The Fotodiox Contax G Pro Lens Adapter for Micro Four Thirds Cameras is a high quality adapter that allows you to mount a Contax G mount lens to a Micro Four Thirds camera body. It features a brass construction with a stainless steel finish as well as the ability to focus to infinity. This works with a leaf spring system for a secure attachment.

This adapter will not allow for electronic control over lens functions. In order to function with automatic metering you will need to place the camera in manual or aperture priority mode, where the camera will utilize stop-down metering to determine the appropriate shutter speed.

Q: 2. How can I get my lens off of this thing, I can't un mount my lens, what should I press?

A: There is a small silver button on the side of the adapter that you press; the button doesn't press inwards, it's more of a lever so you push it towards the camera end of the adapter (I think it goes that way, but it does not take a lot of pressure for it to release)

Q: 3. Does this adapter will work with lenses of apertures below f/2.8, like a 50mm 1.4 for example?

A: This adapter has its own iris so it does not use the lenses aperture control.

Q: 4. The picture shows some threads on the inside of the adapter. Does anyone know what size these threads are, and if they can be use to mount small filters?

A: Those are light baffles and are not threaded. They are meant to prevent stray light from bouncing around inside the adapter and causing loss of contrast.

Q: 5. I have an Olympus DE M10 Markii and Konica Hexanon 50mm f1.7 lens. I asked about an adaptor at a local camera shop and they said some people can't get some adaptors off the camera. The only review here said tight fit. That's okay, but I want to be sure I can get it off. Also, does using Konica lens produce good portraits (seeing that it is now comparable to a 100mm lens on 4/3)? Thank you for assistance. I became aware of B & H through Robin Wong videos. Do I purchase through his link?

A: the fotodiox adapter is designed to properly mount your Hexanon lens to a micro four thirds camera. It's also designed to release the lens when you're done. As with any manufactured product, quality control is rarely 100%. There are no blanket guarantees. As to it being a suitable portrait lens for your camera, it certainly is, though you'll have no auto focus and metering options will be limited. If Robin Wong has a link to the B&H website and it benefits him if you use it, then please do so.

Q: 8. what is the difference between B&H # FOPMFTANG43 $159.95 and Nikon G pro lens blue ring adapter less than $60 for Micro four third camera. will both can be deliver the same for gh4

A: The difference would be that the Excell+1 (more expensive adapter) has light focusing optics that adjust the crop factor by 0.72x, changing the original crop factor from 2x to only 1.4x. The optics also have the benefit of increasing the maximum aperture by 1 stop, taking an f/1.4 lens down to f/1.0 for example. Both would be compatible with the GH4.

Q: 9. Will this adapter work with the Olypmus OMD E-M5? I have heard of some issues with other G-4/3 adapters being obstructed by the prism on the camera and thus unusable. Are there any known issues with this?
