Hi all,
given that the sensor size of the XTi is 22.2 x 14.8 mm, a lens with a 1:2 magnification would allow me to fill the photo with a object of the size 32 x 22 mm, right? With a 1:3 magnification the object would need to be about 39 x 24 mm to fill the photo, or?
If that is about right then I think I won't need a macro for my work right away (see my other threads) but could do my isolations also with a very good standard zoom, which would also be the much better walkaround lens.
Many thanks,
Michael
