I take this type of image to see how the lens reacts to these high contrast areas. No CA seen here at all. Mayb the light was too good for this one but sometimes I like how the image turns out. Plenty of detail in this one. I believe the lens cost me in the region of 20 Euro. There are some real bargains out there if one has patience and is willing to shop around a little. Some of these cheap legacy lenses are the best I have, costing very little.
