    Take a picture of a hummingbird without the wings being blurry?

    a hummingbird flaps its wings 80 times in one sec.

    the fastest a D70 can go is what 1/4000th?

    seems possible.

    Oh ya, the D70 can go 1/8000th of a second! So Im pretty sure it can. Thanks for the reply

    Hello.

    The number of wing beats per second only tells you how many times the wings go up and down in a second. To determine whether your camera can "freeze" the wings you need to know the actual speed at which the wing moves (actually you need to know the fastest speed at which the wing moves, since the speed will not be constant throughout the period of a wing beat. It would probably describe some sort of sinusoidal function).

    Having said that, one would think that 1/8000 is quick enough.:)

    Anyway, you'll find some nice shots here: http://www.pbase.com/canyonlu/hummers

    Perhaps the photographer might give you some pointers if you ask them nice.

    Good luck

    A shutter speed of 1/1000 can freeze a lathe head spinning at 4600 RPM and that's pretty darn fast. :mrgreen:

    Yeah, and that makes a horrible sound, lots of smoke and blood curl. :mrgreen:

    Can others edit my Photos:
    Photos NOT OK to edit
    Having dodged my share of lathe chuck keys, I won't go there. But on the subject of freezing a hummers wings, you will need a good strobe and know how to use it. The cameras shutter is not important. The combo of fast shutter, small aperture and high film speed needed to stop the wings will not lend itself to a great photo. The flash is the only way to get the fine grain and small aperture you want and get enough light to the subject with enough speed to stop motion. The D70 has a fast enough flash sync. to do your hummer good.
