    camera question for you guys

    As long as she doesn't return the sentiment and buy you an emerald green crocodile handbag for your next birthday ;)

    compact frame, full sensor, a big deal?

    Depth of field is shallower with a bigger sensor - this is one of the major reasons for the sudden popularity of the 5DMkII for video - you can get that "sexy" out-of-focus background when doing close-ups of people, etc. A bigger sensor doesn't necessarily yield "better quality" since they use...

    compact frame, full sensor, a big deal?

    The hyper-wide angle is indeed the limitation with most video cameras. Apart from a few minor technical issues, I believe there's actually a very valid reason for this - hyper-wide video just looks bloody awful unless you really know what you're doing and want to use the effect deliberately :)...

    camera question for you guys

    Yes- you'd need flash to "fill in" the face (or a silvered reflector, but that's not so easy ;)). As Chris said - one of the auto mode on that camera should help - this is a common scenario. The keyword you should look for in the manual is "backlit" - that's what you are attempting here - a...

    compact frame, full sensor, a big deal?

    Mmmm.... why this insistence on using a stills camera for video? If you want the best video, why not use a video camera? Dollar for dollar (and gram for gram), a dedicated camcorder from Sony et al. will comfortably outperform a stills camera "that can also do video clips".

    Found My Distro Board Finally... Powerhungrysystems.com

    because gold doesn't tarnish/oxidize, so it's the best way to make low-resistance sliding/switching contacts - like bullet connectors that are gold plated. EDIT: typo - reversed my intended meaning :)

    Found My Distro Board Finally... Powerhungrysystems.com

    That eye-wateringly expensive PDB also introduces 16 potential points of failure - and the way it's arranged, you can't even heat-shrink the bullets together. And the point of gold-plating the whole thing is what, exactly? Sorry, but to my mind, the ultimate example of a (poor) solution looking...

    What happened to Freefly Radian?

    Released AFAIK - their forum says all pre-orders have shipped.

    Why doesn't the math for prop size and cell count match add up in Ecalc

    I can't be sure, and the author may have fixed it - but I do remember encountering a possible bug when specifying a custom battery pack. Try choosing a standard battery pack that's close to the spec you've entered, just to make sure the figures don't change wildly.

    Overlapping Propeller Designs

    ah - now I understand ;) You mentioned vertical CG placement in your DIYD write-up - that's an area of great interest to me. Hanging the camera under the centre of the disc is clearly a practical necessity rather than an optimum solution. The ideal is to have the CG coincident with the centre...

    compact frame, full sensor, a big deal?

    Unfortunately Canon plays the "feature spread" game very effectively - if you want 1080/60P, it's available from Canon - it just costs more. :)

    Overlapping Propeller Designs

    Sorry - still need to know (from the earlier thread and the DIYD write-up) - what is "D/L"? Re: the "efficiency loss" with a coax setup - you really need to test with higher-pitch props on the bottom. Of course, then you have test to different combinations of pitch, different profiles...

    Hamer X4 - Ultimate Kopter for Filming Industry

    Rob - interesting stuff - but I don't think it's fair to divert this thread with this material - perhaps start a new thread to disclose and discuss this very interesting research?

    Hamer X4 - Ultimate Kopter for Filming Industry

    Ok, just a communication breakdown - the implication was that the video contained something relevant to the discussion :) Not sure what you think I'm being "rather critical" of, Denny - and as to "stunning" you all, I don't feel the need to prove anything to anyone in that way - should I? ;)

    compact frame, full sensor, a big deal?

    This RX1 is not really relevant to AP, I think - it's a close-quarters photojournalism tool. No wired/wireless remote control (but a threaded mechanical release by the look of it) and only HDMI out. More interesting IMO is the NEX-6 - if they publish the specs for the wi-fi link. The rate at...

    Hamer X4 - Ultimate Kopter for Filming Industry

    Well that was a waste of 6:48-worth of my morning ;) - nothing about AP in there! I assume you just meant "single rotor"?

    Why doesn't the math for prop size and cell count match add up in Ecalc

    Impossible to say without seeing exactly what you are doing - try posting some screenshots. I've found eCalc to be very good - but it does need to be understood and set correctly.

    S800 Arm's carbon fiber wrapped

    It should be perfectly obvious, Denny, that I'm poking and prodding at the Zenmuse and how it works precisely because I don't know. Not having one in front of me (and not being rich enough to buy one just to look) I can only rely on information gathered here from owners, combining that with what...

    Neills DIY Gimbal Design

    Interesting - of course, they should be mounted in compression - but since neither side of the mount is "fixed" then I think that normal rules don't necessarily apply. Zenmuse certainly breaks the rules, being in tension and also using 12 of them (which is probably way different to their...
