Ok, if you're looking at shorts (for now) you will be thinking of a large sensor camera. I will touch on the first paragraph in the 'Camera World' thread.
The Panny HMC150 isn't a bad camera but with a 1/3 chip you'll never get a 'filmic' look unless you -
A) stand 5miles from your subject and zoom all the way in
B) Use a 35mm adapter - negates the point in this day and age; 4yrs ago YES, today NO!
Seriously, if you don't yet own a camera and want to shoot 'shorts' or even a 'feature' (depending) go all out 'indie' and get the hang of a DSLR.
On the second part of your second paragraph I try to explain what I think you were saying/asking -
Not just Canon but DSLRs in general are very good for lowlight shooting BUT because they are we tend to forget we SHOULD still light scenes - even 'dark' scenes.
DSLRs are cheap and can deliver a very 'filmic' look straight out-of-the-box even with the crappiest, cheapest lens on the planet.
All light going into any camera can and should be controlled by the 'shooter' - DSLRs do NOT have built in ND filters so having a
'Vari-ND' is practically a must if shooting in bright dylight (the link is reference sample ONLY as you can see they come in various sizes depending on the lens you want to use).
One problem some people run into is not using the 180 dgree shutter speed rule which is can make video look really weird when using DSLRs (and other cams too). So in bright daylight you need a way to shoot at the 'apeture' YOU want (depending on the look you are going for) and a way to cut down the light going into the camera. For stills there is no problem changing the shutter speed but for video - that is a problem!
You're in the US at the moment right? That's NTSC land - you guys shoot 30p & 60p because the electricity there is 60Hz. UK and Nigeria are pal so we shoot 25p & 50p as 50Hz electricity. Same thing goes for 'interlaced' rates. For a cinema film you'd most probably be shooting at 24p.
So back to the lght thing you can change your shutter speed in 'mulitples' of the rate for whatever country you are shooting in... especially if you notice 'flicker' from the artificial lights.
The 180 degree rule applies to video/film in that shutter speed is approx twice the value of your frame rate. So let's say you are shooting 24fps then the selected shutter speed on your camera should be 1/48th but many cameras dont do that... the next closest is 1/50th. If your shooting 30fps (NTSC) then your shutter speed is 1/60th - this 'rule' keeps a 'filmic' look. Again the problem is, especially with DSLRs, how to keep that rule with your chosen appeture in bright daylight? The sole reason every DSLR shooter should always have a Vari-ND. It solves the light issue you were talking about.
Hopefully that's what you meant??
DSLRs do have a big learning curve if you want to use them very well. I think they are worth it because we have never been able to get a 'filmic' look out of ANY camera for 'peanuts'.
And also remember 'dual-system' sound is a must too!
