Lens Adaptor to use Nikon lenses on Canon bodies WITH AutoFocus?

Does such an adaptor exist?

I just saw an adaptor that allows Nikon lenses on Sony bodies and still maintains autofocus.......why can't they do that with Canon bodies?

Or maybe they do, and I am just over looking something?

Thanks for any help in advance, I appreciate it.

I am looking to purchase the Nikon 14-24mm f/2.8 to use on my canon cameras.............my 16-35mm f/2.8 II just isn't sharp enough for my needs, and I need f/2.8 so the the new 16-35mm f/4 IS is not an option.

Sony is able to do it, because it is a mirrorless camera, and has a phase detect sensors built in to the sensor plane itself. It doesn't matter what lens is in front of it, the adapter communicates with the camera body and the sensor does the focusing. This feature is currently only available on the A7II and A7rII.

You cannot adapt a Nikon lens to a Canon camera and maintain autofocus. You can buy one with a focus confirmation chip, that will beep and light up when it believes focus is achieved, but the lens will have to be focused manually, and the accuracy of the confirmation is not always going to be perfect. If you plan on manually focusing at f/2.8- you'll probably want to be on a tripod and using live view with magnification.

What are you looking to use the lens for, and how wide do you need? Sigma has the new 24-35 f/2 if you need faster glass, but isn't really in the ultrawide class. Or you could look at the 24L.

Thank you so much for the quick response! I appreciate it

I understand now, it is all because of how the mirrorless Sony cameras autofocus with the sensor.....very interesting.

The lens is going to be used for Skateboarding photos (So No Tripod)........I use my 16-35mm f/2.8 II right now, and I only use at 16mm, I basically treat it as if it is a prime.

I have tried the 24mm f/1.4 II, and while it is sharper and faster than my zoom......it just isn't wide enough for the skateboarding photos I am taking.

I have thought about the 14mm f/2.8 II, but from everything I have read, it is basically the same image quality of the 16-35mm, there is not a huge improvement in sharpness, and costs a lot more money.

You may want to give the Tamron 15-30mm f/2.8 a try:

rokinon 14mm F2.8, that is what you want. Very sharp wide open, noticeably wider than a 16mm lens.

$250, no need to adapt any nikon

Thanks for that, I did not even consider that lens before, but I just read a few reviews, and for the most, people are saying it is very sharp!

Has autofocus, and is f/2.8.

I never owned or used a Tamron before, but I do have 2 Sigma's that I love.

Thanks so much for your input.........but that Rokinon lens doesn't autofocus, correct? Would be the same issue if I attached a Nikon 14-24mm?.......I am shooting Action/Skateboarding, so autofocus is must for me.

Did you look into the Sigma 12-24mm?

I didn't catch what body you are using.

Oops - just saw you needed f2.8. Sorry!

you probably wont need AF, the DOF is HUGE with a 14mm, just prefocus a few feet out, where you predict the action to be, and you'll likely be in focus. Stop down a tick or two, and you'll be hypo-focal.

I have the nikon 14-24, and it's a gigantic lens, but at 14mm, you should be able to get by without focus.

But he said he needs to shoot at f2.8. The DOF won't be huge at that aperture, surely?

it's pretty large, even at F2.8.

Assuming he's not shooting really really close like 1-2 feet away, should be able to prefocus outside of that, even F2.8. Even shooting in low light situations, MF an ultrawide 14 is fairly easy.

Wide open at 14mm the hyperfocal distance isn't too far. Just focus on your feet and you're good to go. This is wide open with the Rokinon 14 2.8

(Nikon still uses a mechanical lever)

<useless info>
They have finally started producing lenses with electronic aperture control. If the lens name has an E directly after the aperture ratio, you won't find a lever on the bayonet. I think the first was the 300/4E PF VR

I Need Autofocus and I Need f/2.8

I can't prefocus manually, because there is many times I am shooting sequences, and firing multiple fps......AI Servo can keep up with that, I myself in Manual focus can not.

And I need f/2.8 for the shutter speed, not for the depth of field, I want a minimuim of 1/1000sec

My Canon 16-35mm f/2.8 II does everything I want and need Except it is such a soft lens, the softest lens I own.

Nikon 14-24 & Rokinon, No because they can not autofocus.

So my choices are the Tamron 15-30 or spend a little extra money on the 14mm F/2.8 II L but probably only a marginal difference in sharpness.

These photos are being printed, and the sharpness really matters, if it was just for web I wouldn't mind so much I guess.

Thanks everyone for your help, I have some thinking to do.
