I shoot the Rolleiflex and the Fuji GF670. The quality of the picture from either lens is great. The difference between the two is speed of use. I can easily shoot my grandkids on the move with the Fuji. I am not as good at using the Rollei that quickly. But the Rollei was used by news photographers back in the day so I am sure it can probably be done with enough practice. At least that is what I keep telling myself.
