Join Tim Grey for an in-depth discussion in this video Autofocus and mirrorless cameras, part of Learn Photography: Autofocus.
- So far in this course I've been using a digital SLR…to illustrate some of the concepts related to focus…and auto-focus in photography…and that's because I typically use a digital SLR,…but there are also a new breed of cameras out there,…mirrorless cameras, that include some additional options,…additional features,…and essentially a slightly different approach to auto-focus…compared to what most photographers are familiar with…using a digital SLR.…Digital SLRs primarily use phase detection auto-focus,…which essentially involves taking the actual light…coming through the lens…and comparing two different areas…to figure out whether or not the scene is in focus…and to apply adjustments accordingly.…
Because of the mechanisms involved…that requires the mirror…that is a typical component in an SLR.…One of the things that makes an SLR an actual SLR.…If you're familiar with shooting video…with a digital SLR you might be familiar…with the fact that the focus, the auto-focus, changes.…Instead of phase detection…we're now using contrast detection,…
Photographer and educator Tim Grey explores these questions and more in this exploration of focus and autofocus. And because sharpness isn't everything, Tim also details scenarios where blur can have more impact.
