Mirrorless cameras, could they really be a replacement to existing DSLRs.
The DSLR concept was invented for object viewing using a film camera.
Using a digital sensor with a high resolution Optical View Finder and sensor auto focus eliminates the need for a big, slow, noisy, moving mirror.
It's only a matter of time when essentially all handheld cameras will be mirrorless.
A lot of people are arguing: "what's the point of smaller cameras when the lenses are so big anyway?"
The point is not just the size. There is a world of difference in camera speed, accuracy and features as well.
Take a look at the Sony NEX 7 as just one example.
The lenses will be getting a lot shorter too. Compare modern telescopes to old all-glass telescopes.
The same thing is likely to happen to camera lenses.
