| comment: | This lens is listed new for $1150, $50 cheaper than the newer, stabilized Sony FE 70-300 G OSS. It doesn't feel any better made than the Tamron USD or even the Sony DT 55-300 SAM. Unlike those lenses it is "Made in JAPAN." It's control grips are in the same arrangement as the Tamron USD, but it actually employs a rear focus design unlike the Tamron. This means there is less weight at the front of the lens and less shifting of the center of mass with focus action. Unfortunately this also gives it a considerable amount of focus breathing. The long end is about 240 mm at minimum focus. The 55-300, 75-300, 100-300, and Tamron 70-300 USD zooms all maintain their focal length at minimum focus. The front barrel and front lens element extend with zoom the same amount as the Tamron. The zoom action is also quite heavy and a bit uneven much like the Tamron. The 55-300 and 75-300 D zooms have nicer zoom actions. Despite the rear focus design and SSM designation it doesn't seem to focus any faster than the old screw-drive x-300 zooms. The II designation means it supports the faster communication rates introduced with the A77 and DT 16-50 F2.8 SSM. It also means that like with the 55-300, the Kenko teleconverters will not adjust the focal length and aperture values on the recent SLT bodies. It does allow 2 extra FPS of AF-C tracking on the Sony A9 with the LA-EA3 and 4x better tracking on the recent SLT bodies. The Tamron USD zoom does not support this faster communication speed. It doesn't quite match the central sharpness of the 55-300, but it has less chromatic aberrations. The focus breathing arguable makes it a downgrade compared to the Tamron 70-300 USD. It is very uncomfortable to hold for several hours on the A68. |
