Regular readers of the
LEICA Barnack Berek blog are aware that for each April 1 we have posted a spoof
about new developments in the Leica world.
Yes, yesterday’s article about the new Leica TP was one of them.
In 2014 we reported about
a new Leica model, the Leica M-AF, an autofocus version of the Leica M. The idea presented was an autofocus mechanism
as part of the camera. The idea was that
it would offer autofocus with any Leica M lens and other lenses, like the Leica
R lenses with an adapter.
Leica M-AF with lens adapter R and 70 to 180mm f/2.8 Elmarit-R at closest focusing distance
The idea appeared to be
quite feasible and many readers allowed themselves to be taken in by the idea,
not realizing the April 1 date of the article.
I am not saying that the idea presented in the article was the impetus
for something like this to turn into
reality, but just a short while ago we were presented with an autofocus system for
Leica M lenses that utilizes that very principle.
PetaPixel reported: The Guangzhou, China-based
company Techart officially unveiled the Techart PRO AF adapter, the world’s
first autofocus adapter for manual focus lenses. The adapter actually lets you autofocus with
lenses that don’t have that ability.
This adapter is for mounting Leica M-mount lenses on Sony E-mount
cameras. Using the electronic contacts and phase-detection focusing system of
the Sony camera, the adapter moves the lens closer and farther from the sensor
plane by extending and retracting. By changing this distance by a maximum of
4.5mm, the adapter can automatically focus the lens.
In addition to using Leica
M lenses, photographers can also use adapters to connect lenses from other
mounts, like Leica R lenses, to also use the autofocus functionality. The
adapter supports both single and continuous autofocus modes, and it can also be
used to reduce the minimum focusing distance of lenses.
If this sounds exactly
like what I described in the April 1. 2014 article, it is. Looking at the basic design and its specs, it
also has the same shortcomings as described in the article.
Unfortunately, the Techart
design does not offer the possibility to be made for use on the Leica M cameras
since these do not have any electronics which would support the autofocus
system. However, I see the distinct possibility
for this adapter to be made available for the Leica T and the Leica SL
cameras. At that time, the April fools
joke from 2014 would become reality for Leica cameras other than the Leica M.
