The Urth online gallery ( Gallery) is an online space where artists ( Artists) offer for sale artworks ( Works) to collectors, users and members of the public ( you). The following table lists lenses which has been tested. Other lenses not listed here typically works well, too. Accurate 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 Micro Four Thirds system is especially appealing for photographers who use telephoto lenses. These types have longer focal lengths, so they capture a narrower angle. They're ideal for photographing skittish wildlife, and for getting great shots of team sports from the sidelines or stands.

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 have come from m43 Markus. Ignore the Voigtlander example. Why? Because Voigtlander, similar to Samyang etc etc, perhaps when they sell an m43 lens, it can be the same glass as they sell in full frame for Sony - it just the mount that is different, and the focus of the rear lens element.

I am not disappointed I can't use E mount lenses on M4/3, Even my Nikon AIS lenses are hard to figure as being better fits than most of the tiny and fast lenses made for the format. But on E mount Micro Four Thirds cameras first went on sale in 2008. At the time, the mirrorless concept was novel. Instead of using an optical viewfinder and mirror, like the Four Thirds SLR system that preceded it, M43 takes the view from the image sensor and sends it right to an electronic display. The 55mm f/1.4 Zeiss Otus is widely recognized as perhaps the finest large aperture photographic lens ever produced, and yet the Speed Booster ULTRA m43 transforms it into a 39mm f/1.0 lens with even higher MTF. In fact, the resulting combination is likely the highest-performing f/1.0-class photographic lens available to the public. Third party lens manufacturers will try to optimize the design of a particular focal length lens to suit as many mounts as possible with the least amount of adjustments. If you want a wide lens that gathers more light, you need to look at fixed-focal length choices. Most wide primes for the system are manual focus. Samyang and Venus Laowa aren't household names but cover a space where OM System and Panasonic don't play.

In an ideal world, we wouldn’t have to adapt lenses from other systems. But even when lenses are plentiful, it still happens. When Canon first started introducing video to their DSLRs, many video shooters were using adapters to mount Nikon and M42 lenses onto Canon bodies. And quite a few still do that to this day. So, it’s not a new concept that’s come with mirrorless systems. You do need to make sure you're getting the right type of lens for your camera. In this guide, we cover lenses for the Micro Four Thirds system. It's the oldest modern mirrorless system and one that multiple camera and lens makers support. The Sigma Art lenses, 19mm, 30mm and 60mm. All good, 30mm and 60mm excellent. I have the 19mm and 30mm for E mount, and the 60mm for M4/3. Why, well the crop factor math is just more useful for the 19mm and 30mm on APSc Sony E mount, I have 17mm f1.8 very much better. But the 60mm is like a 120mm on M4/3 just right for many shoots, and I have the 45mm f1.8 which is a 90mm portrait length.Only one Micro Four Thirds adapter features in this comparison. But it comes with a big benefit. The Metabones Speedbooster offers the field of view of a full frame lens resized to fit a micro four thirds sensor. This scaling down of the lens’s image projection circle basically intensifies the brightness, so wide open at f/1.4 it’s brighter than a native Micro Four Thirds lens at f/1.4. 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. 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. Lens Compatibility: Any full-frame (36 mm x 24 mm format) SLR lens with the appropriate mount can be used. DX format lenses can be mounted but may result in vignetting when the full Micro Four Thirds format is used, depending on the lens. DX lenses are fully supported when used on the Panasonic GH4 in Cinema 4k mode, and will function without abnormal vignetting. Canon EF-S lenses are not supported, but third-party EF-mount APS-C lenses can be mounted and will have full electronic functionality. This Fotodiox lens mount adapter is made with high standard precision. Its all metal design and polished surface is designed to guarantee smooth mounting and long lasting experiences. This adapter allows Micro Four Thirds (Micro-4/3, MFT) Lenses to fit on a Sony Alpha E-Mount system camera body.

The 7.5mm UMC fisheye is a pure MFT lens and a very good one. Not expert on the rest but a lot are just remounts, as you say.

Product Specification

The flange distance is basically the distance a native mount lens is designed to sit away from the sensor. For DSLRs this is generally around the 40mm and for mirrorless cameras this is generally around 20mm (of course it varies between particular mounts). Panasonic continues to support M43 under its Lumix imprint, even though it's added a full-frame camera system to its catalog. It uses the Lumix G designation for its Micro Four Thirds cameras, which include mainstream models and specialty options like the tiny BGH1 video camera. This adapter will not work with electronically-controlled MFT lenses. This adapter is designed for third-party manual focus lenses such as Rokinon lenses. The new Speed Booster XL 0.64x reduces the full-frame crop factor of the Panasonic GH4 from 2.0x to 1.28x, thus effectively transforming these cameras into APS-H format. When the GH4 is used in Cinema 4k video mode the horizontal full frame crop factor is reduced from 2.34x to 1.50x, thus effectively transforming the GH4 into a super-35 format 4k cine camera. In addition, the speed of any attached lens is increased by 11/3 stops, with a maximum output aperture of f/0.80 when an f/1.2 lens is used. For example, a 50mm f/1.2 becomes a 32mm f/0.80, which is the fastest aperture available for full size Micro Four Thirds format. Tips: Before mounting your lens to the adaptor, please make sure that the f-stop of aperture ring on the adaptor is turned to "7" (i.e. mounting your lens to the adaptor while only the aperture ring in the adaptor is full closed.).

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.
