Some of the best glass on the market will produce coma

Takes great shots where the glass is just super clear.

The photos turn out super sharp, as of right now its the best glass in my bag.

This is an amazing lens for the price, (i paid 320 for the AE version for Nikon) very wide angle lens with good clear glass.

The photos turn out super sharp, as of right now its the best glass in my bag.

The lens itself seems to be just fine, the glass was great and pictures come out very well when in focus

At f8, it is the sharpest lens I own (including pro Nikkor glass) - nice contrast and colours.

Some of their lens aren't at all in my price point and it isn't for the sake of not buying excellent glass, it because of use vs price

Not as sharp as I'd like, as my kit lense are much sharper.

While this wide focus adjustment range is a nice engineering achievement, in close shots (especially one meter or closer as well as in low light conditions), it however becomes difficult to see which point is in focus since in the small view-finders literally everything appears in focus

That strikes me as so odd that it's probably something I'm not doing right
