Moon size with different leses The following images are 100% crops of the moon, taken with a Nikon D70s at different focal lengths. The Nikon has a 1.5 crop factor, so to get a similar image in 35mm film, you need to multiply by 1.5. Focal lengths marked TC are taken with a 2x teleconverter, and may therefore be somewhat less sharp.
