Some screen shots from my ex3...

1080/24p
ND2
M gain(I think thats 9db if i remember right)
NO PP
1/48 shutter

I think thats all the info. If i'm missing something let me know.
 
They use to call me care bear.
and yes fish do get thirsty that's why they live in water.

Anyways really sharp pics love the detail.
 
Nice shots. Do you have any idea if when using a normal 2/3rds inch mount Fujinon lens and the adapter, does the lens get power for the zoom motor and auto iris?

thx...jw
 
Nice grabs, but how about a Vimeo video?

Have you considered buying a different glass for the EX3?
What made you choose the EX3 over the EX1?
 
I cant put the vimeo up until I turn the video into the client.

Not sure if this is accurate, BUT I think that the if the gain and the nd are on it can give you a more narrow DOF. So I tried it out. not sure how i feel about it.

I got the ex3 because i do a lot of handheld. It is a key part of my business. Thats about it and its the latest and greatest right now. I also like the idea of being able to swap lenses down the line.

I have only been looking at adapters. Nothing crazy. I read on some forum that letus might make a adapter that goes direct to the body...

No.

Narrow depth of field comes from using large aperatures. Like F1.9 to F2.8 our our cameras. So you use ND to reduce the light coming in so that you can open up the iris. Adding gain does nothing but degrade the picture, so you only use it if you MUST in low light.

Yeah, but adding ND could mean in some situations, that even with the iris full open the picture will be underexposed.
So you could actually bring up the exposure to a acceptable level by adding gain. As you said this will degrade the picture...
 
Gain increments are as small as one stop (3dB) depending on the camera settings, and ND filters are three stops. So to get the lens wide open (a perfect f/1.9) at a given light level, it's not inconceivable to have to add an ND filter and then add a stop or two of gain back.
 
No, not inconceivable, but looking at the material here, we have essentially non-moving subjects outside on a sunny day. As I said, I was just curious. 9db of gain is a pretty high amount.

Personally, I would have adjusted the shutter first. But that's just me.

I agree with you in this case. 9dB is three stops, which is the same as one ND click. I would just eliminate one ND and put the gain to 0, of course.

I was just speaking in general terms.
 
Usually, a dB of gain is considered equivalent to 1/6th stop, or 6dB of gain as a full stop.

If you have a polarizer in your kit, you can use it to pinch-hit for a .6 ND (two stops), if you're trying to be more precise.

For fine-tuning I would go with PerroneFord's suggestion, tweaking the shutter. Gain is best left as a last resort.

Actually, 6dB equals 1 f/ stop. So 9dB equals 1.5 stops.
 
It's certainly not inconcievable, but it doesn't really make sense to me to do so, and certainly wouldn't recommend it, unless you intentionally want to introduce noise to the image for effect. I personally would do that in post, that way you are not locked into an effect that you may not want later on. If using the gain didn't introuce noise and degradate the image, then yes it would be a legitimate method. Unfortunatley, gain does introduce noise, even at 3db, and obviously more at 9db. I never use any gain...it is really more of a news type function when shooting in extremely low light situations. I do mostly commerial production and own a 5 ton grip truck so it really never is an issue with me. That is why you should have a set of ND filters, using the optimal ND or combination of ND's to achieve desired stop. You don't need to shoot the lens wide open to achieve a shallow depth of field. Any stop under 4 is going to give you a pretty shallow depth of field. Not all ND's are 3 stops, an ND 1.2 is 4 stops, an ND9 is 3 stops, ND6 is 2 stops and a ND3 is 1 stop. At sunny 16, you should be able to acheve a shallow depth at a stop around 2.8 by stacking a N9 and a N6 (5 stops) Starting at 16, count down 5 stops...11,8,5.6,4,2.8. You could achive the same effect by using a ND 1.2 and a ND3. Keep in mind with some of the new video technology there are some IR issues when stacking ND's. If you plan on using this method alot it would be worth investing in or renting Pancro IR ND's (or at least a N3 for the front.) which deflect IR. You also need to be carefull stacking these filers. You do not want to put an IR ND behind a regular ND. Make sure the IR ND is the front filter. So you really shouldn't have to worry about using NDs and under exposing the image, requiring you to add gain to get back to stop. Happy shooting
