TTArtisan’s newest M-mount to E-mount adapter has a focal size dial that transmits focal size data to the digicam for lenses with no digital contacts.
As reported by DPReview, the TTArtisan ME 6-Bit adapter helps all trendy and legacy M-mount lenses and along with supporting information transmission with lenses that assist Leica’s 6-bit digital circuitry, it has the extra capability to ship pre-encoded focal lengths to a digicam physique and “faux” the digital communication.
If the hooked up lens has 6-bit digital circuitry to ship its metadata to the digicam physique, the adapter helps that transmission. For these unfamiliar, Leica’s 6-bit code system is the corporate’s methodology for offering EXIF information to a digicam, as defined by LaVidaLeica. M-Mount lenses have digital circuitry that tells the digicam its lens data utilizing a 6-bit code of ones and zeros. Relying on their association, a digicam with an optical 6-bit code reader can know what lens is hooked up.
However not all M-mount lenses assist the 6-bit circuitry, and in these instances, the TTArtisan adapter has a separate trick that enables these lenses to nonetheless permit for the transmission of EXIF information to the digicam. The adapter features a small wheel that can be utilized to pick a focal size which it then communicates to the digicam utilizing pre-encoded metadata.
This may be useful for quite a lot of causes, chief of which is that the Sony mirrorless cameras use in-body picture stabilization which is optimized for particular focal lengths. With out focal size data, the stabilization gained’t be as efficient.
To operate correctly, the focal size must be set on the adapter after it has been positioned on the lens however earlier than the whole meeting is hooked up to a digicam. On this approach, the pre-encoded focal size data might be picked up by the digicam.
From the restricted photographs that TTArtisan has supplied, it seems as if the focal size selector on the wheel tops out at 135mm. Within the demonstration video above that reveals use the adapter, 90mm, 50mm, 35mm, and 28mm settings are additionally proven.
On the time of publication, the corporate had not but supplied any further data nor had it revealed the price or anticipated availability of the adapter.
