Rob, there are many Mailing Lists and Forums available online for any major brand (Canon, Minolta, Nikon and Pentax) where you will find a lot of that brand specialists who can surely advise you about the brand and third-party lenses you would go with. I myself is Minolta shooter actively participating in Minolta Mailing List for a long time and have been advised and advised myself to others in this regard. I don't know which camera system do you use, so will hold from speaking particularly about something special. One word only: basically all 28-80 (especially those of f/3.5-5.6) are so-called kit lenses produced especially to e sold in kits with low and low-mid specified bodies. They featured by very cheap glass capable of delivering mediocre results, since the main goal of such lenses is the lowest possible price rather then quality. In optics the rule: "you get what you pay for" has almost 100 % meaning...

Sorry about the OT question, but I was wondering if anyone on the list could suggest forums where I could ask questions about lenses? I'm getting a little frustrated by the lack of sharpness in photos taken with a Sigma 28-80 f3.5-5.6 zoom, and I'm wondering just how much difference it will make to my 35mm scans if the lenses were better. Basically I just don't know how much visible improvement there would be in 2700ppi scans from say a decent Pentax, Canon, Nikon or Contax lens. I get significantly sharper results with my 50mm f1.7 lens, but it seems to have colour aberration problems (red aberration). I'm trying to avoid garbage-in-garbage out as much as possible in the scans. :) Replies offlist would be appreciated. Thanks! Rob Rob Geraghty [EMAIL PROTECTED] http://wordweb.com
