This is a comparaison of the two adapters I now have, and their focusing behaviour.
If you're looking for an adapter with a tripod mount to use in combination with heavier glass, forget about it ! The mounting plate is just too small to offer sufficient support. With my Nikkor 180/2.8 ED, it's very unstable !
I have not seen any maenta shift yet. But I rarely used the adapter with short lenses because of the infinity focus problem. Will check maybe later today !
"Hi, Kelvin,
I received the replacement adapter earlier this week and am in a process of further testing it "side by side" with my G1 and my Nikkor lenses.
So far, this is a comparaison between the two of them
180/2.8 ED @ 2.8
1st : infinity met
2nd : infinity met
105/2.8 @ 2.8
1st : infinity not met
2nd : infinity only nearly not met
85/1.4 @ 2.8
1st : infinity not met be a long shot
2nd : infinity only nearly not met
50/1.4 @ 2.8
1st : infinity not met be a very long shot
2nd : infinity not met, focuses up to 8m
35/2.0 @ 2.8
1st : infinity not met be a very long shot
2nd : infinity not met, focuses up to 7-8m
24/2.0 @ 2.8
1st : infinity not met be a very long shot
2nd : infinity not met, focuses up to 2-3m
All tests conducted @ 2.8 and with the shiftlock unlocked as you suggested in previous mails.
I would like to mention that the replacement adapter feels a lot "stiffer" in its manipulation, but that the tripod collar fixation has some game.
The 2nd adapter is a tad (< 1mm) lower than the 1st, but stiller ca 1.5mm higher than the cheap chinese one that (as already mentioned) focuses all lenses to infinity !
Is there a way to fix this ?
All in all, the second is definitely better in focusing, but, when focusing a 24mm lens no closer than 2-3 meter, should not be qualified as "focusing to infinity garanteed"
Looking forward to your comments !
C U,
Rafael"
