The AF features of Fujifilm X-T3 are pretty impressive, judging from the tests so far. But it doesn’t only work well with native lenses: the X-T3 nails focus even with a 600mm lens paired with a Fringer adapter. In this video from Fringer, check out how well the Fujifilm XT-3 performs even with a non-native, adapted telephoto lens.
How far Sony’s autofocus system has evolved in just the past four years
It’s pretty crazy just how quickly mirrorless technology has evolved, especially from Sony. They went from being a somewhat small player in the world of photography to pretty much the dominating force in the mirrorless world, and driving sales away from DSLRs.
But just how far has Sony come in those short few years since the original A7 series? In this video, Dave Dugdale picks up his old Sony A7S and compares it to his current model Sony A7RIII to find out!
GH5 autofocus finally looks fixed with the new 2.3 firmware – maybe
Despite being the rather good video-focused camera that it is, the Panasonic GH5 has been plagued with one big problem. Autofocus. While serious video professionals may say “Bah, who needs autofocus for video?!?!”, plenty of people still want good video AF performance. Many vloggers, for example, shoot with the GH5 and rely on the autofocus to keep up with constant movement in front of the camera.
But has the new 2.3 firmware finally solved the problem of the GH5’s autofocus? Well, Carl Yates at ProAV wanted to find out. So he took a pair of Panasonic GH5 cameras with identical Panasonic 12-35mm f/2.8 lenses, one running the older 2.2 firmware and the other with the new 2.3 firmware to test them side-by-side.
Contrast vs Phase Detection autofocus – What it means and why it matters.
Often, we hear much talk about the advantages and disadvantages of phase detection vs contrast-based autofocus systems. But not everybody knows what that means or why it matters. I had a rough idea, but I didn’t really understand it myself until I watched this video from photographer David Flores for B&H. In it, David explains how each of the two systems work, when it’s best to use one or the other, and how various camera AF systems work today using one or a combination of both methods.
Here’s how to nail focus every time even at f/1.4
Getting precise and sharp focus at f/1.4 isn’t always an easy task, even with autofocus. In this video, Manny Ortiz shares some techniques that help him nail focus every time. He mainly shoots portraits, and he shares with you three tips that will help you get sharp and consistent focus.
How zone focusing will help you to get better street photography
Zone focusing is a term that often seems to confuse people. But if you don’t know what it is, then it’s quite easy to understand why. It’s a common technique for a lot of subjects, and particularly for street photography. I often use it myself because it means I can just raise my camera, take the shot and know it’s in focus where it needs to be.
This video from photographer David Coleman explains exactly what zone focusing is, with several ways to implement it in your shoot workflow. Once mastered, it can be a fantastic way to let you shoot with confidence on the street, just knowing that your subject is in focus.
How DSLR autofocus works and why cross type points are important
For most people, exactly how phase detection autofocus in a DSLR works is a mystery. All we know is that the AF in the camera we’re using either sucks or it’s awesome. While autofocus can indeed suck, it often fails us because we don’t understand it enough to work around its potential pitfalls. This video from ZY Productions demystifies DSLR autofocus and explains why cross type AF points are a big deal.
Watch the new Sony a7R III shoot at 10fps and do eye AF
The new Sony a7R III was announced yesterday and it has introduced some improvements over its predecessor, the a7R II. One of the improvements is 10fps continuous shooting, which doubles the speed of the previous model. Guys from DPReview have published a demo, demonstrating what the new mirrorless camera from Sony is capable of. They’ve tested the continuous shooting, as well as the Eye AF, which also seems to be pretty impressive.
The Nikon D850 has the same autofocus system as the D5 but it’s not as good
We know that the Nikon D850 autofocus system isn’t that great for video. This wasn’t really going to be much of a surprise. But it seems that it’s not as quite good as it could be when it comes to stills, either. The Nikon D850 autofocus is the same as that found in the flagship Nikon D5. And while the D850 does seem to outperform just about every other Nikon out there, it can’t keep up with its big brother.
Matt Granger felt that he was missing more shots with the D850 than he was with his D5. So, he puts the two to the test, side by side in this video. With the assistance of a 4th dan taekwondo black belt subject, Matt sets to work pairing the two off against each other.
4 ways to keep your subject sharp and in focus when shooting video
When you’re a one man video shooting band, keeping your subject sharp and in focus can be a huge pain. If you don’t have a focus puller following you around, or fancy remote control focus systems, it’s a constant struggle. That’s why we often see cameras locked off on tripods and sliders with static subjects that rarely move.
But there are some techniques you can use to keep your subject sharp and in focus when filming solo. Filmmaker Parker Walbeck demonstrates some of these techniques in this recently video. None of these techniques are always perfect, though, and Parker talks about the advantages and disadvantages of each.
