New To Me Lens

Hi, I just picked up a Pentax ZX-60 camera with a like new SMC Pentax- FA 1:3.5-5.6 28-90mm lens for $20 at a local thrift shop. I'll be getting rid of the camera and using the lens on my K5. I've played with it a little. I've got a 18-55mm, a 135mm A series, a 300mm A series and a 28mm A series plus a 600mm totally manual lens. I'm going to have to experiment a little with the aperture only mod and the totally manual lens. I'm watching for either a 55-300mm or a 75-300mm in autofocus. We've got a Downy woodpecker working one of our trees and I'm going to try and get some pictures. Still learning the new camera. Could be making a trip to southern Idaho to shoot Shoshone Falls (the Niagara of the West). It's running a bunch of water this year. Pretty spectacular. Jim

Use a hood on the lens if possible. Stop it down a bit more aggressively as well. The old FA's on an aps-c tend to be a little washed out due to letting in more light (larger image circle). I have the F 30-80 and the FA 28-105 (and had the FA 80-320 until fungus claimed it). Any FF era lens should be stopped down more than you're used to, especially in bright light. If you're out in the sunlight, I'd definitely recommend starting around 1/3000 @ f8+, and cut the ISO down unless you're trying to do macro or moving wildlife/action.

If your intent is to shoot landscape, then try for using a wider angle lens, like your 18-55 between the 18-35mm range at around f/5.6 then just lower/boost your shutter speed while keeping your ISO fairly constant between 100-640 depending on how strong the lighting is.

FA 28-90 is an interesting lens. Not particularly sharp but I have sold some images taken with it as abstract art. Definitely use a hood, and stop down. It is worth every penny of that $20

Please get the DA 55-300, it is well worth it. The DAL version can be had little more than the old FA lenses and it is modern glass and designed for digital.
