I used one for years back in the late eighties and early nineties with film cameras. I was pleased with results from it at that time, but haven't used it since, even though I think I still have it on a shelf somewhere. I later picked up an 80-200mm 4.0 AIS (mint, for about $80) and found I preferred that lens, primarily because it focused closer. Both were good. I've never used either with digital bodies.
I still use the AI 80-200mm f4.5 today. It is a fine lens which shows high sharpness, even wide open, on my D800 body. I've had mine since 1979 and since then the photos it produced were better than the mf prime lenses I had. The only problem with the lens is the zoom/focus ring will get very loose over time. It's even hard to find one today that isn't loose. I also have the AIS 80-200mm f4 and between the two I can't tell which is sharper. From the pre-AI days to when the AF 80-200mm f2.8 came out, it was the zoom lens to have.
Thanks guys, I have the D7000. My AF lenses are 18-200 VRII and AF 50mm. I have the 105 2.8 micro MF and the MF above mentioned zoom. I have been using the 105 macro and now I think I will spend some time with the MF 80-200. I also took my Minolta Spotmeter F out of retirement.
I am taking lots of photos of flower gardens, macros and close ups. I am using this D7000 much like my FM2 was used 20 years ago. I was able to get some great Arizona sunsets back then using this combo and the zone system.
I've been reading the Fred Miranda forum "Shooting with tubes" and this lens is often mentioned as being a good match with tubes because of its good color rendition and the ease of framing and focus with a push/pull zoom. I don't yet have one but I have been using my old (Nikkormat days) 70-210 Samyang with reasonably good results. I would guess that the Nikon would be sharper, but given Samyangs recent run at the MF market, who knows? I have also gotten some surprisingly sharp results from my Soligor 400 f6.3 and an M2 tube. Here is a link to one of the Fred Mirands threads: http://www.fredmiranda.com/forum/topic/1001614/8 Hope this has not been too far off topic. Tom
