Fotodiox launched a new products which will make many E-mount camera owners very happy! It replaces the current hybrid metal-plastic mount ring with a full metal ring! That way you get rid of the "wiggling" you get on longer lenses. You can buy it for $39 at Amazon US (Click here).
Here is the full press text and a video which explains it:
Sony's line of E-Mount (previously called "NEX") cameras are amazingly powerful little cameras, but they have one flaw. The lens mount is a two part construction, with the critical component that holds the lens in place made of plastic. This is why any lens you attach to an E mount camera is prone to wiggling, especially longer pro lenses.
Fotodiox has created the solution - 'The TOUGH E-Mount' modification kit. Anyone can replace the original 2 piece NEX mount on their camera with an all-metal one in about five minutes. All you need is a jewelers screwdriver (phillips) to remove and replace four little screws. We've created a video to show you how easy it is:
Once you've installed the Fotodiox The TOUGH E-Mount, you can mount practically any sized pro lens on your Sony E-mount camera using one our full line of E-Mount lens adapters. With the powerful combination of our TOUGH E-Mount modification and our lens adapters, you can be confident of a solid and professional fit.Cool!
