The last time I was at Focus on Imaging in Birmingham, I visited the Sigma stall. They had a new 70-200 2.8 there for playing with. It was very nice but the one on the stand had some pretty awful front focus (not a little) and the big 300-800 f5.6 was a lot of fun....but it was soft wide open over 500mm. Pretty sharp under that focal length....but what's the point in having an 800mm f5.6 if you can't use it wide open? My 400mm f2.8 L IS is sharper with a 2x TC and costs less. I had a go on their 500mmm f4.5, which was nice but again didn't compare to the Canon version. At that point I figured I was done there.
I still own and use a Siggi 12-24mm mkI, which is still a pretty unique lens in the market place. Quality control was awful with this particular lens, but a good one is a good find. I think it's amusing that Sigma have bought out this dock thang....getting us to pay for a device to correct their awful QC and on our time too....come on Sigma. I suspect that Sigma's QC is going to drop even further now...and they will blame their userbase for not stumping up the cash for the USB dock.
for new 70-200 do you mean the lens that won as the best expert lens at tipa awards 2011 or something newer? had the same lens and i had to adjust focus with a +3....so? i had to adjust a canon 70-200 f/4 with a +7...the canon was ff "badly"...lol!
and could you tell me why canon services provides by payment the adjustment of focus for lenses? i do not believe they fix sigma lenses.
and now the brutal fact...sigma 35 mm destroys canon offering costing significantly less...40% or so
I didn't say when I went to Focus on Imaging, it was just around the time for their Macro HSM mk 1 I think. Again it was so far out of adjustment, I called over the attendant and he confirmed it. And then put the lens under the counter with a post it note on it. It was worse than my old copy.
It's been surprising how many 70-200mm f2.8 lenses Sigma has put out over the years. I'm assuming this is to correct various design faults with each successive model. Other brands like Nikon or Canon tend to get it right first time and let that model run for a good 10 years or so. That said, I took some great pictures with my old copy.
My 70-200 EX HSM f2.8 (new at the time) was so far out of calibration...it had to go to Sigma twice with the Camera. It was bad. I'm not going to re-tell my Sigma woes here again, I did that a few pages back. Hello if you are new to this thread
I've sent only one lenses back to Canon for being out of Calibration, which I did under their 1 year warranty. It didn't cost a thing and came back perfect.
Yep, it true about the new Siggi 35mm, it's a fine lens from Siggi. I don't think it destroys the Canon, but it's a sharper lens. I've had my Canon copy for about 5 years now and I've taken a lot of photos with mine. It's easily paid for itself many times over. The Siggi fisheye's are very good too and I particularly have a soft spot for their 12-24mm, although my copy had been back to Sigma twice.
