I have the 18mm and the 35mm EF S35 Meike. I tested them against the more expensive Zeiss and Canon EF prime lenses. I prefer the Meike, I like the feel of the lens in your hands and the bokeh. The lens is slightly soft which I like too compared to the colder hue and sharper images one gets with Zeiss prime lenses. The only thing is one needs to install the shims for the backfocus, which I still have to do.
