by 7 Comments

Three weeks ago, we told you about the Samsung Galaxy S20 launch. Not all is bright in S20land though. Over those three weeks, quite a few users have been reporting on issues with the S20’s camera. The issues seem to mostly affect the high-end model, the Galaxy S20 Ultra.

The S20 Ultra boasts a 108-Megapixel sensor on the main camera, and a 48-Megapixels sensor on the 100x zoom camera. This phone, and the tech inside it, reecived some great hype. On paper, they are indeed extremely impressive, but twitter seems to be disappointed with the real-life results.

In this video, photographer Pierre Lambert looks at what back button focus is, and when it might be beneficial to use it. He also looks at when it may be more beneficial to do things the old fashioned way with a half press of the shutter.

by 3 Comments

New cameras get a lot of hassle over their autofocus systems. Either it doesn’t have Eye AF, or it isn’t dual pixel or it’s not phase detection. But what do all of these things mean? And I don’t just mean what are the technical differences, but how and why does this matter in the real world? And to whom does it matter?

That’s what this video from Gerald Undone covers, in probably the most unbiased way I’ve ever seen. Autofocus technology is evolving rapidly, and he covers just about all of it. He explains how they work, the pros and cons of each, when the system your camera uses matters and when it probably doesn’t.
