Zoom lens shading

2004-06-12 Thread Cotty
Okay folks, here's a gen-u-ine question with gen-u-ine Pentax content. In Washington I was able to crack my pile (blecch) and get to grips with a new lens, the Canon 24-70 2.8 - and immediately I noticed it did one thing which surprised me. At 70mm, the lens is compact (LOL) and at it's 'normal'

the DA 16-45 works the way yours does. no other Pentax zoom i tried works that way. the Sigma 24-70/2.8 gets longer when zooming wider. Herb - Original Message - From: Cotty [EMAIL PROTECTED] To: pentax list [EMAIL PROTECTED] Sent: Saturday, June 12, 2004 11:34 AM Subject: Zoom lens

My Sigma 28-70 f3.5 (KA mount) does this - it also comes with a metal lens hood that I leave on full-time to protect the zoom mechanism. I like the feature. :-) Of course, now that I have an M50 f1.4 and a M28 f3.5, that zoom has been consigned to the spare-lens drawer :-) S Cotty wrote:
