GH5 100 ASA or 400 ASA in sunny days - video?

Always set your shutter at twice your frame rate. So for 50p 100 shutter, for 24p 50 shutter. Definitely get an ND filter, variable is best for quick shooting.

I see this rule written all over the place and I have to disagree. Yes, if you are shooting 24p, 25p or 30p this is a good rule. In my experience, if you are shooting 50p or 60p it looks best to stay at 1/60th for a smooth motion cadence. 1/120 starts to look staccato to me. I believe this is a "film" rule of thumb and does not apply to 50p/60p video shooting imho.

I would get the large 72mm

Ohhh, thanks for your news. I'd like to buy a Syrp ND filter but I'm noticing there isnt with a 62mm adapter. Do you know another good brand?

Out of curiosity. Shooting in 25p instead of 50p, I will get a better video quality? I don't mean about rallenty but about image quality.
 
You buy the adapter rings separately that go from 72mm down to your lens filter size. Buy the "large" adapter on that website which is for 72mm thread size.

25p or 50p is more about the "look" of the footage than image quality. While 25p can record in 10bit and 50p only in 8bit, this is not the only reason to choose one over the other. Try both out yourself and see how they look on your timeline. Then you have YOUR look for your work.

I agree. The rule I think was intended to ensure that shutter speed was not so fast that the motion was too sharp and stuttered for the slow frame rates. For the faster frame rates this is not so important but the limit I think still applies do not let shutter speed go beyond 180 degrees ( 1/120 for 60P ) or the same undesirable effect will raise its head. You can of course do this deliberately for effect. I shoot 60P ( 59.94 fps ) all the time with shutter at 1/60. I like the smooth motion of higher frame rate and the motion blur at 1/60 is just fine. In fact it will be the same motion blur as if one shot at 30P ( 29.97fps )
 
For you in Italy I would shoot 50P with 1/50 shutter , ISO 400 and use a ND filter to keep F stop around F8. When it gets dark you can just take the ND off and up the gain a little. That way you can get the smooth look of 50P or if you want place in a 25P timeline and get the slower frame rate look and the shutter speed will be correct. The NLE will just leave out every other frame.

I agree with Ron on this. Gives a very nice look.

- Buy a step-up ring from whatever filter size your lens accepts.
- Buy this magnetic filter holder: https://www.bhphotovideo.com/c/product/968073-REG/xume_xla72_72mm_lens_adapter.html
- Buy the 72mm Variable ND.

With this combination, you will be able to pop the filter on and off without taking the time to unscrew. It works wonderfully.

Cool, great concept, never realized this existed!

It sound very interesting but I don't understand fine. Maybe did you attach a wrong link? Both links are the same: what is the right link for "magnetic filter holder"

There will be times when you don't want the image one stop darker. For those times, you need to unscrew the filter from the lens threads. That's time consuming, and a bit difficult since the filter wants to turn. With this adapter you simply "snap" off your filter via magnets.

Sure, I know it. There is a misunderstanding. I asked another question with my bad english. I asked why did you post two same links in the same post. To do all that, will I need to attach another adapter ring on the filter beside that magnet ring on the lens? In other words is it sufficeient only one ring, that is that ring in the link?
 
Fox,

We went over this subject months ago & suggest you re-read your threads.

Back then the Xumes were recommended, & I further suggested you choose a few solid NDs instead of a Variable ND. While Vari-NDs are convenient there are compromises (ghosting/flare, polarization of skin) that are typically not issues with solid NDs.

And since you only use one lens, the 12-60mm f2.8-4, I suggested you choose 62mm filters as the OEM lens hood would help protect the filters from flare, & keep them from getting dislodged by glancing blows when attached via Xume Adapters.

Sound familiar?

Yes Bern, I read about Xume Adapters and you are confirming they are useful for me. I thank you. Do you think this is the right one for my Leica 12-60mm? Look: https://www.amazon.it/Manfrotto-MFX...1530051877&sr=1-1&keywords=Xume+Adapters+62mm
Do you know there is a Xume Adapter from 62mm-->72mm?
I already have a good fixed Hoya 62mm ND filter but if I will put it on the Xume Adapter without screwing it I'm afraid to see garnets at the edges because the filter is too much moved away (distant) from the lens. Maybe I will need a 72mm ND filter.

The issue I have with the Xume adapters is that the act of screwing on a filter was rarely the problem for me in a run&gun situation. The bigger problem was always how to quickly change the filter and store it safely on my body with one hand. Its the safe storage of the filters to quickly grab them that has always been the bigger problem for me. An act that needs to happen sometimes with one hand. The Xume reduces one part of the problem but for me it was the smallest portion of the problem. I almost need a tray in front of me like the old cigarette girls with compartments where I can quickly grab what filter is needed and put filters back in their place. A utility tool belt can somewhat help but its still a bit of effort to fumble around with a secure filter pouch with one hand.

After your interesting reply I still don't understand if you continue to use a magnetic Xume adapters or not. Do you sugget it for me?
 
Then .... I have a curiosity that grips me and I would like a precise answer from those who did the test. As I said, I would like to buy a very good variable ND filter (I already have a fixed one) and I have heard that maybe B & W BW1075251 is the best among variable ND filters. It costs around 200 euros. Since I value the quality of the image, I would like to know how much this filter can degrade the image more than a good fixed ND filter.
 
In my opinion, the variable ND filter will be great for your use. I have used a Variable ND for a lot of shoots and the image looks great. I white balance after the filter is in place to take away any color cast that might be there but with 4k, there is plenty of resolution for a great looking image. The ease of use outweighs any image degradation imho.
