Manufacturer description

SAN DIEGO, CA – September 14, 2020 – Today, Sony Electronics Inc. announced several additions to an already impressive imaging lineup — the Alpha 7C full-frame camera (model ILCE-7C), the FE 28-60mm F4-5.6 (model SEL2860) zoom lens and HVL-F28RM flash.

The Alpha 7C is the world’s smallest and lightest[ii] full-frame body with uncompromising performance, featuring advanced AF (autofocus), high-resolution 4K video[iii] capabilities and more. When paired with the world’s smallest and lightest[iv] FE 28-60mm F4-5.6 standard zoom lens, this versatile combination delivers an experience unlike any other, maximizing portability and versatility without sacrificing any of the power of full-frame imaging. The HVL-F28RM flash allows users to broaden their photo expressions with outstanding compactness, and an intelligent light intensity control linked to camera face detection[v].

“We are committed to creating the best tools possible, based on the needs of our customers,” said Neal Manowitz, deputy president of Imaging Products and Solutions Americas, Sony Electronics. “The new Alpha 7C camera and FE 28-60mm F4-5.6 zoom lens pack many of our most advanced imaging technologies in a brand new design that is the smallest and lightest full-frame camera and lens system in the world. This opens up a new world of possibilities for creators, giving them the uncompromised power of a full-frame system in the palm of their hand.”

New Alpha 7C: Uncompromised Full-frame Performance in a Compact Design

The new Alpha 7C combines Sony’s full-frame image quality, advanced AF capabilities and versatile video shooting functions in a stunningly light and compact design. The new camera features a 24.2MP (approx. effective) 35mm full-frame back-illuminated Exmor R™ CMOS sensor and BIONZ X™ image processing engine, offering high sensitivity, outstanding resolution, 15-stop[vi] wide dynamic range and high-speed image data processing.

Measuring only 4.9 inches x 2.8 inches x 2.2 inches (124.0mm x 71.1mm x 59.7mm) and weighing just 18oz (509g)[vii], the Alpha 7C is similar in size and weight to an APS-C camera[viii], with only 1 percent more weight than the Alpha 6600. The Alpha 7C achieves the world’s smallest and lightest compact body[ii] through upgraded 5-axis in-body stabilization and shutter units, and the utilization of magnesium alloy monocoque construction, often used in the bodies of cars and aircraft. Even in this compact body, the Alpha 7C features a 5-step[ix] stabilization effect that allows for shooting snaps without a tripod. Moreover, despite the compact body, the high-capacity NP-FZ100 battery provides enough power for long shooting durations and to capture up to an industry-leading[x] 740 images[xi] when using the LCD monitor, or 680 images[xi] when using the viewfinder.

Outstanding Full-frame Image Quality

Sony’s new Alpha 7C combines high resolution with low noise for excellent image quality at all sensitivities, offering the user stunning image quality for shooting everyday photography and movies such as nature, portraits, sports, street photography and more. Standard ISO extends up to 51,200 and is expandable from ISO 50-204,800[xii] for low-light environment captures with low noise. The Alpha 7C also supports 16-bit processing and 14-bit RAW output[xiii] for natural gradations.

Advanced Autofocus

Using AI-driven functions, the Alpha 7C’s Real-time Tracking[xiv] maintains accurate focus automatically while the shutter button is half-pressed. In addition, “Tracking On + AF-On” is now assignable to a custom key and can be activated at once while the AF-ON button is pressed. Moreover, the intended subject can be specified just by touching it on the monitor when “Touch Tracking” has been turned ON via the menu and is available for both stills and movies. The Alpha 7C’s AF functions also feature Real-time Eye AF for both humans and animals to achieve fast and accurate focus[xvi]. When using Real-time Tracking while “Face/Eye Priority in AF” is ON with a human subject, the subject’s eye and face is detected and locked on in real-time with extremely high tracking precision.

The Alpha 7C provides wide, fast, reliable AF that locks onto the intended subject instantly without losing focus, thanks to its 693-point focal-plane phase-detection AF system covering approximately 93 percent of the image area, with an additional 425 contrast-detection points to ensure reliable focus, even in busy environments.

The Alpha 7C also features continuous shooting at up to 10 fps[xvii] with AF/AE (autoexposure) by using a newly developed shutter unit and refined image processing system. It is also possible to shoot continuously at up to 8 fps[xvii] in live view mode, with minimal viewfinder/monitor display lag for easy, stable framing, even with intense subject motion. The Alpha 7C allows up to approximately 223 JPEG (Fine L) images, 115 compressed RAW images, or 45 uncompressed RAW images to be captured in one continuous burst[xviii], and achieves highly accurate and reliable AF precision in light down to EV-4[xix]. These features make it easier to capture fast moving subjects in challenging environments.

Expanded Video Capabilities

Full-frame full-pixel readout without the need for pixel binning makes it possible to capture more than twice[xx] the amount of data required for 4K video (QFHD: 3840 x 2160)[iii], which is then oversampled to produce high quality 4K footage with exceptional detail and depth. In addition, the Alpha 7C supports HDR (HLG[xxi]) and S-Log/S-Gamut profiles, Slow & Quick motion, high-speed full HD recording at 120 fps[iii] and other advanced video features for additional creative freedom.

Furthermore, the Alpha 7C features Real-time Eye AF (human) for video shooting. The eye is automatically tracked with high precision and reliability so that the operator can concentrate on the content rather than focus operation. Users can also customize AF Transition Speed in seven settings, and AF Subject Shift Sensitivity in five settings, in their preferences. Touch Tracking functionality is also available for movie shooting.

The Alpha 7C features a side-opening vari-angle LCD monitor, making it easy to record selfies, overhead shots, low ground-level shots or whatever the user requires. The MOVIE button has been positioned on the top of the camera making it easier to operate while recording in selfie mode. The new Alpha 7C not only records high-quality video, but also high-quality audio. A digital audio interface has been added to the camera’s Multi Interface (MI) Shoe, allowing the ECM-B1M Shotgun Microphone or XLR-K3M XLR Adaptor Kit can be connected to input digital audio signals directly to the MI shoe for cleaner, clearer audio recordings. Like other MI shoe accessories, no cables or batteries are required, providing unrestrained freedom for Alpha system moviemaking. Headphone and microphone jacks are also provided to accurately monitor recorded sound, and metadata attached to movie footage shot vertically on the camera allows the footage after transfer to the smartphone or similar device, to also be replayed and edited in the vertical position.

Designed for Reliable Operation

The Alpha 7C is designed with the user in mind. The touch panel LCD monitor is a large touch-sensitive 3.0 type with approximately 921 thousand dots, providing optimal visibility even in bright outdoor conditions, and supporting touch focus, tracking and shutter operations. The Alpha 7C also features a high-quality view mode for finer, more natural detail in addition to a 2.35 megadot (approx.) XGA OLED Tru-Finder™ EVF. The Alpha 7C offers functions that simplify operation during and after shooting, such as Fn button customizations and more. It is also dust and moisture resistant[xxii] to support shooting needs in challenging environments.

To simplify workflow needs, Wi-Fi compatible wireless-communication functions allows images and movies to be directly transferred[xxiii] to a smartphone or tablet for convenient sharing, viewing or saving. In addition to the conventional 2.4GHz band, support for the 11ac standard allows transfer via 5GHz band (IEEE 802.11a/b/g/n/ac)[xxiv] so that users can select that stable and high-speed transfer with low interference. A USB Type-C® connector that supports SuperSpeed USB 5Gbps (USB 3.2) is also provided, allowing fast transfer of images during PC remote shooting and power supply from external mobile batteries.

Cannot perform comparison

Cannot compare the lens to itself.

Image stabilizer

A technology used for reducing or even eliminating the effects of camera shake. Gyro sensors inside the lens detect camera shake and pass the data to a microcomputer. Then an image stabilization group of elements controlled by the microcomputer moves inside the lens and compensates camera shake in order to keep the image static on the imaging sensor or film.

The technology allows to increase the shutter speed by several stops and shoot handheld in such lighting conditions and at such focal lengths where without image stabilizer you have to use tripod, decrease the shutter speed and/or increase the ISO setting which can lead to blurry and noisy images.

Original name

Lens name as indicated on the lens barrel (usually on the front ring). With lenses from film era, may vary slightly from batch to batch.

Format

Format refers to the shape and size of film or image sensor.

35mm is the common name of the 36x24mm film format or image sensor format. It has an aspect ratio of 3:2, and a diagonal measurement of approximately 43mm. The name originates with the total width of the 135 film which was the primary medium of the format prior to the invention of the full frame digital SLR. Historically the 35mm format was sometimes called small format to distinguish it from the medium and large formats.

APS-C is an image sensor format approximately equivalent in size to the film negatives of 25.1x16.7mm with an aspect ratio of 3:2.

Medium format is a film format or image sensor format larger than 36x24mm (35mm) but smaller than 4x5in (large format).

Angle of view

Angle of view describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view.

As the focal length changes, the angle of view also changes. The shorter the focal length (eg 18mm), the wider the angle of view. Conversely, the longer the focal length (eg 55mm), the smaller the angle of view.

A camera's angle of view depends not only on the lens, but also on the sensor. Imaging sensors are sometimes smaller than 35mm film frame, and this causes the lens to have a narrower angle of view than with 35mm film, by a certain factor for each sensor (called the crop factor).

This website does not use the angles of view provided by lens manufacturers, but calculates them automatically by the following formula: 114.6 * arctan (21.622 / CF * FL),

where:

CF – crop-factor of a sensor,
FL – focal length of a lens.

Mount

A lens mount is an interface — mechanical and often also electrical — between a camera body and a lens.

A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock type. Modern camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body, unlike screw-threaded mounts.

Lens mounts of competing manufacturers (Canon, Nikon, Pentax, Sony etc.) are always incompatible. In addition to the mechanical and electrical interface variations, the flange focal distance can also be different.

The flange focal distance (FFD) is the distance from the mechanical rear end surface of the lens mount to the focal plane.

Lens construction

Lens construction – a specific arrangement of elements and groups that make up the optical design, including type and size of elements, type of used materials etc.

Element - an individual piece of glass which makes up one component of a photographic lens. Photographic lenses are nearly always built up of multiple such elements.

Group – a cemented together pieces of glass which form a single unit or an individual piece of glass. The advantage is that there is no glass-air surfaces between cemented together pieces of glass, which reduces reflections.

Focal length

The focal length is the factor that determines the size of the image reproduced on the focal plane, picture angle which covers the area of the subject to be photographed, depth of field, etc.

Speed

The largest opening or stop at which a lens can be used is referred to as the speed of the lens. The larger the maximum aperture is, the faster the lens is considered to be. Lenses that offer a large maximum aperture are commonly referred to as fast lenses, and lenses with smaller maximum aperture are regarded as slow.

In low-light situations, having a wider maximum aperture means that you can shoot at a faster shutter speed or work at a lower ISO, or both.

Closest focusing distance

The minimum distance from the focal plane (film or sensor) to the subject where the lens is still able to focus.

Closest working distance

The distance from the front edge of the lens to the subject at the maximum magnification.

Magnification ratio

Determines how large the subject will appear in the final image. For example, a magnification ratio of 1:1 means that the image of the subject formed on the film or sensor will be the same size as the subject in real life. For this reason, a 1:1 ratio is often called "life-size".

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Electronic manual focus override is performed in the following way: half-press the shutter button, wait until the camera has finished the autofocusing and then focus manually without releasing the shutter button using the focusing ring.

Electromagnetic diaphragm control system

Provides highly accurate diaphragm control and stable auto exposure performance during continuous shooting.

Manual diaphragm

The diaphragm must be stopped down manually by rotating the detent aperture ring.

Preset diaphragm

The lens has two rings, one is for pre-setting, while the other is for normal diaphragm adjustment. The first ring must be set at the desired aperture, the second ring then should be fully opened for focusing, and turned back for stop down to the pre-set value.

Semi-automatic diaphragm

The lens features spring mechanism in the diaphragm, triggered by the shutter release, which stops down the diaphragm to the pre-set value. The spring needs to be reset manually after each exposure to re-open diaphragm to its maximum value.

Automatic diaphragm

The camera automatically closes the diaphragm down during the shutter operation. On completion of the exposure, the diaphragm re-opens to its maximum value.

Fixed diaphragm

The aperture setting is fixed at F/ on this lens, and cannot be adjusted.

Number of blades

As a general rule, the more blades that are used to create the aperture opening in the lens, the rounder the out-of-focus highlights will be.

Some lenses are designed with curved diaphragm blades, so the roundness of the aperture comes not from the number of blades, but from their shape. However, the fewer blades the diaphragm has, the more difficult it is to form a circle, regardless of rounded edges.

At maximum aperture, the opening will be circular regardless of the number of blades.

Weight

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

Maximum diameter x Length

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

For lenses with collapsible design, the length is indicated for the working (retracted) state.

Weather sealing

A rubber material which is inserted in between each externally exposed part (manual focus and zoom rings, buttons, switch panels etc.) to ensure it is properly sealed against dust and moisture.

Lenses that accept front mounted filters typically do not have gaskets behind the filter mount. It is recommended to use a filter for complete weather resistance when desired.

Fluorine coating

Helps keep lenses clean by reducing the possibility of dust and dirt adhering to the lens and by facilitating cleaning should the need arise. Applied to the outer surface of the front and/or rear lens elements over multi-coatings.

Filters

Lens filters are accessories that can protect lenses from dirt and damage, enhance colors, minimize glare and reflections, and add creative effects to images.

Lens hood

A lens hood or lens shade is a device used on the end of a lens to block the sun or other light source in order to prevent glare and lens flare. Flare occurs when stray light strikes the front element of a lens and then bounces around within the lens. This stray light often comes from very bright light sources, such as the sun, bright studio lights, or a bright white background.

The geometry of the lens hood can vary from a plain cylindrical or conical section to a more complex shape, sometimes called a petal, tulip, or flower hood. This allows the lens hood to block stray light with the higher portions of the lens hood, while allowing more light into the corners of the image through the lowered portions of the hood.

Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle lenses. For wide angle lenses, the length of the hood cannot be as long as those for telephoto lenses, as a longer hood would enter the wider field of view of the lens.

Lens hoods are often designed to fit onto the matching lens facing either forward, for normal use, or backwards, so that the hood may be stored with the lens without occupying much additional space. In addition, lens hoods can offer some degree of physical protection for the lens due to the hood extending farther than the lens itself.

Teleconverters

Teleconverters increase the effective focal length of lenses. They also usually maintain the closest focusing distance of lenses, thus increasing the magnification significantly. A lens combined with a teleconverter is normally smaller, lighter and cheaper than a "direct" telephoto lens of the same focal length and speed.

Teleconverters are a convenient way of enhancing telephoto capability, but it comes at a cost − reduced maximum aperture. Also, since teleconverters magnify every detail in the image, they logically also magnify residual aberrations of the lens.

Lens caps

Scratched lens surfaces can spoil the definition and contrast of even the finest lenses. Lens covers are the best and most inexpensive protection available against dust, moisture and abrasion. Safeguard lens elements - both front and rear - whenever the lens is not in use.
