Film speed Traditionally used to “tell the camera” the film speed of the selected film on film cameras, film speed numbers are employed on modern digital cameras as an indication of the system’s gain from light to numerical output and to control the automatic exposure system. Film speed is usually measured via the ISO system. The higher the film speed number the greater the film sensitivity to light, whereas with a lower number, the film is less sensitive to light. A correct combination of film speed, aperture, and shutter speed leads to an image that is neither too dark nor too light, hence it is ‘correctly exposed’, indicated by a centered meter.
Unfortunately, I don’t know enough about the X920 to comment off hand, but Reviewed.com has Reviewed both it at the Panasonic W850, which I believe has the same sensor as the V750/770, but with a few more bells and whistles (I might be wrong on that, these things get very confusing). So you can check out a bit of a comparison between the two by looking at the two reviews.
“Ahah!” I hear you cry. “If my cell phone isn’t good enough, why not use a DSLR or mirrorless camera to shoot video?” DSLR and mirrorless cameras are excellent devices for taking photos and video. If you want to do both, then they are a great hybrid option. However, they can involve serious compromises when it comes to audio and video. In particular, dedicated video cameras offer major advantages for sound, focusing, zoom, and clip length.
I would agree that the Sony would be overkill, and the issue with the GoPro is also that since it’s such a wide-angle lens, you’d have to have it right in the speaker’s face for the entire duration, rather than at the back of the room.

If you’re buying your first DSLR, it makes sense to buy it as a kit, which generally includes the camera body along with an 18-55mm lens. Often referred to as a ‘kit’ lens, this covers a pretty broad zoom range, perfect for everything from landscapes to portraits, but that’s just the start. 
When photographing rapidly moving objects, the use of a focal-plane shutter can produce some unexpected effects, since the film closest to the start position of the curtains is exposed earlier than the film closest to the end position. Typically this can result in a moving object leaving a slanting image. The direction of the slant depends on the direction the shutter curtains run in (noting also that as in all cameras the image is inverted and reversed by the lens, i.e. “top-left” is at the bottom right of the sensor as seen by a photographer behind the camera).
Agreed. I just got back from a trip with the a6300 and was infinitely impressed with its portability and quality – and cheaper to rent, to boot. Looking forward to trying the a6500 (https://www.borrowlenses.com/product/Sony-a6500).

Due to the optical properties of photographic lenses, only objects within a limited range of distances from the camera will be reproduced clearly. The process of adjusting this range is known as changing the camera’s focus. There are various ways of focusing a camera accurately. The simplest cameras have fixed focus and use a small aperture and wide-angle lens to ensure that everything within a certain range of distance from the lens, usually around 3 metres (10 ft) to infinity, is in reasonable focus. Fixed focus cameras are usually inexpensive types, such as single-use cameras. The camera can also have a limited focusing range or scale-focus that is indicated on the camera body. The user will guess or calculate the distance to the subject and adjust the focus accordingly. On some cameras this is indicated by symbols (head-and-shoulders; two people standing upright; one tree; mountains).
Price. Price is an important point to consider when choosing a DSLR because your camera body isn’t the only thing you will need to buy. Along with lenses you may also want to purchase things like filters, bags, cleaning supplies, and a tripod. This can add up quickly! Be sure to leave some room in your budget for accessories.
Sensor: APS-C CMOS | Megapixels: 24.2MP | Autofocus: 45-point AF, 45 cross-type | Screen type: 3-inch articulating touchscreen, 1,040,000 dots | Continuous shooting speed: 6fps | Movies: 1080p | User level: Beginner/enthusiast
The $600 Panasonic HC-V770K has the best video, audio, and stabilization quality out of all the cameras available. We like its clear, bright video in low light, and the audio quality from the built-in microphone (as well as the ability to connect an external microphone). In situations where other camcorders capture grainy video, the V770K’s video is still clean and sharp.
In September 2014 Panasonic announced and claimed 4K Ultra HD Camcorder HC-X1000E as the first conventional camcorder design that can capture up to 60fps at 150 Mbit/s or alternatively standard HD recording at up to 200 Mbit/s in ALL-I mode with MP4, MOV and AVCHD formats all offered depending on the resolution and frame rate. With use 1/2.3″ small sensor as commonly is used by bridge cameras, the camcorder has 20x optical zoom in a compact body with dual XLR audio inputs, Internal ND filters and separate control rings for focus, iris and zoom. In HD capture, the camcorder get benefit to reduce noises of small sensor by in-camera downscaling of the 4K image to HD.[8]
While the main specification of the OM-D E-M10 Mark III doesn’t offer a huge upgrade from the Mark II, Olympus has refined and tweaked one of our favorite mirrorless cameras to make it an even more tempting proposition for new users and enthusiasts alike. Some will criticise the smaller Micro Four Thirds sensor format (roughly half the area of APS-C) but the effect on image quality is minor and it means that the lenses are as compact and lightweight as the camera itself. Sporting a 5-axis image stabilization system, decent electronic viewfinder, an impressive 8.6fps burst shooting speed and 4K video, it’s no toy – the E-M10 Mark III is a properly powerful camera.
While most digital cameras with interchangeable lenses feature a lens-mount of some kind, there are also a number of modular cameras, where the shutter and sensor are incorporated into the lens module.
In the single-lens reflex camera, the photographer sees the scene through the camera lens. This avoids the problem of parallax which occurs when the viewfinder or viewing lens is separated from the taking lens. Single-lens reflex cameras have been made in several formats including sheet film 5×7″ and 4×5″, roll film 220/120 taking 8,10, 12 or 16 photographs on a 120 roll and twice that number of a 220 film. These correspond to 6×9, 6×7, 6×6 and 6×4.5 respectively (all dimensions in cm). Notable manufacturers of large format and roll film SLR cameras include Bronica, Graflex, Hasselblad, Mamiya, and Pentax. However the most common format of SLR cameras has been 35 mm and subsequently the migration to digital SLR cameras, using almost identical sized bodies and sometimes using the same lens systems.
If your iPhone Camera is still missing at this point, you may have a hardware issue that is not related to updating iOS. If you suspect a hardware problem is causing your camera to go missing, you should visit an Apple Store or call an official Apple Support line to have a hardware problem remedied.
Here’s something nobody has talked about; the V750 & W850 basically run off of USB power! The battery charges inside the camera like phone (a stand alone battery charger is also available). The bundled charger is a 5V 1.8A USB charger. The charging port on the camcorder is one of those barrel style connectors and the so the charging cable is basically a USB to barrel plug cable.
It’s hard for me to say for sure, but I think either our main pick, or the cheaper Canon, should do the job. What’s the current camera you’re using? That might give me some indication of where the problems are.
Many incorporate a retractable lens assembly that provides optical zoom. In most models, an auto actuating lens cover protects the lens from elements. Most ruggedized or water-resistant models do not retract, and most with superzoom capability do not retract fully.
The GoPro Hero6 Black is the best action camera you can buy. It’s pricey compared to some of the competition, but it’s got a wealth of features, including shooting 4K footage at up to 60fps, as well as super-slow-motion 1080p video at 240fps. The improved image stabilization system works at treat, as well as footage offering a wider dynamic range and better low-light performance compared to the Hero5 Black. That’s not forgetting it’s waterproof down to 10m, has a useful 2-inch touchscreen, while the updated app with QuikStories automatically transfers and edits your footage for you. If you want an action camera, you’re not going to go wrong with the Hero6 Black.
“Hey,” you may say, “why do I need a video camera? I’ve got a cell phone that takes video!” That’s a fair point: for casual shooting a cell phone is fine. But cell phone video is all about limitations: A decent video camera does things that no cell phone or tablet can do.
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.
Ultimately, digital cameras and camcorders are built for the particular jobs they are meant to do. Camcorders are designed to be held aloft and steady for longer periods of time. While cameras are not. Camcorder LCD displays can be rotated to give you a multitude of angles. Most still cameras have fixed displays that can’t be moved. And the body design of both devices is made for the optimal experience while using each specific device.
An advanced compact for wide-angle and manual-photography fans, the Fujifilm X100F improves upon an already great camera with better autofocus performance and a fine-tuned design on top of its already excellent photo quality.
All of the video cameras produced excellent quality video in bright light, recording full HD at 1080p. They capture 60 frames of video a second, which translates into smoother motion and cleaner looking footage. The Panasonic was by far the best looking of the lot, with deeper, more saturated colors and better detail than the competition. This was the case across the board in most of our tests: the video from the Panasonic looked more realistic, had more accurate color, and smoother motion.
DSLRs have another big advantage over point-and-shoots—speed. The time that it takes between hitting the shutter button and the camera capturing a picture, referred to as shutter lag, and the wait time between taking photos—recycle time—are often concerns with compact cameras. DSLRs generally focus very quickly and deliver shutter lag that is nearly immeasurable.
So, for that price point it’s going to be tough to get everything you want. Before you dive straight into cameras, if your 8 yo already has access to a computer then you might want to consider a new webcam instead. Webcams have come a long way in quality and variety and tend to be pretty affordable. But before you do that, you might want to make a list of things that are important: will they want a touchscreen LCD or is navigating a menu system fine for them? Do they need a tilting screen or a fully articulating screen for “selfie” mode? Is slow motion video mode something they want? Do they really want to record in 1080p or is 720p sufficient? Will they ever want to use an external microphone or is in-camera mic good enough? That’s a lot for an 8 yo, I know, but you might be surprised by the features they know they want. That will help you narrow it down, as some cameras have flip screens but only shoot 720p, etc. You’re always sacrificing something so finding out what’s actually important will help you choose.
On June 11, 1997, Philippe Kahn instantly shared the first pictures from the maternity ward where his daughter Sophie was born. He wirelessly transmitted his cell phone pictures to more than 2,000 family, friends and associates around the world. Kahn’s wireless sharing software and camera integrated into his cell phone augured the birth of instant visual communications.[7][20] Kahn’s cell phone transmission is the first known publicly shared picture via a cell phone.[21]
