no, I meant the Linos 128DFHR and the Mejiro FEH320 (the last two data sheets linked above), sorry for being ambivalent.
from the data sheets to me it seems like they all would perform extremely well (ie. close to what is possible at F2.4 at 3.5x), I never saw any MTF curves for the rayfact, but given from what I know about their other lenses and the price, I'd be very surprised if it wouldn't keep up.
I agree there's no point in comparing the 80MS, it won't come even close.
on the 50mm Micro Symmar I'm still confused about the F2.3 Curves (and missing F2.8 curves) in their data sheet, so I have no idea how to interpret that. very unfortunate though that in real world it doesn't perform as you'd hoped.
