Iv'e had two capies of the Sammy 14 (one in Canon mount and one in SonyE) and one of the 351.4; and in both cases the focussing scale was MEANINGLESS. Massively out of calibration.
I think I see how to calibrate the 14, but I haven't bothered. But if you are really set on hyperlocal calculations then you'll have to. You can set up targets at various distances to the film plane. I imagine (but am not sure) that the *relative* distances are right, once you have infinity calibrated. Though I'm not at all sure - my impression with the 14 was that the error was different at different distances.
Optically great lenses though, the hassle is well worth it at the price. I sold my canon 14II for two grand, bought the sammy and pocketed $1700. With a distortion profile for when it matters the Sammy is easily as good.
Thing about hyperfocal work, though, is that there is a trade off between getting infinity and some nearby point sort-of-sharp, and getting the thing that really care about tack sharp. I reckon just focus the thing in the EVF.
