This is only mostly true because it assumes all other factors are equal. Before I knew we were going to be online-only this year, I was doing a lot of research into video cameras (mostly camcorders rather than DSLRs). Of the couple that I was narrowing my selection down towards, it was interesting to note that the larger 1" sensor options had slower lenses with less zoom range than the comparable cameras with 1/3"-1/2" sensors. If you do the math, the theoretical light gathering capabilities of the two types were pretty much the same because of the lenses. At that point, any difference in performance comes down to the quality of the sensor and image processing software rather than the obvious physical specs. That's the sort of thing you can only know for sure by getting a demo.Basically, you want a bigger sensor to be able to handle low light and by being a distance from your subject.
This is definitely true for consumer camcorders, but moving into the low end of pro, or more "prosumer" level is more likely to give you this as a physical control. I was aiming for the $1500-2000 range, so the Canon XA50 and Panasonic HC-X1500 were two of the top contenders. The Panasonic has two rings: one for focus, and one that can be either zoom or iris. The Canon just has a focus ring, but iris can be assigned to a knob... not ideal but still usable. That's more expensive than just the body of a DSLR or mirrorless camera, but when you account for quality lenses to get the same range of capability it's either a wash or less expensive to go with one of these camcorders.Part of the problem with camcorders I find is a lack of control of the exposure in video mode
Sorry I missed the budget.. I probably spent about 400 for the Nikkon, and it came with both a nice long lens and a shorter more standard lens. For folks like me at the low end, it was like I died and went to heaven.This is definitely true for consumer camcorders, but moving into the low end of pro, or more "prosumer" level is more likely to give you this as a physical control.

Of course, I'd much rather have $10-20k to spend on each camera, but within the budget I have, something similar to the two I mentioned feels like the best compromise to me.
Have you used the Studio Cam in a theatre setting? The overall design of it is really appealing, but I was put off by a number of reviews that mentioned mediocre performance unless you have a lot of light. Well, that and the lens limitations/expense...If you want to spend DSLR money, I'd reccomend a Blackmagic Studio Cam and an ATEM Pro switcher. I know, not a DSLR but the camera can use DLSR lenses. It also has a display with features to assist focus and is 10",big enough to see (not 3" on the sony). The biggest feature is remote image control. This will allow you to shade (white balance and exposure) on the camera from a remote location using a computer. This leaves the operator with 2 jobs, point and focus.
I unfortunately haven't used it in low light, only corporate evenly lit events.
