No unfortunately not, apart from the Mamiya 645 lenses. I modify still lenses to ef mount and make them more usable for filming. There is EF mount for Alexa cameras so you can use these lenses on Alexa. To buy a modified Set is a great way to test lenses and if you truly love them you can still rehouse them by a reputable rehousing company later on.

I don't offer parts for the conversion unfortunately. There is specialised online retailers : www.followfocusgears.com www.simmodlens.com www.leitax.com

The cases come from www.precisioncases.com.au

I don't repair customer lenses, I personally use a Leica trained Lens technician www.europeancameraservice.com
