Difference in Lens Adapter Question

[swandy]

I have the EP2 with both the original Olympus OM - 4/3 adapter and the Olympus 4/3 - m4/3 adapter. I have been using this combination with a Lensbaby Composer and a few old Olympus OM Zuiko lenses.

Does anybody know if there an advantage - either image quality, exposure, sharpness, focusing distance, etc. - to use the Olympus OM - m4/3 adapter? (Aside from having to use one adapter vs. two.)

Thanks,
Steve

Aside from an increase in size/weight, no.

Steve, They will both fill the same air.

Thanks guys. That is what I figured, but just wanted some confirmation. I had read elsewhere that by using the original OM adapter with the 4/3 adapter, you are effecting the close focusing distance of the older lens. Thought that someone who had both could confirm or deny that.

That is a true statement. IQ is not affected by having two adapters but they work as an extension tube, so it will affect the minimum distance you can obtain focus from.

The question - at least my question - is do the combination of the two adapters effect the lens performance/focusing distance any differently than just using the single OM - m4/3 adapter. I would assume that it shouldn't, but wanted confirmation perhaps by someone who has tested (or read about) both alternatives.

as with any decnet adaptor (system) you'll loose almost nothing on the close focus, but the tolerance of manufacture may be a little off around infinity. This is where 0.05mm will make a difference.

unless I've misunderstood your question
