1. It works out to a magnification factor of 783 . 3 percent. 2. Blue marks hint to additional zoom-in extensions with magnification factor 16 . ]] 3. It works out to a magnification factor of 783.3 percent. 4. New Approach to the Digital Measurement of Magnification Factor 5. In this case, the magnification factor ( " m " ) must be taken into account: 6. Those vibrations may, or may not, be significant depending on their magnitude and the magnification factor used. 7. All previous digital SLRs had a smaller sensor, giving a cropped view ( see magnification factor ). 8. While gravitational lensing preserves surface brightness, as dictated by symmetric lens, the magnification factor ? is given by 9. The crop factor is sometimes referred to as " magnification factor ", " focal length factor " or " focal length multiplier ". 10. Finally a compromise is selected by each manufacturer and results in magnification factors which vary strongly along the film ( 15 %-30 % ).
