I bought a Zeiss 135/2 APO lens for my 810. I've been testing it for a while now and not sure I will keep it. Two problems have cropped up which I would like forum members to comment on, please. Now with a lens which is designated APO I expect it to be exemplary. The first problem is shooting into (or toward if you prefer) the sun I'm getting some CA. See first image. The partial halo around the sun and the CA at the bottom of the image. It's not terrible but more than some of my other lenses which don't carry that vaunted APO lettering.
The second problem is moire'. I've attached a crop of another test image where the moire' is very noticeable in several of the palm fronds. This does show up when printing large. I tried a Gaussian blur removal which didn't work and increasing the radius just destroyed the image. Now in my landscape shooting I don't expect this to show up but it might.
Maybe at half the price of my Otus I should just shut up and shoot.
All comments appreciated.
