Re: 28-70 F4 quiry
That's the one. I bought one and a 24-90 at the same time a few years ago, and shot one roll of slides with each (remember slides???). The 24-90 was clearly better in contrast, sharpness, and light fall-off (not to mention the extra 4mm at the wide end), so I returned the 28-70.

Dave Equine Photography in York Region Yep, this is the one with element seperation issues. It's the main reason I haven't tried to get one of the ones Henry's has on the shelf at the main store in TO. -Adam -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
Re: 28-70 F4 quiry
Yep, you've got it. Elements don't just separate from each other. The rear aspheric element is a composite made from a ground glass portion and a molded optical glass portion, it's this element that breaks down and separates. Too bad as otherwise this is a wonderful lens. I understand that Pentax is now able to repair these but I haven't gotten around to sending my sample in.

Funny you should mention that: I was just at a local camera shop yesterday and noticed that they had a couple of these lenses, new and boxed, on the shelf. I was thinking that when/if they sell, these lenses would be under warranty and Pentax would be obliged to repair them if they experience the separation problem. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
