Most earlier digital camera backs used linear array sensors, moving vertically to digitize the image. Many of them only capture grayscale images. The relatively long exposure times, in the range of seconds or even minutes generally limit scan backs to studio applications, where all aspects of the photographic scene are under the photographer’s control.
The mid level Canon SLR is the new 24 megapixel Canon EOS 80D, aimed at photography enthusiasts. This replaces the 20 megapixel EOS 70D in the Canon EOS range. The 77D has also been recently added to the range, and is cheaper and lighter than the 80D, but lacks the weather sealing of the 80D and has some specs more in line with the 800D. There are two current advanced enthusiat DLSRs, the Canon 6D and Canon 7D mark II. The 20 megapixel 7D offers fast 10 frames per second shooting, and a host of advanced features. The Canon EOS 6D, unlike all the models above, is notable (and desirable) for being a full frame SLR, and is the cheapest full frame Canon SLR camera in the range.
All of the best DSLRs in this roundup support Raw capture for home processing, as well as JPEGs processed in-camera for your convenience. Furthermore, they offer the traditional PASM quartet of manual and semi-manual exposure modes, usually backed up by a range of fully automatic point-and-shoot modes (professional full-frame models exempted).
Lens mount: All of the DSLR manufacturers have their own proprietary lens-mount system. For Nikon this is the F-mount, for Canon it’s the EF-mount, and for Pentax its the K-mount. If you’re buying your first DSLR then it definitely pays to think ahead about lenses. This is because you’re effectively buying into a system, and once you’re in, you’re committed to that system. Specialist adapters that let you mount Canon lenses on Nikon bodies (and vice versa) are available, but they can be expensive and largely impractical.
The sensors used in current DSLRs (“Full-frame” which is the same size as 35 mm film (135 film, image format 24×36 mm), APS-C sized, which is approximately 22×15 mm, and Four Thirds System) are typically much larger than the sensors found in other types of digital cameras. Entry-level compact cameras typically use sensors known as 1/2.5″, which is 3% the size of a full frame sensor. There are bridge cameras (also known as premium compact cameras or enthusiast point-and-shoot cameras) that offer sensors larger than 1/2.5″ but most still fall short of the larger sizes widely found on DSLR. Examples include the Sigma DP1, which uses a Foveon X3 sensor; the Leica X1; the Canon PowerShot G1 X, which uses a 1.5″ (18.7×14 mm) sensor that is slightly larger than the Four Thirds standard and is 30% of a full-frame sensor; the Nikon Coolpix A, which uses an APS-C sensor of the same size as those found in the company’s DX-format DSLRs; and two models from Sony, the RX100 with a 1″-type (13.2×8.8 mm) sensor with about half the area of Four Thirds and the full-frame Sony RX1. These premium compacts are often comparable to entry-level DSLRs in price, with the smaller size and weight being a tradeoff for the smaller sensor.

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.
Sensitivity: In the pre-digital days, all film used to come with a sensitivity rating. This indicated how sensitive to light it was: the higher the number, the more sensitive it was. In digital photography, sensitivity is controlled by the sensor and expressed as an ISO number. Again, the higher this is, the more sensitive the sensor will be to light. The main thing to bear in mind is that while higher ISO settings enable you to shoot in dimmer conditions, or at a higher shutter speed, they also increase the degree of noise that appears in your images.
The New York Times claimed that the Gaza Strip “has been racked by shortages of medicine and water after years of a blockade by Israel and Egypt.” In fact, the West Bank-based Palestinian government is responsible for a scarcity in medicine, and overpumping from Gaza’s aquifer has degraded the territory’s water supply.
In 2012, Canon hybrid autofocus technology to the DSLR in the EOS 650D/Rebel T4i, and introduced a more sophisticated version, which it calls “Dual Pixel CMOS AF”, with the EOS 70D. The technology allows certain pixels to act as both contrast-detection and phase-detection pixels, thereby greatly improving autofocus speed in live view (although it remains slower than pure phase detection). While several mirrorless cameras, plus Sony’s fixed-mirror SLTs, have similar hybrid AF systems, Canon is the only manufacturer that offers such a technology in DSLRs.
Following Haaretz’s correction, The Jerusalem Post also corrects a headline which falsely alleged that Israel is handing out cash prizes to civilians who deport African asylum seekers. The real story is that the Population and Immigration Authority is hiring.

If you are just getting started, the Nikon D3400 is a great place to get to know DSLR cameras. It is intuitive with enough features to experiment with, while the guide mode can take you through the fundamentals of getting a perfect shot.
At its core, the 200D is built around the same 24.2-megapixel APS-C sensor used inside the 77D and 800D, which is paired with Canon’s latest DIGIC 7 image processor. This raises the camera’s maximum burst speed up to 5fps – one frame faster than its predecessor.
Unlike DSLRs, most digital cameras lack the option to change the lens. Instead, most compact digital cameras are manufactured with a zoom lens that covers the most commonly used fields of view. Having fixed lenses, they are limited to the focal lengths they are manufactured with, except for what is available from attachments. Manufacturers have attempted (with increasing success) to overcome this disadvantage by offering extreme ranges of focal length on models known as superzooms, some of which offer far longer focal lengths than readily available DSLR lenses.

The powerful Olympus Tough TG-5 is waterproof to depths of up to 50 feet, which isn’t the deepest among compact point-and-shoots, but will suffice for snorklers. With its 4x optical zoom lens (24mm-100mm), which has a wide, f/2.0 maximum aperture, the TG-5’s lens offers very good quality photos and beautiful video at 4K-resolution. It can also shoot RAW photos, which means it will do a better job than most in darker underwater scenes, and the Olympus features several special underwater modes, as well.
In case shooting the huge files generated by its 36.3MP sensor is getting problematic for your poor memory cards, the D810 does also provide the handy option to shoot in ‘S Raw’ – letting you shoot uncompressed at 9MP for files a bit more manageable.
DSLR cameras help amateur and professional photographers alike achieve sharp, dynamic photos. DSLR stands for digital single lens reflex, which refers to the technology these cameras use to ensure a consistent level of photographic quality. When choosing the right device, there are many factors to consider, ranging from megapixels to exposure options.
Multi-shot exposes the sensor to the image in a sequence of three or more openings of the lens aperture. There are several methods of application of the multi-shot technique. The most common originally was to use a single image sensor with three filters passed in front of the sensor in sequence to obtain the additive color information. Another multiple shot method is called Microscanning. This method uses a single sensor chip with a Bayer filter and physically moved the sensor on the focus plane of the lens to construct a higher resolution image than the native resolution of the chip. A third version combined the two methods without a Bayer filter on the chip.
Nikon at first produced an aperture-priority camera, but later made subtle changes on the inside of their bayonet mount, which allowed for shutter-priority automation without obsoleting the photographers lenses.

Almost all SLR cameras use a front surfaced mirror in the optical path to direct the light from the lens via a viewing screen and pentaprism to the eyepiece. At the time of exposure the mirror is flipped up out of the light path before the shutter opens. Some early cameras experimented with other methods of providing through-the-lens viewing, including the use of a semi-transparent pellicle as in the Canon Pellix and others with a small periscope such as in the Corfield Periflex series.
The Nikon D200, a semi pro DSLR camera that shares similar controls / specification with its ‘bigger brother’ the the D2X. The D200 has the robust build quality of the D2X, a 10.2 million pixel CCD sensor and a compact design more like the D100.
Olympus and Panasonic released many Micro Four Thirds cameras with interchangeable lenses which are fully compatible each other without any adapter, while the others have proprietary mounts. In 2014, Kodak released its first Micro Four Third system camera.
PASM: All DSLRs provide the standard exposure mode quartet of Program, Aperture-priority, Shutter-priority and Manual modes. These are usually denoted on the camera’s mode dial by the letters P, A, S and M. The only slight departure from this is that Canon cameras indicate Aperture-priority as Av (Aperture value) on the mode dial, while Shutter-priority is written as Tv (Time value).
The original Canon 5D, launched in 2005, was the first ‘affordable’ full-frame DSLR. Since then the 5D range has undergone several revisions, with the 5D Mark IV being the latest in the line. Released towards the end of 2016, the 5D Mark IV sticks to the tried-and-tested 5D template of being richly featured and highly customisable, while also introducing a raft of hardware and performance upgrades along with some all-new technology not previously seen in a Canon DSLR.

As a small matter of history, the first 35 mm camera (non-SLR) to feature through the lens light metering may have been Nikon, with a prototype rangefinder camera, the SPX. According to the website below, the camera used Nikon ‘S’ type rangefinder lenses.
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.
