170 hpx versus ex1

I can smoke, drink a beer, work a dip cup while driving a stick shift holding an hvx out the window (without a film permit which is VERY serious in my town) and not get thrown in jail... - knocking on wood right now -
 
Which one of this two cameras do you think can offer a more "film look" and which one is more low light capable?

And the last question: there are problems to shoot with the EX1 in a room with neon light?

Perrone answered this one well.

They are the same, unless you want to shoot in interlaced 1080/60i. In that case the EX1 is more low-light capable. But in 720p or 1080p, the EX1 and HPX170 are fundamentally the same sensitivity and same noise levels.

Haven't tried it. Don't know if the rolling shutter would cause an issue there or not. It can cause issues with fluorescent and HMI lighting, but I don't know if or why there would be a problem with neon lighting.

Barry, about 90% of my work is under fluorescent lighting. I haven't seen any issues yet. Can you tell me what the problems might be?

To be more specific, nearly all my meeting, conference, and seminar work is under office fluorescent. My primary keylight is a Rifa88 with the 3 CFL fixture. I just haven't seen anything weird. Maybe I'm just lucky?
 
It depends on whether you're using an electronic or magnetic ballast fluorescent. Electronic high-frequency ballasts are fine. Under magnetic ballasts you can get rolling/scrolling bands of orange in your footage, depending on your shutter speed. If you're using 1/40 or 1/60 you should be fine under magnetic ballasts, but under 1/48 you'd see a slow-moving rippling texture to your footage, and with a shutter of 1/200 or shorter so you'd see thick orange bands scrolling through the footage.

Same with HMIs. Magnetic HMIs cause the above issues with a rolling shutter (or read-reset shutter, as Red calls it, and yes it happens on Build 16 with a Red). But electronic ballast lights are largely immune to causing these effects, unless you use an extraordinarily short shutter (like 1/1000 or so).
 
Interesting. I'll fire the camera up on Monday when I get to the office and see if I can see these effects.

Indoors, I normally shoot 24p with 1/48, 30p with 1/60 or 60i with 1/60. Outdoors, it depends on what I am doing.
 
"film look" .... I mean:

If I shot in 25p, which one camera look more close at a 35mm movie (a movie broadcast in tv)?
 
While I would say that both cameras, if shot like a film camera (lighting, camera movement, composition, etc.) can look very film like, the HPX will win the battle as it comes from the factory. The EX1 needs to be adjusted quite a bit to get that look. However, the EX1 *CAN* be adjusted quite a bit more than the HPX and in finer increments.

Some will say the HPX has a certain look to it that the other camera will never achieve, and that may be true. The reverse is also true. The HPX cannot replicate the look of the EX1 for various reasons.

Both are excellent cameras, and both can produce stunning images. Far beyond what we had just a few years ago in this price range. So, you pay your money, and you make your choice. :)
