SL2 VS S1R M-Glass Comparison

Quick and dirty corner performance test using S1R and SL2.

SL2 on Left S1R on Right. Lens is 28mm Cron ASPH V1 @f2 minimum focus distance. Pretty nice bump in corner IQ from SL2.

Interesting! Thank you!

Have you tested it from greater distance? The effect should be even stronger as the last lens element moves nearer to the sensor.

Wow that is  significant 

yes ..... but the old version 28/2 was by far the worst offender as far as non M mirrorless FF sensor performance was concerned when tested on a variety of bodies.

@photonc Thanks a lot for that comparison. May I ask, whether you were using a tripod placed in the same distance, same ISO and same shutter speed?

The amount of loss of quality may vary between different M-lenses, but there obviously is a noticeable difference bewteen SL2 and Panasonic's S1R!

Both were handheld at minimum focus distance with the focus point in the center of the frame shot at 1/100 100 ISO with ibis on. Totally unscientific but should at least give a general direction of performance.
