We see the best coma correction in the middle of the focal length range – you don’t notice it there almost at all. Its influence can be seen, though at 42 mm but still its level is low. The highest level of coma can be noted at wide angle. Although the coma is noticeable there, it is not huge. To sum up our impressions are rather positive in this category.

We have no reservations when it comes to the degree of astigmatism correction. The average difference between vertical and horizontal MTF50 function values amounted to 3.6% which we consider to be a very good result.
