I want to get a universal QR plate, but I have no idea which one to get:
1/4-20
or
3/8-16
I want to get one until I get enough funds for the L-plate...
Thanks!

    I'm using the Manfrotto 3157N plates on both my body and the BG-E2 as well as the collar for my 70-200 with no issues.

    Question is: what is the tripod mount thread diameter for 30D an BG-E2? rolleyes1.gif

    The tripod socket on a 30D is 1/4 in 20 I'm pretty sure....3/8 is a really big bolt.

    Yeah, guy at acratech confirmed that, too:-) thumb.gif

    Oh well, orders have been sent, now we wait...rolleyes1.gif
    I ordered MagFiber NGE2 from Amazon ($375, shipped free, no taxes), and Ultimate Ballhead V2 ($329) and P20 wimberley plate ($52) from Acephoto - it was cheaper to get stuff shipped from East Coast than to pay CA taxes... ne_nau.gif

    Nik, the 3/8-16 is probably not what you want. It's used on some lens
    feet (like the 500mm Canon which has both 1/40-20 and 3/8-16).
    More than likely what you want is 1/4-20 for your camera body.

    If you need it, there are adapters from 3/8-16 to 1/4-20 as well.

    Cheers,

    Like Blurmore said, most 35mm cameras have a 1/4 by 20 female socket on the bottom.

    Some very large lenses and cameras have 3/8 sockets. The Canon 500mm f4 for example has sockets for 3/8 and 1/4 by 20 on its lens foot. I suspect some larger Medium format cameras sport a 3/8th female socket as well.

    Many tripod heads offer both male threads - I use 3/8ths to mate my tripod to my RRS ball head for instance.

    I guess I don't have to worry about 3/8 at all for a foreseeable future mwink.gif

    Yep, it's 1/4", 20 tpi
    Nikolai,

    I have a 20D with BG-E2. It's definitely, definitely a 1/4-inch diameter, 20 threads per inch (1/4", 20 tpi) tripod mount in both the 20D and the BG-E2. So you're going to be fine.

    = Dave


    p.s. It strikes me as odd that all these cameras are made in metric-system countries (esp Japan), yet we have English-threaded tripod mounts?? Would I be correct in assuming that the actual threading is a metric size which (by design) works out to be very, very close to 1/4", 20 tpi?
    Canon EOS 7D ........ 24-105 f/4L | 50 f/1.4 | 70-200 f/2.8L IS + 1.4x II TC ........ 580EX
    Supported by: Benro C-298 Flexpod tripod, MC96 monopod, Induro PHQ1 head
    Also play with: studio strobes, umbrellas, softboxes, ...and a partridge in a pear tree...

    From what I remember, metric and non-metric threads almost never can be compatible. Different angles, or something..
    I think the reason is that photography hardware was originated when English-threads were everywhere, and being a niche industry, they simply didn't have enough compelling reasons to switch to metric.
    Another example would be plumbing in Russia. It's a huge country, as you know, metric system is everywhere. Except plumbing (and photography:-) :D
