If I'm not mistaken, you can use some old Leica lenses with your Nikon but you have to use adapter. I'm not sure exactly which one, the reason I have no idea now is maybe because I found out it was too much hassle or too costly, hehe...

That Knoptix does have some very interesting bokeh, and I can see why one might want such a tool. No different than an instrument that has a particular sound, it might not be universally appealing, but if one can find the right way to apply it, more power to them.

FWIW I really like the flower bokeh behind the woman, whereas the bokeh behind the man does look a bit more generic.

I got my D40 a few days ago. I've been playing around with it incessantly. Here's one photo that makes me giggle every time. (it's just begging for an lolcats-esque caption, but I haven't thought of anything good yet)



Suffice to say, I've been having fun.

I had exactly the same reaction as I scrolled down and that picture came into view! How funny. Enjoy the D40!

Probably not, since they use different mounts. There may be an adapter that allows a switch between one (extension), but people seem to find adapters reduce image quality. I know you can use nikon lenses on canon's with an adapter, but you can't use canon lenses on a nikon. Most people won't do this though, because an adapter is needed which people claim reduces the image quality of the lens.

Leica lenses are bloody expensive to boot!

Leica lenses will not fit on Nikon mount with a glassless adapter. The problem is that Leica M lenses (the rangefinder lenses) are designed to be about 27.75mm from the flange to the film/sensor. Nikon F mount flance to film/sensor distance is 46.5mm, so you could put a Nikon lens on a Leica, but not a Leica lens on a Nikon. If you did, you would only be able to focus extremely close up. Leica SLR lenses work on Canon, but not on Nikon. The reason is that Leica SLR's film to flange distance is 47mm, which is too close to Nikon to machine a durable adapter...it would have to be .5mm thick. Canon film to flange is 44.0mm, which is enough to machine an adapter.

Assuming it is properly made (this can be difficult...they need to be highly precise), the adapters have no effect on optical quality. You will have to use stop-down metering though, since the adapters are generally simple mechanical couplings that cannot stop down the lens or control the iris. This also limits you to using only lenses that have an aperture ring (all Leica lenses do, luckily).

Anyway...that's why you can't use Leica lenses on Nikon (unless you rip the mount out of your Nikon camera and put in a Leica R mount...something people have done before.)

I wasn't aware that you could use Nikon's lenses in a Canon mount, even with an adapter. Do they retain any electronic coupling after they've been modified?

Wow I had no idea they were so expensive! $6k for a 50mm f/1 with an average price of around $3-4k Geez. At least Zeiss lens are relatively affordable...

Thank you very much for the technical explanation.
