new ciecio7 nikon adapter for DX and G

Mine came in yesterday, I went ahead and got the new one but it turns out none of the lenses I have found actually require it. Not even the Vivitar.

You only need the bolt for controlling nikon DX and G lenses because they have no aperture ring.

Beside the Tokina, have you tried other lenses G or non-G?

I haven't tried it on other DX or G lenses as I was primarily interested in controlling just that 1 lens (tokina 11-16). The micro 4/3rds mount will fit such a wide variety of lenses that it is pretty easy to get a great set without going to DX or G lenses. The exception to this is the wide end of the focal range. Especially fast wide lenses. As a nikon user the two that interested me were the tokina 11-16 f2.8 (which I bought) and the georgeous nikon 14-24mm G (which is out of my price range)

In another forum people complain about the Novoflex adapter that it does not fit some of the lenses. I am particularly interested in using it to mount the 35/1.8 and the Sigma 50/1.4. Thanks.

I tried the new ciecio7 adapter with a bunch of AIS lenses I have here and all attached ok. 24mm, 35mm, 50mm, 75-150 zoom (please note the bolt is not necessary to control AIS, only DX and G)

In some cases you may need to alter an old nikon lens because a piece of metal at the back of the lens might bang into ceicio7's bolt. I had to do this on my nikon 35mm/1.4 when I put it on my canon 7D as the metal hit the EF contacts. If you do decide to remove it don't use a hacksaw as metal dust will get everywhere. Use a pair of pliers and bend it carefully. Repeat until it snaps, you should get a clean break ... and be careful not to bang into the nearby glass surface.

This pic is not mine, I got the link from a 5D thread, but it shows what I am talking about

What makes this Ciecio better than the Novoflex? The Novoflex has an integrated aperture control ring.
 
I ended up buying and using the Novoflex and it has one little disadvantage; move the lens a little and aperture may change one step. Does the Ciecio have the same problem?
 
Ok I will try to explain in my best English... you mount the lens on the camera-body, it says "click" and it's locked, but you can still turn/twist the lens a little, let's say a tenth of a millimeter to the left or to the right. That's normal. But when you do that using the Tokina/Novoflex/GH1 combination, aperture may change one step.

How is that with the Ciecio? Oh well I'll just buy one anyway, I just purchased my second GH1 with another Tokina so I'll need another adapter anyway and when using two different brands I can compare and see which one is best.
 
Thanks, that's clear now. Just tried that and didn't feel it move at first. You really have to kind of work at it, but it does indeed shift just a hair. I've only used the Novoflex with lenses that have manual aperture rings and haven't noticed it's a problem.
 
I just gave it a good look and there's definitely more than a hair of moving space here, more like 1 mm or so and it's very easy to make the lens turn a little and by doing so, changing the aperture by one step. Maybe my Novoflex is a bit faulty, or maybe it's the combination of Novoflex and Tokina, I will e-mail Novoflex about it.
 
I am still hoping if someone could tell me why ciecio7 adapter cost about $150 and the one I linked cost $30. Nothing much?

No one knows it (look at other thread for $3 Nikon adapters) :-)
But I suggest to find on ebay one with different lens fixing pin unlocking approach.
As I find it hard to remove the lens on this one.
