In Topic: Upcoming Panasonic GH-4K

01 August 2014 - 10:39 AM

Hi Jean,

I already invested in a Zen 8 inch dome with an Aquatica mount, can I use the same for your GH4 housing?

I have the panasonic 7-14 and contemplating to buy the faster 12-35mm 2.8 cause it's faster. Is the above dome good for such lenses?

Thani, have you thought of using the 4k on Youtube?  The Vimeo 720p just destroyed the video.
 
The topside shot at the end was very nice.

I have rendered it only at Full HD 1080p via resolve. Make sure you play it at Full HD resolution. Vimeo does a good job preserving the video especially when H.264 is used as a codec.

I think youtube compression is much more worse and 4k would be very heavy I thought.

The same version is available on YouTube:

In Topic: small hd dp4 or dive and see dnc-7

25 July 2014 - 10:41 AM

I am currently looking for a external monitor solution for my bmcc.
It seems like right now there are only 2 options available. Either a nauticam hausing for the smallhd dp4 or an external monitor from dive and see.
 
Does anyone have experience with both monitors, or can recommend other monitoring solutions? 
 
Since it's mainly to be able to do critical focus I am right now favoring the dnc-7 because of the bigger screen size, but I haven't found much information on actual screen used and screen resolution.
 
Thanks
Nihal


From my experience with the 1.8 firmware hence it brings GREAN color peaking for focus & the one touch auto focus you don't need an other monitor to achieve good focus. Actually I I find the BMCC is better than the Ninja2 dull screen.
All you need to do is:
Set Monitor to video (this has nothing to do with Recording format) only for monitor,
Get a good shade or make your own for the BMCC monitor,
Set peaking by pressing focus button twice - pressing once is auto focus function
Set highlight if required

BMD already released version 1.9 that has a histogram for the BMPC 4k and the BMCC should follow soon.

Unless one wants to record proxies at the same time, having an external monitor is not helpful for the BMCC setup. I don't know if you can record at the same time when you press the rec button on either BMCC/Ninja. BMD cameras don't send any triggers to recoding devices via hdmi or bnc :(. May be a loop through the LANC - may be - could help. Must be tested first.

Doubt a flip diopter would work as the lens front element moves when you zoom, but I don't know. I would almost always light a macro subject, but that's just personal taste.


What was I thinking? The lens moves when zoomed. let's forget about the inside flip diopter :)
Thanks Jonny, I appreciate your help.

I don't think it would vignette on the Blackmagic camera as it is designed for APC sensors, I like the lens, it is sharp, not Zeiss sharp but pretty bloody good for the money, its 2.8 at the wide end and it does have IS (although won't work on my RED). I use it behind a 8" dome and get pretty good results. The real selling point of this lens is just how versatile it is.
 
No idea about swivel diopter?

I meant a close-up lens that sets inside the housing which can be swiveled in front of the sigma lens when doing macro.
Do you think artificial lighting is needed when doing macro with this lens?
