On the right is the Fujinon 16/2.8 full frame fisheye.
The Bessaflex compared in size to earlier 42mm screw mount SLRs: the Fujica 801 of 1972 and the original Asahi Pentax of 1957. The Pentax was the first Japanese made 42mm screw mount SLR. The Fujica 801 was the first 35mm SLR with a LED finder readout.
Trivia: the 42mm screw SLR lens mount was first introduced on the East German Zeiss Contax SLR of 1949, the first production 35mm SLR with a built in eye level pentaprism. Some believe its production came about a decade later than originally planned, interrupted by WWII. The lens mount was popularized by the Asahi Pentax, which started production in 1957. "Pentax" was originally a camera model in the Asahi lineup before it became the name of the company. Even the "Pentax" name was originally a Zeiss Ikon VEB trademark until bought by Asahi. It was originally derived from "PENTaprism" and "contAX."
The Hmm Dept: I wonder if the TM for Thread Mount might imply Mr. Kobayashi has plans for other classic lens mounts for the Bessaflex. Time will tell. Hmm.
