Sigma 60mm f2.8 DN on Older Olympus bodies

Is anybody using the Sigma 60mm f2.8 on older Olympus bodies like the E-P1, E-P2 or E-PL1? I have been considering picking one up, but this note from Lens Rentals give me pause:

"Please Note. We’ve had reports that some of the first generation Micro 4/3 cameras have issues with the Sigma DN lenses. We haven’t tested this ourselves, so we can’t confirm how widespread this is. With that said, you may want to think twice about using with early cameras like the E-P1 & E-PL1."

Has anyone using this lens on the older bodies had any issues? If so, what are they? Thanks.

 

Thanks. I have no issue with renting, however, with such an inexpensive lens it hardly makes sense to me seeing as a 4-day rental would be more than 20% of the cost of the lens. I'd probably rather just purchase it, and sell it if it didn't work out (it would probably cost me the same and I'd get to use it a little longer), but I was hoping some users here might have some experience.

 

I have not, but as the OP I'll provide an update that I have purchased the lens and can confirm it works fine on an E-PL1 (although I'm sure the AF is faster on newer bodies)
