7. Coma and astigmatism

In the case of the Nikor 28-300 mm VR the coma behaves quite untypically. In the DX sensor’s corner at shorter focal lengths it is low and it increases to medium at the longer end. In the full frame’s corner this trend is reversed. The coma is quite significant at 28-50 mm, medium near 100 mm and slight in the 200-300 mm focal range. You can see it perfectly well in the crops below.

If you deal with lenses featuring a lot of elements and a wide focal lengths’ range it’s always worth looking more closely at astigmatism result – it is not only an indicator how the lens was corrected by the optics constructors when it comes to astigmatism itself but it also checks whether the mechanics of the device manages to perform a precise and appropriate shifting of movable elements.

It seems that in this case the optics constructors and the mechanics constructors did a good job. The average difference between vertical and horizontal MTF50 values amounted to only 4% which is low. The Nikkor can be praised in this category for sure.
