Hi Walter, re: the Sigma Glass you inquired about. I have experience with three of their lenses over the years. The 'best' was a 'fast' 28 for the EOS mount (f1.8 iirc) I scooped up on via a clearance sale from an ad in Shutterbug (it was a while ago!). For sub 11x14 prints, in low light, or where somewhat noticeable distortion wasn't an issue - it was very nice. For a Hundred Bucks for a fast af prime, even nicer. The funnest was a Full Frame Fisheye (14mm?) my good friend had in Konica mount. Well built and a pleasure to use. The worst lens I've ever used on any slr -bar none- was a push-pull 75-300mm AF Zoom I regret helping him purchase for travel pix with his 35mm EOS Rebel mk1 (the very first model). Poor AF, Poor Image Quality, and Poor ergonomics. The reputation I've seen in the 'eos forums' is that select lenses from their line up are great, but build qualities can be quite variable even with 'identical' lenses, so choose a good retailer to avoid exchange/refund issues if you catch a dog lens. Lensrentals.com has some interesting 'repair rate' data on their inventory and comments on lens quality on their site you might want to give a look see. Also a good place to rent something before committing to buying it - especially if you can't touch-n-feel a lens prior to purchasing it. I know that sometimes I'm really excited about x,y, or z, but a few seconds after picking it up or bayonetting it to my camera I know it's something all wrong for me.
