I have noticed my shutter jerks the camera around when I take pictures, but I have only started noticing it lately. I am wondering if other d70 users experience the same problem.

I am also wondering if Canon users experience this problem.

What about people with more expensive cameras? d2x 1ds 5d?

It's not as much the shutter as it is the mirror. Yes, it affects all SLR-type cameras.

My D70 was just noticeable and my D200 is slighly more.

all have the mirror slap but i notice with some lenses its is MUCH more obvious that others

I.E. i purchaced a Manual focus 55mm f/1.2 - when the it closes down to take the shot
i feel the focus mech. move & obseving the aperture arm it is 'dented' from repeated slaps of the mechinisim (figure a 20yr old lens has been used a fair amount )

Why does it do it more with some lenses than others?

i can only guess but i think that the aperture arm must have to travel much father in low light lenses

or another thought - if the lenses are not aligned with the closing mechanism they will slap & cause damage as well --
possibly on old lenses that were not AI'ed correctly would suffer from this ..

You're going to "feel" it in you hands more with a physically short, light lens. The mirror's mass is small, but it's velocity is pretty high. A large, physically-longer lens will minimize the reaction in the camera. But that does not mean that a longer (flcal length) lens will show less effect on the photos; quite the opposite. The longer focal length lenses show shake from mirror slap much more easily.

The slap on the D70 is like "wzz-zzt"- a bit smoother, compared to my D200, which has a higher FPS. The mirror on the D200 is much faster, and thus giving it a "sma-cracka!" which results in the camera being jolted quicker.

It is annoying, yes, and as mentioned earlier, lens type/shape can affect the sound and effect it has on your shot. I've yet to find any solution other than holding technique. And I'm bad at that.

Mirror slap is unavoidable with any SLR design. That is the big advantage of rangefinder cameras over SLRs, d or otherwise, as rangefinders have no reflex mirror. To compensate for the mirror slap many or perhaps most higher end SLRs have a mirror lock up feature. It will raise the mirror and then allow you to open the shutter after any vibration has died down. In the digital Nikon line this feature starts at the D200 level. It isn't very useful for action photography as the finder will be blacked out, but it's extremely useful in situations where you can take more time, especially with macro shots.

I thought newer DSLRs were incorporating a "delay" feature specifically targetted at allowing these vibrations to die down before opening the shutter??? Am I completely in left field? I thought I'd read this being a feature on the D80?

*EDIT: From Ken Rockwell's D80 review:

"Exposure Delay Mode: The D80 and D200 have an "exposure delay" mode, which is a 400ms delay for shutter release after mirror up. This is D80 Custom Function 31."

Thoughts?

Yes, in situations where timing is not critical, this can be a big benefit. For normal shooting, though, you would not want nearly a half-second of shutter delay. Worse than a 5-year-old P&S! For very long lenses, 400ms is probably not enough, unless the mount is incredibly solid. For those applications, mirror lockup is a better alternative.

my 20d has a seizure every time i press the shutter. It has a bang that sounds throughout a quiet auditorium. Very annoying.

Just some last min ยข2. I have a D2xs and love it. Now mirror lockup and shutter fire sound is like a guillotine going off on by eyeball. Heck i can split logs quieter than this thing fires a photo. I really think that with such a loud sound I'd notice more vibration, but the camera dose not move. Now I have a D70 and a D40 as well and the lighter cameras don't have enough inertia to hold back the mirror reflex. With my 12-24mm and SB-800 the D2xs is upto 9 lbs, and with my 70-200VR its topping ten pounds. This is more than enough weight to stint the mirror movement. If i am on sticks however I will double click the shutter on the M-up frame mode. Once to lift the mirror, then I hold my breath and think solely about one very smooth press. I have also found that his way I can hand hold 24mm shots at 1/2 sec. It's kind of meditative, and puts me at peace in my landscape shots.
