EOS Bodies - For Stills / Re: Underwater Cameras

GoPro seems like an interesting route, does anyone know if it has exposure compensation, and if it shoots raw stills?

EOS Bodies - For Stills / Underwater Cameras

(Apologies if this is in the wrong place, I wasn't sure which area it should go).

I've got a trip to Jamaica coming up in a few months and was looking into underwater options to play around with. This isn't something particularly serious for me, so I'm not looking to spend a ton of money on it (so underwater housings for my 5d3 are out, even rentals are ~$600 for a week).

Does anyone have recommendations for underwater cameras on the cheap side (~$300)

Ideally, I would prefer the following:

- Manual exposure mode (I could also live with Av+exposure compensation)
- RAW support
- 24mm (FF equivalent) on the wide end of the lens

Don't really care if it's Canon or not (the D20 *seems* to shoot raw, but doesn't look like it has manual exposure, and is 28mm on the wide end).

Nice and simple: window light+black foam core for background.

Yes but it sounds like he is comparing the viewfinder square with what is displayed on the LCD screen on the back.  They are two different things not linked least not on the 5D3.

The red AF point markers on the rear LCD are not tied to the point in the viewfinder...though they attempt to show you which AF point was activated during the shot, they are not calibrated to the PD sensor.

So if I mount the body on a tripod, live view and viewfinder focus on different spots even when both for example use the middle AF point? Is that what you are saying, or is one of them just indicating a false AF point position? The middle points are not on the same targets.

The sensor remains in the same spot, framing is therefore the same. I doubt that these two modes have separate AF systems with different AF point locations.

Someone correct me if I'm wrong, but I believe that liveview focusing doesn't use auto focus points at all. The autofocus points are used only for phase detection autofocus, while liveview focusing does contrast detection by actually reading the data off of the sensor itself, rather than making use of the autofocus array.

Check out the packs from f-stop ( They are modular, allowing you to carry both camera equipment and other things (clothes, water, etc...) in the same pack. I took one (the loka model) on a 2 week trek through Peru, worked great.

I've also found getting used to this to be difficult. In particular, I find that when trying to move a number of points to the lleft, I often times end up pressing in the multi controller in (resetting the focus point back to the center one). I'm getting better at not doing this, but still happens quite often. Being able to hold it in (ala joystick) would be great

Software & Accessories / Re: 1d X "silent" mode.
« on: March 12, 2013, 12:23:00 PM »
So in theory, mirror locked up, live view shooting could be a kind of silent mode?

Yes, Live View is quieter than regular shooting.  It also uses an electronic first curtain shutter and that eliminates another  source of vibration - that makes Live View ideal for tripod-mounted shooting of static subjects.

Is this true (electronic first curtain) for other camera models as well (E.g. 5d3), or just the 1dx?

I also found this really annoying when I first got my mk3. Best solution I have found is to change the 'set' button to control ISO, then when you hold in the 'set' button and turn the control dial, you will see the meter change as the ISO changes.

If you are using Lightroom try turning off lens corrections, I noticed something similar at high iso with a 50mm.
