    Re: JLM L-plate for A7/R

    looking over the L-plate with battery grip, i have a question:

    typically i make my L-plates so the camera lens can be centered over the L-plate in portrait mode, however, the extra thickness of the battery grip means the L-plate would need to be another 2" longer, a total or 4-1/2" tall, all supported from the bottom plate. if i used a typical 2-1/2" L-plate, the camera would be better supported, the overall bracket would be tidier in size, but the lens center would be 2" off the center of the plate.

    what do you think?

    Re: JLM L-plate for A7/R

    Just reading this message, and I'm desperately in need of A7R+Grip L Plate.
    Actually, I use A7R with metabones adapter and Canon lenses, and can't mount the vertical grip without losing ability to clamp adapter foot. (see this blog post)

    What I dream of is an 'always mounted' L bracket on vertical grip, not ruining handling, and without any part to slide or move or unscrew/screw to open battery door or slide connections doors. I don't want to use a screw key each time I need to get battery out etc. The side part of the L could even be on another plane (toward the lens) to free grip battery door (my RRS 1DsII L-bracket is like this and never bother me). Not being perfectly centered between portrait and landscape isn't a problem too.
    But having to screw and slide would be a definitive no-no.
    Now, can't wait to see your design. I was about to design one in 3D and get it machined, but not much time right now.

    Re: JLM L-plate for A7/R

    Received this mail today:

    Update for Really Right Stuff Support Case #3417 - "L-Plate for A7r with Battery grip."

    We are in the process of researching and designing a custom plate for use with the added battery grip on the Sony A7/A7R. If we decide to make a custom plate for use with the added grip, you will see such an announcement made on our website homepage as well as on our company Facebook page, and in our monthly newsletter.

    Please let me know if you have further questions.

    Re: JLM L-plate for A7/R

    my design is complete and will get machined this week. i decided to keep the L-plate end at 2-1/2" above base of grip. should a taller plate be required, it could be retrofitted.

    Sony has chosen to make a huge battery door in the grip, and there is no practical way to allow battery access with the grip plate installed that I can come up with without compromising strength or add a huge offset (ruining handling). it is not such a big deal to use an allen key, loosen the plate from the grip, rotate it out of the way and change the batteries. since there are two batteries, the frequency of change will be longer anyway.

    Re: JLM L-plate for A7/R

    hmm...earlier response disappeared

    unlike the Canon, the sony uses a hinged battery door and the swing is problematic

    i will look into a tool-less fastener

    Re: JLM L-plate for A7/R

    What I think frustrating on your 'without grip' version is that you can't let it slided. I'm 90% of time on tripod with connected cables, so I would let it always slided. But due to the part under the door, I couldn't do that. I would have cut this part to use it ;-)

    Re: JLM L-plate for A7/R

    ???
    my L-plate versions CAN slide; the bolt opening is a slot allowing enough movement so you can open the doors, attach your cables and still fit on the tripod in portrait mode. difference between mine and RRS is mine is one piece.

    that concept does not work with the grip version because of size of the battery door, but the cables are still accessible

    Re: JLM L-plate for A7/R

    Of course yours can slide, what I want to say is you can't let it always slided for cable doors access, as it block battery door.
    I'm not saying this one is better, this one is badly designed etc, don't get me wrong. Just putting some ideas about designing the best one. And yes you are entirely right, the sony vertical grip door design is very bad regarding L bracket fitting.

    Also, are you confident enough in vertical grip screw fixation to handle let's say body+grip+metabones+24-70 2.8L II ? Of course with a 70-200, it will be mounted on tripod collar, but dunno if grip screw and sony lens mount are as robust as Nikon/Canon DSLRs ?

    And on a curious part, how do you design it ? Do you use some 3D tools with a 3D model of A7R+grip ?

    Re: JLM L-plate for A7/R

    i measure the camera shapes using calipers and micrometers and a coordinate measuring machine; drawings are done in 2-d Autocad (usually going through several iterations), then CNC machining programs generated. The profiles and interior cutouts are done from plate on the CNC waterjet, then the exterior machining and detailing done on a vertical CNC mill (three or more different tools used)

    all of my bases rely on some sort of mechanical stop (in addition to the screw) so the base will not rotate. for the sony with vertical grip, i am using the series of grooves in the rubber base, making matching ridges in my baseplate. probably the weakest point will be whatever secures the metal tripod threads into the plastic of the grip itself.

    i agree, the slid-over L-plate grip does block the battery access and i accepted that as a trade off for overall simplicity. I did consider leaving the end open so as to not block the battery, and could alwasy make this change should interest warrant it.

    Thanks for your time for these explainations. I always love to know and understand how things are done. Can't wait to see your design. Very good idea to match ridges also. Hope the precision tolerance on this part body to body won't be problem. But I'm sure you have the answer lol.

    mounted; port doors can open, but plate needs to be loosened and rotated to get to battery. L part is intentionally low to not cover ports and to limit overhang

    How might one center the lens over the tripod in the vertical position? I was hoping to be the first customer on this. Looks useless to me.

    Re: JLM L-plate for A7/R

    Best solution yet. Going to have to get one. That l bracket for the Sony 4 adapter from RRS is not working very well as you can't get your fingers to release button to take just the lens off. Here it's totally out of the way.

    For vertical panos you could use a focusing rail and center it

    Re: JLM L-plate for A7/R

    it would require a 4" long L-plate to center the lens in portrait mode and the cantilever would be extreme, compromising the support
    what this solution offers is the ability to quickly change mounts from portrait to landscape and they are quick clamp compatible; hardly useless.

    i could obviously make a 4" long L-plate if you really need that.

    these things are contraptions to some extent, and my way of thinking tries to minimize and simplify and still maintain the functionality

    For me this would work nice on a monopod with long glass like the Minolta 200, Sony 135 which neither have a lens foot

    Re: JLM L-plate for A7/R

    for the hell of it, am making a 4" long L-plate so the lens can be centered, which of course begs the question of whether the base should also slide over, like the A7 L-plate

    Re: JLM L-plate for A7/R

    Might be nice to have the option John. Myself I would just use my focusing rail with clamp on it than just center camera over the pivot for a vertical pano. I still like your short rail so maybe give buyer the option for long or short. I'll take the short one myself. I'll order next week

    I'm really not fan of having to unscrew / rescrew each time to get batteries out. It may finish by ruin the tripod socket screw on the grip :/
    For me such accessorie is 'fix anf forget".

    Re: JLM L-plate for A7/R

    John,
    For the 4" long version, could ther be a small support piece at the top that goes over to meet the camera near the strap lug? That would help the cantilever. Could have a locating pin/bump and a removable screw.

    Re: JLM L-plate for A7/R

    Guy: will i have to rename the short-long version as a shlong?

    dave: to use the camera in portrait with cables, you need to slide the base over for clearance.

    i am refining things a bit

    Kibo: the damn hinged battery door in the grip is such a pig! loosening the grip and rotating a bit seems the best compromise, and you do have two batteries in there

    Re: JLM L-plate for A7/R

    long version for Sony grip completed, ready to ship:
    ports accessible, room for cabling by sliding the base over, captive folding wing screw.

    L-plate is centered on lens and has an index mark, as does the base. to compensate for the extra length, the L-plate is thicker

    you will have to loosen screw and rotate the base a bit to get at the batteries, no tool needed

    John,

    This looks great. How much for the parts to create both configurations of the L-plate (short vertical segment for use when the grip is NOT attached and the long vertical segment for use with the grip installed)?

    the L-plate for the non-grip came is quite different from the grip version, no parts would interchange. you would need one of each

    Re: JLM L-plate for A7/R

    unfortunately not; the battery door is so large and the hinging such that the base cannot move over far enough to clear. you have to loosen the wingscrew a bit and rotate the base out of the way; it does not have to be completely removed.

    Re: JLM L-plate for A7/R

    I love how Arca-compatible plates have evolved over the years.

    For those of us who shoot tethered,
    I wish all plates would have grooves for cables as Foba BALTE/BALPE does:





    except my preference would be for the grooves to run parallel with the length of the camera body and dovetail.

I am looking to order a L-Plate for my Sony A7R and ideally would like to be able to use it in conjunction with the Metabones V3 L-Plate from Hejnar photo. I see that Fred Miranda has had success with the Markins L-Bracket but that one does not allow access for using a cable release when used in the vertical format on a tripod.

    I have also read that the RRS L-Bracket can not be used alongside the Hejnar Metabones L - Bracket.

    Any idea if the JLM L-Bracket (the newer one that allows access to the battery compartment) is able to be used in conjunction with the Hejnar Metabones L-Bracket?

    Ok, thanks so much, any suggestions or advice would be greatly appreciated!
