Latest Review Posted | promaster 24mm F2.8 This lens is well-received and is the house brand of a chain. It is same lens as the Ozunon by Ozone Optical. It was also sold under a number of brands, ie. Ensinor, Clubman.
I picked up a pristine copy with Minolta SR mount. I expected similarly great results, but discovered my sample is de-centered.
A soft focus spot to the right side. I wasn't able to get rid of it entirely by stopping down.
It had affected the center sharpness as well.
It appears these 3rd party brands suffer from quality control. There is no signs of abuse to my copy.
Re-collimation may relieve the ailment.
Meanwhile the review reflects my bad copy. |
