    @ICProductions You want to adapt nikon to FD to RJ in EF? That doesn't make any sense.

    FD has a much smaller Flange Focal Distance and needs corecctional glas elements which usually destroy the quality.

    The Nikon RJ Adapter can change Nikon G lenses' apertures, the EF one can not change anything, only passive.

    OK great. So does it make sense to go cannon fd and adapt to nikon (as Nikon mount really doesn't adapt much due to flange distance?) Has anyone had success with Nikon g - FD - RJ ?

    I'd like to also use MD, and Pentax with it.

    @ Vitaliy Yep....the RJ has the lock-open ring ...just like all the other adapters for fd lenses. You screw the lens on until it snaps into place, and then you move the lock ring in the correct direction. It also has the pin which engages with the lens lever so the aperture can be adjusted on the lens. As is obvious...it doesn't have any aperture adjustment ring. Beautiful and simple makes for good design principle. Wish the eos/m43 had aperture control cause those are the lenses I own, outside of fd and m43....but a vnd is a simple solution esp. for the 17-40. I think RJ has done a great job of releasing the fd/m43 at a third to a fourth of the metabones price. Next time I'm north of the rio bravo, I'll get the fd and probably the eos as well !

    @ Vitaliy

    This relates because someone said the fd version RJ had aperture adjustment. but if you insist, can you then repost my last post to that thread so at least nomad can read it -thanks

    Please with this questions to PM or FD to m43 adapters topic.

  • nomadnomad

    @kurth

    All FD adapters I've seen have a ring to operate the aperture mechanically just like the "Open" / "Stop down" button on the cameras. It's not meant to move the aperture to a specific value, though.

    Ok, sorry, let me rephrase.

    What is the most flexible setup, Cannon mount Focal Reducer and using a adapters for other brands ( mainly nikon)?

    I own both the Tamron 17-50 and 35-75 both nikon mount, which i adapt to m4/3. The 17-50 has no aperture control, while the 35-75 does.

    The Cannon mount focal reducer have manual aperture control like the nikon model, correct? ( so this wouldn't work with Nikon G lens)?

    So is my best bet just sticking with Nikon mount RJ?

  • Vitaliy_KiselevVitaliy_Kiselev

    The only downside is the canon mount doesn't have an aperature ring? So my tamron 17-50 is toast?

    You mean EF? EF mount lenses do not have any levers ala Pentax, Nikon, etc. Hence only specific electronic adapters can change aperture.

  • ICProductionsICProductions

    Well I guess that's one way to answer.

  • kurthkurth

    I think these are cheap enough to own more than one.

  • ICProductionsICProductions

    OK I'm about to pull the trigger on one of these bad boys but through more reading I'm having second thoughts on going Nikon or canon to m4/3.

    I already own three Nikon lens and was thinking about buying a d5200 for photos vs gh3 (whole other topic...) I was set to buy Nikon mount.

    But from what I gather, going canon offers more flexibility via adapters ( Nikon to fd ect) where going Nikon really only means Nikon glass. The only downside is the canon mount doesn't have an aperature ring? So my tamron 17-50 is toast?

  • kurthkurth

    What's even more confusing is that RJ appears to be allowing these to be marketed under different brand names as well, making identifying the particular manufacturer based purely on product images on ebay and amazon. I think I count about 6 different brand names, other than RJ, of these identical adapters ! And what's even more confusing is these offbrand retailers are picturing the wrong adapters in their descriptions. For example, one shows images of an eos/m43 on a fd/m43 page, which made understanding the situation more confusing still.

    And I found the dpreview link informative but obviously weighted to NEX cameras using fd mitakon lens turbos.

  • brianc1959brianc1959

    @dtr: Unfortunately, your dpreview link isn't relevant because it doesn't discuss any RJ Camera products.

  • kurthkurth

    @MarcioK well, maybe I live in a limited world but I've never seen an fd adapter with aperture control, nor can I even fathom a guess why you'd want one. Nor can I find one with a little googling. I see some fd to eos with focus confirmation. All fd lenses have an aperture ring . The nikon G to m43 focal reducer adapters have one 'cause alot of nikon g lenses don't have aperture rings and must be set in camera. The eos/m43 focal reducer adapter doesn't, so you'd either have to use a nd, or change the eos lens aperture on an eos camera. I'm sure RJ had a reason why they couldn't do the same on eos.

    Maybe someone could come up with fstop inserts like lensbabies ?

    I personally wish RJ had made the eos/m43 just like the nikon g....but they didn't ask me. Are you sure you're not thinking of "eos" to m43 or nex lens adapters having aperture control ? There's alot of eos to m43 adapters with control. I've seen a hundred of those. And I'm still tryin' to understand your "function" explanation. I think you mean "fully close" because you'd normally open the lens wide open, and adjust the aperture on the adapter.

  • MarcioKMarcioK

    @kurth A lot of normal FD adapters have it - the function, in this case, is to fully open the aperture in the adapter without needing to change the aperture in the lens.

  • kurthkurth

    I don't believe that's true about the fd version . All fd lenses have aperture rings.

  • MarcioKMarcioK

    @bruta030 I've bought a RJ speedboster, Nikon to m4/3, and it have the aperture control wheel - at least in the description, was not delivered yet. Looks like that the FD version have one too.

  • dtrdtr

    Has anyone seen a comparison between the RJ lens and Metabones Speed booster? Searched but havent found anything.

    Didn't try very hard, did you? ;) http://www.dpreview.com/forums/post/51792972

  • bruta030bruta030

    I know this is an apocalyptically bad question but does the speed booster have an aperture control wheel on it ?? That is if I have a lens that does not have a manual aperture, it I'll be able to adjust it on the RJ speedbooster...

    Another video test, this time the blue dot issue is disturbing me a little bit...

    Here are some photos from my first shoot using the RJ FD to M4/3 lens turbo.

    These were taken using a GH3 with an Canon FD 24mm f2.8 and 50mm f1.4 wide open.

    I am really happy with the results as far as sharpness and CA everything looks pretty darn close to 35mm equivalent and makes it much easier to get a wide shot in a tight space!

    For those of you who received the new RJ, is there a tripod collar mount that will fit this? I don't like having my lens hanging from my camera, especially the heavy Rokinon 35mm.
