Hello All,

Can anyone please advice me on a lens I am thinking of buying on mail order?

It is a Schneider Symmar-S 150 f5.6 (serial no. 12671323). What is the approx. age of this lens and is it single or MC? Any comments on sharpness and will I h ave room for movements on 5x4?

The lens has a few particles of dust in one of the elements. Will this affect p erformance.

Thank you in advance for your help.
