Does anyone have experience with this? I'm aware of the potential issues with an additional rear element to allow infinity focus; very curious to know how much damage it does to IQ.

Pasting link again because for some reason the formatting of the original message doesn't work unless I do:

I've never used one of these adapters, I stay away from adapters with glass elements because the quality of that glass is often in doubt. _________________ Gary

Thanks for clarifying about the link - I was well on my way to drawing unflattering conclusions about the site admins.
Yes, the glass quality is what concerns me. I have virtually a complete set of the best Konica primes, and had long ago nearly given up on the idea of being able to use them on a digital camera until a few days ago when I happened across a reference to the Sony Nex adapter. Now I'm thinking I may sell my Canon digital gear to make the shift, but want to investigate options first.
I used to have a Konica 2x extension that worked reasonably well, at least with longer lenses, but I'm sure they were much more careful with the design than an aftermarket extension manufacturer.
I probably won't do anything drastic until I hear definitively whether the rumored (or can we say anticipated?) new full-frame Nex will take the Konica adapter. If it does, well, there is a god after all. _________________ Konica AR: FT-1 Black, T3n, T3, 21/2.8, 24/2.8, 28/1.8 UC, 40/1.8, 50/1.7, 50/1.4, 55/3.5 Macro, 57/1.2, 85/1.8, 100/2.8, 135/3.2

The glass element is removable, they say it's necessary for infinity focus, though. I'm getting on of these for my 60D, I'll report back on how well it works. |

Thanks - that will be much appreciated.
Yes, the presence of the glass element is to allow infinity focus. Konica used a shorter lens-mount-to-film-plane distance than the other major makers, which is why direct mounting with infinity focus on other 35mm systems was impossible: the lens can't get close enough to the film without drastic action (i.e., grinding off ~3mm of the barrel).
Of course, a full-frame NEX would change everything. _________________ Konica AR: FT-1 Black, T3n, T3, 21/2.8, 24/2.8, 28/1.8 UC, 40/1.8, 50/1.7, 50/1.4, 55/3.5 Macro, 57/1.2, 85/1.8, 100/2.8, 135/3.2

Got the adapter in today. I only buy fotodiox adapters because I like their quality, and this one seems to be really well built as expected. My Hexanons all lock in secure, no shimmy or wiggle. My 60D won't be here for a few more days, as soon as I get the chance I will test it out and post back. I'm going to lock it on a tripod and shoot one shot with glass in and one without, will post full-res crops. Be interesting to see if the lens effects quality at all (I'm hoping it doesn't).
