Difference between Ricoh R1 and Rollei prego micron?

[fgianni]

I bought a Rollei prego micron off eboy, and I dlike to know if the lens is really different (better or worse) than the lens on the Ricoh R1, the lens on the rollei is branded schneider-kreuznach Curtagon HFT, but having seen both the Rollei and an R1 (unfortunately I could not take any pics with the R1 for comparison) le lens seemed identical to me, at least on a visual inspection.

Does anyone knows anything about the difference between the two lenses?

Thanks
