me too, but the other issue i face is with helios 44M av has gone haywire there, guess have use a foil or junk it
Explain. What do you mean by haywire? If you mean that the metering is not linear, that is sort of expected and may be the case with any non-A lens in Av mode.

like the shutter speed is reading 2000+ when the ideal ought to be 125, clicks but underexposed., i do have color ultron 50 1.8 M42 which does not cause this problem

I've noticed that my SMC Takumar 135 doesn't touch any of the pins on he mount; they're all completely exposed with the lens mounted. I have to wonder if that has something to do with it. I'm pretty sure my M50 covers them all - and stop-down metering works a treat with that.

... Then again, stop-down metering doesn't work with my Tokina big zoom thing, which attaches via an adaptor, which I think covers all the pins ... But perhaps isn't conductive.

Oh I don't know ;-) Av mode or Sunny16; that'll do.
