It boggles my mind that Sony engineers would think this would be a good idea at all to waste so much space and CPU time. I bet this is one of the reasons that the Alpha 1 can't actually do the full 30 fps with tracking as shown in the Mark Galer review. It could only do 26.6 fps with tracking and you have to drop down to wide area - no tracking in order to do 30 fps. The CPU is wasting time creating full size JPEGs instead on AF! This is just so plain wrong and absolutely unnecessary for a sports camera! 5-20% of the Sony Alpha 1 RAW file is just a waste of space and time.
I guess only a waste of space and time if you don't make use of embedded jpegs. But a lot of us have wished for a full size jpeg since the beginning of Sony MILCs. So I'm happy. Canon and Nikon have been doing this forever. Having this full size jpeg is going to speed me up since now I don't have the camera writing RAW+Jpeg which is surely slower than writing just RAW with a full size embed. Considering I'm not jumping down the CFe-A hole until it makes financial sense, this should help my use of SD cards also.
The average size of the Alpha 1 RAW files with compression is 57 megabytes. You are not saving any time or space with Sony RAW files that big.
Sony A9ii compressed RAW files are 24-25 MB. The Alpha 1 raw files have double the resolution but are 1.28x bigger in file size. That means the Alpha 1 RAW files are 28% less efficient!!! And all because of those dang full size JPEGs no sports shooter wants.
