Excerpt: lens has been returned twice already for repair. once needed new focusing gear.problem is you dont realize there is a problem till you review your pictures and see they are not sharply in focus.would not recommend this lens for that reason.
I compared it to sigma 18-250 on Sony A55 it took better pictures at the long end of Osprey inflight

Summary: works very well on my Nikon D5100, I compared it to sigma 18-250 on Sony A55 it took better pictures at the long end of Osprey inflight ,then the Sigma. That may be me or the difference in cameras .I like them both. Would be hard to say which I like best.
Summary: I was looking for a lens that I could use as an all purpose lens, rather than having to change lenses all the time. I'm not a professional photographer by any means, but I love to take pictures....landscapes, family, wildlife, flowers, etc.
