Simple question:

Will this lens work with both Birger Nikon and Canon mounts?

If so, why a dedicated mount for Sigma?
 
I don't know that an official statement has been made regarding off-brand lenses. Anyone know if Sigma, Tokina, and Tamron lenses (in either Nikon or Canon mounts) would work with the Birger mount?
 
If a Tamron, Tokina, or Sigma has a Nikon or Canon mount on it, why wouldn't it?

On the other hand, Sigma also has it's own cameras, like the SD9 with the (in)famous Foveon sensor, for instance, and I think this has it's own lens mount. So that's why Sigma would have it's own mount. I don't think Tamron or Tokina, however, has ever had their own unique mount or a line of cameras, for that matter.
 
Given it's AF and it's going to be available in Canon/Nikon mount it should be communicating using the camera bodies respective languages, and therefore should understand the signals from the Birger mount and controls in just the same manner. After all the mount is essentially a canon or nikon body with the back removed and the controls that send the signals altered in the form of a bluetooth remote or focus knob.

I don't believe any Tokina lenses have been AF-S compatible yet, so probably won't have focus control on Nikon Birger.

Whilst not designated AF-S don't the Tokina have internal motors for their lenses that are powered by but not physically focused by the body of the camera? The Canon mount would require the lens to have such an internal motor. The Nikon perhaps not, but given most modern Nikon bodies support the use of lenses with internal focusing I don't see why Tokina would design the same lens twice, one with internal motor's (Canon) and one that uses the camera bodies motor (Nikon).

The only reason the Birger Nikon mount specifies AF-S Nikon lenses is that it can only be used with those that are controlled electronically with the motor within the lens itself and not by a motor in the body. AF lenses are driven in such a way if I'm not mistaken.

I might be wrong about the Tokina lenses though. But it would suprise me that they were making the older type of auto focusing system for Nikon, especially when they've made the electronically controlled lens for the Canon. And if they are making the electronic focusing system for the Nikon then it should be talking the camera bodies language and therefore the Birger mounts language since, as I said before, the mount and controls are essentially a replacement Nikon or Canon body sending signals to the lens to change position of the focus or iris.

I'm sure Eric or others will be producing a list of compatible lenses and how well they work with the mount.

The biggest problem for such lenses is having a crappy motor that doesn't have many steps. The best canon's have about 4000 steps whereas the worst have about 600. Eric posted a list of a few lenses a while back. The point is that the less steps, and the worse the motor, the less smooth the focussing will be. Lenses such as Tokina and Sigma's may suffer from not having good enough motors to produce fluid movement - But that's a maybe and I'm sure over the coming weeks and months we'll be able to test and collate a list of lenses that focus nicely.

According to the tokina catalogue they are in "AF-D" mount. Not AF-S.
 
Never the less, isn't the manual focus a viable choice beyond an useful auto focus feature?

Well if it's "AF-D" then the it's likely "arc form drive" and was the internal motor type used in older Canon lenses, which incidently are noiser and slower - and most likely have few steps in them, so the lens will have to be tested to see how smooth it pulls focus.

I'm guessing that the AF-S nikons silent wave motor technology is a similar spec motor to the USM's. But it would be great to find out the amount of steps in the various lenses.

"Tokina announced a 11-16mm f/2.8 lens for Nikon DX and Canon 1.6x cameras. This could be interesting, since it's designed to be an expensive, 9-blade diaphragm, high-performance lens and may or may not outperform the Nikon 12-24mm. It's got a 77mm filter thread and is traditional AF, meaning no AF on the D40 or D40x. "

As far as I can understand, Birger's focus control works the same as on the D40 -- needs AF-S, or equivalent (Sigma calls it HSM, I don't think Tokina has an equivalent).

Of course it can be used on Birger with manual focus, but that takes away much of the point of the Birger mount.
 
Based on the unique focal length and maximum aperture, this lens is almost worth rehousing if its quality is good. Then we don't have to worry about whether it has motor built in or not.

BTW, does anyone know the ball park cost of rehousing a zoom lens to "film production" standard? Who can do it in the US?
 
The atx pro series are nice and contrasty...
Not being into brand-fetish I intend to get the three tokina zooms at F/2.8 with some cheap old f/1.4 c/y zeiss primes 50mm, 85mm with adaptor for canon mount, and a big ugly AMD desktop with 16GB RAM, some NEO4K and CS3.
