Other Enhancements of the Sony A7 IV Camera

• New heat dissipating structure | As found in the Alpha 7S III and flagship Alpha 1, the Sigma shaped heat sink effectively draws heat away from the sensor to allow 4K 60p 10 Bit 4:2:2 recording continuously for over an hour.
• Shutter closed on Power-Off | This function closes the shutter when the camera’s power is turned off, protecting the image sensor from dust and particles while changing lenses.
• Improved Imaging Edge Mobile touch control | Touch Tracking and Touch Focus can be controlled from the Imaging Edge Mobile application*1, adding extra AF control versatility. The focus frame is now shown on the application display, further enhancing operability.
• Image Stabilization metadata | The A7IV records gyro and lens metadata that can be used in the Catalyst Browse/Prepare applications to apply post-shoot image stabilization.
• Display with external HDMI device | It is now possible to simultaneously display 4K video on three devices: the camera monitor, an external HDMI recorder/monitor, and the Imaging Edge Mobile app connected via Wi-Fi.
• Imaging Edge Mobile Connection via Bluetooth | If Imaging edge Mobile and the camera are paired in advance, the camera keeps connecting with IEM, and only needs to be selected from the IEM menu to allow Wi-Fi transfer of images stored in the camera.
• Improved transfer speed | The Imaging Edge Mobile application now supports 5 GHz Wi-Fi for higher transfer speeds on top of 2.4GHz.
• FTP background transfer with 5GHz wireless | Allows transferring still image and movie files to a specified remote FTP server via 5GHz wireless LAN, high-speed wired LAN via a USB to Ethernet adapter, or a USB-tethered smartphone connection.
• A SuperSpeed USB 10Gbps (USB 3.2 Gen2) Type-C connector allows fast, stress-free wired PC Remote (tethered) shooting.

Advanced External Flash Control

• P-TTL flash metering for every frame in Lo, Mid, and Hi continuous shooting mode ensures stable illumination and consistent exposure for each frame, even when tracking fast-moving subjects in scenes where the light changes dramatically or the angle of view is changed
• Reduced flash trigger time lag
• External flash control allows the control of compatible flash and radio wireless commander units connected to the camera directly from the camera interface
• Control linked to the camera’s face detection for AWB and flash level control gives a natural colour tone on human faces considering the balance between the light incident on the subject’s face from the flash and from the environment. When more than one person is in the shot, flash will be optimized for the individual’s face on which the face or eye detection frame is displayed.

10.7x zoom lens for full-frame mirrorless cameras that covers the focal length range from 28mm wide-angle to 300mm telephoto

The greatest feature of the 28-300mm F4-7.1 VC is its 10.7x zoom focal length range. In response to users stating that 200mm is not quite long enough at the telephoto end for an all-in-one zoom lens, TAMRON has extended the focal length to 300mm. Exceptionally portable, the lens features a highly compact design. This single lens enables shooting in all situations in everyday life and during travel, including landscapes, snapshots, portraits and sports photography. It's an extremely versatile lens that lets users take photos in any situation of any subject without changing lenses.

Outstanding imaging performance

This new TAMRON zoom has an optical construction of 20 elements in 13 groups. It includes one XLD (eXtra Low Dispersion) lens element and an LD (Low Dispersion) lens element to efficiently control aberrations such as chromatic aberration. The BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating suppresses ghosting and flare, producing clear images even in backlit conditions. It boasts best-in-class image quality as an all-in-one zoom lens for full-frame mirrorless interchangeable lens cameras.

Lightweight and compact lens body

Despite covering a 10.7x focal length range from 28mm wide-angle to 300mm telephoto, the lens is very compact, with a length of only 126mm (5in) and a weight of 610g (21.5oz). Small and versatile, it can be casually carried anywhere, and users are unlikely to tire even after long hours of shooting. It's ideal for people who want to carry a smaller camera bag. Additionally, the lens makes it easy to frame accurately when shooting still and moving images while zooming in and out, such as sports and wildlife, and is designed to be comfortable to use.

Equipped with VXD, TAMRON’s top-class linear motor focus mechanism

The 28-300mm F4-7.1 VC is equipped with the VXD autofocus drive that includes TAMRON’s premium linear motor focus mechanism to ensure that the focus is attained quickly and accurately throughout the 10.7x zoom range. Upending the stereotype of all-in-one zoom lenses having slow autofocus, its nimble operation allows users to capture more fleeting photo opportunities. The quietness supports photography and videography in conditions that require silence.

TAMRON’s proprietary VC mechanism

Although it's compact, the 28-300mm F4-7.1 is equipped with TAMRON’s proprietary VC mechanism that lets users take steady photos, especially at the 300mm telephoto end of its broad 10.7x range. VC effectively suppresses camera shake that often occurs when shooting in the telephoto range or under low-light conditions, thereby helping users take sharp photos without a tripod.

High convenience and operability

• 67mm filter size, same as most other TAMRON lenses for mirrorless cameras 　　
• Focus Set Button for assigning camera function and TAMRON Lens Utility function 　　
• Enhanced overall lens design for user-friendly operation 　
• Zoom Lock mechanism
