zenitar M42 on minolta dynax 505 si

I bought a zenitar fisheye 16/2,8 M42 and the adapter ring for the minolta AF

system... i'm able to use that lens with my sony a100 but not with my minolta

dynax 505si...

what i don't understand is why everything seems to work if the 35mm film is not

inside the dynax camera body; once putted the film into the camera, the shot

button seems to be out of work...

anyone can help me?

thanks!

Have you tried puttin you camera into manual mode?

This was i would think you would not see the aperture setting in the viewfinder, you would have to use stop down metering, but you would still obviously get Through the lens metering as the camera would chose the appropriate shutter speed.

Have you done this process?

Hope i can give you some more help,

Richard

Okay, the film cameras all have a shutter-release lock that is by default employed when there is not a coupled lens on the camera. This is to protect your film and to keep you from accidentally exposing it. Since digital doesn't present the same opportunity to ruin an expendable resource like film the same is not true of the DSLR's. That being said, there is a chart somewhere on the pop photo website (I believe), that gives you the various button combinations that will over-ride the shutter-release lock for various Maxxum cameras. This is what I found doing a quick google for minolta shutter-lock:

Minolta/Konica Minolta "Shutter lock" or "lens check" feature:

Minolta's way of "saving" us from taking a picture with a faulty electronic lens attached, or from damaging the shutter or sensor can often be found in the owner's instruction manuals and service manuals for various Minolta electronic SLR cameras.

Minolta xi and si cameras, and most later models, have a shutter lock / lens check feature which prevents the shutter from being released if anything other than a functional AF lens is fitted -- slide copier, T-mount lens, telescope / microscope adapter, M42 lens, other adapter for other lenses, or of course any dysfunctional or incompatible electronic AF lens.

To over-ride this "safety" feature on demand, Minolta incorporated controls in many of their interchangeable lens AF SLR cameras. Note: Minolta/Konica Minolta APS/35m/Digital AF SLR camera models are variously named Alpha (Japan and China), Dynax (Asia, Europe, Africa), and Maxxum (the Americas).

Hope this solves your problem!

This feature is called "lens release lock". It disables releasing the camera when a non-electronic lens is mounted. To disable it, do the following:

<p>

Press and hold the self-timer drive mode button and spot/AE button while sliding the main switch to ON (OFF appears in LCD panel). Do the same to re-enable the feature (ON appears in LCD panel).

OK!

Also the sony a100 has a lens release lock by default, but it's possible to turn it off from the main menu of the camera...

I thought that the lens release lock worked independently from the prensence of a film, insted now i know it's not so...

Thanks a lot to all of you!

Bye!

I followed this information and I'm very happy with the results on my KM gear. Thank you very much.
