Today DxOMark published their test results for the Samyang 85mm f/1.4 AS IF UMC lens for Pentax mount ($269):
DxOMark’s conclusion:
“Reasonably-priced and sharp when stopped down a little, the Samyang 85mm f1.4 AS IF UMC looks like a bargain. However, its popularity will be limited by the stopped-down metering, though the viewfinder will still be reasonably bright at f/2.8 and f/4, of course. Autofocus isn’t offered either, and as it lacks any means of data exchange between the body, there’s no record of the shooting aperture, which can be disconcerting when looking back at images. Providing those shortcomings can be overlooked, there’s no real reason not to like this model. It offers great image quality at a very reasonable price.”
