I am thinking I need to replace my 17-85mm EF-S lens. I knew when I bought it that it suffers from vignetting at the wide end (~17-25mm) but is otherwise a good lens.

However I think Id rather get a lens without this issue, and maybe a little more range. Any suggestions? Budget wise Ill need to sell the 17-85mm (Im hoping maybe £200) and my Sigma 70-300mm sh*tty lens that hasnt been used at all since the summer, which might be £75, So budget is maybe ~£350 new or second hand.

Ive got 10-24mm Tamron, 28-135 Canon, and the 150-500mm Sigma, these make my best set and you wont do that much better elsewhere.

I also have a 70-300mm Canon, cheap, with fairly limited facilities. Reason I keep this is simply that it is far lighter and easier to carry than the Sigma.

The 28-135 is the one I was debating over mostly, it was that or the 17-85mm. Ended up with the 17 on the assumption that if Im going to the lakes for landscape stuff wider is better, though 17-28 has bad vignetting. Id read that the 28-135 has it too though?

Example of the vignetting at the wide end:

I use mine on a small sensor camera, it doesnt have any vignetting on that, My brother has the 5D and his pictures seem OK with it too.

To test take your camera into a shop and ask them if you can try one out on it?

most zooms will vignette at their widest setting, particularly at large apertures. If youre going to be using ~17mm a lot and want to avoid this, something like Serious 10-24 might be a good option as you wont be pushing the extremes of what it can do.

how is your sigma 70-300 sh*tty?
I bought the tamron version in Jessops sale.
Bought it to replace my canon 70-210 which is supposedly be a better lense, but I cant get good results with it.
I should get more for the canon than the tamron cost me..

I look at these

My canon gets nowhere near them results.

The sigma is very very soft, and slow. That is how it is sh*tty.

I think they actually released a slightly newer (and better version), mine is the older one. But you cant expect much from a lens with that much range for that price.
