Tokina 11-16 Aperture Control?

A bit of research has convinced me that the Tokina 11-16 mm F2.8 zoom is what I want for my wide angle needs below 20mm (at 20mm and above fast fixed AIS Nikkor lenses will work for me). I will be using a Nikon mount on my Af-100.



The Tokina advantages are:
  • excellent optics and mechanical (according to Ken Rockwell, etc.)
  • fast - 2.8 and fixed aperture through zoom range
  • very affordable - $600 +/-
The major drawback is the general* lack of aperature control.
* except for $3500 Duclos model, which is too expensive for me
* except for Q-tip/ drill and tap holes in your adaptor mods, which are too klugy for me
* except for always shooting wide open and using ND's to control exposure, which I don't want to do

Are there any other proven solutions to contoling the aperture on this lens on a Nikon mount?

Usually you cannot control aperture in digital lenses when you use a micro 4/3 adapter but this is not true for Nikon lenses.

There ale a lot of adapters for nikon lenses like this

This is a polish one, but there are several similar chinese adapters on ebay

You can modify continuosly the aperture using a screw or a little lever but you don't know the exact value (this is not a big problem, in my opinion)

Birger will probably be supplying a Nikon adapter that provides for proper aperture control on aperture-ringless lenses. Not available yet, but maybe by the time the AF100 is released.
 
Thanks for this great information. Looks as if the Ciecio7 will let me control the 11-16 aperture - except that it won't provide any
numerical F-stop data - right?

Right... but you can find also cheaper ones, as posted by others.

If you can, look for adapters that maintain the aperture value: a screw is better than a lever because there's less risk that you can change the f stop value touching the lens
 
This has been the one issues stopping me from pre ordering the camera. I am scared to death that I will not be able to get a wide, fast'ish lens that will allow me to control aperture manually. Plz post stuff whenever you find out anything relevant to this guys. thanks!
 
I use one from Hong Kong (jinfinance I believe) with a Tamron 17-50 Nikon mount. It's the type with the ring that you turn instead of a thumbscrew. It works great, although the fit is tight and it's a tiny bit tricky to put on and take off. I just leave the adapter on the lens at all times. Let us know what adapter you get and what you think of the Tokina. By all accounts, it is The Stuff.

You can get extremely wide, extremely fast lenses right now. They're just not cheap; there are 8mm & 10mm cinema primes that are f/2 or maybe even faster. So it depends on your price bracket. Or you could just wait for Birger to finish their electronic mount, which will let you use any non-iris-ring lens on the AF100 (including that Tokina 11-16). Or you could go with the Panasonic 7-14, which isn't all that fast (at f/4.0) but is extremely wide, 7mm is way wider than the Tokina's 11mm.

Or you could get the Olympus 4/3 lens, which covers the same range (and more) of the Tokina; it's 11-22mm, and f/2.8-f/3.5. So at the wide end it's every bit as fast as the Tokina, and while it's slower at the tele, it's also substantially longer on the tele end (22mm vs. 16mm). I would guess it's probably the same 2.8 through 11-16, so it's probably a direct match for the Tokina. So it's got a longer range, just as fast, and costs about the same as the Tokina. Not sure if it has a manual aperture ring or not, but it can definitely be controlled by the AF100. Sounds like there's nothing to be "scared to death" of! :thumbsup:

I should have been more specific. Wide, at least F2.8 and under a grand. I just want to make sure I can use my AIS lenses and then get one wide zoom that will allow me to control aperture manually at around 600 bucks if possible.
