What is the difference between a movie lens and a SLR lens?
5. Film lens production process is more exquisite, but the demand is not large, so expensive, ranging from hundreds of thousands, as many as millions of dollars
??
4. Film lens is stepless, can be arbitrarily changed, that is, between the two files can be arbitrarily put the aperture. The SLR lens F1.2, F1.4, F1.8, F2.0 ... ...
2. Movie lens "aperture" unit is not F value, but the T value
??
3. The resolution of the film lens is not high, compared with the SLR lens, the film lens contrast is greater, that is, high sharpness.
Anyway, we are not professionals, I simply answer the next.
1. Film lens all for the manual mode MF, SLR are generally automatic + manual.
