TTArtisan Releases 6-bit M-Z Adapter for Greater Functionality of Non-Native Lenses

By Molly Kate

With the new launch of the TTArtisan 6-bit M-Z adapter, Nikon mirrorless users can now engage capabilities such as EXIF recording, semi-AF, and stabilisation with M-mount lenses. Previously, most adapters limited focus to manual only and could not engage with functions such as recording metadata of the lens or anti-shake technology.

TTArtisan 6-bit adapters are changing this by allowing the Z mount camera bodies to connect with the M mount lens electronically. They record EXIF data, support trap focus and the focus indicator function, and allow features like stabilisation to be used. Lenses without the 6-bit coding can still be used but the focal length has to be set manually on the adapter for the camera to record the data. This is done by using the “click” focal length dial which makes it easier to avoid changing the dial by mistake when shooting.

The adapters allow information such as exposure time, aperture, focal length, and ISO to be recorded. Two focus capabilities can be used, trap focus and the focus indicator function. Trap focus is when the camera automatically takes a photo when the intended subject appears in a pre-set focus area. The focus indicator function is also supported by the adapter where the camera readout on the LCD screen tells photographers where the focus plane is relative to the subject. This requires the camera to have the focus indicator function already built in.

So what is 6-bit and why the m-mount? Back in 2006, Leica announced that future M-mount lenses would be made with the 6-bit coding for connection to its digital camera line-up. The 6-bit coding is a set of small rectangular fields placed in a row on the bayonet ring of the lens. Each field is marked as black or white. Together this creates a binary code (can be from number 1 to 64) that identifies the lens placed on the camera. The digital cameras can then read this code and record the EXIF data of the lens along with increasing image quality by taking full advantage of the camera processor as said in the original Leica press release.

TTArtisan’s 6-bit M-Z adapter is constructed of aviation aluminium which makes it durable yet lightweight. The adapter weighs around 56g. Added to the inner wall is an extinction thread which is meant to suppress any stray light to avoid flares or leaks. The height is only 17mm which is relatively slim and great for photographers that don’t like bulky adapters. Lastly, there is a button on the adapter that easily allows the settings to be reset and re-recorded if the lens has been changed.

Does this mean the adapter is mechanically coupled to the rangefinder cam in the lens? That would be extremely cool if so. Any plans to bring this to Fuji X mount?

Very interesting. I hope they will introduce adapters for other lens mounts.
