    Just received my M42 adapter. Great quality and arrived in 7 days. Love these things.

    I was wondering if this will work with my BMCC EF mount? and EF lenses?

    Of course no.

    So the order for an M42-to-Fuji-X will be sent to you today or tomorrow :-) Thank you!

    Leica to Fuji is impossible to do (too close) - http://en.wikipedia.org/wiki/Flange_focal_distance

  • hilburgerhilburger

    So, finally I am close to getting a Lens Turbo, probably an M42 to Fuji-X. Is there maybe also a Leica-M to Fuji-X? Couldn't find further information on that.

    Thanx and best regards from Germany!

    So somehow this has not only to do with the adapter but also the glass of the lens? I'm trying to understand this, can someone explain this?

    It is mostly due to reflections from the lens closest to the sensor. If coating is very good and lens is further from adapter glass it is better.

    @d3strategies thanks for your reply!

    The thing I don't understand is why there is this blue (or green or purple) dot with one lens and not with the other. I see the dot with my fd 28mm 2.8 lens, even indoor and far from a direct lightsource. And with my fd 50mm 1.8 there's no dot at all. So somehow this has not only to do with the adapter but also the glass of the lens? I'm trying to understand this, can someone explain this? If I buy another 28mm will there alsobe this same problem?

    I just purchased the RJ Lens Turbo through personal-view.com deals (thanks @Vitaliy_Kiselev). I've only played with it for a bit but so far so good. I had recently purchased a cheap Pixco dumb adapter so I could mount my Nikon lenses on a G6 and noticed that the mechanism that controls the aperture would not allow me to fully open the aperture. The pin simply does not line up with the aperture control on the lens. The Lens Turbo, however, works perfectly in this regard.

    @snvid I assume I have the latest version since I just received it May 4. Looking through the viewfinder or at the screen and pointing the camera directly at a light source, the dot is definitely there. It's color, size and intensity changes depending on the lens and the f/stop used. I've seen variations from a strong green dot to a bluish or even multi-colored flare. But again, this was pointing directly at a light indoors so I'm not sure how much of an issue this will be in real world shooting or how an actual recording will compare to what I'm seeing in the viewfinder.

    See PM.

    It would be helpfull if I knew the dimensions (diameter) of this tripod mount ring collar.

  • Vitaliy_KiselevVitaliy_Kiselev

    Will the pka version work with older pk mount lenses? If one puts the aperture lever in the 'full open' position will the aperture ring setting be in effect?

    Of course.

    For any modern lens where body is able to control aperture - adjustment will work.

  • hilburgerhilburger

    @vitaliy Awesome, so it's about time to choose the first one :)

  • nomadnomad

    I can confirm that for my Minolta SR model which arrived about 10 days ago.

  • ScotScot

    @snvid I don't believe the issue is totally gone but it only shows up for me when I point it directly at the sun and have it set for high fstops. So try not to point it at the sun and keep your fstops down and I really don't think it is to much of an issue. You can even think of it as a look like anamorphic flares sometimes you just have to go with it.

  • Vitaliy_KiselevVitaliy_Kiselev

    @hilburger

    Yep. All of that you mentioned.

  • hilburgerhilburger

    Dear Vitaly,

    I just ordered an X-M1 and would like to know if the RJ lens Turbo is also available for XF mount, to mount e.g. M42, Minolta MD or vintage Nikon lenses on this cam?

    Thank you and best regards, Thomas

  • snvidsnvid

    Are there any new RJ owners here? I read somewhere that the blue dot issue is gone with the latest version. I bought mine in Februari but it still has a blue dot (more like a glow). So I probably don't have the improved version.. :(

  • SpencerSpencer

    Hey guys, has anyone here had experience with both the latest RJ and Zhongyi? I have the zhongyi from b&h with an ef 28 1.8 and rokinon 50 1.4. It seems to work pretty nicely, but I have nothing to compare it to and no panasonic lenses for my gh4. From what I heard, the ef version of the zhongyi came out at the release of the 2nd version of other mounts, making them the same optics (don't quote me). Rj has a listing of their adapter with a gold accent ring and says that it has a new optical design. Not quite sure when their "new design" was released but I'm really curious to see how these compare.

  • soulkeepersoulkeeper

    Trying to decide which mount of sigma 18-35/1.8 to buy for my gh4...both mounts of rj speedbooster works well with this lens on gh4 (except the fact that you cannot control aperture with the canon mount version) Thanks!

  • joetheprojoethepro

    @Scot In case you cant find it, the quick answer is there is a little set screw that holds the glass tight in the adapter. Loosen this, and then carefully physically screw or unscrew the glass element to move it. It doenst take much to have a effect on infinity focus. Just turn, test, turn some more, test...

  • ScotScot

    @vitaly Thanks I will hunt it down guess my quick scan thru 27 pages was to quick :)

  • Vitaliy_KiselevVitaliy_Kiselev

    @Scot

    Yep, look at the early posts. You'll need slightly adjust optical group in adapter.

  • ScotScot

    Finally got my adapter and so far looks good. I did find something I have not seen discussed much.

    1. Infinity focus way off my olympus 35 to 70 hits infinity at about the 8 foot mark is this normal? I saw a fix mentioned is there a video out there showing the procedure?
    2. My Olympus 35 to 70 was parafocal now it is way off anyway to fix? Same as above? Video?
