Well, all I can offer is that I owned one for a brief period of time, and it had a terrible rear curtain lag, making uneven exposures (overexposures) across the negative. I guess it just needed a cla, but my russian 35mm zenit has recently developed the same problem, while my german and japanese cameras of similar ages have never given me any trouble at all. You are right about the lenses. They have a very cool look that only old single coated lenses can give. Its not bad by any means. I'd honestly say it is just different from the tack sharp precision of say a t* zeiss lens.
