Hi guys the Samyang 14mm F2.8 ED AS UMC turned up and WOW what great lens it is, great build quality, solid smooth focusing, plenty of metal and fairly compact. Full communication for aperture and focal length in the Nikon mount..
Sharpness? Straight out of the box and on the camera focus to infinity and......horrible, soft center and....arrrgh the edges!
But we know that Samyang hardly bother with infinity calibration, ( which seems strange they must get loads of returns).
First port of call, is it well centered? OMG it is!
Infinity focus was 2.9 mts on the distance scale, I calibrated infinity fully open at one third from the frames edge instead of the center using LV, as there is a little field of curvature, this gives a compromise and the results are good sharpness across the frame into the corners. there's a little blooming around super high contrast areas like bright white boats against trees and bushes, frankly it's of little consequence, that's gone by F4 and every thing's tack sharp everywhere. Chromatic aberration i don't see it's auto removed. There is a tiny bit of flare with the sun in the frame. Distortion is it's biggest flaw...Bof!
For 315 euros delivered it's "truly" a lens not to miss, especially in the Pentax and Nikon mount that carry the contacts.I love Samyang lenses.
Another birdie lens.....you've guessed it ; .....it goes cheap cheap cheap! Five stars.
PS. It's the period of the Perseids shooting stars, I'll give it shot tonight.
