Handling and Mechanics

The lens has a comfortable ergonomics and dimensions. Nice to hold it in your hands. Construction also good. The front lens has a rounded bulging shape. Tamron 35-70 mm f/ 3.5 Adaptall-2 model 17A

Focusing and Zooming

The lens has a wide rubberized focus ring that rotates 270 degrees. A lot of the rotation at close range. Because of this macro lens. It can shoot close-up at reproduction ratio 1: 2.8, as indicated by the label on the barrel. When focusing, the front element rotates. This can be inconvenient using gradient filters. The focal range is adjusted by turning a ring segment, which is located near the lens mount. In the normal state, the lens has a focal length of 70mm.

Contrast and color rendition

Lens multicoated (BBAR). It much afraid of the side and backlight. It is therefore recommended to always use it with hood. Tamron 35-70 mm f/ 3.5 Adaptall-2 model 17A Samples

Summary

I like this lens. In a dark room of course aperture 3.5 is not enough, and sometimes it is difficult to focus by the green dot (on Nikon D3100). It is also important to remember about the side and the backlight and the rest of it is very convenient.
