I have an old AF 1.8/50 on a D80 that works only at minimum aperture - f16 (manual mode). Otherwize it wouldn't shoot! It may be a problem with the lens, but I would suggest to bring one AF along to the shop and test it.

D80 is a nice and very user-frienly cam.

Same happened to me, but instead on a carpet, it was on a concrete floor. It was on a table tripod equipped with a pretty heavy 180 mm.

First I did notice anything, then I accused the new lens 18-200 of focussing incorrectly. After I upgraded to the D80, I took much sharper pictures. When enlarging the pictures taken with the D50, I noticed a difference in focus right-left. It is likely that the low-pass filter moved slightly. I would recommend you send your camera for a revision. One day you may have to discard a whole lots of nice pictures.

Sorry, thanks to Jon!

Thank to Joe for the confirmation. Voigtlander is a nice lens with outstanding optical and mechanical quality, equivalent to the Zeiss at half price. I have a manual focus (Sigma 105 macro), but I do not use autofocus for Macro, it never works. In addition, no manual metering is not a problem, Digital can afford test pictures at minimal cost...

I am going to order a Voigtlander APO-lanthar Macro 125/2.5. Will it work OK

on a D80 body in manual mode? Has anyone experienced/tested it?
