Originally posted by jmrsp i recently joined pentax forums and decided to introduce myself. i bought my first pentax, an mx, in 1979, and less than 10 years later bought an lx, which i've been shooting with since. i still have the mx…in a box. i use 3 lenses: vivitar series 1 70-210/f3.5, tokina atx 35-70/f2.8, and a pentax 400-600 reflex zoom. also i'm looking for a fisheye zoom. i saw a cosina 19-35mm af for sale. anyone use this lens on an lx? i'd be interested in hearing from you. oh yeah, i'm still mourning the demise of kodachrome 200
Welcome to the forums! That reflex zoom you have is fairly uncommon. How do you like it? As for fisheye zooms, I think the Cosina you're referring to may in fact be made by Cosina, but I've seen 19-35s in a variety of brand names, most notably Vivitar -- which was probably made by Cosina. As for the quality of it, I don't really have any idea, but when it comes to trying to figure out just how good -- or not -- an optic is, I like to go to flickr.com, type the name of the lens into the search panel, and then look through the images that were supposedly taken with the lens in question. You know what? Just for grins, I did that just now, and found a bunch of rather spectacular shots:

If they are indicative of the actual quality of the Cosina 19-35, all I can say is, I
want one! It's rectilinear, though -- not a fisheye.
