Tokina 11-16 on FF ?

I got 6D with 24-105, i have this Toki for 2 years, love it on Rebel ,i'm just amateur shooting vacation trips and landscapes mostly, but how is working on FF ? should i keep or sell it? Thx.

As far as I read on the net it should works on FF at 15-16mm. Someone else with more knowledgeable on FF will chime in.

The 11-16 is a crop body lens. While it will mount and might work on a FF body at its long end it will probably have some major vignetting.

I'd say sell it and pick up a canon 17-40 or tokina 17-35. Those are ff lenses and will give you the same "look" as a 11-16 did on your rebel (they will actually give you a bit more reach on the long then the 11-16 did on your rebel)

Do you have the 6D right now? Then try it out and see how you like it. I jumped to FF but will be selling mine in order to fund a 17-40.

This, it works at 15-16mm, any wider than that and it will start vignetting.

I have the Tokina 11-16mm as well, I would recommend you selling this lens and go for the 17-40mm or something even wider. As Im sure you are aware the Tokina is great on a crop but it will leave you wanting more on a FF camera.

I just sold mime. I could only use it at 16 on my FF. I still got vignetting. For me, it wasnt worth keeping.

If you have an off brand 1.4X teleconverter (or can borrow one) try it on the lens. This would end up being a 15-22mm f/4 lens on the full frame (this is equivalently wider in FOV than it was on the crop camera). It might hold you until you get a more appropriate UWA for a FF, or as an amateur it might good enough.

This works with with my Sigma 10-20 at all focal lengths with little to vignetting, pretty decent quality, and it still auto focuses.

From my understanding this works well with better with some crop lenses, and less so with others. This is why I suggest if you don't have a TC to borrow one first to see if it works well enough for you.

This will not work with Canon brand EF-S lenses, because they extend in the back (at least not without physical modification of the lens). With off brand crop lenses it works with varying levels of success.

Here is a link with someone doing this with the Sigma. If you do this with your Tokina, let us know how well it works out.

The Tokina 11-16 works fine on FF from 15 to 16mm. The problem is that one is limited to that short range.

Thanks for such useful information!

I have a 1.4x tele, and will certainly give it a try with the Tokina 11-16 on my 5DII.

P.S. Just went outside and took a few photos with my 5DII and the Tokina 11-16 mounted on a Kenko 1.4x teleconverter (will post later). Anyway, with the camera on Av the lens aperture was as I dialed it, which on the last photo was f/2.8.

I didn't notice any signs of vignetting at the edges and corners, except at 11mm.

Wide angle lenses all lack the pins on the lens to communicate the presence of TC to the body...even the Canon 100mm f/2 lacks these pins, while the Canon 135mm has these pins. As a result the body thinks that the FL and the aperture are both as reported by the lens, not as modified by the TC.

I see... I was not aware of that. By the way, I read the file information using CS5, and while the camera as well as CS5 showed f/2.8, the aperture value was f/7.1 whatever that means. The photos i took are just too crappy for me to post here

I noticed by looking at the images on the computer that there was no vignetting at the corners with the lens zoomed to 12mm and further. I will be testing this setup further and see how it goes, although I plan to buy the Tokina 16-28mm for FF.

I am puzzled by that comment...

1. a WA lens set to f/2.8 with a 1.4x TC on it would report f/2.8 although the actual aperture is f/4;
   
2. similarly a WA lens set to f/8 with a 1.4x TC on it would report f/8 although the actual aperture is f/8

Sorry I didn't think to mention that! It still technically is an f/4 though not an f/2.8.

Generally the reporting lenses what I’ve figured out is if the Canon lens (this was not true for one of my three Sigma lenses) has 8 contacts after the “fat/big” contact (so 10 total contacts), then it will register. If a lens has only 5 contacts (7 total), then it will not register correctly. Unfortunately having the 8 contacts, does not necessarily guarantee it will register.

How much vignetting was at 11mm, or post that one.

So it becomes a wide angle prime...

Didn't want to post these real bad photos, but you asked for them
This morning I stepped outside and snapped a few fast shots just to see how the Kenko tele would work withe the Tokina 11-16 on FF, so I did not worried about composition, horizontal level, and the rest. No PP (sharpening and the rest) done to the photos except for what CS5 does automatically. No tripod used.

11mm at f/2.8
