Meike 85mm f/1.8 Performance
AF noisy and slow
Sharpness: very good level at f/1.8 and f/2.8, rising to excellent from f/4 to f/8.
Sharpness is still very good at f/11 and f/16, only falling off to fair levels at f/22.
Edge sharpness is quite poor at f/1.8, fair at f/2.8 but then perks up to being very good at f/4 and excellent at f/5.6 to f/8.
It is still very good at f/11 and f/16, falling off to being only fair at f/22.
CA (Chromatic Aberration) is remarkably well controlled throughout the aperture range. It is very unlikely that CA will be seen as a problem and if further correction is ever needed we can of course look to software solutions.
Vignetting at open aperture is quite obvious at -1.5 stops, although this does have a useful side effect in that corners of an image are often darkened inpost processing to concentrate our eyes on the centre of the image.
Here we have a natural effect, more often seen in wide angle designs. At f/2.8 darkening has reduced to around two thirds of a stop and this has reduced to about one third of a stop by f/4. It doesn't really get any better than this, the mild -0.3 stop vignetting continuing right through the aperture range.
The lens shows +0.63% pincushion distortion, which again is an excellent performance. Further correction could be made in software if the need arose, but for most purposes this would not be necessary. Performance against the light is excellent as well, and flare was not observed in any of the conditions found throughout the test period.
