Let’s begin first by examining the benefits of shooting 4K at 60fps. Shooting at 60fps simply gives you the ability to slow down footage to half speed so you can get that scene-setting slow-motion effect. Dependent on the interchangeable lens used and User Selected Mode. Dual Pixel CMOS AF (CMOS AF), Contrast AF Most of the camera’s weight sits in the grip, which houses the battery and memory card, but this is countered by the weight of the lens, making the Alpha 6000 well balanced. It’s comfortable to operate one-handed. Top-spec technology and a host of cutting-edge features have given the Alpha 6000 longevity and keeps it competitive even today.

Let’s keep this simple. If you can’t find the details in the manual or online, you can measure this yourself: it’s the distance (in millimetres) between the two horizontal holes and the distance between the two vertical holes. The EOS R's EVF is complemented by a large 3.15-inch vari-angle touchscreen at the rear of the camera, with a decent 2.1-million dot resolution.

Touchscreen for Fast Setup

Cost is important, of course. But it's best to start at the other end and ask, what is it that you want the projector to do? Is it something you want to take out in the garden on summer nights, or is it a projector for a comfy home cinema room? Will it live in darkness, or will you want to use it in brightly lit rooms? What do you want to connect it to? HDR Video modes: 5.3K (16:9) 30, 25, 24 fps 4K (8:7) 30, 25, 24 fps 4K (16:9) 60, 50, 30, 25, 24 fps

A flagship camera needs to be capable of recording great video as well as superb stills, and the Nikon Z9 can deliver 8K video recording from 24p to 60p, or 4K video at 24p up to 120p. With its design focused on dissipating heat, the Z9 can record 8K 30p video for about 125 minutes continuously. Main video resolutions: 6K DCI (17:9) 6000 x 3164 (59.94, 50, 29.97, 25, 24, 23.98fps) raw, 4K DCI (17:9) 4096 x 2160 (59.94, 50, 29.97, 25, 24, 23.98fps) intra or inter frame / light inter frame 4K UHD (16:9) 3840 x 2160 (119.9, 100, 59.94, 50, 29.97, 25, 23.98 fps) intra or inter frame Full HD (16:9) 1920 x 1080 (119.9, 100, 59.94, 50, 29.97, 25, 23.98 fps) intra or inter frame Full HD (16:9) 1920 x 1080 HDR (29.97, 25 fps) inter frame The GH6 – the latest in Panasonic’s much-loved GH line – is a highly capable camera when it comes to video, with a vast array of options and combinations to choose from. For example, it can record 5.7K 30p video in ProRes 422 HQ or ProRes 422, directly onto a CFexpress Type B card.Viewfinder: 0.64-inch type 9,437,184-dot OLED electronic viewfinder, with refresh rate up to 120fps, adjustable magnification up to 0.9x Iris wheel and touchscreen slider for manual iris adjustment on electronically controllable lenses, irisbutton for instant auto iris settings on compatiblelenses. Screen Dimensions Hisense isn’t selling the L9G as a basic projector, but rather as a laser TV with an included ambient-light-rejecting projector screen that’s meant to be permanently installed on your wall. This 100- or 120-inch (varies depending on the model selected) screen will appeal to those who are fussy about image quality, as it will reduce the impact of ambient room lighting on the picture. Sensitivity: Video: ISO 80-102,400 expandable ISO 40-409,600. ISO base in S-Log is ISO 640 but it can be expanded down to ISO 160. Stills: ISO 80-102,400 expandable 40-409,600

Starting with the obvious benefits. Footage shot at 60fps that is slowed to 29.7fps enables you to stretch 1 second of footage over 2 seconds. This is perfect for the visual effect of scene-setting. Think Reservoir Dogs.Maximum continuous shooting rate: 10fps with mechanical or electronic shutter for up to 1000 uncompressed raw files when a CFexpress Type 1 card is used Video specs are similarly outstanding. The EOS R5 can capture 4K footage at a silky smooth 120fps, with the option of shooting raw, while resolution maxes out at a headline-grabbing 8K/30p. Results are gorgeously sharp, while the combination of IBIS with stabilized RF-mount lenses delivers decently smooth handheld shots – plus log files provide incredibly flexible when it comes to color grading.

That said, if you're looking for a big picture then the price differences start to disappear. 4K TVs become very expensive at their largest sizes, and projectors effortlessly deliver bigger images than even the biggest mainstream TVs. If you do have children (or if you’re just slightly clumsy) having the TV on the wall is safer as the set can’t be toppled over and cause an injury. The best 4K cameras will allow you to record bright, sharp footage in a range of scenarios. Resolution is a key benchmark when selecting a video camera – and every model in the buying guide above can capture footage in 4K, with some going up to 6K and even 8K.The Panasonic Lumix LX15 (or LX10 in North America) is a continuation of a popular line of premium compacts, and it punches above its weight for a camera at this price point. Having a 24-72mm equivalent zoom lens is nice, but the f/1.4-2.8 maximum aperture truly puts it a cut above, making the Lx15 much more suitable for low-light work and portraits. In addition, the camera offers 10-bit colour depth and 4:2:2 colour sampling across all recording formats. Sony has introduced new video formats – XAVC S-I 4K (All-Intra) and XAVC HS 4K (Long GOP) – and has made improvements to the XAVC S 4K (Long GOP) format for the a7S III. Viewfinder: 0.5-inch 5.76million-dot OLED electronic viewfinder with 120fps display and 0.76x magnification The Insta360 Pro 2’s new Farsight technology is a 360-degree live monitoring system that promises a high-definition, low-latency video stream for long-distance preview. Most cameras, especially mirrorless and DSLR, will therefore split the bit rate across frames as vbr (variable bit rate). If the bit rate was fixed, then at 30fps 100mb/s, each frame would be 3.3Mbs.
