Should I change my lens?

[munge]

Have a Sigma 10-20mm lens that I bought the other week after deciding that I needed something wider. Ended up with the Sigma after the bloke in the shop I was browsing in felt it was not really any different than the equivalent Canon lens.

However the more I think about it, the more I wonder if it's a false economy. Obviously it's got an extra 2mm of zoom which I can't imagine and assuming that the picture quality is comparable (which many people seem to feel as long as it's a decent version), but it does have a wider maximum aperture. Would I really notice the difference to justify the extra £150-200 it costs?

Feel like I'm being a bit of a cheapskate going for the Sigma. Should I just get out the cash and get the Canon 10-22 instead?

I appreciate there have been lots of threads on the pros and cons and the image on mine seems okay on the few photos I've actually used it for, just don't want to find I regret it in a few months time and then don't have the option to exchange it.

Cheers! Oh, using a 40D if that affects your assessment..

What do you tend to photograph? I tend to shoot landscapes mostly, I've got the canon 10-22mm and normally have it at f/9.0 or thereabouts so the difference in aperture makes little difference to me, and I bought it because I wanted a wide lens so most of my photos are taken at 10mm. I think the extra 2mm is negligible really and not worth the upgrade alone. Do you do much low light stuff? If you do a lot of photography hand held in dimly lit areas that is the only reason I would say it was worth the upgrade. I only chose the Canon due to hearing about sigma quality control issues and there was a cashback offer on at the time, so the price wasn't too much more.

If you've only just bought the Sigma, I'd suggest that you keep it for a bit longer and see if you do find it limiting at all before spending another load of cash on replacing it.

as long as you have a good quality sigma i dont see any point in changing it, i doubt you would see any difference in real terms

im about to buy the sigma myself

Okay, perhaps it's the snob in me that feels I am getting something slightly inferior beause it doesn't have a Canon brand!

i can see your point but if you are happy with your sigma, then it's a false economy to then go and get the 10-22 instead, just because it says Canon on it?

If you can return the sigma and can afford the canon, i would do the swap.

I still have the Sigma.

The extra 2mm makes next to no difference at the long end.

i went through 2 sigmas 10-20mm lenses and both were poor, got a refund and spent some extra to get the canon 10-22mm, i found the overall sharpness , contrast and colours a lot better

i guess a good copy of the sigma should give good image quality but its a lottery getting one
