Bests & Worsts Reviews from Amazon

Works great with A7. For the price, you can't beat it. Before you whine about the performance, put the current firmware on both your camera and lens (as of this writing, that would be 3.20 and .2 respectively), and then go into the settings and enable Phase Detect. AF is fast up to F4, after that the camera needs more time to hunt. For someone like me coming from a Canon 40 2.8 STM w/Commlite adapter, this is not a big deal, and is still way faster than any adapted lens. Corners are soft and hazy wide-open. In any case, 99.9% of the time your audience is going to marvel at how blurred the background is, while the other .1% is measuring the bokeh balls with a caliper for uniformity. Who cares? It's a portrait lens, for crying out loud. Stop-down if it bothers you. Beyond F5.6, this lens is sharp as nails and produces landscape scenes with stunning detail. This lens is light-weight. I can see myself traveling with just this lens. It's a 50mm lens, it produces beautiful images on the A7, and most importantly, it doesn't cost half the price of the A7. Believe me, nobody is going to look at your image shot with this lens and say , "Aha! You didn't shoot this with the $900 Zeiss!".
