Fotodiox Lens Mount Adapter, Micro Four Third (MFT) Lens to Sony E-Mount NEX Camera, M4/3-NEX

Product Information

This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted. The Terms are governed by and are to be construed in accordance with the laws of the State of New South Wales, Australia without giving effect to any conflict of laws principles and you agree that the courts of the State of New South Wales, Australia will exclusively adjudicate over any dispute in relation to these Terms. If your lens does not have a manual aperture control ring, the lens aperture will revert to its default position, which depending on the lens is either stopped down to its largest f-stop or opened up to its smallest f-stop.

Autofocus is not supported with previous generation Tamron VC lenses and Contax N lenses modified to EF mount by Conurus Canada. (Newer Tamron lenses such as the 24-70/2.8 VC A007 and 70-200/2.8 VC A009 work fine.)

Product Specification

The MTF curve in Figure 3 indicates that the Speed Booster ULTRA m43 has truly phenomenal performance at f/1.0, which is the output aperture you will get when the master lens is set to f/1.4. Extremely low levels of aberration in the Speed Booster ULTRA m43 combined with the aberration-reducing tendency inherent in focal reducers means that even extremely high performing lenses such as the renowned Zeiss Otus series can actually be improved! This is illustrated in the pair of measured MTF graphs below in Figure 7.

The 'coverage' of a 4/3 lens is less than APS-C so it will not cover whole frame, nor indeed APS-C option without much loss of corner resolution and vignetting. The only possible use (maybe) for such an adapter could be to use Olympus macro lens, where angle of view, pushed very much forward to focus closely MAY allow sensor coverage. But suggest this idea be dropped. I'm about to add a Sony A7R to my gear. My current equipment is based on a Olympus OMD EM1 body with Micro Four Thirds and a few excellent Four Thirds lenses. My question is: did anyone try to adapt Olympus Zuiko lenses in Four Thirds format to the Sony A7 series? Will this work for full frame and are there any adapter recommendations? Thank you!

Urth Gallery Terms and Conditions

it should be theoretically possible to use m4/3 lenses on NEX bodies, but using NEX lenses on m4/3 is impossible. Figures 2 through 4 below show MTF at 10, 20, and 40 lp/mm as a function of image height for output apertures of f/0.9, f/1.0, and f/2.0, respectively 1. At the maximum aperture of f/0.90 (i.e., with an f/1.2 master lens) the sharpness and contrast are extraordinary across the entire image circle. At just one-third stop down to f/1.0 the performance is equal to or better than the best photographic lenses used at their optimum apertures. An additional stop down to f/2.0 yields performance that is rarely encountered in photographic optics. In practice, what all of this means is that the new Speed Boosters will always enhance and never degrade the performance of the attached master lens. That brightness increase equates to about 1 1/3rd stops. So, if you put something like a Canon 70-200mm f/2.8 lens on there, while the field of view and depth of field should match Canon, it’ll be like shooting an f/1.8 lens as far as the exposure goes allowing for faster shutter speeds and lower ISO. But, Chris didn’t feel that the performance with adapted Canon lenses was up to par on Micro Four Thirds bodies, so he didn’t do the outdoor tests they did with the Sony adapters. To test the adapters, Chris uses the Sony A7RIII, Olympus OM-D E-M1 Mark II and Panasonic G9. And the adapters are all designed to work with Nikon or Canon full frame lenses. 85mm lenses are used for each test as the shallow depth of field makes it easy to spot focus issues. Each camera is also tested with a native lens for a benchmark comparison.

Some are getting a little long in the tooth now, while there are new ones coming out that are able to take advantage of newer technology. Interchangeable lens cameras offer a lot more creative flexibility and control than smartphones and point-and-shoots. Buying a camera with swappable lenses lets you change your angle of view, and take advantage of specialty optics for macro and fish-eye shots. The Canon lenses on the Sony body all perform rather well, with the best performance coming from the Sigma 85mm f/1.4 lens used in combination with the Sigma MC-11. Chris says it feels almost like using a native lens. The worst performance came from the Nikon 85mm f/1.4 lens used with the Commlite ENF-E1. But as he says, Canon adapters have been out for a while now and have had a lot more time to tweak and develop, whereas Nikon adapters are still very much in their infancy. It doesn’t look completely useless, though. I have been prototyping such an adapter for some time (classic FT to E-mount). Theprimary motivation is to have a platform to investigate the E-mount and (M)FT mount protocols. As far as I can surmise if we ever put this into production we would only be able to sell fewer than 10 units and even that might have been overly optimistic. (I sold a grand total of 3, yes 3, of my Contax N lens to Sigma SA mount conversion service.) when they designed the 30mm f2.8 they kept in mind that they want the lens to work on both NEX and MFT, i think they designed it for MFT first, then adapted it to the NEX system, because then all they had to change is the mount type and increase the flange focal distance by 1.24mm.
