Milan_S Posted May 29, 2018 Share #1 Posted May 29, 2018 Advertisement (gone after registration) Anyone else noticed that by using the Contax 645 to Leica S adapter on the S007 in liveview mode the autofocus doesn't work with the Contax 645 lenses?

Advertisement Posted May 29, 2018 Posted May 29, 2018 Hi Milan_S, Take a look here Leica S007 w/ Contax 645 adapter liveview. I'm sure you'll find what you were looking for!
mgrayson3 Posted May 29, 2018 Share #2 Posted May 29, 2018 Yep. I noticed that. OTOH, focus peaking makes the 120 a lot more useable. The 210 never AF'd well on my 006. I don't have one anymore, but with the 007 it would work. Only problem is, without IS, magnified LV on a 210mm lens would require a tripod. Link to post Share on other sites More sharing options...
Irakly Shanidze Posted May 30, 2018 Share #3 Posted May 30, 2018 210 autofocuses just fine on my 006 1 Link to post Share on other sites More sharing options...
mgrayson3 Posted May 30, 2018 Share #4 Posted May 30, 2018 (edited) My problem with the 210 was only at infinity. I recently got a 180 S and it also is a bit random at nailing infinity focus. Frankly, I would go for the SL+90-280 if I really wanted to work at the telephoto end. The 006 is brilliant with anything from the 120 to the 24.

Photon42 Posted May 30, 2018 Share #5 Posted May 30, 2018 Is that a contrast vs phase detection issue? And possibly the reason why the Contax adapter and lenses aren't supported for the (T)L mount? Link to post Share on other sites More sharing options...

Makes sense, but it's still strange since the only thing the lens has to do is focus forward/backward and then fine tune... just like with the normal autofocus chip.

I suppose it depends on what information is sent to the lens. Does the camera tell the lens "rotate 14.27 degrees" or does it tell the lens "phase difference -1.049" and let the lens take it from there? I could see Leica implementing the conversion calculation for its own lenses but not doing the same for adapted lenses.

Milan_S Posted May 31, 2018 Author Share #8 Posted May 31, 2018 Thank you all for the input. It's indeed a strange issue, I guess at the time Leica released the adapter the future option of liveview wasn't taken into consideration. Link to post Share on other sites More sharing options...

It's even more likely that Contax didn't anticipate liveview when they designed their 645 system in the 1990s. Link to post Share on other sites More sharing options...
