Mirror Lock Up - How useful in handholding shots?

Previously in the film days, only the best Nikon SLR has mirror lock up (MLU) feature. That’s in the Nikon single digit F series. Even the F100 which is considered as the little brother of F5 doesn’t has MLU feature.

So, how useful is MLU?

With the advancement and convenient of digital photography, I can now take shots and experiment shots easily. Nikon now has MLU in their single digit D series and also in the Nikon D200 (D80, D70, D100…etc. all doesn’t have MLU). So, now the question is…how useful is MLU?

Many people have the mis-conception that MLU is only used when you have your camera on tripod. Quite true during the film days where one have to turn a lock manually to lock up the mirror manually, and this required quite big movement and will definitely change/move your subject composition. However, now with better technology and design, Nikon MLU shots can’t be done any easier!

On my Nikon D200, change the drive mode to MLU (there are S, Cs, Ch, Timer…etc. and MLU is on the farthest right on the dial - not seen in the picture below, but is just next to the timer symbol).

When you have set your drive mode to MLU, then the rest is easy. Half press your shutter button to focus, then full press your shutter button to Lock Up the Mirror. Full press again to then take the actual exposure, the mirror will go down after taking the exposure.

So, how does mirror lock up helps in taking photos?

When taking a shot in SLR (Single lens reflex) camera, the reflex mirror will go up, the shutter blade will then open to expose the film/sensor to the light. After that, it shutter blades close and mirror return down.
