New Tech Totally Eliminates Zoom and AF Noise from Video Soundtracks on the Fly

DSLRs and Compact System Cameras are becoming increasingly capable video capture devices in addition to being solid still shooters. But when it comes time to focus or zoom using the lens' or camera's built-in motor, you're often left with glaringly obvious noise on your soundtrack.

So far manufacturers have tackled this problem by introducing silent focusing motor lenses, but one group of engineers is taking a firmware-based approach that seems to work just as well (if not better) and might someday soon do away with zoom and AF noise entirely.

This Handheld Camera Captures Sound In Addition to Light

You've probably heard of cameras that can detect wavelengths of light that human eyes can't, and also cameras that can detect heat in a scene, but have you ever heard of one that can capture sound? That's right: scientists at the Korea Advanced Institute of Science and Technology have created a portable sound camera that's sensitive to sound waves.

Canon 6D and 5DMk3 Noise Comparison for High-ISO Long Exposures

Astrophotography enthusiast Don Marcotte wanted to find out whether the Canon 6D or Canon 5D Mark III was more suitable for his area of photography, so he pitted the two cameras against one another in a few noise tests at his local camera store. He simply shot long exposures without any light (the cap was on) in order to see how much noise would show up in the frame.

Nikon D3200 Sample Images Show Noisy Low-Light Performance

The first sample images of the Nikon D3200 have just come out of Nikon France; and although they look great for the most part, the one low-light image confirms suspicions that Nikon may have gone too far putting 24.2-megapixels in the camera. More noticeable on the full-resolution photographs, you can tell that once the ISO is cranked up to about 1600, noise begins to play a significant role.

Freeze Your Camera for Less Noise

Last Friday an anonymous poster on the photography board of 4chan sparked a discussion that rippled into the blogosphere after freezing their camera to see whether ISO performance improves at lower temperatures.
