This lens is decent. Image quality seems to be not quite as good as my other 200mm zoom lens, and this is a prime. Still pretty good though. What it has going for it is extreme compactness, and light weight, while still letting in a relatively large amount of light. It's just not quite up to the image quality standards of some of the other FD lenses.

In addition, my model seems to lose infinity focus slightly if I tilt the camera down then back up, even without touching the lens. This is a bit annoying. Not sure if they all do this, it might just be a mechanical problem with mine.

A good lens. I bought this together with the 100/2.8 on a budget (this was during my student days) and it has served me well ever since. The only reason it's not seeing much use is that I don't need this focal length as often as I thought.

I picked up one of these very cheaply, and was pleasantly surprised at how sharp it is, even at f4.8 and f5.6. I got it mainly for candid street photography, so with 200 ASA film and 1/500 shutter speed wide apertures are often the norm, but I´ve got some great shots with this lens. It´s inconspicuous, and it´s compact size, quick and effortless internal focussing and light weight also make it a good street shooter. The built in lens hood isn´t long enough, but at least it´s always on the lens, and is certainly better than nothing. I have a handful of FDn lenses, that all use the same 52mm dia filters that fit this lens too. Very handy! Although the close focussing distance is a useful 1.5m, the lens length doesn´t change during focussing, so at this distance the lens is the approx equivalent of a 175mm non-IF lens. Build quality is typical FDn.
