Premium Member Sean Cheung Posted July 5, 2023 Premium Member Share Posted July 5, 2023 I'm looking for extenders for some Arri-S bayonet lenses. Ideally I'd like to find a 1.15x or 1.2x Extender. I believe there used to be some Optex conversion kits that were often used. If anybody has any hanging around please let me know! Link to comment Share on other sites More sharing options...
Site Sponsor Barbara Holler Posted July 5, 2023 Site Sponsor Share Posted July 5, 2023 HI Sean I have a Colcine Super 16 x2 extender and I have a Precision Optics 2x Extender for Super 16 as well. Would either of these be of interest? Link to comment Share on other sites More sharing options...

Can you let me know the costs of your 2x extenders though please, either on this thread or direct msg. Many thanks! Link to comment Share on other sites More sharing options...

I’m not sure anyone ever made short extenders like that in Arri B mount or S mount, it was only ever 1.4x or 2x. And they generally don’t work with wide primes, only zooms or primes with minimal rear protrusion. The Optex conversion kits were replacement rear optics for the Zeiss 10-100 mainly, though I think they may have offered some for other zooms too. But they would have been all used up by now, I haven’t seen one for sale in many years. Maybe you’ll get lucky. Link to comment Share on other sites More sharing options...
Mustafa Uzuner Posted July 5, 2023 Share Posted July 5, 2023 There are relatively recent Veydra extenders from PL to PL but I believe they only work with a handful of 35mm zooms. https://visualproducts.com/product/veydra-1-2x-pl-to-pl-expander-extender/ Link to comment Share on other sites More sharing options...

I wasn't aware that the Optex conversion included replacement optics! I assumed that it was just like an extension tube that could attach to rear of lens. It is indeed a Zeiss 10-100mm which I'm dealing with, but there is also a 9-50mm which I was hoping to use more extensively beyond R16. (I.e. maybe on a S35 sensor) Link to comment Share on other sites More sharing options...
