Sony DT 55-300mm F/4.5-5.6 SAM review.
On the plus side, contrast and resolution are quite good at the maximum apertures at all zoom lengths, but stopping down to F/8 adds a little more contrast to the image. Distortion is generally well controlled, and is not a problem at all with in-camera lens corrections. Also, light fall-off is not an issue, even when shooting in RAW with no ‘shading’ corrections.
The only real downer is the focusing method, it’s the same as the 55-200mm and 75-300mm, which extends and turns the front section of the lens; bad news for filter users.
