@CameraRick To get the blue dot, close the aperture on the lens turbo (the higher the f-stop, the more visible the dot) and have something bright near by, e.g. lamp, monitor (it doesn't have to be in shot!).

My tests indicate, that when having the aperture wide open, the blue dot is also there but it is spread out covering the whole picture with an invisible faint "halo" - it really is only a problem when closing down the aperture.

And yes, on the GH2 with its wider sensor, the Tokina 11-16 gets to wide with the Lens Turbo, but that is no problem for me, as I will cut top+bottom to get 1:2.35 aspect ratio;-)

I actually also have a tiny bit of play on the camera-end. Not too bad though.

In this case check camera mount and try few other lenses first. As usually such adapters are die cast, so all the same.

@Psyco Nah, don't have that? Does it only work with the Sun?

@Vitaliy_Kiselev I tried other native Lenses and Adapters, which are fine. On both, GH2 and BMCC, I have this tiny bit of play

Maybe I'm doing it wrong, but I don't have that. I never changed position of the elements

I see some green on your white walls (are they white?) in a few shots. I had the same doubt with mine. Is it the green issue of the gh2? Is it the lens? Is it the booster? Thx for the test anyway.

Yes my Canon EF version is loose on the camera side, on both the GH2 and BMPCC. Nikon version is almost too tight on the Pocket cam.

@IronFilm no, the Tokina 11-16mm works quite good with the Lens Turbo and GH2. Its just that you get some vignetting when going super wide to 11mm (this would be equivalent to a 8mm F2.0 lens!).

To avoid it, just zoom in a bit (to 12mm?) which will give you the same FoV when using the Tokina at 11mm on a camera with smaller sensor (GH1,..).

But I haven't used the combo on any other camera.

@gameb It's the evidence that the minus green-gel I just ordered for the LED giving a backlight is an investion worth :) It's the grading and the light, not the Adapter (this is shot on BMCC though)

@Tjabo I tried to also give a look at the edges, as those are (as you can see on any ISO chart) not too well. Yet I don't see a really big problem tbh. Personally I like what I'm getting from it - the 55mm for example is not a too sharp lens at all, but you can see how well e.g. the Samyang performs slightly stopped down! :)

@IronFilm It works perfectly with the GH2. SLIGHTEST vignetting (like, you see it on a white wall) at 11mm. Focus to 11,5 or 12mm and you have it out of the way - not a problem at all! :) I can make you an image of what I mean, but I'm not home tonight so it would be tomorro evening. I don't have another MFT Camera, but I can show you in 16:9 and 3:2 which is, from what I understand, what other MFTs record on the widest setting

@Psyco To be honest, I don't know. I have a fulltime job so you can imagine I only have time in the evenings to test this, haha :) However I did a test in my bedroom, and I could focus to everything (even 4m away), without reaching to infinity on the Lens indication. I want to make tests regarding this on the week end, when it's still bright outside to see for sure :)

@CameraRick @Psyco , thanks, that sounds fantastic about the Tokina 11-16mm!

@Adam_Mercier What the hell is going on with the bokeh in that shot with the guy?! Wow that is crazy. What lens is that?

I got mine in today as well. Here are a couple of screen shots. GH3, Rokinon 35mm, F4. Focus is on the Vegetarian Cookbook.

Is there any chance of a RJ Nikon F to Nikon 1 Lens Turbo?? If it is a 0.51x or wider like the one for the BMPCC that would be fantastic, but even keeping the same 0.71x would still be absolutely great!

Have no idea for now. If Nikon 1 will become big success, may be.
