I gave an example here with Tamron, and so Nikon is good in every respect in terms of pictures, except for chrome aberrations, they are not strong, but they are compared to Tamron. Otherwise, Tamron loses. But as already mentioned in the reviews, dust particles, that is, small ones, in my copy, indeed, if you look from the rear lens by pushing the aperture petal with your finger, you can see a few micro dust particles, such particles will not affect the operation of the lens a little, because they do not pass through the rays will create a hindrance. But still, it’s unpleasant that the lens is top-end and made in Japan, with such small flaws, it doesn’t look like them. We could have tried! In order for me to rate 4, I need a worthy analogue of this lens! - He's gone! Do not spare expensive filters for such a lens, but it is best to take the B + W Schneider 010M XSPD UV-Haze MRC nano 77mm - This is super glass, you will not find better. I use this lens on the D800.
