Sony Alpha 7 IV Full-frame Mirrorless Interchangeable Lens Camera (Body Only)

The full-frame 33MP Exmor R back-illuminated CMOS sensor delivers outstanding speed and superb image quality. The use of copper wiring contributes to higher transmission speeds and faster AD (analogue to digital) conversion, while fast sensor readout enables 10-bit 4:2:2 4K recording up to 60p. The sensor also provides improved color reproducibility, low-noise performance at all sensitivities, 15+stop dynamic range and increased AF (autofocus) speed and precision performance. Experience improved levels of color gradation and detail rendering as well as soft, natural-looking human skin textures.

BIONZ XR Image Processor For Up to 8x Processing Speed

The BIONZ XR engine, also used in the Sony Alpha 1 and Alpha 7S III models, provides up to an 8x increase in processing speed. The engine concentrates real-time processing of AF (autofocus), image recognition, and image quality adjustment to minimize processing latency for greatly increased movie and still processing power. The user interface, network, and file management processing are distributed to deliver fast response regardless of real-time processing load.

Beautiful Images With Reduced Noise

Building on the capabilities of the back-illuminated Exmor R image sensor, the powerful BIONZ XR processing engine reveals even higher subjective resolution combined with exquisite detail and texture even in medium and high sensitivity ranges. Impressively low levels of noise are achieved throughout the standard range of ISO 100-51200 (expandable to ISO 50-204800 for stills and ISO 100-102400 for movies).

Wide, 15-Stop Dynamic Range

Taking advantage of the camera's full dynamic range of 15 stops, the Alpha7 IV uses image data from the sensor's 33-megapixels1 to render remarkably delicate detail in landscapes and scenery. This stunning image quality is based on Sony's unrivalled experience at the front lines of both still-image and movie creation.

4K 60p Recording, 4:2:2 10-bit Recording

The Alpha 7 IV gives you an impressive range of video recording options. Full pixel readout without binning allows 4K 60p11 recording in Super 35 mode providing high-resolution smooth footage that can be edited to 2x and 2.5x slow-motion when rendered to 30p or 24p in post-production, and 4K 24p or 30p full pixel readout without binning in full-frame with 7K oversampling. For highly detailed and rich 4K content.

7K Oversampling for Beautifully Expressive, Richly Detailed Images 

Thanks to the increased 33MP1 resolution, the Alpha 7 IV oversamples 7K when recording full-frame 4K movies at up to 30p, resulting in high-resolution, highly detailed 4K for beautifully expressive, rich images. Select the mode that best suits your purpose, and let the camera deliver.

Beautiful Color Expression Made Simple, with S-Cinetone

The Alpha 7 IV supports S-Cinetone, based on expertise gained through development of the VENICE CineAlta professional cinema camera line. This look is responsible for the beautiful skin tones for which Cinema Line cameras like the FX9, FX6 and FX3 are widely acclaimed. It delivers natural mid-tones for healthy-looking skin color, plus soft colors and gorgeous highlights. It's easy to create a more expressive look for your movie imagery without post-editing, since S-Cinetone is processed in-camera.

Sony Alpha 7 IV Full-frame Mirrorless Interchangeable Lens Camera (Body Only)

Sony Alpha 7 IV Full-frame Mirrorless Interchangeable Lens Camera (Body Only) SKU: ILCE7M4B

Rated 5 out of 5 by from Sony quality doesn’t disappoint. Impressive Sony quality. I upgraded from the Alpha 3. I wanted the extra MPs, shutter speed, and rear display panel adjustability and touch screen. Picture quality is great as always. Glad I upgraded and didn’t disappoint. Worthwhile upgrade if you are deciding on a new camera and have the budget.

Rated 4 out of 5 by from Please fix the overheating issue I bought this camera and I'm actually really glad that I bought it. The only thing is on my first time use on a video project the camera overheated and I was unable to use it. Took me two days to figure out exactly how to not get it to overheat as much as it did. Sony, I respect you as a company but please do not release a product that you know that overheats. Resolve those issues on the front end so the customers are happy. Outside of the overheating issue, it's an awesome camera I'm glad that I made the investment but I wish I had not almost been embarrassed due to my camera continually overheating and shutting off during a video shoot. I am glad I had my a6300 as a backup. If you're doing photography and short term videography it is a great camera. For demanding video work, make the adjustments in the settings menu so that the camera does not overheat as much. I have faith that Sony will be working on a firmware update or something to resolve the overheating issue. I would hate work for a company that would release a product knowing it has issues and do not resolve it before release. No manager, CEO, Board Member or anyone would be happy making a purchase and then find out it has problems.

Rated 2 out of 5 by from Annoyed The Raw Image quality don’t work and keeps giving me a error message This operation or setting not available as follows and well as the Noise Reduction. So now I have to send the camera back and wait for a new and hope it Dont give me the same issues. The camera does take nice photos so far but this is annoying only had the camera for a week. And customers service was rude tech support was no support.

Rated 3 out of 5 by from Beware of Overheating Issues. I want to love it but, while setting it up along with a YouTube video last night it overheated in an hour and turned off. Had to extend the overheating threshold. This was without videoing or taking multiple pictures. Just set up, I want to love it but this frightens me. Hopefully this can be fixed with an update SOON!

Rated 5 out of 5 by from Great Service This is my second big purchase from focus. I purchased the Sony a7iii about four years ago and now the Sony a7iv. Super fast shipping received the camera in three days. Ordered it on Friday night received on Monday. And of course, the camera is amazing!
