User-friendly and packed with features
Ready to make the leap into the world of full-frame mirrorless photography? Sony's Alpha a7 IV is packed with features that creators of all experience levels can appreciate. I especially like this camera's intuitive color-coded menu system, which lets you easily change shooting modes and exposure settings.
Add in dual memory card slots, advanced in-body image stabilization, and spectacular autofocus and you've got a user-friendly mirrorless camera that's equally skilled at capturing beautiful stills and vibrant 4K video footage.
The Alpha a7 IV sports a full-size HDMI output for connecting to an optional external monitor.
Built for the elements
Sony equipped the Alpha a7 IV with a rugged magnesium-alloy body that's weather-sealed against dust and moisture. Use it with confidence to capture photos and videos at weddings, sporting events, and other fun outdoor activities.
Pair it with premium glass for the best image quality
I'm a Canon shooter by trade, but one reason I'd be tempted to switch to Sony is their outstanding lineup of E-mount lenses.
Sony makes some of the best optical elements on the planet, and their E-mount lenses (especially their higher-end glass) are world-famous for their light-gathering abilities and quick, ultra-sharp focusing.
This kit includes Sony's 28-70mm f/3.5-5.6 FE OSS zoom lens, which is great for landscape, street, event, portrait, and travel photography. The wide field-of-view also makes it ideal for video recording, including vlogging.

Smart Digital Zoom is available for still images for full frame (1.5x to 2x), and APS-C (1.3x). Standard Digital Zoom can be used for full frame and APS-C images (4x to 8x) and for movies (4x).
Focus Modes: The α7 IV's Fast Intelligent auto focus system combines the high-speed BIONZ XR image processor and improved algorithms with optimized image sensor read-out speed to provide ultra-fast auto focusing. You can choose from the following Auto/Manual Focus Modes:
- AF-S (Single-shot Auto focus): The camera focuses and the focus is locked when you press the shutter button halfway down. Recommended for use with motionless subjects.
- AF-A (Automatic Auto focus): The camera locks the focus when it determines that the subject is motionless, or continues to focus when the subject is in motion. During continuous shooting, the camera automatically shoots with Continuous AF from the second shot.
- AF-C (Continuous Auto focus): The camera continues to focus while the shutter button is pressed and held halfway. Recommended for use when the subject is in motion.
- Direct Manual Focus (DMF): After focusing automatically, you can make fine focusing adjustments manually by turning the focus ring on the lens.
- Manual Focus: When it is difficult to get the proper focus in auto focus mode, you can adjust the focus manually. This mode allows you to set the distance of a subject by rotating the focusing ring to achieve a sharp focus.
AF (Auto focus) Area: The α7 IV features 759 focus points for phase-detection auto focusing in full frame mode with full frame lens. In APS-C mode it has 713 points with full frame lens and 575 points with APS-C lens. The camera has 425 contrast-detection focus points. You can select between 6 settings:
- Wide: The camera focuses automatically on a subject in all ranges of the image.
- Zone: You can select a zone on the monitor on which to focus.
- Center Fix: The camera uses the AF area located in the center area exclusively.
- Spot: You can change the size of and move the focusing area in order to focus on a small subject or narrow area.
- Expand Spot: If focus isn't possible on the single selected point, it uses focus points around the flexible spot as a secondary focus area to facilitate focus.
- Tracking: When the shutter button is pressed halfway, the camera tracks the subject within the select AF area. You can select the desired tracking start area by designating the area as a flexible spot or an expanding flexible spot.
Eye AF: The Eye AF function has been improved with more effective eye detection and tracking, even when shooting a moving portrait subject, or if the subject is looking down or away, or is backlit. When photographing your pet or wildlife, the Animal-eye AF automatically detects and tracks the eyes of animals or birds.
Face Detection: The camera can detect human faces, and adjusts the focus, exposure, performs image processing and adjusts flash settings for best results. Faces can be registered, and priority given to those faces over others in the frame. Up to 8 faces can be detected and/or registered.
AF Illuminator: When you press the shutter button halfway down a red illuminator is emitted until the focus is locked. Under dark lighting conditions or when you shoot a low contrast subject, the AF illuminator allows the camera to focus more easily on the subject.
In-body Stabilization: The α7 IV is equipped with a sensor-shift-type in-body image stabilization system to reduce the effect of camera shake. This system is carefully fine-tuned to match the 33MP performance of the camera, allowing you to photograph faraway objects without the blur of camera shake. It features 5-axis compensation with an effect equivalent to 5.5 stops faster shutter speed. It can compensate for camera shake in the following ways: pitch, yaw, X-axis, Y-axis, and roll.
Drive Modes: The camera offers the following shooting modes: Single shooting, Continuous Shooting, Self-timer (Single), Self-timer (Continuous), and Bracketing (continuous, single, white balance, and DRO).
Continuous Shooting: The camera can record still images continuously while the shutter release button is held down. You can select from the following speeds: Hi+ (10 fps), Hi (8 fps), Mid (6 fps), and Low (3 fps). In most cases, you can record up to 1000 images, depending on the file format and the memory card capacity.
Self-Timer: You can set the camera to several self-timer settings:
- 10 Second: After you press the shutter button, the shutter will be released about 10 seconds later. This is convenient when the photographer wants to appear in a photo.
- 5 Second: After you press the shutter button, the shutter will be released about 5 seconds later. This is convenient when the photographer wants to appear in the photo.
- 2 Second: After you press the shutter button, the shutter will be released about 2 seconds later. This is convenient to reduce camera-shake.
- Continuous Self-timer: The camera records 3 or 5 images continuously after a 10, 5, or a 2 second delay. You can choose the best shot from the multiple shots taken.
- Bracketing Self-timer: The camera records multiple images, each with a different exposure, after a 10, 5, or 2 second delay.
Bracket Shooting: Bracket shooting allows you to shoot 3 images, each with different degrees of exposure, white balance, flash intensity, and dynamic range. You can select the increment steps for each frame of the bracket.
Interval Shooting: The Interval Shooting function lets you automatically shoot a series of still images and create a time-lapse movie from the images using Imaging Edge Desktop software. You can set the following:
- Shooting Start Time: the time from when you press the shutter button to when interval shooting starts (1 second to 99 minutes 59 seconds)
- Shooting Interval: the time from when one exposure starts to when the next exposure starts (1 second to 60 seconds).
- Number of Shots: the number of shots for interval shooting (1 shot to 9,999 shots)
- AE Tracking Sensitivity: tracking the auto exposure vs. the change in luminance during interval shooting (low, mid, high).
- Shutter Type: mechanical shutter or electronic shutter
- Shoot Interval Priority: whether or not to prioritize the shooting interval when the exposure mode and the shutter speed becomes longer than the shooting interval. (Off/On)
Exposure Modes: The top-mounted Mode Dial lets you select from the following exposure modes:
- iAuto (Intelligent Auto): This mode allows easy shooting with settings adjusted automatically using scene recognition.
- Program Auto (P): For shooting with the exposure adjusted automatically (both the shutter speed and the aperture value), while allowing you to adjust other settings manually.
- Aperture Priority (A): This mode allows you to shoot after adjusting the aperture value manually, letting the camera set the appropriate shutter speed. This mode gives you greater control over the depth of field.
- Shutter Speed Priority (S): This mode allows you to shoot after adjusting the shutter speed manually, letting the camera set the appropriate aperture. You can choose a shutter speed of 1/8000 to 30 seconds for still images, or 1/8000 to 1/4 second for movies. With a high shutter speed, the moving subject appears as if it is frozen on the image. With a slow shutter speed, the moving subject appears as if it were flowing. Bulb photography is also available in this mode.
- Manual Exposure (M): This mode allows you to shoot after adjusting the exposure (shutter speed and aperture) manually.
- Memory Recall (1, 2, 3): You can register often-used camera settings (including Shooting Mode, Aperture, Shutter speed) in one of three memory positions on the Mode Dial for easy recall.
Still/Movie/S&Q Dial: Using the ring around the Mode Dial, you can quickly and easily switch between still image shooting, movie recording, and S&Q (Slow-motion/Quick-motion) shooting mode.
Exposure Compensation: Exposure compensation is used to alter the camera's standard exposure setting. You can make the image look lighter (increased exposure) or darker (decreased exposure) The exposure compensation amount can be adjusted using the rear dial on the camera +/-5.0 EV in 1/3-step or 1/2-step increments. For movies, you can adjust the exposure compensation value within a range of +/-2.0EV for movies.
Metering Mode: A 1200-zone evaluative sensing system provides multi-pattern measuring for superior exposure control accuracy in a wide range of lighting conditions. You can select the method for measuring the brightness of a subject from the following methods:
- Multi-pattern: This method uses the whole screen divided into 1200 zones to measure light.
- Center-weighted: While emphasizing the central area of the screen, this method measure the average brightness of the entire screen.
- Spot: This method measure light only in the spot metering circle in the center of the frame.
- Entire Screen Average: Measures the average brightness of the entire screen.
- Highlight: Measures the brightness while emphasizing the highlighted area on the screen.
White Balance: You can adjust the color tones according to the lighting conditions. You can choose from the following WB options, and adjust the +/- 3 to fine tune the colors: Auto WB, Auto (Ambience), Auto (White), Daylight, Shade, Cloudy, Incandescent, Fluorescent (Warm White), Fluorescent (Cool White), Fluorescent (Day White), Fluorescent (Daylight), Flash, Underwater, and Custom (1, 2, 3).
Color Temperature/Color Filter: You can adjust the white balance further by selecting Color Temperature or Color Filter in the Custom White Balance option. With Color Temperature, the higher the number, the more reddish the image, and the lower the number, the more bluish the image. Color Filter achieves the effect of Color Compensation filters for photography. Based on the set color temperature as the standard, the color can be compensated to Green (G) or Magenta (M).
ISO Settings: ISO is a unit of measurement of sensitivity to light. The larger the number, the higher the sensitivity. The camera's ISO can be set manually or automatically, depending upon the exposure mode. For still images, the sensitivity can be set to ISO 100 to 51200, expandable to ISO 50 (min) and ISO 204,800 (max).
