I''ve narrowed down my selection bewteen either the Canon or Nikon manual lenses for the Letus 35. I noticed that the Canon is listed as "Canon FD Mount" for the manual lenses (I believe both the old and the new FD mounts should work). The Nikon simply says that it needs to be "Locking Mount", but I'm not sure how to look up cameras like this when searching on eBay. Do the applicable Nikon lenses have some kind of designator on them to show that they will fit on the Nikon adapter of the Letus? I noticed on one of the pages on the Letus site that it showed "Nikon AI Mount" as being accepted. Are these the only types of Nikon lenses I should be looking for on eBay? Or will all Nikon lenses fit the adapter as long as they are "Locking Mount"? If so, which Nikon lenses are locking mount?

Also, If I'm not mistaken, it looks like the Canon and Nikon lenses are both rated very close with repsect to image quaility. Let me know what your preferences is and why. I have seen that the Canon FD lenses are plentiful and relatively inexpensive. I do know I need to look for lenses with at least an f-stop of 2.0 or lower due to the inherent light loss with the Letus.

Thanks.

Hello, the "locking mount" information you see on the site is only related to the mount itself, not the lens. This just means there is physical locking mechanism in the lens mount to hold the lens in place.

When looking on ebay, search for Nikon AI or AIs lenses and you will be fine. I would recommend the Nikon AI 50mm f1.8 as a great starter lens. Nikon AI is the most popular mount we sell. In short, about any Nikon lens will "fit" the mount. Your best bet is to stick with the older AI lenses though as you want full manual control over focus and aperture. Some of the newer lens are electronic which can be hard to work with on a 35mm adapter.

Canon FD lenses are great lenses as well. I use both Canon and Nikon on my Extreme and am happy with both. If I had to choose one over the over, I would go with Nikon. That is based on a lot on my own personal opinion though. Others may argue for or against that stance.
