The Sigma is very good for sharpness and very little vignetting. I have used it
on an MZ-S and projected the resulting slide to 6' to good effect.
You do have to watch out for flare and general contrast reduction when shooting
into a bright light source, and it's essential to use the suppliee lens hood.
It has a very large focussing ring and a good feel for manual focus. You have
to slide the ring to disengage the AF, and also use the switch on the body.
It was my most used lens on a trip to Dorset and Devon in the summer, but since
I got the 24mm f/2.8 A it has seen little use. It's just that much bigger (the
price for the fast aperture I suppose). I might ebay it in the new year. A very
good lens though.

Could you tell more about Sigma 24/1.8 performance (sharpness, and flare
control) ? Have you used it on a full-frame SLR ?
