jcs Posted June 16, 2014 Share Posted June 16, 2014 Since the A7S provides a Super-35 crop mode, it would appear the NEX to EF SpeedBooster would work with the A7S, providing another stop of light. Image quality for the crop mode should be decent as Sony appears to have a high-quality scaler. Bob Wall 1 Quote Link to comment Share on other sites More sharing options...
