Is Mirror lockup not available with the new D80? I ask because I've seen examples in photo magazines where the the mirror slap caused enough camera movement to affect the picture (more likely with telephoto shots I imagine). In that case, is the D200 the camera that does have ML?
If this is the case, are any tricks available to get around the lack of ML in the D80, short of getting a D200?
The D80 does NOT have mirror lockup. There is an option called exposure delay you can activate via the menus. It adds a 0.4 second delay between raising the mirror add releasing the shutter to reduce the effect of mirror slap.
by the time I wrot up my response to randy, tweek had already responded above.
I believe that some reviews or previews of the d80 were listing exposure delay as mentioned by randy. I believe that I'll be looking at the online d80 manual on pg 106 to clarify. Apologies if I've caused any confusion.
The D80 has a mirror/shutter delay mode where the shutter opens 0.4 seconds after the mirror is completely up (as opposed to normally opening as soon as the mirror is out of the way). As far as I know, this is the best you'll get in relation to true mirror lockup.
From some threads I have read in the past, if you think that the mirror slap will cause some movement, and the depending on the exposure time you are looking at using, one could hold a black card in front of the lens for a brief period (maybe 1/2 sec - 1 second) to eliminate the effect on the image. The brief period the card is in front of the lens should not effect the final image to any degree if the exposure is of decent duration.
I think the Exposure Delay on the D80 will reduce vibration from mirror slap. Some have questioned whether 0.4 seconds is enough, so maybe MLU is better. This may be true, but until someone does some comparison tests between the D80 and D200 we'll never know. Anyone got both and willing to test?
Exposure Delay may offer some benefit that MLU doesn't have, i.e., when shooting at slower shutter speeds without a tripod. Once again, we won't know this until someone does some comparison tests (I'll try to give this a try this weekend and post the results).
My dream camera would have an adjustable Exposure Delay and MLU. Nikon, are you listening?
P.S. I think when the other poster was referring to using a card in front of the lens, he had very long exposures in mind (at least 10 seconds). However I think mirror slap will have very little practical effect on any shot that has a long enough exposure to allow using the card technique.

I think you're quite right Mike - from what I've read elsewhere mirror slap is really only an issue for exposures between approx 1/30 sec and 2 seconds. (You might recall an article showing night shots with wavy lines of diminishing amplitude traced by a boat sailing past with a light on deck - it demonstrated the issue really nicely, and I guess if one knows horizontal speed of the light point it should be easy to calculate the horizontal time scale and thus the time it actually takes for the vibes to stop! I can't remember where I saw it though, but if I can find it I'll post!) That was however based on 35mm film SLR which has a bigger heavier mirror - almost certain to cause more vibration than on a D80 where the mirror is not only lighter but probably also better balanced and damped. Maybe the 0.4 sec delay is enough? It seems unlikely Nikon would have set this delay arbitrarily. I'd be very interested to see the results of any comparative testing as I do a fair amount of available light and landscapes in exactly that shutter speed range, and I'm planning to order my D80 next week.
BTW, thanks for all your helpful posts on the D80!
