Tamron 70-220mm f/4 Adapt-A-Matic

Best of the lenses in this range I have owned several of the lenses in the 70 to 300 and 100 to 300 zoom range...as far as the aftermarket lenses goes this seems to be the best.. it incorporates modern features like the ultrasonic motor and newer materials of construction. This lens is a little bulkier than several others that is lighter than you would expect. It focuses quickly with the two different brands.. Canon and Sony... That I have tried. If you buy the native high-end lenses from most grand you might get a performance advantage.. but you will double or triple the cost..especially now that use prices are going down these lenses are incredibly hard to beat.

Awesome telephoto lens for travel, portraits, and some wildlife. Love this lens! It is quite compact for traveling. The picture is still quite sharp and usable and I use it adapted to a Fujifilm XS20. The VC (Image Stabilization) really works wonders, even at 300mm; it pairs really well with my camera's in-body stabilization. I'd recommend this best for traveling, casual, or even wildlife photography but it's usable for pro-work in a pinch!

Good Value After reading reviews from others that this lens and the new 70-300mm mark ii from Canon are neck to neck in terms of performance, I decided to give it a try since it costs $150 less than its counterpart from Canon. I have used the lens for a couple times. The auto focus works well and it is pretty fast. It is not a fast lens. I mainly use it for landscape and outdoor sport during the day. It seems well constructed. This is my first Tamron lens so time will tell its durability.
