Let me start off by saying this is not a full in-depth review of the Sigma 50-500mm f/4.5 -6.3 APO DG OS HSM zoom, but rather a quick look.
The other night I was out shooting some skyline shots from a good distance from downtown and I thought this might be a good opportunity to show the insane zoom range of this lens. All though these conditions were not great for image quality review, I can tell you from previous use of this lens that things get a little on the soft side at 500mm. However, when your able to go from 50 to 500 without switching lenses you gotta let somethings slide. The OS (optical stabilizer) on this lens is great! You can actually use it hand-held throughout the range. I would suggest using a mono pod with this lens though, as your arms will get a radical work out lifting this heavy beast. In short, I like this lens. The image quality is great on the shorter side and get’s a little soft near the end, but I can live with that.
I’ll do a full review of this lens sometime in the future.
Thanks for stopping by, Rob
