Sigma 50-500 OS vs Sigma 120-400 OS vs Sigma 50-500 (no OS)
I am looking for a new lens with more reach than my current 300mm DA. I am packing the K-r. I have been looking into the lenses in the subject line and I was looking for comparisons, personal experience and any info that will help me come to a decision.
I know that there is a 150-500mm in this range too, but I think that one is like 1.5-2.0 inches longer than the ones mentioned above, and about the same weight as the current 50-500mm. While money is an object I have the budget for any one of these...
I am willing to take suggestions outside my scope, and willing to spend more if the bang is worth it.
Let me know if you have any input and I thank everyone in advance for their links, direction and thoughts.
