Meike 85mm f1.8 Large Aperture Full Frame Auto Focus Telephoto Lens for Canon EOS EF Mount Digital SLR Camera Compatible with APS C Bodies Such as 1D 5D3 5D4 6D 7D 70D 550D 80D

Meike 85mm f/1.8 Performance AF noisy and slow Works with : Canon EOS EF mount cameras, such as 1D 5D 5D3 5D4 7D Mark II 70D 80D 800D 1000D 1100D 600D 60D 450D 550D Rebel T7i T6i T6s T6 T5i T5 T4i T3i SL2 Digital SLR Camera etc 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. Yeah, compatible with M50, but when you change the lens, first install the original Canon lens on the camera, take off the camera when the lens is rotated out (the lens lock is opened), and then replace the adapter ring and the Meike 85mm f/1.8 ef lens. It means that you need to use the original Canon lens to unlock, turn off the machine directly after unlocking, and then install the adapter ring and the Meike 85mm f1.8 EF lens. 85mm can be used on portraits, macro and even landscapes.
