Amazon says this is good for 550D.

Does anyone knows if this is the case?

I have had a black spot today and I was frightened. But after some sensor cleanings it went away.

Change.
Video Clip for Norwegian/Greek postpunk group Nekropolis, from the album The New Europeans, Likvidér Records 2010. Shot entirely with the DSLR Canon 550. Edited on Avid Media Composer 4.

A DOF (Depth Of Field) study, using the kit lenses on Canon 550D. Edited and CC on Avid MC4.

Backing up the not so important final edits from MC to 720p.mp4 with Sorenson is awesome. The quality remains intact.

The remote control, I received. It works fine with the T2i.

First time I saw the overheat indicator was with the new cheap battery pack and at 1280x720p/50.
I think this is clearly coming from the unofficial batteries.

George, may I ask what controls are on the remote you purchased?

Can it be used in video mode to start/stop recording or is it only for use with stills?

Here is being describe better.

There is the delay button to start later on.
There is the long exposure setting which I don't understand what it does.
There is the interval setting which is the main one.
There is the (1-399 or infinite if you select --) how many photos setting.
There is the on and off setting for the beep.
And there is the back-light on/off button.

Even on video it shoots photos which is normal as it is a shutter release controller.
It's cheap plastic but it's cheap and it seems to do the job as the Canon 180 euros controller.
So if it brakes (which I don't see how) I can buy other 2 for the same money and I will be left with money for another battery...

I also bought those baterries x2.

They show the battery indicator as the normal one.
Only when in the red mode (ending) it goes off faster than the original.
It lasts more than the original though.
They overheat more than the original.
First time I saw the thermometer it was with the one of those but only on 720p
and after half an hour of continuous shooting,

Not only unofficial batteries. I only have Canon batteries and I've overheated.

May be so Bryan but I haven't yet seen that.
But as the summer is really hot here, I might get the chance to. ;)

Just got the Canon 50mm 1.8 II.
My Raynox 0.66x, I got for the Canon HV30 fits the 50mm 1.8 II wonderfully.
It cuts 2-3 stops but it can be good if you need more field of view with it.
It turns the 50mm 1.8 II to a real 50mm for the 550D.

First quick test with EF 50mm 1.8 II.
