With a crop factor of 1.6 for my Canon 500D, all lenses' focal range will be adjusted upwards which have implications for the end result like framing, effective focal distance, image distortion etc. This is from my newbie's perspective. So choosing lenses have to factor in the crop factor?
With a lens of 70-300mm will now mean 102-420mm ... may look good on paper but this may not be what a photographer needs for example he wants the widest angle lens say 10-22mm but he will never get it as it translates to 16-35mm with crop factor.
How then can a person take photos with the desired focal length of 10mm for example in a body of Canon 500D for example?
Thanks in advance for your kind replies.
