no problems also the sigma is 2 and a half times cheaper and is still an amazing lens, easily my favourite
There seems to be some serious purple fringing going on in that sample. I just happened to have your 5D2 10028 test-1 sample up to compare it to. The image with the 10028 on the 5D2 looks much better, and sharper than the 5D3 with the Sigma Lens.
Yep. the sigma has a fair bit of purple fringe at f1.4 (still sharp though) by f2 its all gone and gets sharper still
I definately feel the 5D2 is sharper, i'm hoping its all related to the dogdy raw converters we have access to at the moment. typically i shoot this lens at f2 for these reasons and to avoid too many DoF problems. I do find lightroom removes all the purple though in lens correction
And yeah that 100f2.8 is such a nice lens soooo sharp
