View Full Version : 8000 or Bust

Is it just coincidence that the EOS 1ds Mark II has a top shutter speed of 8000 and costs 8000?
Does anybody really use 8000 as a shutter speed? Or even 4000? Are those speeds really for specialty photography, or am I missing out on something?

The ability to use high shutter speeds is useful if you are working outside on a very sunny day and you don't want to close down the aperture. It's not bad after my third cup of coffee either.

The 1DmkII has 1/8000 as the top shutter speed but it only costs aboue half of $8000 to get it. :D
As for the usefulness of very fast shutter speeds, my take on it is that if you have it, you can use it whenever the need arises for it. If you don't, you can wish real hard for it 'til the cows come hom but you still won't have it.
Say you're at the beach (or somewhere with lots of snow around) on a sunny day (EV=16 at ISO 100) and you want a nice portrait of somebody with a blurred out background. So you decide you want to use the max aperture on your lens, say f/2.8 (AV=3). Well, at that aperture, using ISO 100, you'd need a shutter speed of 1/8000 (TV=13) to get that shot exposed properly. With only 1/4000 sec. you'd need to stop down the aperture to f/4 or, if you want to keep it at f/2.8, use a 2X ND filter.

Well the 20D has this speed & it costs you even LESS to get this shutter speed!!!!!

On a bright sunny day, escpecially with an aperture of 2.8 or below, it is very easy for proper exposure to be achieved with a shutter speed above 1/4000. Highest I've noticed was 1/3200, but that's only because I use an f/4 lens, which would have been a 1/6400 exposure with an f/2.8 lens.

Whenever I use f/2.8 wide open in sunny conditions, the 1/4000 is not enough...
And 77mm ND filters are expensive... and degrade image quality...
Now if you think about using something fast like f/2 or f/1.4... then you'll sure wish you had 1/16000

I've pegged the speedometer on the 1DmkII in the past on a sunny day,. it does happen.
Try using a 200mm f/1.8 wide open outdoors,. I've had to drop to ISO 50 on occasion :)

How's the quality at ISO 50? Why is it a custom function? :confused:

Well that may be 1:1, but it is 16 megapixels for $8000 - that is 2,000:1!
Compared to the 20D, which loses on the shutter speed (8,000 / $1,500) at 5.33:1, but comes out ahead on the megapixel ratio (8.2 MP / $1,500) at 5,466 : 1! :lol: :lol: :lol:
Have Fun,

I've used 1/16,000 a few times on my 1D. I dont mind losing the ability to shoot at such a shutter speed, such as the 1dMKII, but all i ask in return is ISO 50, not expanded.
When i first got my camera i was at a football game talking to a lady about the "extreams" of my new camera, such as 1/500 shutter sync. and the 1/16,000 shutter speed. She said "Yeah, but really...when are you going to ever use that". I agreed with her, but after using the camera for 6 months now, i disagree. There have been times i've used the extreams of this camera, and any other camera that i own, even my rebel 2000's mere 1/2000.

ISO 50 is a custom function because it has an effect on the DR.

I know, but what i want is for it to work nicely. I dont even use ISO 100 on my 1D because of htis.

DR as in digital rebel or something else? :confused:

Why is dynamic range affected by that ISO setting? How bad is it?
