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.

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.)

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.

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.

Hope you can modify that.
