Before you get too excited, a “universal mount” in the motion picture industry is not universal. The universal mount is what is used on lenses such as the Cooke 20-100mm or 25-250mm, and more recently on the Angenieux 24-290mm. It’s simply a sub-mount with a threaded rear that allows several different mounts to be attached, most commonly a PL or Panavision mount. These were fairly common on professional zoom lenses in the 80s, 90s, and 00s. Now, wouldn’t it be awesome if you could put a classic Cooke 25-250mm on a Canon 7D? Yes. Yes it would be awesome. Please observe the awesomeness:
I recently gave a thumbs up to the Fotodiox Nikon – Eos adaptor as I found it to be the best combination of quality and price available. This mount allowed a lot of great Nikon glass to be used with Canon cameras with the exception of Nikons latest and greatest “G” series lenses. The G series lenses are Nikons latest effort to reduce the cost and complexity of their line up by stripping the lenses of their manual aperture control. The aperture is controlled by a small mechanical lever in the rear of the lens that interfaces with a similar small lever in a Nikon camera. Without the need for large, calibrated apart rings and fancy mechanisms for transfer a rotation, the cost to the consumer is (theoretically) lowered. Well thats great and all, but this left Nikon’s latest and greatest lenses, such as the 14-24, 24-70, and 70-200mm, at a loss since they required a Nikon camera body to operate the silly little aperture lever in the back of the lens.but now there are several work arounds for this. One of which is the new Fotodiox Nikon G – Eos mount adaptor. Basically the same construction as the current Nik-Eos adaptor, nut with a very small lever that interfaces with the lens as the camera would, but allows the operator to adjust the aperture. While this is a rather crude solution to a problem. While the lever only has travel of about 15mm, and there is no indication of F-stop, it works well enough. I found it rather difficult to obtain an accurate setting and repeat that setting. With a little bit of clever personal modification, it shouldn’t be difficult at all. So… If you have a great Nikon G lens that you love shooting with but want to use it on a 5D or 7D, then this is the mount you are looking for.
