A crop factor (sometimes referred to as a "focal length multiplier", even though the actual focal length is the same) can be used to calculate the 35 mm equivalent focal length from the actual focal length. The most common multiplier ratios:
* 1.7ื Sigma SD14, Sigma SD10, Sigma SD9, Canon EOS DCS 3
* 1.6ื Canon EOS 7D, 500D (T1i), Canon EOS 550D (T2i), 50D, 1000D, 40D, 400D, 30D, 450D, 20Da, 350D, 20D, 300D, 10D, D60, D30
* 1.54ื Pentax K20D, Pentax K-7
* 1.53ื Pentax *istD, Pentax *istDs, Pentax *istDI s2, Pentax *istDL, Pentax *istDL2, Pentax K100D, Pentax K100D Super, Pentax K10D, Pentax K200D
* 1.52ื all Nikon DSLR cameras except the full-frame D3, D3s, D3x and D700; all Fuji, Sony (except for the full-frame α 850, α 900), and Konica Minolta DSLR cameras.
* 1.3ื Canon EOS-1D Mark IV, 1D Mark III , 1D Mark II (and Mark II N), EOS-1D?, Kodak DCS 460, DCS 560, DCS 660, DCS 760, Leica M8, M8.2
