This lens is a great Ebay find if you can spot a K-mount version. I have the Promaster branded version. Because it's an earlier autofocus film-era lens, it has an aperture ring. Basically you can use it on an old manual body like a K1000, or switch it to "A" and let an electronic camera body control it.

Mounted to the K-1 I was able to lock focus and hold and follow, and get some crisp shots.

The downside: It does suffer from a little CA / purple haze on occasion, but nothing you couldn't eliminate in post, and it isn't all the time. Also, it's a little soft sometimes at 80, but you aren't buying one of these to shoot at 80mm.

It isn't the greatest but for the price it definitely holds its own. I've seen a few negative reviews about it and honestly the only thing I can think is that age and environment have taken their toll on some of these. Given you find one lightly used (like I did), y... |
