Welcome to Leitax. This is our Leica-Sony/Minolta page. I would like to thank all the Sony users that requested this mount and were waiting patiently for it. Finally, we can offer this new replacement Leitax bayonet to use two cams, three cams, R-cam and ROM Leica-R lenses on Sony or Minolta bodies.
-This conversion is fully reversible and will not damage either the lens or the camera.
-This replacement mount is ready to install the appropriate chip on it. Which is needed for some of the modern Sony cameras to operate. With the proper chip, our Sony camera will display the focus confirmation light, will meter in A mode and will enable the Super Steady Shot.
-The Leica-R lenses will focus to infinity and will maintain the aperture click stops. After checking many models produced for several decades in three countries, we found differences at the point they focus to infinity, so our bayonet is measured to focus to infinity with all of them. Thus, maybe some units will reach even beyond infinity, in this case turning back the focusing ring just half millimeter is enough.
-For metering, I use the stop-down method in A mode, to have an accurate metering, remember to set the widest aperture on the Sony camera.
Some of the instructions you see on the left are for the Leica-Pentax bayonet. Just change the final step, installing the Leica for Sony bayonet instead and you are ready to shoot with your Sony camera.
The following lenses
can use the Leica-Sony bayonet only after irreversible surgery, due to
physical incompatibility : |
- To have the Super Steady Shot system working properly, you'd have to order the correct chip for the lens you are going to use, with the max. aperture and focal length of your Leica lens recorded in it.
- I recommend the
more advanced chip (the thinner model -M42C) from James
Lao,
if you want me to glue the chip in your bayonet before shipping it,
please add "Leitax" in the text box when ordering in his web shop and
he will send your chip to me.
Or you can find him in Ebay ( james_dn )
- To glue yourself the electronic chip, just support it to the left or to the right in the precisely machined slot on our Leitax Leica-Sony bayonet, depending of the chip model (take a look at the pictures below).
- The Leitax bayonet also accepts simpler chip models that you can find in Ebay.
- I'm offering now a
reversible
custom conversion work for the Leica Zoom lenses with ROM
contacts that are, in general, not suitable for direct
bayonet replacement, please contact me for an estimate.
Of course, there is no problem with 3-cam Zoom lenses to use the
standard Leitax mount.
- It is possible to install the Leitax bayonet on the Vario-Apo-Elmarit 70-180/2.8 ROM, as this lens is build the same way as the Leica ROM primes.
- CAUTION! The rear element protective shroud on the 1st type 50mm Summicron needs to be sanded down to clear the some internal metal part around the mirror of the A900 camera.
-
I've discovered that my A350 can take pictures without the chip. In
Manual mode, just turn the control wheel to set the speed and you will
see the scale in the viewfinder showing the current exposure value.
In
Manual mode, the camera will take the picture and will save it in the
memory card. If you have a different camera model and can try it,
please tell me if it works too.
But we don't have focus confirmation and the anti-shake works correct
only for the 50mm default value.
- We can use the
telephoto lenses Telyt 400 and 560/6.8 on Sony cameras with a special
Leitax bayonet.
But lenses newer than head number 2380541 can have different cams that
will not be compatible with the Leitax mount. Please check your lens,
has it the same cam as in the instructions pictures?
- New! I can machine a special bayonet for the Apo-Summicron 180/2, to avoid removing its black internal tube.
- New! Confirmed: the Summilux 35/1.4 doesn't hit the mirror of the A900/A850 cameras.
- You can see pictures taken with Leica-R lenses with modern digital cameras at the Leitax group at Flickr.
Now you
can order the Leica-Sony bayonet here.
Please check how many screws has the Leica original bayonet of your
lens to order the appropriate replacement.
- The registered mail service is reliable but the delivery time is not very fast or even regular. If you need the Leitax mounts fast or you have a deadline I'd recommend the courier option.
---- We are
now offering three variants of the Leica-Sony bayonet:
1--- The
normal variant with Full
and Half stops at the
aperture ring, just like the
original Leica-R lenses are.
2--- The
special variant with
only Full stops. With
it, you can compose the picture in
the viewfinder and take all the pictures you like changing the
diaphragm value many times and still knowing the value of the aperture
ring, just counting the "clicks". You don't have to remove
your eye from the viewfinder to check the diaphragm value.
As an additional
benefit, you can use 1/3 diaphragm values.
3-- The
special variant with no
F-stops. This one is
intended for the film makers, who
need a silent aperture ring operation. Usually they remove the small
ball to avoid the "clicks", but this is not good, there is a danger to
destroy its spring and also this creates a new problem: the iris spring
can move the aperture ring if there is nothing keeping it in place.
