I have 7.1GB space left according to ML.
One DNG raw pic needs 3.9MB according to my file browser
The memory calculation of the intervalomater prints 217 pics are possible.
7.1GB ≈ 7240MB
7240MB : 3.9MB ≈ 1855
I guess since DNG is possible most people will use silent pics for timelaps.
Intervalometer calculation is based on Canon file size report.
