- Product Set: w/ 28-70mm Lens
- Camera Model Family: Sony a7 IV
- Digital Camera Type: Mirrorless Camera with Lens
- Imaging
- Image Sensor Type: CMOS (CCD and CMOS are the two main technologies used in image sensors. CCD, the older of the two types, turns analog light signals into digital pixels. This conversion happens without distortion, resulting in high-quality images. Newer CMOS sensors use transistors at each pixel to move electrical charges. CMOS sensors are typically less expensive, but also require more light to create distortion-free images.)
- Image Sensor Size: 35mm Full Frame (36 x 24 mm)
- Total Pixels: 34 megapixels (Generally, the more pixels, the higher the image resolution and the finer the detail that can be seen.)
- Image Resolution (Display): 3840 x 2160 (Refers to the number of pixels, both horizontally and vertically, used to either capture an image or display it. The higher the resolution the finer the image details.)
- Zoom Capability: true (This function allows for magnification of the subject.)
- Digital Zoom: 8x (A digital zoom is accomplished electronically, with no adjustment of the camera's optics, and no optical resolution gained in the process. The existing data is not enhanced or added to, merely displayed at a lower resolution, thereby giving an illusion of an enlarged image.)
- In-Camera Image Stabilization: true (This feature helps reduce image blurring from camera motion. In-camera stabilization means the image sensor itself moves to counteract detected motion.)
- Low Light/High Sensitivity: true (High sensitivity digital imaging devices are designed to work in low light conditions to produce a high dynamic range image.)
- Image File Format(s): JPEG, RAW (Standardized software format(s) of storing digital images. The type of format chosen for capturing and compressing the image can determine quality, level of detail, and storage space required.)
- Focus
- Autofocus: true (Allows the camera to automatically focus through the lens, rather than by adjusting the lens manually.)
- Eye Autofocus (Eye AF): true (Automatically seeks out and focuses on the subject's eye and holds it as the camera and subject move and as the photographer shoots at high frame rates.)
- Exposure Control
- Shutter Speeds: 1/8000 (The length of time the shutter remains open when the shutter release is activated, expressed in fractions of seconds. The longer the shutter is open, the more light that is able to be captured by the camera sensor.)
- Minimum Aperture: f/22 (The smallest opening of a lens, typically expressed in f-numbers. The larger the number, the smaller the aperture and the less light that can enter the lens. A smaller aperture creates a larger depth of field, which keeps both foreground and background in focus.)
- Maximum Aperture: f/5.6 (The limit to how wide a lens can be open, typically expressed in f-numbers. The smaller the number, the larger the aperture and the more light that can enter the lens. A larger aperture creates a shallower depth of field, helpful for keeping subjects in focus and blurring background details.)

Photographers swiss army knife
Truly gets the job done, beautiful quality, better than the a7iii just because u wont have to upgrade gor a while, and way better than my old cannon rebel t7. Auto focus is awesome, and the custome setting’s definitely make it easy to switch to for any situation, shot music videos, advertisements, sports highlights, and being able to switch to photography on the fly is another amazing feature. I love it!

I bought the A7 IV to take my barber content to the next level, and this thing delivered immediately. No exaggeration — a client loved his cut so much that the very next day he wrote me a check and told me, “Make it happen.” That’s literally how I ended up buying this camera. The autofocus is insane. It locks onto a fade like it understands what a clean blend is supposed to look like. Every lineup, every design, every detail shows up crazy crisp. Low-light performance is perfect for shop settings — whether it’s ring lights, window light, or late-night cuts, my shots stay clean with zero grain. For video, the stabilization makes handheld shots look like a full production team filmed them. Colors come out natural and accurate, so my work barely needs any editing. My reels instantly started looking more premium. If you’re a barber or creator trying to stand out, this camera is one of the best investments you can make. It paid itself off in energy, quality, and opportunities from day one. Follow my work to see what this camera can really do: @cutzbychris

Sony a7 4
recently purchased the Sony A7 IV from Best Buy, and I couldn’t be happier with my decision. As someone who shoots both photo and video content, this camera strikes the perfect balance between professional-level performance and ease of use. Image Quality: The 33MP full-frame sensor delivers incredibly sharp, detailed images with great dynamic range. Colors are vibrant yet natural, and low-light performance is top-notch — minimal noise even at higher ISOs. Video Features: One of the main reasons I upgraded was for video, and the A7 IV truly shines here. 4K 60p with 10-bit 4:2:2 internal recording gives me cinematic quality straight out of the camera. S-Cinetone is a game-changer for beautiful skin tones, and the autofocus in video is insanely accurate. Autofocus & Performance: Sony’s real-time Eye AF for humans and animals is blazing fast and incredibly accurate. Whether I'm shooting portraits or fast-moving action, the A7 IV keeps up effortlessly. Build & Usability: The updated grip feels solid and comfortable in hand. Dual card slots, full-size HDMI, and the fully articulating touchscreen make this camera incredibly versatile for creators on the go. Bonus: Huge shoutout to Best Buy for the fast shipping and great packaging. Their customer service is always reliable, and I felt confident purchasing such a high-end product through them. Overall: If you’re looking for a camera that can handle professional photography and serious video work, the Sony A7 IV is an unbeatable choice. It’s an investment — but one that pays off in every shot. Highly recommended!
