Bigmos test shots

All these shots were taken with a Nikon D200 and Sigma 15-500mm F5-6.3 APO lens with OS. This lens is new this year, and costs under $1,000. I purchased one this November and decided to keep it, based on these shots -- and some more in my airplane galleries. I wish the build quality was better, but I don't think you'll find the optical quality and reach at this price anywhere else.
