Wrapping up for now my series of test shots taken with the Sony FE 70-200mm F4.0 G OSS lens. I'm sure I will be uploading more pictures in the future, but for now, I'm done!
Over the past few days, at the risk of dumping a lot of photos onto flickr in a short period of time, I have tried to present a fairly wide range of photographs shot with this lens. These are not scientific tests - I'll leave it to the bloggers and sites that do these. I hope I have shared some insights on what it looks like as a practical tool, and I hope anyone using or considering the Sony E-mount mirrorless system finds these images as a useful point of reference.
The lens comfortably resolves 24MP on an A7-II, and shows its potential to deliver higher resolution on an A7R when not affected by the shutter vibration problem of the A7R. I am looking forward to testing it on a future A7R-II or A9 camera with a 36MP or 50MP sensor.
I have not tested the comparable 70-200mm F4 lenses from Nikon and Canon, but this Sony lens must be at least as good. In fact, with the new Sony A7-II, the Sony 70-400 has clearly stepped into the league of the pro DSLR lenses, such as my Nikon 70-200mm f/2.8 VRII.
Last week, I took a number of pictures at a birthday party with both my Sony A7-II + Sony 70-400mm F4 and my Nikon D810 + AF-S Nikkor 70-200mm F2.8 VRII. Except for the slightly softer bokeh with the Nikon, I could not tell the difference between the two images.
Here is a typical comparison: the above is a crop from the Sony combination, and the crop below is from the Nikon combo. Both crops uploaded at actual pixels.
Bottom line, I am very pleased with this light-weight Sony lens in a very useful focal length range, and I would highly recommend it to anyone using the Sony E mount system. Just don't use it with a Sony A7R - I almost returned this lens because I was getting so many weak images, until I realized the shutter vibration in the A7R was the problem, not the lens.
