Yup, when used appropriately (iS-series teleconverters to extend telephotos, not wide angles) they'll work just fine. Improper combinations result in vignetting. Keep in mind that in Gary Reese's tests he noted some pincushion distortion. However I don't know whether measurable pincushion distortion equates with visible distortion.

FWIW, I've used the multi-element macro diopter lens intended for the iS-1/2 series on my Zuiko 50/1.8 and 70-150/4 and the results compare very favorably with a 50/3.5 macro. Not nearly as convenient, of course, and care to prevent flare is required.

Will the B-300 1.7x converter for the iS/L series work on my OM lenses...With no loss of speed and marginal effect on image quality?
