tokina 11-16mm v Lumix 7-14mm

I'm using the $30 nikon g adapter (Nikon G AF-S F AI AIS lens to Micro 4/3, rainbowjiam) and the nikon version of the lens has iris control on the lens. Don't know what the difference is with the more expensive adapters? I also use a "Nikon G AFS Lens to Canon EOS Adapter" (search ebay) to also use it with a 5d mark II, with iris control.
 
Odd you said your Nikon version has the iris control on the outside? Mine doesn't...it can only be controlled with the adapter I have.
 
I use the f/2.8 11-16mm Tokina with a Novoflex adaptor and it is dead sharp over the entire range. I tend to use it at close to 11mm most of the time; anything wider I will tend to my Lumix 14-140mm. I would look at the adaptor (or a lens / adaptor mounting issue) as likely causing the problem; it's hard to see a lens with the displaying these characteristics passing QC at the factory.
 
After researching I realize my adapter is causing the issue and messing with the optics somehow. It works well at adjusting the aperture, and I like how it fits the lenses and such, but obviously something is off.

I have the NIKON version of the Tokina so I need to be able to attach Nikon F mount lenses (my other lenses are older primes). Can anyone suggest an adapter of this kind that owns the Tokina and knows for SURE that it will properly allow the lens to focus wide open.

I see Novoflex noted above...can you link me perhaps? There's so many knockoff adapters out there...I need to know for sure it's going to work.

I had a feeling the adapter was messing with the lens. Glad you figured it out.

Amazon has the Novoflex. I have it and its solid.

Both Abel Cine Tech, & Samy's, stock the Novoflex.

Samy's website often doesn't list stock, due to an arrangement with Amazon, so you might have to call them.

I've got the 7-14, it's my favorite Lumix lens. Super-mega-shockingly wide. Plus no need for an adapter, and hey, the iris control actually works... big thumbs up for the 7-14.

Barry: Is it possible to mount a 4x4 glass grad in a matte box in front of the 7-14 and not vignette the image @ 7mm? I'm seriously thinking of this lens for my outdoor nature/river work. With the Tokina 11-16 I almost always need a grad to knock the sky down.
 
I dont know the answer to your question to Barry, Scott, but super wide lenses often crush the extremeties(eg sky) inherently.

Never sure if this was a form of vignetting or the concentration of light gathered at the edges of a wide lens.

hmm, haven't tried it. The FOV is the same as a 5D Mark II using a 14mm lens, so it's really, really wide... I'm sure if the 4x4 was right up near the glass you should be able to get full coverage without vignetting, but I haven't tried it...
 
Thanks to Barry and Craig. Looking at photos of the lens, it appears that I could get the grad quite close and it may work. The characteristics of the lens might lead to some vignetting but I think I would still need the grad to equalize the sky exposure. The 7-14 would make a fine addition to the Lumix 14-45 that I also own - just wish the 7-14 wasn't triple the cost of the 14-45.
 
When I get home I might try the 7-14 with a standard 4" filter to see how far from the lens it vignettes. I don't expect it to be far at all.
 
Used both, love both. Comes down to what you need it for, if you need the extra stop vs the expanded fov etc....
 
Tested and returned the Rokinon 8mm and read the Nikon 10.5 thread regarding the Sigma 10mm and note that all 3 have a 180 degree FOV. Interesting that the Lumix 7-14 rates it's FOV @ 114 -75 degrees which is more of what I'm looking for. That should limit the w/a distortion which is overly apparent in the other 3 lenses.

Impressed with Barry's positive comments about the lens.

Will be interested in what mkfotos finds with a 4x4.

Regards,
Scott
