The Sigma 500/4.5 was my very first lense, and it is still the lense I use for almost all of my photos. The only things I don't like about it is that it doesn't work well with converters, it lacks os/vr and I have a feeling that focus could be more accurate. I also would like it to be slightly longer, but that is another question.
So now Sigma comes out with a new Sigma 500/4 Sports that seems to solve all my issues and be on level with the Nikon 500/4. I have found two reviews so far (one is in dutch):http://www.photographyblog.com/reviews/sigma_500mm_f4_dg_os_hsm_sports_review/http://natuurfotografie.nl/review-sigma-500mm-f4-dg-os-hsm-sport/
I would like to hear what you all think about this lense. Two qestions that comes to my mind are:
Will there be any reason to buy the Nikon 500/4 instead of this new Sigma lense?
Will Sigma continue and come out with a 600/4 and/or a 800/5.6 in the Sports series?
