Not bad with a bit of deduction

Here now a lot has been written about this shard. Since October, I use it on a D5100, this lens is my current favorite. In many reviews we read of fehlfokus. And here I also subtract a star because in low light, that is, where I still really want to score points with aperture f2.8, my copy tends to focus Front. In daylight the focus sits however. My Nikkor 1: 1.8g 50mm This reflects better my other Tele shards have similar problems.

At 17mm the distortions are not underestimating, software like Lightroom knows the lens and corrected reliably. At aperture f2.8 the sharpness is just ok, the beneficial Aperture is F5.6. And thus succeed impressive sharp photos.
