Welcome to Leitax, this is our Zeiss/Contax for Sony page. As you know, this site is focused to give more possibilities to our film or digital cameras and, finally, with our replacement bayonet, we can use a selection of Contax lenses on our Sony/Minolta cameras. The same as with Leica lenses, this conversion is fully reversible and will not damage the lens nor the camera. The Zeiss/Contax lenses will focus to infinity, and, adding an appropriate chip to the bayonet, our cameras will give focus confirmation, will meter in Av mode (stop down), and will stabilize the Zeiss/Contax lenses. Unfortunately, the Contax lenses present a variety of different bayonets models and sizes, and the gradation of difficulty goes from easy to almost impossible. So lets start with the easy ones, the Contax MM type with narrow diameter bayonet. Please scroll down for the sales list and for the instructions As far as I know, this is the complete list of Contax MM type prime lenses we can use. MM lenses can be easily recognized as the smallest aperture on the scale is green. MM Distagon* MM Distagon* MM Distagon* MM Distagon MM Distagon* MM Distagon* MM Planar* MM Planar* MM Makro-Planar C MM Sonnar* MM Sonnar* MM Sonnar* MM Tele- Tessar 18mm 21mm 25mm 28mm 28mm 35mm 50mm 50mm 60mm 85mm 100mm 135mm 200mm F4 F2.8 F2.8 F2.0 F2.8 F2.8 F1.7 F1.4 F2.8 F2.8 F3.5 F2.8 F4

which is said to be as good as primes, and this is the way to use it on a Sony camera. Warning: this one is a bit risky, I would recommend only for professionals and really daring and advanced diyers. Take a look here. - We can offer a Sony solution for the excellent perspective control lens PC-Distagon 35/2.8 - Our client and friend Laurent managed to install our Contax mount on his Vario-Sonnar 28-85 NEW! Conversion instructions for the Vario-Sonnar 80-200/4 Questions? Info@leitax.com

- Some of the newer Sony cameras will need to communicate with a chip to work at all. You can easily glue a chip yourself or make it to be sent to me, I will install the chip on your Leitax bayonet for free. - As far as I know, the A100, A700 and A900 still can work in manual mode without a chip. - To have the Super Steady Shot system working properly, you'd have to order the correct chip with the max. aperture and focal length of your Contax lens pre-programmed in it. - I recommend the more advanced chip (the thinner model -M42C) from James Lao http://www.eadpt.com/ , if you want me to glue the chip in your bayonet, 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 Contax-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. - For metering, I use the stop-down method in Av mode, to have an accurate metering, remember to set the widest aperture on the Sony camera. - NEW! 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.

Now you can order the Contax-Sony bayonet here.

You may need a generic Sony/Minolta rear lens cap.

2 Euro

But, if you want the best, I can offer now the OP/TECH USA Sony/Minolta cap. -It has a rubber O-Ring that seals the lens from dust and moisture. -The O-ring also forms tight friction, it will avoid losing the cap. 9 Euro

With certain models, we'll have to manipulate inside the lens, it's not 3 Euro a good place for something metallic. With this plastic tool I don't make any scratches in the Contax lenses. I use this model for all the Phillips screws in the Leica and Zeiss lenses, it is industrial grade quality 5 Euro made by Irazola, and the design is very good, you can push and turn it firmly with the rotary end and the rubber finish. This silicone grease is necessary in case you find the lens' spring-ball Out of Stock 1 Euro system a bit dry. One tube is enough for dozens of bayonet replacements. Extra shipping cost for UPS Destination courier. I would need your phone number for the UPS shipping form.

Contax MM lenses instructions : All the MM lenses tested are identical inside, so the following instructions will work for all of them, and I am pretty sure, for all the rest.

These instructions are valid for the MM lenses with narrow mount only.

First, I would take a picture of the bayonet, so it will be easy to rebuild later

Some lenses have this curved piece here, we have to remove it. This one is the Sonnar 135mm.

Now, unscrew the three upper bayonet screws. Use a good screwdriver, not those cheap ones from hobby shops, these screws are glued to the threads and it is necessary to make enough pressure and turn them carefully.

And remove it.

Now, unscrew the bayonet.

And lift the diaphragm ring together with the bayonet.

Ok, it's better to cover the lens meanwhile we are working on the ring.

Now, we have to put the bayonet apart from the ring.

When they are apart, look for the bearing ball, it should be near its place, over the small spring.

Now look at this spring, we need to uncouple this side from the hook. Usually, there is a bit of glue to secure it, don't pull the spring, it can be deformed or broken, just scratch patiently the glue with a pointed tool or a needle.

The spring is free now.
