All images were taken using large basic jpegs with the Standard picture control. Sharpening +6, D lighting OFF.
Samyang lenses too, despite being reluctant to return them, especially the Samyang 85/1.4.
[taken with my lovely Tamron 28-75. I love its semi macro capabilities].
There are colour coded marks on the depth of field scale, which is good for estimating the plane of focus for manual focus lenses. You focus the lens by turning the textured focusing ring near the front of the lens. I wished the ring was a bit wider though.
From this image, you can see there is some complex barrel distortion at the bottom periphery of the image. Its not perfect, but I'm not complaining about it. The lens vignettes too at maximum aperture.
Of course, we can't expect this lens to be as bokehlicious as a 50/1.8 lens for example, due to its wider focal length and slower maximum aperture.
Hmm.. I seem to be getting a hang of manual focus lenses faster than I thought I would. Hopefully a Nikon 50mm f/1.2 AI-s lens will drop down from the heavens one day ;)
