Compared to a few years ago, the range of video cameras available to buy has shrunk to all but nothing. With the popularity of cell phones, the manufacturers have cut their selections down, focusing on a few models aimed at those who want more than a cell phone can offer.
Camcorders are designed to give you everything you need to take amazing videos. This makes them lightweight, extremely portable, and perfect for people who want to focus strictly on videography and not photography.
Some experimental cameras, for example the planar Fourier capture array (PFCA), do not require focusing to allow them to take pictures. In conventional digital photography, lenses or mirrors map all of the light originating from a single point of an in-focus object to a single point at the sensor plane. Each pixel thus relates an independent piece of information about the far-away scene. In contrast, a PFCA does not have a lens or mirror, but each pixel has an idiosyncratic pair of diffraction gratings above it, allowing each pixel to likewise relate an independent piece of information (specifically, one component of the 2D Fourier transform) about the far-away scene. Together, complete scene information is captured and images can be reconstructed by computation.
Hi, great info. Going on Safari in June. I have a 10 yr old Canon HD camcorder, was great when it came out – one of the first HD camcorders. its ok, but thinking of replacing, its just a pain in the …, only uses FireWire, awkward to hold, etc… Will have a Canon 70D DSLR on the trip as well…would one of these camcorders shoot better video than this DSLR? Wondering based on an answer you had below noting the sensor size, and the 70D is a full frame sensor…Thanks!

One other option, though it’s a really tricky one, is to hack a camera. CHDK is a homebrew firmware that you can load on many Canon compact cameras that will give you access to a great many more features, and may allow you to work around the 30 minute limit

The Canon also captured decent stereo sound, but picked up much more of the ambient noise, which sometimes overwhelmed the subject. This effect was even more extreme in the Sony, which was much more sensitive to noise such as aeroplanes flying overhead.
Travel vloggers want light setups with excellent image quality to show amazing locations. Beauty vloggers need sharp optics, excellent autofocus, and high-quality audio. Family vloggers want highly portable cameras that can withstand the demands of a rough and tumble bunch of kids and all the chaos and fun that they bring.
Special systems, like those used for scientific research, e.g. in an observatory or satellite or spaceprobe, or in artificial intelligence and robotics research. Such cameras are often tuned for non-visible radiation for infrared photography (for night vision and heat sensing) or X-ray (for medical use).
In 1080p/60 AVCHD mode with the supplied battery, the Panasonic V720 has a battery-life rating of about 1.5 hours when recording continuously (no stopping and starting or zooming) and 45 mins. of “real world” usage (stopping/starting/zooming). There’s a longer-life battery pack sold separately (around $130 — the VW-VBT380) that boosts recording times up to 3 hours continuous / 1.5 hours real world.
The main difference between the W850 and the V750 is the addition of the back-facing “selfie” camera on the W850. Otherwise, I think they are mostly identical. The X920 uses a different image capture system, with three separate sensors that capture red, green and blue. This generally means better quality and more color detail.
The ability to capture 5.1-channel sound definitely added to the realism of the video. Even when this was mixed down to 2-channel stereo sound (5.1-channel recording is not supported in MP4 recording mode) it had more presence than the other video cameras, with better stereo separation and audio cues to let you know where sounds were coming from. So at that third-grade play, you’ll be recording what’s being said on stage, rather than the murmuring of appreciative audiences around you.
Most camera phones are simpler than separate digital cameras. Their usual fixed-focus lenses and smaller sensors limit their performance in poor lighting. Lacking a physical shutter, some have a long shutter lag. Photoflash is typically provided by an LED source which illuminates less intensely over a much longer exposure time than a bright and near-instantaneous flash strobe. Optical zoom[2] and tripod screws are rare and none has a hot shoe for attaching an external flash. Some also lack a USB connection or a removable memory card. Most have Bluetooth and WiFi, and can make geotagged photographs. Some of the more expensive camera phones have only a few of these technical disadvantages, but with bigger image sensors (a few are up to 1″), their capabilities approach those of low-end point-and-shoot cameras. In the smartphone era, the steady sales increase of camera phones caused point-and-shoot camera sales to peak about 2010 and decline thereafter. Most model lines improve their cameras every year or two.
If you’re not familiar with the term, the mirror that mirrorless cameras lack is the one that directs light to an optical viewfinder from the lens. SLRs, of course, still offer that. Getting rid of the mirror box allows for a slimmer design with fewer moving parts, as well as more accurate autofocus. And, with the latest spate of models, autofocus is fast. So fast that you won’t miss shooting with an SLR.
You may not think that you’ll be doing a lot of nighttime shooting, but it doesn’t take much of a dip in light levels for low-light performance to become important. Recording a birthday party at night, indoors? Or a family dinner? Off trick or treating? Or the ubiquitous school play? In all these cases, you need a video camera that will still deliver smooth motion and clean footage, where you can see all the details of what’s going on around you.
We were able to cut the Canon R62, RF52, R60 and R50 based on them being all but identical to the R500 except costing more for having built-in storage, and in the case of the the latter two, Wi-Fi.When you can pick up a 32GB SD card for under $20, the $100 extra cost just doesn’t make sense: it is cheaper to buy the no-memory model and a handful of SD cards. This same logic also eliminated models like the now-discontinued $850 Sony HDR-PJ430V and HDR-CX290, and the HDR-PJ380, all of which had cheaper variants without built-in memory.
In 2000, Sharp introduced the world’s first digital camera phone, the J-SH04 J-Phone, in Japan.[50] By the mid-2000s, higher-end cell phones had an integrated digital camera. By the beginning of the 2010s, almost all smartphones had an integrated digital camera.
Camcorders have three major components: lens, imager and recorder. The lens gathers light, focusing it on the imager. The imager (usually a CCD or CMOS sensor; earlier models used vidicon tubes) converts incident light into an electrical signal. The recorder converts the electrical signal to video, encoding it in a storable form. The lens and imager comprise the “camera” section.
The very large sensor these backs use leads to enormous image sizes. For example, Phase One’s P45 39 MP image back creates a single TIFF image of size up to 224.6 MB, and even greater pixel counts are available. Medium format digitals such as this are geared more towards studio and portrait photography than their smaller DSLR counterparts; the ISO speed in particular tends to have a maximum of 400, versus 6400 for some DSLR cameras. (Canon EOS-1D Mark IV and Nikon D3S have ISO 12800 plus Hi-3 ISO 102400 with the Canon EOS-1Dx’s ISO of 204800)
For a long time the premium models sported 1/1.7-inch class sensors, which offered modest advantages over the more common 1/2.3-inch type found in entry-level cameras and premium smartphones. Sony changed that in 2013 with its revolutionary RX100, which brought the 1-inch sensor class into the spotlight.
Other cameras use wireless connections, via Bluetooth or IEEE 802.11 Wi-Fi, such as the Kodak EasyShare One. Wi-Fi integrated Memory cards (SDHC, SDXC) can transmit stored images, video and other files to computers or smartphones. Mobile operating systems such as Android allow automatic upload and backup or sharing of images over Wi-Fi to photo sharing and cloud services.

Unfortunately, as for the video bitrate, I don’t really know enough to make a hard call. I’m betting 24 Mbps will be just fine and keep in mind that you can always convert it to a lower bitrate, but not the other way around. I believe (though I could be wrong) that the 35 Mbps is linked to shooting at 60p, where 24 Mbps is at 24p. 60p will have much smoother motion, but 24p is more “cinematic” and generally how we’re used to seeing movies and TV shot. So video shot at 60p sometimes looks a bit “off” if you’re not used to it.
