often see a lot of lenses for sale with this metal tab on the side (the silver bit with two screws) the question is will it fit and possibly even work on a d7000 or d300 ,not entirely sure what the lens mount is designated as so cant look it up on my chart

Hi Jeff, you don't mention what the lens is. I think it may be a 28mm f2.8 but the numbers are very out of focus. The rabbits ears are for the very early aperture link to the auto exposure. You can ignore the rabbit's ears, unless they foul on the body in which case unscrew them, but don't throw them away. This lens is almost certainly an AI or AIS because of the ridge which stops just behind the f16 mark about two thirds of the way from f11 to f16 which would be correct for an f2.8 lens. I notice it has a mark for focus correction for IR (infra red), not sure if it's a good performer though, I would have to look it up. It's MF (manual focus) Regarding fitment, I don't think it will be much use on the D7000 because it won't meter with that lens I don't think. The D300 on the other hand has a list of lenses which you can select from in the menu, select 28mm, OK, then select the aperture, in this case 2.8, OK that then it should meter and record the lens details on the EXIF of each image made with that lens. It was part of the f2.8 non zoom lens program that Nikon produced over many years. MAY even still be available. Not very popular because of the MF and not being zoom.

Jeff, What is the closest focus it will make?

Black, re: a lot of lenses for sale. To me, it looks like any run-of-the-mill third party lens from ca 1977-1990 before AF came into fashion. There is a reason for the moderate price for lenses like this: There are many to go around and few people want them. Functionally it is equal to the Ai and Ai-s lenses from Nikon. Q: do you want to own and use a lens like this? I do not, I own more and better original Nikon lenses of the era. If one were given a lens like this, it might be nice to play aroud with on a rainy day, but little more. On current-day camera's (like your D300, but not the budget ones) Nikon includes an Ai-coupling ring and tab on the camera body. The so called rabbit ears (you describe as the silver bit) is designed for coupling with pre-1977 cameras. Regards, Gilbert

I'd have to agree with Gilbert. The lens is a non-Nikon Ai mount with meter coupling prong. This dates it to approx 1980. It is a 28mm f2.8 which since it is a cheaper lens from the 1980 period probably has horrible chromatic aberration so it has low value but maybe higher interest value.

If it were a genuine Nikon lens it would have been a very good one, esp if it had the 200mm close focus, because they are CFC. Equivalent to a 42mm on DX that could be a very handy length. It seems it isn't a Nikon lens so I agree it's value is very low, although occasionally these lenses can throw up surprises. A 28 f2.8 is on my list of wanted lenses but what I really want is a 20mm f3.5. Not interested in fancy zooms, I prefer the older non zooms. I have an 18-105 but I only use it for snapshots, it's way too slow.

Robert. I know I had a Nikon 20mm 2.8 and can't remember getting rid of it. I'll have a hunt if you are interested. Found the 24mm 2.8 so must be getting warm!

Oooo! Maybe the gods are smiling after all? It's the CFC (Close Focus Corrected) which focuses down to 200mm Bob, my LFCS has the other one which only goes down to 300mm. Thanks Bob. I want it for my PB4 Bellows to use for negative copying. The 55 Micro is OK but it's a bit long, it is hard to get full frame without a lot of fiddling, and the DoF is a bit more forgiving with the 28mm.

...focus down to 200mm with CFC... I reckon you're talking about this (Ai-S 28/2.8), Robert? It's my most often used lens indeed, sharp, easy to focus and very well built. A word of warning though: as this is a CFC lens, sample variation can be a problem. In fact, the copy I bought in Tokyo is much sharper than the one I bought in HK.
