4k, down sampled to 1080p, looks better than 1080p captured on a higher resolution sensor, from which rows of pixels must be binned, leaving moiré and other artifacts. 4k also permits cropping in...

Does the Hero 7 Black stabilization work in-camera? Or, as in the case of the Insta360 products, must one import shaky footage into special PC software and slowly render each file, one by one, to...

People in a Fuji forum might offer more informed comment.  Does that camera in fact record video at the same bitrate, regardless of frame rate?  If so, 50p would offer less data per frame, yet ...

No point in altering the frame rate if it entails de-synchronization of the audio or binning frames.  Video shot originally in 24p might look smoother, but mainly because the shutter time will be ...

You might give 60fps a try.  But greater smoothness would be perceptible mainly if, when editing, you slow the playback below 1.0x. Other options: slower panning, wider lens, or a liquid head ...

There is a big price difference between this product and other motorized sliders. It would be nice, however, if for only a few dollars more, one could get a product with a more consistent or...

Gaps between the teeth of the blue plastic track occur within each rail section, not just at the juncture between the sections. This is because the track component is extruded or molded in strips...

The ax53's 1/2.5" sensor outperforms the 1/2.3" sensor of its predecessor ax33 because it is optimized for 4k.  Less moiré, etc.  Low light results are tangibly (but not dramatically) better. The ...

Insta360 sells cameras that shoot at very, very wide angles.  Since it is of little use to watch video in 360-degree "Google Street View" mode (which view does one pick?), it is preferable to ...

An impressive number of replies to a query about a camcorder few respondents have actually used! The AX53 is not tiny. But it weighs less than any other device that offers an internal gimbal and ...

Ho ho ho! There will be no LX7ii.  Too bad.  Yet there is a basis to argue that the LX7 (introduced in 2012) had qualities that surpassed the LX100 (2014) in various ways: (1) More compact.  It really ...

Are you unaware that online there are 360 degree shots of tens of thousands of the whole length of streets and roads in multiple countries around the world.  Google uses an algorithm to blur ...

Looks a little expensive. For $14, you could buy a kit of action camera accessories, including a harness and a whole lot else. Voilá : https://www.amazon.com/Black-Common-Outdoor-Session5-DBPOWER/d ...

I don't think an auxiliary / external gimbal will work well for long zoom. Finding your distant subject will be difficult, no matter what the camera, if you are aiming long and the sunlight make ...

I doubt anyone in this forum has "exact knowledge" of all high end cameras' slo-mo performance. There are a lot of second hand impressions. It is also the sort of query that inspires click-bait ...

All m4/3 cameras I know of, including the OM-D E-M10 III and GH5, use contrast detect AF, which gets dodgy in low light or where contrasts are weak.  CDAF also fouls if there are bright lights in ...

SSDs can accelerate operating system and software operations. But the most intense and repetitive activity needs relatively little space, less than 8GB for ordinary functions. More SSD space...

Two dead SSDs? What brand and model? At what age? Please don't simply start an urban legend. A few details, please. smcleod.net reports a very low failure rate in rather large SSD samples.

RB: "ISO changes the lightness of the final image but it doesn’t change the fundamental sensitivity of your sensor."

How does it raise the lightness without greater sensitivity to light, other...

PD 15 and 16 both have a built-in audio sync tool, as explained in this video by an aging biker. PD has featured PIP / split screen for a long time. If the basic white balance, hue, saturation, and ...
