Nikon lenses on a 7D
 

I bought a Canon EOS 7D a couple of days ago with an 18-135 mm zoom lens that came with the package. Being used to the extremely narrow depth of field that comes with the combination of original Letus35 adapter and Nikon primes, I'm now considering using my old Nikon primes with the 7D. I'll need some step-up ring though, I guess.

Anyone knows the simplest way to get these step-up rings?

You don't need step-up rings, just an adapter.
Look on Ebay for Nikon to Canon EF adapters.

The Fotodiox Pro is well regarded. I think that it's worth getting one. You could also get one adapter per lens. You might consider a bunch of cheap ones if you will outfit many lenses. But having one reference adapter is nice. If you ever find that the focusing is a bit off or the fit is a bit loose on a cheap adapter, you won't be stuck.

I bought one of the Kawamall Nikon to EOS adapters recently, and I was VERY pleased with the fit. We have a short coming up next month, and I wanted to mount my Nikon glass onto the 5D we will be using in production. No complaints and it was $15. It was an EBay seller/business going by Kawamall. I do wish the edges were given a bit of attention, but a little sandpaper should sort that right out.

Thanks for the great advice from everyone.

I bought 5 of the Kawa adapters last year, for various lenses I have, and I have had no problem..

I have several of the Kawamall adapters too for my ancient pre-AI Nikkors, which are better than any of my newer L or Zeiss lenses, No problems at all. Only thing, on my f2 35mm, the meter says I need another stop when I really don't. No problem since it's consistent.

Bill: I mounted that same lens on a shoot on T2i two days past, and was very happy with the footage...

It's my favorite lens. Sharper than any others I have.

It was a favorite when I was shooting 35mm adapters. Makes a great normal for the APC size sensor. The 1.4 Nikon 50 makes a great portrait size for that camera too, though I think I like my 50mm 1.4 Pentax K mount better in terms of performance.

Regarding the adapters.

I have read somewhere that Canon mounts differ, and that adapters that work well on FD bodies can actually harm EOS cams.

Is it true? Or is that just some Nostradamus talk?

You cannot mount an FD lens onto an EOS body, and thus you cannot mount an FD adapter onto an EOS body. Use the correct adapter and you should be fine.

The Reason Nikon lenses tend to be so popular is that they have been essentially unchanged (physical size) in 50 years. They have had electronics and other things added, but a 50 year old Nikon lens, will still fit many Nikon bodies. And any Nikon produced after the early 70s will fit practically any current Nikon body. I have a 1974 300mm Nikkor lens that I mounted on my T2i today and it worked beautifully.

I can't seem to dig out the original web link. But the author said that some adapters that are mechanically fitting, can actually damage EOS electrical contacts.

This one.

Nikon G - Canon EOS Adapter

It'll change your life!

Well, that seems interesting. However for numerous reasons, I prefer manual glass still. As far as optics being better in the "G" lenses, well that's certainly a matter up for debate. What I can tell you is that I would MUCH MUCH rather attach at follow focus rig to an older and high quality manual lens than any of the modern ones.

You can attach a follow focus to a G lens. They can be set to focus fully manually. The Nikon G to EOS adapter (from 16:9) allows you to have manual control over the aperture, since G lenses have no aperture ring. Focusing is done manually ... whether by hand or by follow focus. I have a 14-24/2.8 G and a 24-70/2.8 G that I use with with my 5D2, along with a 80-200/2.8 ED D. It is generally accepted that the 14-24 G lens is one of the best, if not the best, wide angle zoom lens in the world. Check out Focus Optics. Their "Ruby" lens is based upon the 14-24. It is designed for Red One and for cine work. A cool $15,000.00! You can pick up a used 14-24 G for about $1,400.00 and have basically the same optics.

I also prefer manual still glass. I have a whole collection of Zeiss lenses. All primes. However if you want some killer zooms, then take a look at the Nikons, especially the two G zooms I mentioned. The only real disadvantage to them (other than the expensive and hard to get 16:9 adapter) is that they are big and very heavy lenses.

Thanks for the info Bill. I've really not considered the "G" lenses for several reasons. One is because I don't know how they will work with my Nikon film camera (F65) and the other is the difficulty in adapting them for Canon use.

I know that when I buy Canon glass, it's for my T2i only. But when I buy Nikon glass, I want it to work with my F65 as well. I miss my F4s, but what can I do.

I have shot plenty with the Nikon G Series 17-55 f2.8 with the 16:9 Adaptor. Alongisde a canon 16-35mm f2.8 and a Nikon 80-200 f2.8 and they are all fantastic. Advantage with the G in a 16:9 is the smooth aperture motion and it has it where it is supposed to be on a Video camera!

They cost though. Just bough a second for my Sigma 10-20 f3.5. I also have lots of Nikkor primes but for what i do they are a nice idea but quite impractical.

I think you would be wise to keep an eye out for G series for your 7D.
