We like the Olympus 12-45mm F4 and 12-100mm F4 for enthusiasts. The former is a good option if you like to work with a smaller kit, while the latter is the zoom to get if you want more zoom power without changing lenses. The Panasonic Leica 12-60mm F2.8-4.0 is another good mid-priced zoom. 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 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. 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. 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.

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.

Our low-impact designs offer professional quality at an affordable price. Urth Micro 4/3 lens mount adapters allow you to use ... Wide-angle lenses capture an epic, broad view of the world and are ideal for landscapes and architectural imaging. MTF data is a full diffraction-based calculation that assumes the Speed Booster ULTRA m43 is attached to a perfect master lens having an exit pupil distance of 100mm. Note that the MTF calculations do not take into account sensor-induced apodization effects, sometimes called “pixel vignetting” or “pixel shading”, so actual results at large apertures are likely to be better than the calculations indicate.Figure 7: Measured MTF of a 55mm Zeiss Otus without (left) and with (right) Speed Booster ULTRA m43 at f/1.4 and f/1.0, respectively at 10 lp/mm and 30 lp/mm. 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. First up is the focal length. The millimeter number of every lens is relative to its angle of view, and lenses with a smaller number capture a larger view.

Sony optimized their e-lenses to be used on e-mounts disregarding compatibility with any other mount. as the e-mount has the shortest flange focal distance, this made sony e-mount lenses incompatible with any other mount. 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. As such, expect to see lenses with smaller focal lengths than you might expect. A 12mm focal length on a full-frame system is ultra-wide, for instance, but captures a wide standard view on an M43 camera. That's about the same as the main lens on your smartphone or a 24mm lens on a full-frame camera. The rule of thumb is to double Micro Four Thirds focal lengths to directly compare them with full-frame. Finding a lens for a Micro Four Thirds camera isn't hard—there have been hundreds of different types over the years. But there are some things to take into account.Had they designed the lens for NEX first, they would have to redesign all the elements to make it compatible with MFT. 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.
