Perfect adapter for mounting my Sigma 18-35mm lens to my MFT Gh5!

I use this on my Blackmagic Pocket Cinema Camera to get the super 35 look and feel. It’s been really awesome, no complaints. The build quality is top notch and it’s definitely heavier than I thought it would be. I can also use all the glass I already own which is a huge plus. Would definitely recommend!

Yup, it's awesome. I use it on my LS300 and it's pretty much like magic. These guys at Metabones really know what they are doing. I've never purchased any thing that I wasn't thoroughly impressed with. The fit is perfect and snug, and really increases the quality of my images. Overall, very happy. A++++

Perfect compliment to the Sigma 18-35 for use on the GH5

First of all, the F-mount has no communication with the lens. That means no AF or functional metering for my GH5. Not a deal breaker, but it would be nice if MB was a little more clear about the compatibility difference between EF and F mount converters. Also, not a tight fit on the camera side. Still a little rotating slop. All that said, would still buy it again. Image quality is great.

Using with PEN-F and Nikon AI and NonAI lenses like the 35mm f/1.4 (which turns into a 25mm f/1.0) and the amazing 85mm f/2 (60mm f/1.4). Also works great with 180mm f/2.8 (127mm f/2). This is in my B&W and bokeh kit.

I got this to use 1980's vintage Nikon lenses on an Olympus Pen F. Optically it works well. I prefer manual focus and the Pen F has a good focus peaking function. It seems that some purchasers misunderstand the purpose and cost of this adapter. The optics better match the lens focal length and coverage to the smaller sensor. A favorite lens of mine is the Nikkor 50mm F1.2. With this adapter, it becomes equivalent to a 71mm rather than 100mm lens, at F0.85! An interesting benefit is that it also improves the resolution of most lenses. The only downside is that it is entirely manual. That really isn't that much of a downside. The only thing that personally bothers me is that mine is a very tight fit on the body. I ended up buying another body for my awesome Voigtlander lenses so I can leave the adapter on full time. That's how much I like it!

Industry's best aperture ring covers a 8-stop range, clearly indicating actual number of f-stops. No more guesswork! (Patent pending)
Compatible to both Nikkor G lens & F lens (include non-AI & AI lens mounts)
Increase maximum aperture by 1 stop
Increase MTF
Makes lens 0.71x wider
Patented 5-element/4-group optical design incorporating ultra-high index tanatalum-based optical glass by Caldwell Photographic in the USA
The tripod foot is detachable and compatible with Arca Swiss, Markins, Photo Clam ball heads
Always Enhance and Never Degrade the Performance of the Attached Master Lens
Like the ULTRA series for Sony E-mount, the new Speed Booster ULTRA m43 uses an advanced 5-element 4-group optical design incorporating ultra-high index tantalum-based optical glass. However, the new design is specifically optimized for the Micro Four Thirds sensor and filter stack and as a result achieves an astonishing level of performance that sets a new standard for focal reducers.
Like the revolutionary original Metabones Speed Booster announced in January 2013, the Speed Booster ULTRA m43 has a magnification of 0.71x and so it effectively reduces the crop factor of mirrorless Micro Four Thirds mount cameras from 2.0x to 1.4x. However, the new ULTRA design makes very effective use of exotic materials at the furthest limit of glassmaking technology and as a result is almost perfectly corrected for use with all fullframe SLR lenses regardless of aperture. The Speed Booster ULTRA m43 will also work extremely well with many DX and APS-C format lenses provided the image circle of the lens is large enough. Optical performance of the new Speed Boosters is so good that the MTF of any lens attached to it will be improved. Even the latest generation of ultra-high performance SLR lenses such as the Zeiss Otus series can be improved by adding a Speed Booster ULTRA m43.

Why Metabones
Since its inception, Metabones has been designing and manufacturing lens adapters recognized among professionals and enthusiasts as leaders in design and workmanship.
Contrary to the popular trend of other factories using an aluminum ring painted black on the camera-body-side, they instead take no short-cut but use precision-machined brass with chromium plating on both the camera-body and the lens sides of their adapters, in order to ensure smooth mounting, great appearance and durability. The lens side of the adapter features a strong leaf-spring structure, strengthening the adapter-lens connection and ensuring tightness of the lens in order to reduce wear and prevent focus errors and optical alignment issues from appearing. Metabones uses matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens.
All Metabones Adapters follow this tradition of uncompromising precision, robust build quality and outstanding finish. Metabones new Smart Adapter series of products add industry-leading electronic interfacing technology from Canada, with true electronic control of the lens' aperture directly from the camera body.
Both camera-side and lens-side of the adapter are made of brass, precision-machined and plated with chromium
Satin surface finish - just like your OEM lens and camera mounts
Precise fit and solid connection - lens has no play, gap or wiggling when mounted on adapter and no adjustments are required to fit your lens
Designed to reach infinity focus while maintaining the correct registration distance required to maintain optical quality of CRC lenses or lenses with floating elements
Metabones Smart Adapter series adapters have the following additional features
True electronic integration of aperture diaphragm - let camera automatically choose aperture in P or S exposure modes or dial in yourself on the camera body in A or M modes
EXIF data such as lens identification, focal length and aperture
