    Just got this new camera and I have to say its awesome. I'm wanting to do a documentary and do some shallow depth of field stuff. I'd like my subject in focus and the background slightly blurred. Does anyone have any tips to achieve this?

    Without getting all technical, the long & the short of it is that depth of field gets smaller the more you zoom in and the more you can close your iris. Back away from your subject so that you have to zoom in pretty far to frame him. Obviously you'll need a good tripod here. Light him well so that you can close your iris a stop or 2.

    That's the short answer. If you want more in depth than that lemme know & I'll get all textbook on you.

    Sweet camera, btw. I'm hoping to get one this fall.

    Zoom in as far as your optical zoom can go and open up the aperture a lot.

    Does that work?

    If you can adjust the aperture manually, set it to the lowest number (widest iris). Because of this you'll also get more light in your lens, so your camera will use a faster shutter speed. If your scene is too bright, you may not be able to choose a low aperture.


    So who is right, PegasusMedia or me? :)

    edit: my god, am I slow..

    You want to open up the Aperture a lot, and use some ND filters if it's really bright I believe.


    Why are you slow?

    Oops

    Yes you guys are right. I had the aperture thing backwards.

    Thanks!

    Getting coffee now....Ahhh that's better!

    When I started typing that post, you hadn't posted yet, so it took me at least 15 minutes. ;) I was distracted by other stuff or something.

    haha I understand, as it turns out, I just read an article about this today so I can't wait to go out and try it today.

    M2 Adaptor

    Here is another (not cheap) solution - the M2 adaptor

    I have one that I am using with my HDR-FX1. The results are fantastic.

    I suppose you can't go handheld with that unit attached? How much does something like that go for?

    With a homebrew (or pro) stedicam rig, you /can/, however, with such a short sweet spot with the focus, it will be difficult. We are experimenting on that very problem now. The range really depends on what lens you use. We did some tests with a dolly and they were very not bad. It the real world, the sequence would use a combination of shots with and without the adaptor.

    The rig that I went for included the rail system ($1,295.00), but the rails are very nice.

    The adaptor by itself is $550.00 + $90 for a the lens mount (nikon, canon, etc)

    They also have a DIY kit for $45 that includes the ground glass, but the 72mm Achromatic lens will set you back $395, so unless you have a ton of macros laying around, the prebuilt adaptor is the way to go.

    Also check out this link if you wanna go total home brew. I started down this path first -

    Right on. This is the route I'd suggest. I did this with an XL2 and the results are quite nice.

    Thanks everyone for your input. It's working a treat. A film lens adapter is the dream, but for now, it's working fine.

    Thanks again.

    Not sure.

    They presented at NAB, though only with a few "non-working" (i.e. hollow plastic) prototypes. I'm still not sure what to think of the whole thing...

    EDIT: looks like they've updated their site with some more detailed mockups.

    My favorite uber device to never come to market has been the Kinetta I just hope we see the RED camera become a reality.
