Re: Lens adapters

I believe the Nikon "E" lenses lack the aperture lever needed to mechanically control aperture, so an adapter with manual aperture control has nothing on the lens to connect with. Aperture control is via electrical contacts on these lenses.

Re: Lens adapters

I believe you are thinking of Nikon "G" Autofocus lenses. Nikon G lenses have no aperture ring, and aperture control is through electronic contacts. Nikon-G to MFT adapters manipulate the aperture lever on the back of the lens - which allows control of the aperture by movement of this internal aperture lever with an aperture ring that exists on the adapter barrel.

All Nikon Series E Lenses are vintage manual focus lenses that have aperture rings. They are good lenses that will work reliably on the LS300. No special adapters are needed for "E" lenses, just basic Nikon to MFT.

Re: Lens adapters

Actually, I was referring to the new Nikon E type lenses which require electrical communication between the body and lens for aperture control.

Re: Lens adapters

Luke is correct, the newest Nikon E and Tamron G2 lenses lack manual aperture levers and are incompatible with all manual Nikon-to-MFT adapters and speedboosters. While Nikon G lenses have electronic contacts, their iris ring is operated by a mechanical aperture lever, which makes them compatible with manual Nikon-to-MFT adapters and speedboosters.
