This Tamron (which I use with my Sony A77) is an excellent compromise between quality (high end) and prices (much cheaper than Sony's equivalent) Unless you are a pro and track every little plot of failure (and even then it must have to look good), it has everything a great and offers both a beautiful light and a very effective zoom ( 450mm equivalent in full size) He is tall and massive but still fits in my bag Nothing to say about the product or on the Amazon service and delivery
