The Canon EF information in the metering column is incorrect, at least for the 10D which does meter correctly with an M42 Adapter and also works in Av (aperture priority) mode.
I suspect that if the 10D works in this mode then quite a few Canon DSLRs will also work in this way.

hi all,
Please keep sharing your personal experience in the comments.
i find it very rewarding when people like me who’re keen enough to read up all the comments. whether the author willing to change what he had posted or not that’s not important as he’s posting what he knows, and you’re commenting on what you know.

thanks all for the trouble!!

Besides, i would also like to contribute a lil.
I’ve had a Nikon D70/D70s
and it only allows M42 lenses to be used in Full Manual mode with no metering. But there seems to have focusing confirmation(without beep) when u look in the view finder, the focusin dot would flashes when u’re in focus.

and for Nikon user who happens to have lens with focal range over 300mm, i find that these long telephoto doesn’t need focusing element on the adapter and they’re still able to focus to infinity *please proves me wrong as i only have tried 2 telephoto, 1 is 100-300, another is mirror 500mm*

Thanks!

The Nikon Column is partly incorrect. Modells like die D200, D300 and D700 will provide metering.

Moreover, you should add information about the field of view crop (FOV) to your post. It is notable that only Canon, Nikon and Sony provide Cameras without FOV at the moment. As FOV changes the charecteristic of a lens completely, I dont share your recommendation for Pentax.

Hi,

The Sony column is incorrect: Sony DSLR cameras support metering even with a non-electric adapter. However, Sony DSLRs other than A100 and A700 do not support aperture priority auto-exposure (the A-mode) unless an electric adapter is used (but in M-mode the meter reading is still available). Also, focus confirmation works with an electric adapter (accuracy depends on how closely the focal length information transmitted by the adapter matches that of the lens being used; same as for anti-shake).

So, the metering-column should be “yes” and focus confirmation -column should be “no/yes*”… at least for Sony (of which I have extensive personal experience with and without electric adapters =). I believe these hold for Minolta DSLRs, but I have not verified this myself. (Meanwhile Minolta AF film cameras require various tricks to work at all with non-electric adapters, so this depends on the camera.)

Hi,

Some Nikon models does metering with M42 lens.
Models starting from D200 and upper level have metering with non-cpu lenses. Use non-CPU lenses in menu settings.

Hi,

I don’t see any problem with link you have posted, but if there’s something I didn’t notice I will explain it:

Old Pentax cameras had M42 screw mount, sometimes also called Pentax screw mount. Newer Pentax cameras have Pentax K-mount which is obviously bayonet.

Hi , please note that this link has misleading info, as K-mount has bayonet, not M42 screw.

Hope you can modify that.
