I shot about 150 pictures with this lens in pretty much the same setting, so I didn't have a variety of shots. It's very sharp wide open, but contrast seems low, which is normal with this kind of lens. I expected worse, actually, because this lens has more haze than the 5 inch f4. Even with a long hood, most pictures still exhibits some haze, but it cleans up quite easily in post, as you can see in the sample pictures below. I much prefer the rendering style of the 5 inch f4 than this one, but it's by no means very bad. Besides, I haven't used this lens too much yet, so I shouldn't really draw any conclusions until it see more use. It's definitely worth the time it took to put it together, and the very low cost. Ugliness aside, it has potential inside.
