I like shooting motorsport - is the Olympus fast enough ?
I can't answer that I'm afraid although I'd be interested to know myself
- How would you compare the image quality to a full fat DSLR ?
So far looks very good, probably the best IQ of any of the M4/3 cameras so far, seems quite close to the Fuji X-Pro 1 that I've just recently had and people are raving about its IQ, I don't think you'd be disappointed
How would you compare the features/controls to a full fat DSLR ?
Control wise it seems good, again I've only just bought mine but very SLR like in setup, features and controls.
- Can only Olympus OM-D lenses be used ?
The Olympus OM-D uses the Micro Four Thirds lens mount of which there are currently a wide range of lenses by Olympus, Panasonic and Sigma. Its currently got the biggest lens lineup of any of the compact system cameras and it seems to be that theres a lens for almost anything.
