The Canon EF Lens to Sony E-Mount Camera Lens Turbo Adapter Mark II from Mitakon allows Canon EF lenses to be mounted on Sony E-Mount APS-C format cameras, increasing the angle of view by 0.726x and the maximum aperture of the lens by 1 f-stop.

The four optical elements of the Lens Turbo adapter condense light from the Canon EF full frame lens and project it onto the camera's APS-C sensor allowing the sensor to capture all of the lens' transmitted light, negating the 1.5x crop factor and effectively producing full-frame coverage on non-full-frame sensors. A corresponding increase in the maximum aperture of 1 f-stop makes the lens more effective in low-light situations.

The Mark II version of the Lens Turbo features an improved design to produce sharper images. Its rectangular rear lens rests closer to the camera's sensor improving light transmission and an enhanced lens coating minimizes ghosting and flare. One extra-low dispersion (ED) lens element reduces aberrations for better delineated images. The adapter offers a sturdy metal construction and stainless steel mounts, it attaches to both camera and lens with little play and includes a front and rear protective cap. The Lens Turbo is a manual adapter offering no electronic communication between lens and camera.

The Lens Turbo adapters are compatible with APS-C sized sensors. Although they will physically fit the Sony full frame mirrorless cameras, the camera must be set to Crop Mode to fully support the speed booster's functions.

    Canon EF Lens to Sony E-Mount Camera Lens Turbo Adapter Mark II is rated 3.7 out of 5 by 10.
    Rated 5 out of 5 by from Absolutely Fantastic The Good: Build quality is fantastic. Moving parts are tight and precise. Optically it is sharp as a tack. I use this EF version because it will accept adapted lenses of different Manufacturers Pentax K, M42(screw), Leica-R, Nikon and one or two others. Sometimes I use it for Macro work, and there is ZERO loss in sharpness & ZERO loss of contrast. Have I tested this on precision equipment, no, I have not. But for all other applications and when calibrating your camera with a color checker, the difference between using the adapter and not, does not appear to have any impact on the Hexadecimal color values in Photoshop. There are no electronic contacts in this adapter, which for me is not a concern as all of my lenses are manual. The rear optic is cut to the shape of the sensor well of the NEX & other Sony E-Mount 1.5x Crop sensor cameras. The rear optic protrudes and is mounted into the body and there is a rotating mount ring that locks the adapter onto the body, which obscures the lens release button on the body because the adapter uses pressure to stay on the body. Initially I used a piece of tape over a portion of the release ring because theres no indent on it to lock it into place, however the pressure is sufficient to hold it on, even after weeks of use and or in situations where your gear is vibrated. A thick elastic band will do the same. A rear cap when the adapter is not in use is essential as the rear optic protrudes beyond the mount and flange. I particularly like the OP/Tech heavy duty ones with the rubber O-ring. I never touched the rear of the lens until today, and the optic hood what I'd thought was metal, is in fact rubber, so it will not scratch your sensor even if you did manage to make contact. The bad: The bad is that in direct sunlight (ie: shooting into the sun where the sun is in the middle top or bottom of the frame), you will get a mild reflection off the reduction optic in the center of the image which will be a feint mix of Indigo/ Orange. You could see it as lens flare but its mushy and feint. A lens hood will reduce this. The Lens Release knob on the EF side, is functional and sturdy but clunky and in my case, crooked. There is some variation in the reduction between the various manufacturers for patent reasons. This is a 0.72x, others are variations on that. Metabones make their Speedbooster alternative using Patented Calwell optics and have proprietary optical enhancements to prevent vignetting and electronic components and this ultimately brings the price tag up to seven hundred dollars at the time of writing. This Mitakon Zhyonghi Lens Turbo II is amicable and presents extremely good value for money while being a solid performer and not much of a compromise on the Metabones Speedbooster.

    Rated 3 out of 5 by from OK for all the lens from f/2.5, bad for f/1.4 1.2. I tested many of this one, and this is an OK product. If you plan to shoot from f/2.0 2.5 2.8 This Adapter is sharp. 1.2 1.4 1.8 ---> only the metabones more than $600 can help you. So, get this one if your lens is not too wide. For budget, I will buy this one, since I have 90mm f/2.5 and 90mm f/2.8 or 135mm f2.5 2.8.. With 135mm f/2, this one perform good too. Just NOT for 85mm 1.4 or 50mm 1.2 lens.

    Rated 4 out of 5 by from Doesn't work with FS5 and FS7 Please be aware, it doesn't work with Sony FS5 and FS7. Also if try to put adapter on these cameras, you can scratch the glass of the sensor and the back glass of the adapter. Works fine on Sony A6500 though (and I guess all other Sony mirrorless cameras.)

    Rated 3 out of 5 by from Convert your cropper to full-frame, but rather soft wide ope Use my EF lenses on an A3000. Nice that I have a $ full-frame camera with this converter, but it is quite soft wide open with just about every lense tested. So you have to stop down, and by that point the F stop of light that Mitakon claims to give you has been lost. Compared to the EF lenses mounted on a bona fide Canon FF camera, this adapter on a cropper SONY body of course cannot compare. But it is a great way to get into the mirrorless game for cheap if you come from a Canon system.One thing I really don't like is how the adapter mounts to the body with a twist around action. I'd much prefer the lock that you get with regular lense mounts; don't know why they made it this way.I've no experience with the much higher price metabones, but apparently it's supposed to be the cat's meow. This is fun for experimentation though. I wouldn't advise it for professional work though, but then again, most people wouldn't be taking a $ plastic camera to pro jobs.

    Rated 4 out of 5 by from Works great, locking mechanism not great Very happy with the images that is creates, although the locking mechanism to the ef mount is sticky and the lock to the e-mount is not reassuring, a weird twisting lock that does not feel tight and is not easy to do on the go.

    Rated 4 out of 5 by from Sorry but it doesn't fit. I was hoping it would fit on my FS7. But it does not. It works on a A7 in 35 mode. So I need to look around for an other solution and try to sell this one in the meantime.

    Rated 4 out of 5 by from Great, but doesn't fit all M42 glass While the vast majority of my lenses work, my venerable Takumar 50mm 1.4 does not mate with this adapter properly. For this lens, there are issues with focusing out to infinity and aperture ring binding. That issue aside, if you're interested in shooting full-frame on your vintage manual lenses, this is a great product.
