sony a7r iiia mirrorless camera

blending speed and resolution
proving that speed, resolution, and video capabilities can all coexist, the sony a7r iiia is a versatile, high-performance camera characterized by not only its resolution, but by its multimedia versatility.

42.4 mp exmor r bsi cmos sensor and bionz x image processor
featuring a back-illuminated design, the full-frame 42.4-megapixel exmor r cmos sensor works with the bionz x image processor to offer high-resolution stills and video while minimizing noise and improving speed. This sensor structure works with gapless on-chip lens design and an anti-reflection coating, as well as eliminating the optical low-pass filter, to improve light collection and enhance detail. Also, the copper wiring layer dramatically improves data transmission speed for creating 14-bit, high-resolution 42.4-megapixel stills with a native sensitivity range from iso 100-32000, which can be further expanded to iso 50-102400. Also, it enables internal uhd 4k video recording with a wide dynamic range using the full width of the full-frame sensor. The bionz x processor also works in conjunction with a high-speed front-end lsi to realize faster processing times along with the ability to capture an impressive 15-stop dynamic range at low sensitivity values.

autofocus and image stabilization
an evolved 4d focus system now employs a combination of 399 phase-detection points, which cover approximately 68% of the frame, along with 425 contrast-detection areas for reliable and quick autofocus and subject tracking performance. This fast hybrid af system now achieves twice the focusing speed and more reliable tracking compared to previous a7r models, as well as improved low-light focusing response down to -3 ev.

lock-on af maintains focus on moving subjects throughout the use of a configurable frame that is set over the desired moving subject
expand flexible spot employs neighboring focus points to retain focus on moving subjects even if the originally selected point loses focus
eye af can be used to base focus on recognized human subjects eyes for portraits and is available in both af-s and af-c modes, for both stills and video. Eye af can be used when photographing animal subjects, too, with any focusing mode when shooting stills
focus magnifier function can be used for critical focus when homing in on minute subject details
rear touchscreen can also be used for touch focus control, and a touchpad focus control mode lets you use the rear screen intuitively while keeping your eye to the viewfinder
for more personalized control over focus, and benefitting working in either vertical or horizontal shooting orientation, the af area can be switched in orientation to better suit your subject matter
af tracking sensitivity can also be customized in five steps to match how a subject is moving
frequently used focus point settings can be memorized and recalled with a custom button for faster switching between focus settings

sigma 45mm f/2.8 dg dn contemporary lens for sony e

designed for full-frame sony e-mount mirrorless cameras, the fast and versatile sigma 45mm f/2.8 dg dn contemporary lens is a normal-length prime that optimizes size as well as weight while rendering notably smooth bokeh with rounded out-of-focus highlights in both the foreground and background. Coupled with its ability to soften the periphery of blurred images while enhancing the three-dimensional impression of an object, its 9.5"" minimum focusing distance makes it suitable for snapshots to tabletop photos, or any imagery where you wish to make your subject stand out.

though full-time manual focus is available, this lens is equipped with a stepping motor that enables smooth, high-speed autofocusing that is notably quiet whether utilizing features such as face/eye detection af or during video shooting. A rounded seven-blade diaphragm contributes to the smooth bokeh, and a lens hood is included, which can protect the front element as well as prevent stray light from causing flare.
