@CameraRick A computer monitor in a dimm room is enough. Close aperture, point Tokina to some dark area besides the screen: I used my mouse pad, part of the screen is in frame, blue dot in the center of frame, blue dot does not move like a normal lens flare, looks like a reflection between the two glas elements of the lens turbo.

Would be interesting if others have the same problem, as the two lens elements of my lens turbo are not locked together (I can move them individually) - maybe thats a problem?

@CameraRick yes it is some kind of lens flare, but this one is not moving when moving the camera - at least thats the problem with my adapter, which looks very strange in a video.

@Psyco not having a blue dot, only something like a purple one when at a specific angle towards the light; I'd call that lens flare. Tested with Tokina 11-16mm and Samyang 35mm

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

the Nikon to MFT is a snug fit on the BMPCC but not so with the Canon EF, it's loose.

What side is loose? Lens? If it is so, check topics we have, usually any adapter can be made tight with easy.

@gh2hacked thanks! :) Regarding that blue dot, I don't know how to provoke it. What do I have to do to get it?

@toca711 I find it actually really hard to focus this properly. You are 1m away from a wall, wide open, and try to get it perfect; no easy task :) you can see from the different color in the "CA" around that I was a bit off in both shots (wide open) You can clearly see the edges are a bit soft, yet the center looks fine. Positioning (as I have to move when adapter is on) is not too easy if you don't have a little setup for this, but I think it did the trick. Maybe I'll try again, with a Slider to move forward/bachward.

I did not have time to make some actual shots with it so far, as I mentioned I received it saturday but had way too much to do this weekend. This evening though I wanted to do some test shots with people in frame, in more of a real-world-scenario :)

Fun fact: the GH2 gets so wide in 16:9 that my Tokina 11-16mm starts to vignette very slightly in the edges at 11mm. A filter is not usable because you can see it immediantly at that focal length :)

@CameraRick

Thanks for first up testing, I think I will pull the trigger on this. I know this was no scientific test but your images seemed to show the turbo was sharper in the centre and a softer in the corners. Have you found this to be the case or was that jut a matter of focusing?

for anyone interested. Nothing scientific, but maybe worth a look. Mind the 'read-me's

I received mine on Saturday (pretty fast for germany) I'm actually surprised by the performance so far, I expected it to be MUCH worse. I can share some (not very scientific) tests regarding sharpness, wideangle etc this evening if you like

Sph1nxster 7:53PM Ordered mine... once i get it will post some video tests on a 50mm f/1.4 Canon FD. Any requests?

I'll be very interested in your findings with that lens. It's a bit soft at f1.4, maybe the booster will sharpen it up.

@nomad

With time all will be available.

Canon FD to m43 adapter is available. All terms as for other adapters - $134 shipped. PM if you are interested.

I'm wondering if one of those would fit : http://www.ebay.com/itm/Tripod-Mount-Collar-B-B-for-Canon-EF-Macro-100mm-180mm-/171034657665

Just like i said a couple of weeks ago ;)
