Great tool for your Digital Cinema Camera

I am around a lot of crews that are using digital cinema cameras of different types. Sometimes they are surprised when I pull out a SensorScope. This is the modern day version of "checking the gate" to me. It is a magnifier that lets you look at the sensor, more accurately the OLPF glass in front of the sensor. There are kits available that include swab wands in sterile type bags and a simple hand blower-bulb. They were made for digital still cameras but they work great for cinema style CMOS cameras. It has a built in light to illuminate the body cavity also.

I check the sensor during prep and if I am outdoors in a dusty situation I will check during the shoot day as well. Usually the hand blower-bulb gets most of what I notice. This is the brand I have been using, I know there are others available but this one has worked really well for me. They are pretty reasonably priced I think a kit is under U.S.$100.  It is piece of mind, not having some out of focus crud in your images. It surprises me when I meet people who don't have one of these.
