We’ve seen that the a7R is affected by shutter shock. We’ve seen ways to ameliorate those effects. We’ve seen that the a7 is essentially free of shutter shock effects by virtue of its electronic first curtain shutter. What if we put all that together and consider the question, “At its worst shutter speed, is the… [Read More]
Sony a7, M240 with 135 APO-Sonnar
