if you absolutely want 1/4000 or even higher shutter speeds.. point the cam at the sun..
Ahhh i also know get alot of flash and high speed sync them =3
Eh TS, my 30D goes up to 1/8000s shutter speed. I've never used 1/8000s. Does that mean I'm using a white elephant? I think I've shot 10x more exposures than you've read photography books.
Please do yourself a favour and really go and understand shutter speed, aperture and ISO. It is not even possible, in bright sunlight, with the ISO at 100, and aperture at f/2 to hit that kind of shutter speed, let alone your own room, or in a shaded area.
As Kit said, just because your speedometer goes up to 220km/h doesn't mean you have to drive at 220km/h to effectively use your car right?
Then u all just have said get those stopepr 5 paint,invest more and etc...
And u though it was me who don't understand apeture,shutter and iso...those are really basic physic stuff which took me 5 mins to understand it all when i was in secondary school science..
So the question now is,if the 1/4000s isn't something whicn can be easily used in a entry level dslr,then why are they incoporating it onto the cam?
If one needs to invest heavily on a entry level dslr to use the very high shutter..then it defeats the purpose of an entry level right?since consumer would rather opt for more professional bodies like d3 or 5d?
their just giving u the option of using 1/4000, and i dont think it cost soooo much more to have a fast shutter(if u consider 1/4000 too fast in the first place). no one is forcing u to use the 1/4000 . the camera is in ur hands.

Or it could be professions that don't need "nice" photos, like investigations or something, where they can use flash and not mind about "ugly" exposure.

On a bright sunny day (no clouds), at ISO 100, if your aperture is about f/1.8, then you'll reach about 1/4000s - just calculate back from the sunny f/16 rule.
Ahh. I tell you when you can use 1/4000. You go out on a sunny day. Aim the camera at the Sun! I ensure you can get it 1/4000.
Man you trying to go against logic here. If the road has a speed limit of 100km/hr, does that mean you cant buy a ferrari? Theres limitation in the physical word that does not allow certain things at certain condition. And just to tell you, its possible to shoot at 1/4000 indoor with a consumer dslr. You just need the right equiment and setting.
Just to say I can obtain 1/8000 if my aperature is 2.8 ISO 200 on a sunny day taking pictures of the Sky

you keep saying you understand, but you really really don't.
when on sunny day (ISO 100, 1/125s, f16) the EV is 15, you want to shoot at 1/4000s, without changing the ISO, you have to change the f stop to f2.8.
so for other lighting condition, you need to change the ISO or the aperture to maintain correct exposure if you want to use 1/4000s. do bear in mind most lighting condition don't permit shooting at 1/4000s.
and stop being so "IRON TEETH."
Do you know how to read (understand) the camera meter? I don't think so..
There is something like this you can find in your view finder. Can be horizontal or vertical depends on the brand of the camera.
If the expoture is right, you will see this.
If the expoture is not enough, you will see something like this (take note of the star which is on the left).
If the expoture is high, you will see something like this (take note of the star which is on the right).
let's say you want to shoot a fish in your fish tank (aquarium) and
(1) you are not using flash.
(2) There is no ambient light (i.e at night and all your room lights are off)
(3) You fixed your zoom (e.g at 50 mm) and your lens has maximum aperture of F2.8.
(4) Your camera is mounted on tripod.
(5) Your fish tank is evenly lit with fish tank lights.
(6) Your fish is moving.
First, you shoot full auto at iso 400 (assuming your camera have no auto iso or you are not using auto iso).
-- your camera metering shows "--'--'--*--'--'--" and shutter speed is 1/30 and aperture value is F4.0.
The picture will be nice. Not too dark and not too bright. But because your fish is
moving, you will see your fish a bit blur.
Second, you shoot manual exposure at iso 400. You want your fish to be sharp in the pic (i.e. stationary). You set your aperture to F4.0, and Shutter speed to 1/120.
-- your camera metering shows "--*--'--"--'--'--" (i.e the amount of light enters the sensor is 2 stops under.)
The picture will be darker than the first one but your fish is more stationary (sharper).
That was how your 1/4000 case happens. There is no enough light for your photos to be properly exposed.
Try to use AV (aperture priority) mode and put the aperture value to the smallest value. (i.e 2.8 or 3.5, the smaller the no, the bigger the apperture and more light goes into the sensor).
And aim at whatever you want to shoot. Read out the shutter speed from the viewfinder. That is the fastest you can go for that scene or subject. If anything faster, your photo will turns out dark. You may wish to push up your iso but there is limitation that your camera can deliver.
hope you understand.

this will be my 1st and last post for this thread.
not that i want to be rude to TS, but it is amazing you guys are even trying to answer his question.
photography makes one sees things from all angles.
Thats why I say he needs a D3. the ISO of 25600 will be a blessing for him. Like this he can use 1/4000 and get smth!
Just getting entertained here hehe.
