What is the difference of Compact, Mid-size and Full frame size DSLR
There are basically three different sized DSLRs. I'll use Nikon as an example.
All SLR cameras must have a mirror and a reflex viewfinder. ***
Compact SLR: A "compact SLR" is usually an entry level product such as a Nikon D3xxx or D5xxx. however some mid range products are quite small too, such as nikon D90, Olympus E-30.
