Welcome to Leitax, this is our Olympus-OM to Pentax-K page. After several requests from Pentax users, we can offer now this new replacement bayonet to use OM-system Olympus Zuiko lenses on Pentax bodies.
-This conversion is fully reversible
and will not damage either the lens or the camera.
-The Olympus-OM lenses will focus to infinity and will maintain the aperture click stops
-The Pentax cameras will show a focus confirmation light in the viewfinder.
One of the holes at the bayonet coincides with the positioning slot,
therefore, the spring loaded pin at the camera will work, but the lens
can be moved half millimeter to the right or to the left if you force
it. This is not a problem when taking pictures, the focus and aperture
rings operation will not move the lens.
Please take a look at the instructions on the left, and don't hesitate to ask me any doubt with the conversion.
I have the K20D, but I think the settings are similar on other models: in the Custom Setting menu, go to "Using aperture ring" and set "permitted". This way, your camera will work and meter in Av mode with adapted lenses.
For my calculations, all the lenses checked in my instructions will not hit the mirror of a Pentax camera.
The orange mark at our Leitax mount is the exact scale center of the Zuiko-OM lenses. And it can be used as a rough guide to mount the lenses on Pentax cameras, as it is very near of the red dot position.
This is our Pentax K mount for Olympus OM lenses.
Also included a piece of spring and an useful needle with hook to install it.
|You may need a generic Pentax-K rear lens cap.||
|But, if you want the best, I can offer now the OP/TECH
USA Pentax-K 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.
-It covers the entire bayonet diameter, providing more protection against blows and scratches.
With certain models, we'll have to manipulate inside the lens, it's not a good place for something metallic. With this plastic tool I don't make any scratches in the Zuiko lenses.
I use this model for the Phillips screws in the Olympus OM lenses, it is industrial grade quality made by Irazola, and the design is very good, you can push and turn it firmly with the rotary end and the rubber finish.
|If you don't feel confident after reading the
instructions, please send
your Olympus OM lens to me.
Provided your lens is in the list, we can install a Pentax bayonet on it.
Notice this price doesn't include the bayonet nor shipping.
shipping cost for fast courier.
I would need your phone number for the courier shipping form.
