If the Sigma is going to be soft after 200mm then I'm sure I won't be that happy with it considering there should still be another 100mm available.
Any more advice greatfully received.
Go to Jessops, ask to try both out. Then say you want to think about it. Once you have decided, go on camerapricebuster and buy it from the cheapest place on there.![]()
Will do.
However is the IS worth the extra when also losing 50mm ?
I guess that depends on what you use it for - it should give you 2 to 3 stops advantage over the Sigma.
I'm about to get the 55-250 IS myself. I was going to buy the Sigma, but the Canon got such a good review, I decided to go with that.
have a look for yourself www.photozone.de
if you are interested i've got a sigma 70-300apo lens ,bought new about 2mths ago and have only used it once, pm me if you are interested![]()
I had the non-APO 70-300mm and recently bought a 55-250mm IS, the IS has far better IQ than the Sigma above 200mm.
I did some comparison pics, I'll post them up when I get a mo.
I've only used the Canon, but would thoroughly recommend it - the IS is especially useful if you do any degree of hand held shooting.
There are several threads around with shots from the 55-250 if you do a search - all of my shots (in those threads) are at 250mm and lack for very little. I've only ever applied minimal PP before posting (in DPP).

I got that Sigma lens last week - the 3 comparison pics I took were at 135mm/ 214mm + 300mm - click the link:

Won't have chance to use it again until next Wednedsay on my day off - more pics to follow..........
Part of it may come down to whether you want IS or not as well.
Since having IS I have found it a great bonus, whether my hands are particuarly shaky or not I don't know, but it allows me to shoot better pics in low light conditions - which I enjoy doing.
I will get a thread up later of my findings between the non-APO Sigma and the Canon, I didn't take pictures of anything particuarly special, but they should show a difference.
Bear in mind though that the APO Sigma would be an improvement on the Sigma I had.
