Realistically, you can't expect good photos in the dark.  The best Canon camera for low light is the 1D X, the 5D MK III is 1/2 to 1 stop behind it.
Are you trying to take photos of the screen and have it readable at the same time you get good images of the attendees?
I'd stick to taking photos of the group before lights go down.  You can try it with only light from the screen, but don't depend on it to work out.
 
Here is a example from a local college play from a rehersal.  Actors are in the seating area waiting to appear onstage.  As you see, lighting varies considerably from the front to the back, so a wide angle view like this one does not work well.
This was taken with a Nikon D800 at ISO 12800, f/2.8  .  A Canon 5D Mark III might be just a shade better, and a 1D X will do much better.  Its pretty dark in the seating area, but likely a lot more light than from a screen.


 
I've tried capturing images of the sound and lighting crew at our local high school plays.  Its dark in the theatre, but they do have good enough lighting to see what they are doing.

There is another thread from a person seeing white X's on a black background.  You might compare notes with the poster, however, he did not yet post a image.  It sounds like a similar issue.

EOS Bodies / Re: 7D Dead/Hot Pixel Issues
« on: September 08, 2012, 08:57:29 PM »
I have two 7D's that I have had a few red pixel issues with. In the past they have remapped via the long manual sensor clean method, but now I have found one or two small, white X's on my images with a black/dark background, and I'm wondering what that is. Are they also dead pixels?
Posting the original unmodified would help you get some valid answers.  You may get some guesses based on someones assumption of what you are seeing, but the best answers will come from someone who can see it.
I have a couple of guesses, but i'll refrain from posting uneducated guesses.

EOS Bodies - For Stills / Re: 5D3 Second Curtain Sync - Design Flaw?
« on: September 08, 2012, 08:52:04 PM »
The setup also will require second curtain synch, which I've never used before. 
And, so You posted a subject title that is picked up by search engines, and now spread all over the internet based on your expert finding?

I think the problem is that it spirals out of control quickly by others who seek to outdo the original post.

EOS Bodies / Re: Canon EOS 6D Announcement Soon? [CR1]
« on: September 07, 2012, 10:38:12 PM »

Not to get off topic, but I owned the 5D Mark II and now have a 5D Mark III.  Excactly what does the 5D2 do better?  I cannot possibly think of ONE thing it does better.
I've had both, and I can see the AF points in very low light with the 5D MK II, but not the MK III.  That is a biggie for some, who like to know where they are focusing, otherwise, the 5D MK III is a better camera.

Third Party Manufacturers / Re: A potential Tamron 24-70 problem

As the glue ages, its almost certainly going to happen to many more of the lenses.  Happening early in their life is something to be concerned about.

If zeiss made their lenses with USM AF, I'd never buy a canon lens, Ever. :o

Here you go  :)
 
Zeiss Contax N AF lenses can be converted to AF with Canon.  Zeiss knows very well how to make their lenses AF with Canon, they just have chosen not do do so.

EOS Bodies / Re: 1dmk4 vs 5d3
« on: September 07, 2012, 03:33:43 PM »
I've had the 1D MK III, the 1D MK IV, and the 5D MK III.
The user interface is very similar, and the battery is the same for both 1 series cameras.  The MK IV can be used at ISO 12800 but only if you really have no options.  I did not go over 3200 with my 1D MK III.
The 5D MK III has better AF and low light sensitivity, but not being able to see the tiny AF points in low light somewhat negates the advantage.
I'd say its a toss up, get the one whose features best match your needs.  I had to sell my MK IV due to carpal tunnel, I just could not hold the weight.  I am going in for surgery, so maybe next year, I'll be able to hold the heavier body.

EOS Bodies / Re: Is there a way to confirm focus in Live View
« on: September 07, 2012, 03:18:34 PM »
In my DSLR, the rectangle covering the AF area turns from red to green when focus is achieved.
 I'm not sure about manual focus, but at 10X, your eye is easily as accurate as autofocus, and you can focus on the precise spot you want.

EOS Bodies - For Video / Re: Camera choice mark ii? 7d? wait?
« on: September 06, 2012, 11:31:35 PM »
I have had 1D MK II, 1D MK III, 1D MK IV, 7D, 5D MK II, 5D MK III, and a host of other bodies.  I personally think the FPS thing is overblown,  I usually use single shot, but have also used 10fps and filled up my memory card with thousands of images, which I have to wade thru to find the one I would have likely taken using single shot.
AF accuracy goes to 5D MK II and center point over the 7D, but for focal length limited situations, I'd take my 7D, its good enough, at least as long as their is good light.  It struggles as it gets to be twilight.
Maybe you should consider a rental.  Rent a 1D Mark IV and you will have a excellent body that won't fail you when it counts.  You can fill up that memory card in a few seconds, so take lots and lots of them aling... And make them biguns.

Pricewatch Deals / Re: Win a 5D Mark III Kit from Norman Camera

I've bought several lenses from Norman Camera, I've never had any issues, I'm a big fan of theirs.

Technical Support / Re: Sensor cleaning technique that actually works?
« on: September 06, 2012, 11:15:25 PM »
Cleaning a sensor is something that takes experience.  It took me about 5 tries before I started feeling happy with the results.  I first bought pre-moistened sensor swabs.  They had too much moisture and streaked.  Then I bought dry ones and learned the right amount of eclipse to use.  I also learned to make just one swipe with a swab and toss it.  Using it for a 2nd swipe made the sensor dirtier than when I started.
I now have Canon CPS gold, but have not had to clean my sensor, so my three clean and check coupons are about to expire.

You now have to pay for using EOS Count, while Astrojargon is free and both give the correct results for a 5D Mark II.
A refurbished camera will not read zero, I bought a 7D as well as a 5D MK II grom the Canon refurb store.  Both had a few hundred actuations using eos count on the 7D and Astrojargon on the 5D MK II.

As I recall, their existing 50mm f/1.4 does not gather very good reviews on a FF body, so its time to make something thats better. 
 
Photozone gives it 2-1/2 stars for optical quality, while the much less expensive Canon 50mm f/1.4 gets 3 stars, and it has autofocus as well.
http://www.photozone.de/canon_eos_ff/537-zeiss50f14eosff?start=1
"Some years ago we analyzed the Zeiss Planar T* 50mm f/1.4 on an APS-C DSLR and the results were truly impressive there. However, on a full format DSLR the performance leaves a bit to be desired actually. The lens is capable of delivering great results at medium aperture settings - no doubts - but it disappoints at f/1.4 and f/2 with a rather poor border/corner performance and generally reduced contrast.  Depending on the use-case this may or may not be overly relevant (e.g. portraits) of course. The light falloff is on the high side here but that's a rather normal characteristic for such lenses. Lateral CAs are well controlled and not overly field relevant. The quality of the bokeh is pretty good although the weak contrast may spoil the game at f/1.4.
Just like the rest of its family the Zeiss lens is built to the highest standards. Some users may complain  about the lack of AF but this isn't really a significant flaw for a wide-angle lens. The focus confirmation  is available in the viewfinder (ZE version) and in very critical (close focus) scenes Live-View can give  you the needed guidance. That said, it remains a bit of an anachronism these days. The price level is quite steep so you really have to have a itch for such classic lenses."
