Hoping someone can answer a few questions on the lens system for this camera.

First, the mount is Micro 3/4 (M43) and the imager is full 35. When using lenses that were designed for a 35mm SLR with a lens adapter, on this camera, there is a crop factor. What would the coverage of a 50mm lens convert to, for instance?

These $100 lens adapters (not Metabones brand) that claim to offer an increase in F stop (speed boost) and prevent the cropping... are they effective and is there a loss of resolution when using them?

Thanks much!

UPDATE: Appears the conversion is about 1.5 so a 50mm effectively covers like a 75mm and so forth. Does that make sense?

A 1.5 crop factor is what I experience. I have no experience with mount adapters with optics, but the Metabones T Smart EF/EF-S adapter gets good reviews if you have canon lenses.

Thanks Luke.
