Extraordinary resolution; slow autofocus

on December 24, 2016

Posted by: Geo44

For my photography the two characteristics most important for a lens are resolution and speed/accuracy of auto focus. My camera is the Sony A7RM2.

The f2.8 GM 70-200 mm lens arrived a week ago and I subjected it to resolution tests, and compared it with several other SONY lenses, including the outstanding FE G 90 mm Macro lens.

Overall the lens proved to be extremely sharp, even wide open, across its range of focal lengths and across the frame. 2 Point type and even a 0.5 point width line (located within 20% of the left and right edges of the target) are resolved at f3.5-f4 and still identifiable at f2.8. At both 70 mm and 200 mm the lens performs at its best; near 100mm it is slightly less sharp. Center resolution is extraordinary from f4 and excellent at most focal lengths, even at f2.8. At the frame corners resolution is outstanding above f3.5 and still near excellent at f2.8 except aound 100 mm focal length where it resolves somewhat less below f4.

As reported by others, my first photography with this lens shows that it is not ideal for fast focusing applications. It often takes too much time to focus even in moderately good light. Avoiding the FULL focus range speeds action considerably. Color and contrast are quite good, qualitatively and bokeh is IMO excellent.

I plan to add to this review after more experience with this lens and especially after I receive the 2X teleconverter. Right now I rate the lens 4 stars.
