Are you one of those shutterbugs who didn’t know or didn’t bother to use mirror lockup technique? It’s high time you must try this; especially if you are fanatic about sharpness. Although not using it won’t drastically affect your images, it can sometimes do wonders for you, especially when you don’t get the required sharpness even after using a tripod or shutter release.
When you press the shutter button, the mirror of your camera flips to allow light into the sensor. This flipping causes vibration thereby decreasing the image quality. The best way to handle this issue is to lock the mirror. This is mostly a manual setting that you can find our under the custom function setting (C.Fn).
Although mirror lockup is a great tool, it has one major disadvantage. Once you lock the mirror, you won’t be able to through the viewfinder. If you haven’t tried using mirror lockup, try it and share your experiences with me.
