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.
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.
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.
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.
Samyang have added another lens to their slowly growing autofocus lineup. They’ve announced a new 35mm f/2.8 FE lens for full frame Sony mirrorless cameras. And, on paper, it looks like it might be able to compete with the Zeiss 35mm f/2.8, but at well under half the price.
Adding to the 14mm f/2.8 FE and 50mm f/1.4 FE, this brings the Samyang autofocus range up to three lenses. Samyang’s range of manual focus lenses has been rather impressive. So, it’s not much of a surprise that they seem to be putting the effort into their autofocus lenses. They’re playing it smart, too. Slowly building up the autofocus lineup, rather than trying to rush a complete range out of the door all at once.
We’ve already seen some of Sony a9’s impressive features in action. We’ve showed you how it focuses and shoots at 20 fps, and now there’s a video that shows its capability of eye-tracking autofocus. It’s pretty accurate and fast, and you can see it work on a person who moves, blinks, turns his head and more. Take a look.
Video responses might be a thing of the past as far as YouTube’s concerned, but that’s not stopping Panasonic. There’s been a bit of talk around the web and YouTube since the Panasonic Lumix GH5’s release about its autofocus system. Well, Panasonic were listening and have responded. Surprisingly, that response comes to us via YouTube.
Lumix Luminary Joseph Linaschke (aka PhotoJoseph) reads the announcement in a video on his YouTube channel. It’s a fairly brief statement, which offers some recommendations for best results. Joseph also got together with fellow YouTuber and filmmaker Max Yuryev to do some comparisons. Two GH5 cameras, with different AF settings.
One of the few advantages to using your camera manufacturer’s software is that they often show which autofocus point was being used when the shot was taken. There is already a plugin which adds this capability to Lightroom, but it hasn’t been updated since 2014. So, much of the today’s camera lineup is not supported.
With the author MIA, frustrated Redditor Joshua Musselwhite (AKA Whizzle) decided to write his own from scratch. As an underwater photographer, it was valuable information for him to have. So, he felt something needed to be done to support newer bodies. Joshua’s plugin is completely free, and at the moment it supports the Nikon D7200 and D800. He’s made the entire thing open source on GitHub, though. So, anybody can add new cameras as they wish.
Samyang brought autofocus into their range of lenses not too long ago with two new Sony E mount lenses. The 14mm f/2.8 and 50mm f/1.4. Now, in a recent interview with Focus Numerique, Samyang head of product planning, Jeong Min Shin says that more are to come.
In the interview, he talked about some of the decisions and compromises that had to be made with the new Sony lenses. But he also suggested that Nikon and Canon autofocus lenses may not be too far away. The story for Fuji and micro four thirds, however, may be another matter.
Have you ever thought about changing your focus setting on your camera? Or perhaps wanted to delve into more of the reasoning behind why you should (in my opinion) consider it?
First and foremost, what you choose to work in and you feel you work best in is entirely your choice, I’m just putting out there what’s worked for me and WHY I think it works for me.
Like many, when I first started taking pictures I started with the camera on auto, then moved to the A/S/P modes on the dial and lastly ended up at manual.
With each progression I found myself delving more and more into the little things that can help you get ahead of your hardware barriers and software limitations so that the only thing between you and a great picture is yourself and not your gear.
The more I transitioned to shallow apertures in my portraiture work the more and more accurate focus became paramount to nailing my shots. As I shoot handheld 99% of the time it’s important to me that the focus on my camera can keep up with the subtle movements of my breathing, swaying and recomposing.
