This is a Rokinon Automatic MC 28mm f/2.8 lens for Pentax M42 screw mount camera bodies.
I am using it on my Canon 40D EOS through a M42 to EOS adapter.
Aperture Priority Mode
Wired Shutter Release
$10 SGD Note >.<
No post processing done other than the cropping and stitching as shown.
Like most lenses in the market, the image is soft when the aperture is wide email@example.com and the quality turns out better after 1 to 2 stops down as seen in the image.
This lens proved to be useful and would be able to produce excellent macro images if coupled with some image sharpening and noise reduction.
