View Full Version : Which L zoom

23-06-10, 11:13 AM
I am on the verge of ordering a new 7d :D !!!! to replace my old and well used 300d ...which replaced an old EOS 620....which replaced....never mind. I am confused over which is the best L lens to consider there are lots of conflicting views -I am looking at the 24-70 f2.8L of the 24-105 IS f4L. To further add to the confusion I was also told to think about a 15-85 IS USM??
Please can some one help clear the fog!!!

what do you want to use it for. the canon gets good reviews so does the sigma which is a lot cheaper.

One of the possible reasons for the conficting reviews is it depends whether the lens is used on a full-frame or APS-C camera. Some of Canon's full-frame EF lenses are great in the centre but go soft towards the edges. The 17-40mm L is a classic example. This means that whe fitted to an APS_C DSLR like the 7D the quality is great, but on a 5D you start to see the mushy edge definition.

We haven't tested the 24-105mm but we liked the 24-70mm f/2.8 when we reviewed (http://www.whatdigitalcamera.com/equipment/reviews/lenses/1184/1/canon-ef-24-70mm-f-2-8l-usm-review.html) it. We also found the Sigma 24-70mm f/2.8 (http://www.whatdigitalcamera.com/equipment/reviews/lenses/27069/1/sigma-24-70mm-f-2-8-if-ex-dg-hsm-lens-review.html) to be exceptionally good too.

Thanks all.
Reviews and all aside - I found a bargin used 24-105 F4L which was too good to resist so I dropped for that - If it turns out not to be a good decision I can part chop it for a 24- 70 or something else later - and she who must be obeyed will have forgoten th e 500 I have spent by then :D I will keep my old kit 15-55 which is poor but will be ok for now and then perhaps a 16-35 F2.8 :D :D. I may need to find a second job...
