From a magazine editor's standpoint, this is pretty blah with uninspiring images. Very little useful information.
Roger, at LensRentals said all that needs to be said in four sentences:
"This is really an amazing lens. Little pancakes are cute and all, but usually aren’t of very good image quality. This one has exceptional image quality and does it at an amazing price. Probably the best bargain of a prime lens that exists, anywhere, for anything."
I don't think the reviewer's conclusion has done this lens justice. The innuendo is that this lens is 'quite good for the money', and this is misleading - it's very good in it's own right irrespective of cost. The centre is as good as the 50 1.4 at f2.8, from f4 to f11 it has superb across-the-frame sharpness, and it is a modern 'for digital' lens which controls the digital clipping to highlight' better than made for film lenses IMO
