Pros: – Very sharp straight from the maximum aperture. At f/2.0 is sharp almost ont he entire frame (with very little loss on corners) – Negligible distortion – Very compact lens – When using the converter EXIF data gets correctly transmitted
Disadvantages – close focus point could be…closer – The fisheye converter on the 28mm lens is quite heavy – Not really a very good bokeh (but that’s something the lens is not designed for)
