I have no idea, I only have RAW samples from the bracket modes, not from burst modes. DP Review is the one who added that point about continuous drive.

If you can share a RAW sample that was taken during a burst I can check (or you can check yourself using the method I outlined here using dcraw to convert the RW2 to grayscale PCM and the HXD hex editor to check the lower two bits):

What's the best way to send you a raw image? If you PM your email address I can send it that way.

Dropbox link or Google Drive link? Usually email attachments have size limits.

I have just sent you a dropbox link via PM.

Thanks for offering to take a look at this.

Hi Pete,

For this burst image from your G95, I verified it is a 10-bit RAW, just like the bracket files from DP Review. 10-bit meaning a 12-bit RW2 file with lower two bits of values filled with "11" as mentioned in other thread.

Here are the counts for the value of the lower bits in your file, you can see that almost all of them are "11" which indicates it's 10-bit data with lower two bits filled in.

count 00: 117

count 01: 111

count 10: 90

count 11: 20300482

Thanks Jake!

I guess that's unwelcome news and a bit disappointing for G95 owners, but better to know for sure.
