Yeah, nice clip but I am not impressed by the stability. Very shaky. But it's one clip, not a video.

GH4+Nocticron 4K Video

Here's a short video shot with the GH4 and the Nocticron as one would normally shoot a video, in shutter-priority mode (1/60th for 4K 30p). It was shot at dusk and with an .8 ND filter to open the aperture. Handheld to test the OIS using my best technique (viewfinder), and close-ups to test the bokeh. I used autofocus, and you will see why you want to focus lock (which I normally do) after autofocusing.

Some video frame grabs:











Of course, the Nocticron is an ideal portrait lens. But I do not know anyone who wants to have their face posted on the internet, for free.

The Leica Nocticron Lens Belongs in a Museum

In museums light is the enemy of artifacts, so they are dark. Perfect for a fast f1.2 lens. Handheld to test the OIS. Close-ups to test the bokeh and focus.
Dinosaurs, dioramas, lizards, lectures, gemstones, mummies, and even a ghost. Plus a trip to the museum store.
Shutter-priority at 1/60th.

Handheld shooting does not work well for the GH4 - there is constant horizontal - only! - shake in all the shots.

There is some noise in the mid-tones on GH4 4K, but applying a little temporal denoising using the Neat Video plugin on these clips removes this for a totally clean image.

I also tried a bit of sharpening on jogiba's clip, but to my eyes this produced an unnatural-looking result - it is sharp enough as it is.

SLR Magic 10mm T2.1 on GH4 in cinema 4K !

Quote:
SLR Magic 10mm T2.1 on GH4 4K and 96fps 1080p mode
I've just received on Wednesday the upcoming SLR Magic 10mm T2.1(eq. f1.8), and their upcoming variable ND filter ! (released in october 2014)

My very first impressions : solid, heavy (420g), compact, sharp at full aperture T2.1, only 2cm minimum focus distance.
The ND filter : good first impressions, and two great options on it : lever and hard stop ! Perfect for video !
SLR MAGIC 10mm T2.1 (f1.8 eq.), most of the clips @ T2.1
SLR Magic ND variable filter
GH4 4K cinema mode + 96fps 1080p mode
Vcine mode with Andrew Reid presets (eoshd.com)
No color correction

The Leica DG Nocticron 42.5mm f/1.2 is for sure a great piece of glas - does the autofocus of the GH4 work with that objective?

Kind regards,

Yes. And so does image stabilization. Just a little over 1500€ at Amazon Deutschland.

The AF and IS works great on it.

From 43 rumors - GH4 firmware upgrade tomorrow - please take with a grain of salt - but if true, would be terrific news for GH4 owners:

“Panasonic new firmware will improve 96fps slow motion and the 4K mode. Including internal compressed raw, 12 and 14 bit uncompressed hdmi”

Interesting that you point out that Samsung's cash flow from Smartphones can fund their 4K TV production that will facilitate the inclusion of 4K capability in everything Samsung makes.

Nikon has a market cap of about $6B

Panasonic has a market cap of about $28B

Canon has a market cap of about $44B

Samsung has a market cap of about $187B.

If they decide to go all out and crush these companies in the interchangeable lens market niche, they can.

Users can record high quality video either in 4:3, 3:2 or even 1:1 aspect ratios in addition to 16:9 – all can provide a still image with 8-megapixel equivalent resolution. Each JPEG image cropped out of the video footage complies with EXIF just as a normal still picture. While recording the 4K video in 4K Photo Mode, it is possible to mark the designated portion by just pressing the Fn1 button. This can reduce postproduction work for searching the spur-of-the-moment worth cropping out.
I think that's pretty cool. That way there is a way to 'bookmark' where (approximately) you want to take your screengrab from for the 8mp still. And the rolling 2 minute clip thing could be useful for something like wildlife photography if you don't have the 'imaging app'....which I don't because panasonic hasn't released a Windows Phone version of it!!!

A billion here. A billion there. Pretty soon you have some real money. Even at $6B, Nikon is a long ways behind. I had no idea. As fast as tech stuff changes, Nikon could be borrowing their slippers from Blackberry!

Samsung certainly makes good refrigerators, clothes washers, clothes dryers and smartphones. I have those. Perhaps a Samsung camera is in my future. But, now with three Lumix lenses, it may not happen.

Maybe the Samsung menu would be easier to learn. The Panasonic menu learning curve still sucks after 9 months.

The GH4 Has the Advantage of Many Lens to Choose From

There are examples above of video using the Nocticron lens. Here is another garden 4K video shot with the GH4 and the 35-100mm lens, taking advantage of the reach and the shallow dof:

My camera lust comes and goes like the tide. The GH4, Lumix 35-100 F2.8 and the Lumix 12-35 F2.8 is a $4K 4K video and photo kit that pushes my buttons pretty hard. The AX-100 triggers a little bit of lust, but not nearly what this does.

Thanks for posting the examples and fueling my imagination.

Of course, to be fair, the GH4 requires several lenses to duplicate the range that already exists on the AX100. Yes, the focal length range and lens speed can be greater if you invest in enough lenses, but you have to be willing to make that investment and (more importantly in my case) be willing to schlep these lenses with you.

We're on a trip now, and I just wouldn't carry multiple lenses.

Ken,

You seemed to like the GX7 until you got bit by the 4K bug and caught the GAS that goes with it!

I do agree with you about packing lenses. However, in my case, there are photography missions and travel missions. I've not learned to mix them well. I'm bad company when I'm concentrating on photography and a bad photographer when I'm being a good tourist and enjoying the sights and culture with my DW or friends.

Therefore, the most productive camera I've ever owned is the RX100 that slips in and out of my pocket and mostly stays on auto. I can get "good enough" snapshots or clips without telling my fellow travelers to stop and wait while I shoot. I can do that about twice a day before someone gets POed. If my DW parks me on a bench so she can shop for sweaters or purses, I can switch to more serious photo or video settings. And, I can easily get away with shooting the natives because the tiny camera does not threaten.

If I do go on a photo mission, I can pack the monster GX7, gargantuan long lens and massive tripod. Rather than carry any other lenses, I stuff the RX100 in my pocket.

BTW, I do enjoy the GX7 and it was your nudge about video quality that helped me get past my reluctance to spend money. The "kit lense" stays home. The "regular" lens is a 14-140. The special lens for National Parks is a 100-300 that requires a tripod and sucks for travel.

Someday I will get past my reluctance to spend money and move to 4K. You may be on 16K by then!

I hope your trip is a good one and your travel clips are stunning.

Bill
