Low light huh?

Don't know if this is the case, but try looking at the aperture actuation pin or lever inside the Novoflex adapter and see if it is bent or otherwise missaligned. If all looks well with the adapter, I agree with the suggestion of trying some tape to build up the pin or tab to further press on the lens tab to open the aperture all the way. You can try cheap tape first, but for a more permanent solution, I recommend aluminum tape, often called speed tape by auto and airplane racers.
 
Your shooting in a dark car driving down a dark residential street with practically no street lights! How bright would you expect it to be?! It's pretty funny when people complain about cameras not being "low light enough." That's part of our job, to light the scene! The most important part.

FWIW the OP has never stated in this thread that he thought the AF100 wasnt low light enough. The query was, should the shot be brighter considering his settings. Pretty valid since he has no direct comparison available in front of him.

To OP, sorry as I have no idea about Tokina lenses so I need to ask, its manual or auto aperture?

I use a novoflex adapter (on manual lenses) and it doesnt cause any light loss. I dont use the novoflex aperture adjustment ring. I just leave it closed down where it has no effect and adjust aperture on the lens. In the pictures you have your novoflex aperture adjustment ring turned toward open, if your lenses are manual or you have some way to control the actual lens aperture it should be in the closed position. If your using the novoflex aperture adjustment ring to control your aperture, the fully open position it not all the way to the large O indicator, so your photo seems about right.

I would however suggest as well (as others have mentioned) these images are very low light so it may be as much as you can get under those conditions. If your in the middle of a city for example "low light" isnt actually that low. But a good suggestion by someone was to compare on another camera, got a DSLR handy?
 
John,

Have you removed the lens and adapter from the camera to see how the aperture ring works? On all these lenses there is a tab that controls aperture, and it's easy to see what the maximum range of motion is. My novoflex has the exact same issue you describe (not aligning with the marks), but this is because of the lens. The adapter cannot physically open any more, even though the ring markers give the illusion that it should.

Think of it this way: say the range of motion of the novoflex ring is 15mm. The aperture interface mechanism on the lens is only 10mm. So of course the markers won't align, but it's still accessing the full range of the lens.

I would investigate this issue before continuing. I don't recall you mentioning ever doing this.

Hmm I have the Novoflex adapetr which I have bought while waiting for my AF101 to arrive. I have only tested it on a couple Nikon to see if the fit snuggly. However reading this post I tried again and noticed that the blue ring also doesn't turn fully once a lens is on tight. It also messes with the operating of the manual f-stop ring.

I'll play around with it some more.
 
Oh okay.. So with the Novoflex when you attach a lens the blue ring needs to be turned fully anti-clockwise. To have use of the manual lens ring the blue Novoflex ring needs to be turned fully clockwise.

Should it also be possible to control to aperature by the Novoflex ring?
