Photographic Solutions E2 the highest purity tin oxide sensor cleaner contains less than 5 parts per million (ppm) of contamination (the whitish residue left after evaporation). This cleaner is recommended for both tin oxide CCD and CMOS sensors.

It works best when used with Photographic Solutions "Sensor Swabs" (sold separately).

Note! E2 is also good for the Canon 400D; it's not recommended for critical optics.
