At these days the card is nearly about the price of a used 7D on ebay.

SanDisk Extreme Pro 256 GB are about 284,- Euro and have a 150 MB / s WriteSpeed. Note: UDMA 7 CF memory card read/write speeds are not fully supported with the EOS 7D Digital SLR camera, if using UDMA 7 memory cards, the read/write speeds will be equivalent to UDMA 6.' '*Figure based on updated firmware, ISO 100, Standard Picture Style and with UDMA 7 CF memory cards. That are about 3000 x 2000 (like the EOS 300D full sensor could do)īut, this datarate could not be done continuous. So 6 Megapixel would be the limit, I guess. For film, we would need 24 Frames, so 3 times as fast.ġ8 Megapixel / 3 ~ 6. The data rate from the Canon EOS 7D is fast enough for 18 MegaPixel 8 Frames a second.

What we don't want is, to have more artifacts.īayer RGBG array per 2x2 Pixels. Maybe we can reduce the resolution a little bit, maybe we could save not every Pixel, maybe we could combine Pixel's luminance. So maybe we can do a compromise, not having 16 Bit per Pixel, but only 12 Bits. So what we want is, to reduce the file-size and memory usage in the Canon EOS 7D's RAM and on the Compact Flash Card for some reasons: Able to store constant / continuous saving of the data stream and. One S-RAW file is about 10 MB for 4,5 MegaPixel. So that could be 1 RAW + 1 JPEG, but the JPEG not at the same time.

Would it be possible, to do JPEG and RAW in tandem?

The 7D can do: RAW: 18M, M-RAW: 10M, S-RAW: 4,5MĪnd at the same time JPEG in L:18, M:10, S: 4,5 BRAW? we would have to encode with an 9 year old ARM chip. Because the MOV-Standard-Codec is not the best. But in FullHD+, 2.5K or so, it would take about 512 to 1024 MB, I guess.
