"What shutter speeds need Mirror Up?"


Banning, US
          

What is the range of shutter speeds where the Mirror Up function is needed to control vibration from mirror slap? Does the range vary with the focal length of the lens?

I use a D7000 and a D300. I do mostly landscape and other outdoor shots at f8 to f11 on tripod with a remote cable release and often use a polarizer which cuts down on shutter speed.

I hear that the D7000 generates more mirror slap than the D300?

Thanks,

Jerry

Not my area of expertise, i.e. tripods and landscape. But I think the core danger zone where lockup is especially important is something like 1/60 second down to 1 second - correct?

It will be interesting to hear from others, for example at faster speeds 1/125 and up and/or longer lenses.

I do a lot of bird photography at 500 and 850mm. I am generally, for a perched or walking bird, having good results at 1/800 and 1/1000 second without mirror up and without a remote release. Platform is a mix of tripod, balanced on car window, monopod, or elbows.

I think it was you who shot some plovers in this Forum displayed. I'm trying to find it again to see which lens you used for such clear shot. If you can find these can you please send me the info. mjhach@gmail.com

Thanks.

Or repost them or reference the posting again.

For landscape? All the time, regardless of shutter speed!
I already have my brain engaged on composition, exposure, hyperfocal distance, ND Grads and those I wish could be there with me.

JRP, thanks for your response.

As a general rule I do use mirror up all the time when on the tripod.

However, there are times when the wind is blowing shrubs and nearby trees around and I want to be able to better time a lull in the wind to not have to deal with mirror up if I don't have to.

Jerry

I don't find that using mirror up interferes with spontaneity. When I use MUP (which I do frequently with very long lenses for nesting birds), I tend to lock the mirror up and leave it up waiting for interesting activity to capture before I release the shutter and then lock the mirror up again. I'll just watch the nest without looking through the viewfinder and at times with the assistance of binoculars. Often, MUP will time out and just release on it's own, so I just lock it up again and continue to wait for a good shot.

Yes, I do that occasionally too with some subjects. With others though, I need to see the relationships in the viewfinder.

Thanks!

Somehow that was what I surmised would be the top down answer.

Needed? That depends on focal length, support system and technique. If you're shooting with a 4.5/f2.8 circular fisheye, it probably does not matter - ever - if you use Mup. If you're shooting at 200mm, especially if the lens in question is a big beast such as the 200/f2 or 70-200/f2.8, you would do well to use Mup for the danger zone between about 1/60th and about 1 sec. On the other hand, if you tripod is made out of granite, perhaps it doesn't mean so much. The longer the focal length, the more it magnifies everything - including the subject, your technique and mirror slap. It is definitely possible to see the impact of mirror slap on an 800mm at speeds as high as 1/200th. And it may be higher than that, but I just don't notice since the vast majority of the shots I personally shoot with a big lens at those shutter speeds include a lot of motion anyway.

I have no idea if the D7000 has more mirror slap than a D300. Generally speaking it stands to reason that FX is more susceptible to this than DX, since the mirrors (and shutter curtains) are two and a half times larger.

Brian, thanks for the specifics. Yes, I don't worry about mirror up with my fish eye.

I rarely shoot above 200mm, even though I have lens going to 400mm. You feel that in this range then than 1 sec to 1/60th is about the range that mirror up is a must for sharp photos?

There is an article on dp review inferring that the range is more like 4" to 1/125th. This is far broader than I have read any place else. I use a Gitzo 2541 with a RRS BH-40 and a remote release for landscape.

The idea for using mirror lock-up is that mirror slap causes a small amount of vibration which can be avoided. In the case of fast shutter speeds the need for mirror lockup declines. It is most problematic at shutter speeds under 1/15 sec. Mirror slap settles relatively quickly, so once you get a really long shutter speed it makes relatively little difference. Around 2 seconds is typically long enough that you no longer need mirror lock-up. In both cases, you have a range of situations where mirror slap might have some impact but it is relatively small.

Focal length and specific lens design matter. I have a Tamron 200-500 that needs long lens technique or mirror lockup to avoid vibration even at 1/500 sec or faster as the lens is very long and vibration seems to be magnified. My Nikon 300 f/4 has no such problem even with a 1.7 teleconverter. Long Lens Technique with a hand over the lens barrel is more effective than mirror lockup for wildlife photography since you want to see your subject. It can work for other situations as well, but not as well with really slow shutter speeds where you might move the camera.

The need for mirror lockup is more important with light weight gear, or with setups that have a long light lens without a lens foot. For example, at 200mm an 18-200 is more likely to have a mirror slap issue than a 70-200. Macro photography is another situation where mirror lockup can be very important regardless of focal length or shutter speed. You can often look through the viewfinder and observe vibration caused by mirror slap.

I've used mirror-up whenever I'm on a tripod because it can't hurt... The D7000 shutter is one of the silkiest I've ever felt, so I'd be very surprised if its mirror-slap was worse than any camera, let alone a D300.
