I stayed up late last night to capture nearly 300 Sony a1 noise and dynamic range test images. The non-lossy compressed RAW file format seemed a no-brainer to reduce the storage requirements (all of our test images are archived).
| Model / File Size in MB @ ISO: | Sony a1 Lossy |
|---|---|
| 12800 | 54.7 |
| 25600 | 55.6 |
| 51200 | 55.6 |
| 102400 | 56.4 |
How big are raw files on Sony a7iii?
Regardless of the ISO setting used, the a7 III uncompressed RAW files weigh in at about 47.3 MB. The compressed a7 III RAWs are about half as big, each being about 23.8 MB.
How much space does a raw file take up?
A RAW image file roughly works out to be around the same size as the number of megapixels of the camera – so for example, a 20 megapixel camera will save a RAW file of around 20 megabytes.
How many MB is a raw file?
Most RAW files are sized between 20 – 40 MB per file.
Are raw files big?
RAW files are larger than JPEGs since they retain much more data. A 16-megapixel camera will deliver a roughly 16 MB RAW file. RAW files are read-only files.
Should I shoot compressed or uncompressed Raw?
Lossless Compressed Raw is recommended when you want to record content in a higher image quality equivalent to uncompressed RAW in a smaller file size format.
Why are raw files so big?
Raw files from your camera are very much larger than jpegs output by the same camera because raw files are the literal raw data captured by the sensor. The raw data is unprocessed and usually uncompressed. It must be processed to be usable.
How much storage do you need for 10000 photos?
| Number of pictures | Memory needed for 2MB pictures |
|---|---|

How big is a 20 megapixel RAW file?
about 20 MB
Raw photos are generally about the same as the megapixel rating for the camera. For example, a 20 megapixel camera creates raw photos at about 20 MB in size. There are other cases where the file size can be much larger than the image size.
Is DNG better than RAW?
DNG files are generally 15-20% smaller than RAW files, but the difference in quality is minimal. A DNG file can also save the original RAW file within itself. This doubles the size, but is also a nice safeguard. DNG files also strip out select information to decrease the size and simplify storage and editing.
How many RAW photos can 32GB hold?
2,228 RAW photos
RAW File Size
A 32GB memory card can hold a maximum of 2,228 RAW photos with 4 megapixels. If the RAW images have 22 megapixels, a 32GB card will only hold 416 photos.
Does RAW take more space than JPEG?
RAW images take up much more storage space than JPEG images. This means that your memory cards can store fewer images and your camera buffer can quickly fill up, causing the camera frame rate to drop down significantly.
How many RAW photos can 128GB hold?
4,300 pictures
RAW File Size
RAW files on your camera are typically much larger than JPEG files. Because of this, you won’t be able to store as many pictures on a 128GB hard drive. The average uncompressed RAW file is about 30 MB, which is about the size of a high-quality JPEG. You can fit about 4,300 pictures in 128GB of storage.
Do raw files get smaller when opened?
Raw files are larger because they contain a lot more information compared to JPEG files. JPEG is a compressed file format. That means that in order to get that smaller file size your camera is literally throwing away information.
How big are Sony a1 RAW files?
At ISO 100, the Sony non-lossy compressed RAW format results in a huge file size reduction. This file is 63% as large as the uncompressed result, and similar in size to Canon’s standard non-lossy compressed 50MP EOS 5Ds R RAW files.
| Model / File Size in MB @ ISO: | Sony a1 Non-Lossy |
|---|---|
| (MP) | (50.1) |
| 100 | 64.0 |

The files are generally used for editing and exporting into compressed image formats like JPG, GIF or PNG.
Is Sony compressed RAW lossless?
Sony doesn’t offer a lossless compressed RAW file unlike every other camera manufacturer. This makes me incredibly mad! The lossy compression scheme works very well for saving space. My 42 MP files from my A7RII camera take up on average about 43 MB per image or about 1MB per megapixel.
Does Sony A7IV shoot RAW video?
10fps is the same as the A7III, but behind the Nikon Z6 II which shoots 14fps, and way behind the Canon R6 which shoots 20 with the electronic shutter. The A7IV only shoots 5fps with lossless compression or uncompressed RAW.
