Hi Kumar, I was wondering about you!
I bought a 300 Q from you and took a shot of the same subject, at the same exposure with it and its multicoated brother, the M.
I cut the 8x10 negative on the part of the scene I wanted to enlarge, into a 4x5 size neg and then enlarged it to an 11x14 size.
I couldn't find a difference between them. Nne et all!
I then sold the M at a good profit and never looked back.
The lens fits in the pocket of my T-shirt and I always carry it when on the field, you should not have a problem selling this beauty.
Hope all is well over there.
