Not because of lenses purely down to the crop factor. Prefer APS-C or larger. I don't want 14-140 to mean 28-280. I want to mean something closer to normal. Price between a NEX-5N/7 to EM-5 are close so, I would go for the APS-C sensor camera. Also, i have access to NEX lenses though, would be prepared to go all out for a camera if i had money and i liked the camera.
