Quality would still be good.
However, it won't be as ultra wide angle as you might want due to the crop factor.

It would be equivalent to a standard 28 -50 wide angle zoom (in this case 27-64mm)- and superb quality at that.

It would be aprox 27-64mm full frame equivelent.

only with a filter screwed onto the front.

Its performance is very good. For me, the only downside is I thought it was too short at the long end so i got the 17-55 as a more versatile lens.

Yeah that's what I was thinking Mike.that the only drawback.

It really depends on what you mainly want to use it for.

If the 15-85 had been on the market at the time I bought the 17-55, I would really have been tempted and traded versatility for a (not very significant) difference in IQ.


Most of the differences seem to be in colour and contrast which can be tweaked post processing.

How well does it work cropped....? ? ?

Check out " KathyW " PF, That lens has seen service on 300D, 20D, 40D, plus 5D MkI & 5D MkII, She is one very fussy gal to.....Grin

If there is one lens in her collection that is NOT ever gonna be replaced, It is her Canon 17-40mm L.

On a full frame I wouldn't hesitate to get the 17-40, on a crop sensor the extra wide angle on the 15-85 over the 17-40 is invaluable for me.

Personally I found the 17-40mm to be better balanced on full-frame Canon breeze blocks than on a lighter crop-sensor camera. I eventually stuck a Tamron 17-50mm f/2.8 on my 60D, which seems a better match.

Its a great lens although its focal length can be very limiting.

I wouldn't hesitate on recommending the Sigma 17-70

I had a 17-40 on my 40D, image quality was brilliant as to be expected . As has been said previously it is not long enough for a "walkabout" lens. I did find it too limiting so I sold it.
I had a Sigma 17-70 OS which was good value for the money.
However I was offered a Canon 15-85 at a good price, so I got that. I am really pleased with it and wouldn't part with it. Highly recommended from me.

I use one on my 60D, it's my most used lens. I also have the 24-70mm that rarely gets used now that I have the 17-40. Some pics in my portfolio with that combo used.
