What is Focus Peaking? A Guide to the Manual Focusing Aid

When using manual focus, it’s difficult to tell exactly where your plane of focus is. It’s possible to make a guess using your eye, but you can still be slightly off and end up with an image that is out of focus. Similar to how histograms take the guesswork out of exposure, focus peaking uses an algorithm and a simple visual aid to help take the guesswork out of manually focusing your lens.

Canon Patent Details Faster Focusing Method for Burst Shooting with DSLRs

As more and more camera manufacturers are taking the mirrorless route to their product lineup, there are still plenty of companies dedicated to producing top-of-the-line DSLRs. And while the mirrorless market is seeing a massive jump in specs with each passing year, the DSLR market is working to keep up with their less mechanical counterparts.

Canon is looking to tackle the growing issue of balancing the focusing capabilities of DSLRs with the mechanical mirror setup that limits what they're currently capable of. And the above patent shows off just how they might achieve that.

A Demo of Split Screen and Microprism Ring Focusing in Old SLRs

If you've never shot with an old manual focus film SLR, you've probably never experienced the joys (and pains) of focusing with a split screen and microprism ring. YouTube user ttcalan created this short video that demonstrates how the system looks and works. He writes,

Focus Peaking Making Its Way onto More Digital Cameras

One of the interesting technologies Sony introduced into its line of NEX mirrorless cameras last year (starting with the NEX-C3) was "focus peaking", a feature from the video recording world that highlights in-focus areas of an image to aid in manual focusing. You know those colorful pixels that image editing programs use to indicate blown out or underexposed areas of photos? It's like that, except for focus. What's awesome is that you can adjust things like focus, focal length, and aperture, and then see the depth of field adjust on your screen in real time. Check out the 10-second video above for a demo.

What it Looks Like to Focus a Rangefinder Camera

If you've never used a rangefinder camera before, this video provides a visual look at how focusing works (a Leica M2 is used).
