Tamron AF 70 300mm f 4 0 5 6 Di LD Macro Zoom Lens for Konica Minolta and Sony Digital SLR Cameras

It’s never been easier to capture great action shots than with the Tamron AF 70-300mm macro lens. Delivering superior image quality for both digital SLRs and 35mm film cameras, this flexible lens lets you zoom in extra close when shooting moving subjects, such as athletes on the field or children running or playing. When used with a digital camera, the lens does even better, producing a super-telephoto 35mm equivalent of 465mm–unbeatable in almost any other lens.

Macro Switch
The lens offers an easy-to-use macro switch that lets you alternate between the 180mm and 300mm focal lengths, letting you enjoy true macro photography with a telephoto effect at a maximum magnification ratio of 1:2. The minimum focus distance, meanwhile, is 59 inches from the subject in normal shooting ranges, but when you flip the switch, you can get as close as 37.4 inches. And as an added bonus, the lens boasts a nine-blade circular diaphragm that provides beautiful soft-focus imagery for a professional result. Now you can showcase all your photographic talent with close-up shots of small flowers and insects in parks or in the wild, or any other beautiful small object you discover.

Coatings
Tamron has also adopted various countermeasures against ghosting and flare, common problems in digital photography. The lens employs internal surface coating and new multilayer coating technology to minimize reflections that occur when light enters through the front element, while also reducing image-degrading effects caused by the imagers themselves. The strictest quality control standards were also applied to increase resolution performance and prevent flare due to aberrations, resulting in a telephoto zoom lens ideal for photography with digital SLR cameras. This is one lens you can use with confidence.

User Ratings and Reviews

5 Stars Nice for a telephoto (as a secondary lens)
This is a nice telephoto lens. You will need a wide angle lens for general photography. The macro function is a bit ackward since you must be 10′ away from anything you are trying to shoot. Overall, I would buy this lens again for my Minolta Maxxum 5D. I put a skylight filter on it for protection.

5 Stars i love this lens
i love the tamron it works great and for the money it was a great deal. i love the macro feature on it but it took me a awhile to figure out how it works. i am glad i bought this lens and have no regrets. if i had to say something bad about the lens it would be that sometimes its hard to focus in low light and that the directions with the lens are not much. not that you need alot of direction with a lens but it would have been nice to have more on the macro feature.

5 Stars Great telephoto lens for the money
I have used this telephoto lens with filters, with teleconverters and it works seamlessly with my Sony SLR. No problems noted. I highly recommend it to anyone looking to supplement their kit lens. It also definitely makes a difference that the stabilization for the Sony is on the body of the camera and not dependent on the lens like Canon or Nikon.

5 Stars Good Product.
It works with the A300 and it takes great shots. Don’t get your hopes up to high for the Macro setting though. While it works well enough it is not a substitute for a Macro lens.

4 Stars I like this lens
With the rotating front lens when you focus the use of a polarizing filter is a 3 step process. I like this lens.
