Switching lenses with camera on?

[Lars Wikstrom]

Hey, still getting use to my first Red camera. Normally my DSLR's I would power down and switch lenses since it only takes a few seconds to power them up. But the Komodo takes some time to boot up so I thought I would check first if it is OK? Thanks.

It's totally acceptable to swap lenses with the camera running. In fact, the quicker the better or you'll have a very upset AD breathing down your neck!

[Lars Wikstrom]

Good to know, thank you. Wasn't sure if it would harm the sensor or not.

[D. O'Bryan]

No problem! Just be careful as you're swapping and don't let anything but the lens in there! But that applies to any camera.

No problem, this is standard on cinema cameras, there's no point it off.

I assume that there is no risk of getting dust on the sensor?

Why would the risk be more or less based on if the camera is on or not? Look at pro photographers who swap lenses all the time, fast and pretty roughly when hunting those perfect moments.

Problems with sensors rarely come from dust and physical stuff but most often from bad electronics, dead pixels and other stuff internally. I've rarely seen a sensor break down by anything else than bad manufacturing.

I also have on Pre Order the drop in filter from https://breakthrough.photography/ This will offer a level of protection too, when it arrives. Thanks!

Because when the camera(sensor) is on, there is basically a static charge across the sensor and particles, dust, etc. are attracted to it and land on the OLPF. It may have been the original C500 or PL mount C300 that had a button that basically shut down the sensor so you could change lenses without shutting the entire camera down.

And I would never take operating technique from a still photog and carry it over to motion. I’ve spent my entire career shooting next to still photogs in the sports world. Half of their time spent in post is cloning out spots of dirt from their filthy lenses and sensors. One of my friends(still photog) was giving me crap one day telling me I had the cleanest lens he had ever seen. Which isn’t really a major accomplishment when compared to how they treat their lenses.

Good points there, Christopher. It's also worth pointing out that some cameras have an anti-dust feature.
