Image sharpness is excellent bordering on astounding. Even from f/2 the center is first-rate while the edges/corners are already very good. For a measure of this, I have seen samples from this lens alongside the (much more expensive) Canon 135L f/2, and the Samyang is better by more than a stop at the edges and more so at the corners. Stopping down from f/4 to (barely) f/5.6 allows for maximum sharpness over the whole frame. On m43 there is virtually no vigneting even at f/2.

Results from 36MP D800 sensor show an excellent performance of this lens right from f2.0 and all across the full-frame sensor. This is very impressive indeed! With such a sharp lens you can see signs of diffraction setting in ever so slightly at f8.0 and clearly at f11. Distortions are very low.

Anyone using this lens with a Metabones Speedbooster on a GH5 utilizing IBIS? Been looking at the DS EF-mount version for sometime to use with GH5 and GH4 w/ MB XL and occasionally on a C300 I/II.

@sam_rides_a_mtb

Do you expect some issue with IBIS?

@Vitaliy_Kiselev

I don't expect any issues, just wouldn't mind seeing some samples before I make the purchase. Will probably just go to B&H and see if they have one to test. Adorama does not have a store sample.

@sam_rides_a_mtb just remember with manual lenses you need to enter the focal length in first
