The camera focuses (unless you have selected manual focus, MF).Normally, when making an exposure with the mechanical shutter, what happens when you press the shutter is this: I'll get back to all of this in the article.Īs said initially, the electronic shutter is interesting because it is totally silent. It also does not work with a flash, and cannot be used with high ISO or a very slow shutter speed. On the downside, the electronic shutter suffers from heavy rolling shutter artefacts, making it virtually unusable with moving subjects, or with a long lens. It probably also has a quicker response time, however, I have not tested if this is actually a fact. The electronic shutter has the advantage of being silent, of course, since no mechanical shutter is moving at all. Probably, these cameras share some sensor components. It's not correct to say that this is a new feature, though, as the Panasonic G5, launched some months earlier, also has an electronic shutter. One of the interesting new features of the Panasonic GH3 (my review) is the possibility to use an electronic shutter.
