<b>Meike 85mm f/1.8 Performance</b></br> Sharpness: very good level at f/1.8 and f/2.8, rising to excellent from f/4 to f/8. </br>Sharpness is still very good at f/11 and f/16, only falling off to fair levels at f/22.</br>Edge sharpness is quite poor at f/1.8, fair at f/2.8 but then perks up to being </br>very good at f/4 and excellent at f/5.6 to f/8. It is still very good at f/11 and </br>f/16, falling off to being only fair at f/22.</br>CA (Chromatic Aberration) is remarkably well controlled throughout the </br>aperture range. It is very unlikely that CA will be seen as a problem and if </br>further correction is ever needed we can of course look to software solutions.</br>Vignetting at open aperture is quite obvious at -1.5 stops, although this does </br>have a useful side effect in that corners of an image are often darkened in</br> post processing to concentrate our eyes on the centre of the image. </br>Here we have a natural effect, more often seen in wide angle designs. At </br>f/2.8 darkening has reduced to around two thirds of a stop and this has </br>reduced to about one third of a stop by f/4. It doesn't really get any better </br>than this, the mild -0.3 stop vignetting continuing right through the </br>aperture range.</br>The lens shows +0.63% pincushion distortion, which again is an excellent </br>performance. Further correction could be made in software if the need </br>arose, but for most purposes this would not be necessary.</br>Performance against the light is excellent as well, and flare was not observed </br>in any of the conditions found throughout the test period.</br></br><b>Meike 85mm f/1.8 Pros</b></br> Excellent sharpness</br>Low CA</br>Low distortion</br></br><b>Meike 85mm f/1.8 Cons</b></br>AF noisy and slow</br>No weather resistance</br> Edge softness wide open</br></br><b>Package:</b></br>1*MK-85MM F/1.8 Lens</br>2*Lens Cap(front and rear)</br>1*Lens hood</br>1*Lens bag</br>1*Lens Cleaning Cloth</br>1*Manual and Warranty Card</br>
