5D MarkIII - Shutter Hangs on last shot when taking HDR

[ringlis1]

I have been taking some HDR photos and noticed (at times) the shutter will hang closed on the last shot.  As I am taking shots is seems the last shot lags longer and longer.

I returned my first 5D for the same problem and have less than 200 shots on the new one and after about 20 HDR shots it started hanging.  The shots turn out fine.

I am using an SD card so after the shots it takes a few moments to process and write to the card, not sure if this is the cause or not.

Is anyone else having this issue?

Here is link to a quick youtube video I just posted where you can hear the shutter lag.

Canon 5D markIII problem - Shutter hangs	Small | Large

I also sent an email to a canon rep about this issue.  I will post when I get a reply

Seems perfectly normal... the last hanging shot is over exposing by the +2 or +3EV that you chose and hence will keep the shutter open longer. The video shows the last shot with a 1 second shutter speed and it snaps in about 1 second... again seems normal...  Am I missing something?

Absolutely normal.  Look at the LCD, it even tells you - 1/8 for middle, 1/60 for low bracket and 1" for high.

If you change the bracket size you'll notice the speeds change appropriately.

I guess the reason I thought it was a problem, is that I will take several shots of the same area, with no changes to light, exposure, etc.  The last shot hangs longer and longer.

But, I didnt even notice the 1" time for the last shot till you pointed it out, so I will have to go take a few more shots.

The way the camera changes the amount of light for HDR is through shutter speed, so to get that last over-exposed shot it needs to hold it open longer. Try bringing the EV values closer together, like o,-1,+1, then the shutter speeds would be less obviously apart, like, 50th,100th,25th. Doesnt sound like you have a problem, my 60d does the same thing with AEB, but I have to add them into an HDR image myself later :-P id die for a 5dIII!or II for that matter

ROFL this is the funniest thread i have read in a while

I know. He has a 5dIII and is asking THIS question.... hmph, wish I had money

Newbies can buy 5DM3's too, just like 16 year olds given brand new BMWs by their parents when they get their license. Probably not the most ideal way to go, but its their money and time they're expending.

WOW! It is kinda rude to compare someone buying 5D MK III, with 16 year old's getting a brand new BMW from their parents. The guy must have bought it with his hard earned money and has a genuine question ... Show some respect!
Just because someone has question about how shutter works in HDR mode does NOT make a person "newbie" .. for all that you know he could a very accomplished photographer but  he may have never bothered with HDR, so he has a genuine question.
How can you or I judge what is the "ideal way to go" for someone else?

What is wrong with that question? Just because he owns 5D MK III does not mean he needs to know every technicality about HDR photography ... there are plenty of accomplished photographers who never use HDR function.

True true. He did say he didnt notice the 1 second shutter speed. He may not have realized that HDR works by combining 3 exposures.

When I first joined the local photographic society there were a couple of photographers with really fancy equipment (stuff that I could only dream of owning) ... they used to ask some seemingly stupid questions ... and I used to doubt their intelligence and talent (I even made fun of one of them behind their backs), until one day I saw some of their images of football games and birds ... man was I blown away by those pics ... that was almost 6 years ago, if I can take the same kind of quality shots today, I would be might proud.

Agreed, valid question...

Try doing an HDR pointing at the clouds in the sky (lots of light in daylight) and bumping iso to 320 or 400. Speed will be much higher on all 3 shots and it should sound nice.

But agree with you, the first time you use the HDR shot that "hanging" sound sounds weird.

I guess you must have returned your previous model from an online store, otherwise they would have explained it to you.
