Ok i was gonna buy the canon 10-22 but the sigma is so much cheaper, i have looked through google and there are very conflicting reports on it.

Im no pro by any stretch and i dont sell my pictures, i only shoot for fun, with that said have i chosen the right lens?

Do any of you guys use it?

many thanks Buzz

I think the biggest issue is QC. I've seen pics from a Sigma where it was soft down the left side of the frame, lens was returned for an exchange, the next one was similarly soft down the right, also returned for an exchange, that one was soft down both sides. Poor guy was obviously unlucky!

Take some good shots of trees etc at say f8, if its sharp right across the image its a keeper !

I have heard from others about stopping down, i will have a go through the stops and check the quality, ty

Sigma produce some awful lenses.

They also produce some amazing lenses.

Quality control is poor, which is why the above is true. I've had God awful copies of lenses that get decent reviews, and I'm the current owner of one of their most slated lenses (120-300 f2.8); I must have the best copy ever as it's pin sharp, has excellent contrast and excluding a minor back focusing issue (which is easily correctable), is amazing.

Best bet is to check it out when it arrives and see if there are any obvious issues, otherwise it'll be a keeper.

Out of interest, is it the constant aperture version or not?

i have two sigma lenses, 18-50 2.8, 18-200 3.5 and they have both been very good lenses, iv only just got the 18-50 so its still in its infancy, but the 18-200 has been working flawlessly and tbh i havent really noticed any issues.
I bought the variable aperture version.

I own one (the older variable aperture one), stopped down which is I always do anyway the lens is very sharp over most of the frame.

The biggest factor is going to be your ability. These lenses are very, very hard to use correctly, most people simply see it as a way to squeeze more stuff into the frame, but that invariably leads to poor photographs.

You have to think much more carefully about compositions, perspectives, how the viewer will parse the photograph, how to manipulate leading lines etc.

thats good to know i will bear that in mind
 
hahaha, my 18-200 is an all rounder and now i have my 18-50 it never gets used! I will try and use the appropriate lens for the job ;)

Im going to buy a nifty fifty lens next, probably the 1.4 if i can find a decent one on flea bay :)
