Tamron 28mm f/ 2.5 Adaptall-2 model 02B




 Tamron 28 mm f / 2.5 is a fast wide-angle lens for 35 mm cameras. 28mm focal length is sufficient to capture the majority of the overall plans and shots, even for ASP/C sensor cameras. Equivalent focal length for my Nikon D3100 camera with a crop factor of 1.5 is equal to 42mm on a full frame.

Handling and Mechanics

Tamron 28 mm f / 2.5 Adaptall-2 with

Handling compactly and conveniently. In general, lens assembled good, metal and glass. No backlash. The front element has a small size, which at first seems strange for wide-angle lenses. But such a small diameter of the first element does not provide strong geometric distortion at the edge of the frame.

Sharpness

Most of the examples for this review shot at f/ 2.5. This suggests that the aperture f/ 2.5 sharp well.

Sharpness in the center of the frame. Crop 100% of the size of the previous frame.

Sharpness on the edge of the frame, 100% crop size. Observed in the f/ 2.5 chromatic aberrations.

In the center of the frame sharpness is good, and slightly weaker at the edge. At aperture f / 4 sharpness at the edges become also good.

On parallel verticals can observe the level of geometric and barrel distortion. Another example: post Socar in the distance strictly perpendicular, while at the extreme poles observed barrel distortion.

Barrel distortion small, and you can shoot people in a close range. but the distortion is still visible, as does the 28 mm. Tamron 28 mm f/ 2.5 Adaptall-2 model 02B samples

Character and Bokeh

Due to the small focus bokeh is not very blurry, and the object is not much separated from the background. Tamron 28 mm f/ 2.5 Adaptall-2 model 02B samples

Contrast

The lens is multi-coated, have good contrast and generally contrast is good in backlight and side light. Has good color characteristic Tamron BBAR coating. Tamron 28 mm f/ 2.5 Adaptall-2 model 02B samples

Macro

You can not shoot full macro, but a good close-up can be done.

For street shooting camera can be hung around the neck, focus on infinity and simply press the button without sight and attract too much attention. Just remember that after 5 meters in all field. Tamron 28 mm f/ 2.5 Adaptall-2 model 02B samples
