Lens Changes
Hello,
Is the SI2K meant to operate in a way where lenses are changed often? My question is related to possible dust on the sensor. With DSLRs, changing lenses too often can lead to needing to clean the sensor often as well. How does the SI2K act in this regard? Thank you |

There was a discussion about this subject on CML. It seemed to conclude that cleaning the sensor on cameras like the SI 2K and RED will have to become a routine operation like checking the gate on a film camera.

Cleaning is not that big of a problem if the sensor is protected and was designed to be cleaned easily.

Yes, you can easily pull off the low-pass filter if you need access to the sensor itself. Cleaning that is a matter of using some good lens cleaning fluid on *dampened* (not wet) lens tissue.

Hello Jason.
So the sensor cleaning is not as delicate as cleaning a DSLR sensor where a lot of people say not to even touch the sensor? Thanks |

There's a piece of solid glass in front of the sensor itself . . . I'd still be very gentle, and only use somethign as soft as lens cleaning tissue and have it ONLY DAMP (so you don't drip anything), but it's not like touching the sensor is going to cause harm. I've cleaned the sensor itself many times and have had no issues.

for what it is worth, I've had to clean the sensor initially after receiving it (mine is a preproduction model that I got back in December), but I'm very pleased with the lack of dust since. It has undergone frequent lens changes on a dusty set without being covered (between lenses) for three weeks, and less rigorous shooting indoors and outdoors since, and I haven't had any dust return. Not sure why, but I'm quite pleased.
