Exa and Exakta Screw mount Cameras

The following comments are courtesy of Bart Peeren :
(1) The exa's mirror acts as the first, opening, part of the shutter. The second, closing part is a metal 1/4 cylinder. This whole assembly is returned to its starting position when transporting the film. So, no instant return mirror!
(2) the m42 Exa's have only been made in very small quantities, the standard being the Exakta Bayonet with external auto diaphragm.

Exa Ia, 1973-??

It appears that some Exa Ia were made with M42 mount starting from 1973.

Exa Ib, 1977-??

Waist level view-finder, interchangeable finders, detachable back
Shutter: 1/30, 1/60, 1/125, 1/175, B
Flash: X-synch at 1/60
Metering: none

Automatic diaphragm
No instant return mirror

Exa Ic, 1985-1992(?)

(in USA Exa Ic is a different camera)

Same as Ib, but all black with greater use of plastic

The information about the following exakta cameras were provided by Gary Turner.

Exakta TL 500 , 1976?-??

(informaton by courtesy ofCeri Evans) Fixed pentaprism
Shutter: 1-1/500, B
Flash: X-synch at 1/60
Metering: TTL (stoped-down, CDS cell)
Automatic diaphragm
Instant return mirror
I've used it - though not intensively - and have had no problems. It's well built, solid, and finish is very good.

Exakta TL 1000 , 1976?-??

Similar to TL 500, but has 1/1000 top shutter spead

Exakta FE 2000 , 1977?-??

Similar to TL 100, but has atomatic aperture-priority control

(Exakta TL500,TL1000, FE2000 were made by Petri and are similar to Petri FT)

From Jacob:
The exa 1a was produced as a "little sister" model to the more expensive exas (with cloth shutter). It hat the exa/exakta bayonet mount. Due to the very simple shutter mechanism (which is, by the way, very smooth -- no vibrations, hold the 1/30 free-hand with f 50 mm or more), shutter speed is limited to around 1/150 s (varies within models). The 1b was a modification towards the more commonly available m42 lenses -- somehow a step back, but then was highly appeciated by customers; m42 lenses were cheaper and still are. The 1c was another modification -- more plastic parts, black outline, produced in a different factory -- but otherwise identical to the 1b. The camera back is not "interchangeable" but just goes off in order to load a film. Very crude, but just works. A perfect camera for indoor shots without flash -- iso 400 print film, 1/30, any m42 wide-angle 2.8 (I use a Tamron 2.4/24 which is tremendously sharp) will give fine results even in low pub lighting. Once you have experience in using the non-prism top-view finder (pic is sharp when you see more details than before), you'll love it. It is good work, although minimalism in technical things. Wind, point, focus, trigger -- and here you are. No more need for batteries or manuals. Due to the lack of high shutter speeds, this camera is not intended for use with tele optics. But it is an SLR. WYSIWYG. Outdoors, use a good light meter. Not a "one cam does all" model, but still great. Very reliable, probably survives a plane crash.
