I have Nikon D7100 with Nikon Micro 105mm F\2.8 and Tamron 16-300 F/3.5-6.3. The crop factor for the D7100 is 1.5; so because of the crop, the Nikon 105mm is LIKE having a 157.5mm and the Tamron looks LIKE 24-450mm, that's ok with me. That is the same thing with the aperture the 1.5 crop applies?. So I don't have a F\2.8 it is a F\4.2? And the Tamron is not F\3.5-6.3 is a F\5.25-9.45? :cry:
You're right. You have to play with the math if you want your photos to look like those someone took with a full-frame camera.
