When it comes to the coma, its correction level should be considered as medium. It is not easy to correct this aberration in fast and relatively wide “primes”. The Samsung fares moderately well here. It would be difficult not to notice, though, that in the equipment of this type we’ve seen far worse performance.

The astigmatism correction looks a bit better. The average difference between horizontal and vertical MTF50 values amounted to 6.9% which we consider a good result.
