Hi Colin,

There doesn't seem to be much in it (Zeiss V Samyang) in terms of Resolution/MTF and Coma performance.

The Samyang 135 f/2

The Zeiss appears to show marginally better than the Samyang in terms of Resolution measured MTF50, but the Zeiss was "measured" with a Nikon D3x (24.5Mpixel) vs the Samyang 135 tested with the Canon 5D MkIII (22Mpixel) so I wouldn't read too much into any marginal 2-3 l/mm resolution difference.

The coma test on both lenses also appears excellent, maybe slightly better for the Samyang, but ....????

Best
