Originally posted by MMVIII I wanted to add that all Pentax I dealt with (Q, KP) offered to save the last image in the memory additionally as a raw by pressing OK in the view mode (IIRC). This might be a welcome addition to this setting if some individual images are taken inbetween an one wants to add some raws without changing anything (and forgetting to put it back).
That's a really good thought! I've seen it before - much like how you can change white-balance and save the most recent image. It wouldn't always be useful with the RAW, if you're in a busy shoot, but for a casual shoot if you get an awesome image it'd be very nice to get the RAW file if desired that way!
Of course I always shoot RAW to both cards, but I'm considering mixing it up to try and limit my buffer woes.
