[QUOTE="Rick M, post: 348921, member: 4399"] Mike is experiencing DoF shift on his 70-200 f4. As a test my results are as follows, 200mm about 4 feet at f4, 5.6, 8 and 11. Focus point surrounding the "12". I'm satisfied that my copy is maintaining about 1/3 DoF in front of the focus point on all settings. Mike, please add your results to this thread and we can compare. Perhaps a few other members might join in.
