Sample photos Tamron 70-200 / 2.8
On a camera with APS-C sensor (kf = 1.6) the camera will have a field of view equal to the equivalent 112-320mm focal length, and the aperture will correspond to the value f / 4,5... Why is that? Because, firstly, because of the narrow viewing angle, you will have to move further. Secondly, the camera's sensor receives 1,6 times less light than a full-frame 35mm sensor. Thirdly, although this does not apply to the previous two statements, the lens on the crop has a drop in sharpness due to the denser arrangement of pixels on the matrix and their concentration in the center of the lens.
On a full frame, the lens works as intended - it has a more flexible picture and characteristics corresponding to the declared ones.
Shot with Canon 300D and Tamron 70-200, mostly handheld. Despite the fierce antiquity of the camera, it has fewer misses than the Canon 60D.
The Canon 60D requires sharpness control when working with the Tamron 70-200, as often there is confirmation of focus, but the photo is out of focus.
