Thanks for sharing your review.

I am looking at this pictures of cows, and it appears to me that there are color fringing at the outer edge of the lens. Take a look at the cow with a white head where the left side of both of its eyes has greenish fringing, and the top of its head to our left there is a magenta  fringing. Similar fringing can be found on the left most cow and the cow behind it.  Is it typical of this 30mm 1.4 lens? I would think it's the lens, but then it seems this particular photo shows most fringing. What's your take about this?

Thanks again,
