Вот пример дешевого сверхширика на ФФ 14мм Samyang 2,8 стоимость 350 $
Хочется посмотреть на полноразмер с кропа на соответствующем ЭФР с подобной детализацией и чистотой картинки ...
Here's a weird truth: I compared this Tokina 11-16mm shot on a D300 to the 14-24mm shot on a D3 in FX mode, and the sharpness is the same except for the far corners wide-open!
What?
Simple: the D3 and D300 have the same resolution and the same sharpness when compared with perfect lenses. The 14-24mm is sharper in the far corners at f/2.8 on the D300 than the Tokina, however, the D3 doesn't have enough linear resolution to see the extra sharpness of the 14-24mm. They look the same when shot against each other this way (ignoring the last few millimeters of the corners) because we're really just comparing the limits of each camera, which are about the same.
