The GH5 Era Begins and the Start of Lots of Updates

So, after a deal with a very dangerous group of individuals, I have finally acquired a GH5. This wasn’t planned to happen for a few more months, maybe even a year… but hey… GH5.

Not having a GH5 is not the reason for the lack of updates. I was very sick over the past few months. Last year a had a bout with vertigo that came back with a vengeance this year. Makes it hard to focus on anything. This was compounded by a list of other problems I won’t mention here. I am much better now. That’s all that matters.

I will go more in depth into GH5 ownership as I go down the road. For now, let’s talk about the two videos I posted recently.

One of the huge differences between the G7 and the GH5 is the 6K photo mode uses the actual full sensor, where the 4K photo mode on the G7 did not. Another big difference is the use of H.265 for these video files, which are a pain in the ass to deal with. However, once the files are properly re-wrapped in Handbrake, you get a massive 4992×3744 video file. When doing my first batch of tests on the first sunny day in awhile (the weather has been horrible since I got the GH5, pushing back planned videos) I shot a few “6K” videos.  Of course I had to do it with an anamorphic attached. After all was said and done I had 20 seconds of 9984×3744 pixels at 14.1 GB.  The only codec that seemed to be able to handle it in Adobe Media Encoder was the GoPro Cineform RGB 12-bit preset. I was using the Isco Ultra Star and the Panasonic 45-175mm zoom, a combination I use for no-nonsense sharp images. It was a successful test, but I think I can do better. I may clean out my work drive and try a short edit of sorts to see how far I can push it. I may even get out the Zoom H2 and do 5.1 surround audio too. Wow.

On to the next…

I picked up a copy of the Möller Anamorphot 32/2x awhile ago, but didn’t get much of a chance to shoot with it. This is a very special lens. I wanted one after hearing you could just screw a 40.5mm step ring on the front and use it as/is. Well, this was the start of a few issues I had with mine. To keep it short, I ended up having to file down the inside of the step-ring to get it to fit right, and even then it took awhile for me to get the confidence to put anything on the step ring. Unfortunately, it doesn’t work to well with the Aivascope Focuser 8. It’s just a bit too long. It does, however, work perfectly with my set of 52mm Nikon diopters. The filter ring also doesn’t rotate when you are focusing, a rarity among anamorphic projection lenses. If you get the custom Redstan clamp for it, it’s a completely trouble-free lens and is incredibly easy to use.

The above video was shot entirely at f/1.4 and double focus. You can use it at 1.2 as well, but my only 1.2 lens is too wide to use the Möller in Anamorphic mode. It’s such a sharp lens… just unbelievably impressive. I am, however, lucky that I can even use it in this state.

When I was cleaning up the lens and getting ready to black out the edges, I had the filter ring completely removed to get at the edges better with my paint marker. However, the lens was set at infinity. And with the top lock collar also removed, a bit of pressure on the top of the lens pushed down the focusing part and the front element…. popped up. It was a nightmare getting it aligned properly again. But as you can see above, I did eventually get it right.

Lastly… having 60fps at 4K is pretty amazing. I will thoroughly abuse this feature. I will also have fun with the other high frame rates… but I already hit a roadblock with those. More on that later!

JSD Labs: Aivascope and Focuser 8 – First Test

Vimeo: https://vimeo.com/214292200

I had a full scale review of the Aivascope planned. And then this happened:

It was the middle of my shoot day. I was taking off the Magfilter when it slipped out of my hand. Only fell 10 cm or so, but flipped on the way down.

Right now it’s on it’s way back to Lithuania to be repaired.  I will continue my tests when it returns.

As for the video above, I wasn’t planning to make a video with those shots. But I had to put together something while I wait. It’s not the best, but I’m happy with what I got.

First, a few quick things about using the Aivascope and Focuser 8:

  • The Focuser 8 is CLEAN. I sold my Elmoscope-II rig mostly because I never grew to love the SLR Magic Rangefinder and it’s random blue at all the wrong moments. I hope to try it out on other lenses when my adapters arrive.
  • The Aivascope is very difficult to use on anything that isn’t wide or small sensor by itself. I have the focus-through version. However, it shines with the set of vintage Nikon 52mm diopters I got for it. Diopters make it very usable, but the Focuser 8 is what makes it awesome.
  • The Aivascope works on the Sony RX100 IV. I need to make a stable rig to utilize this better. I don’t want to have another drop.
  • The Aivascope works on the iPhone 7 Plus with the zoom lens. Even in 4:3 mode using Mavis. Will shoot with this soon.
  • The Aivascope has pretty bad anamorphic mumps when using the wider end of it’s ability. This can be fixed with the AMC plugin from Tito Ferradans and Lucas Pfaff.

As for the video, I shot it on the Panasonic G7 at 1080p 60fps, with the exception of the first and last shots, which were shot on the Sony RX100 IV at 120 fps.

The first half of the video was shot using the Sgma 30mm 2.8 Art on a Beholder DS1. I still didn’t have the kinks of my custom PID settings worked out, so I did use Warp Stabilizer to smooth out a few bumps. Overall it worked. Once I get the combo right (and a camera with IBIS) it should be super smooth. The second half was shot on a monopod and with the Panasonic Leica 42.5mm 1.2. Because of the size, anything below f/2.0 doesn’t register a change. (It gets kinda dreamy below 2.8 anyway)

If I still had the lens I would have shot a grid to get the right AMC settings. Had to eyeball it for this video.

More to come! Let’s hope it returns soon.

JSD Labs: Anamorphic at f/0.95

(Vimeo)

One thing that I learned since getting into anamorphic is that fast apertures and anamorphic adapters do not mix. Most adapters will rarely work faster than f/2.0, with a lot of them going around 2.8-4.0. The fastest full anamorphic lens ever made is the Panavision 50mm f/1.0. Well, I think my 17.5mm f/0.95 has it beat.

My anamorphic is an unbranded 1.33x from the 90’s. While it may look like something from the Century Optics line, it’s more similar to the Sony VCL-W169. I have modded it a bit and it now has a filter ring, and have cleaned the class inside and out. I personally think some of the shots I get from it are better than the Century Optics stuff I have seen online. But as of now I have only tested it against the SLR Magic Anamorphot. Against the anamorphot it has it’s minuses and pluses, one of the big positives is that mine is smaller and doesn’t really vignette at all with the Voightlander. At night you can’t even really tell there is any vignette at all, especially in 4K.

I had been wanting to shoot a real test with this combo for awhile. I had done some test shots comparing it to the SLR Magic (may post those later) and various other things, but I really wanted to wait until I could get it on a GH4 or GH5. Got tired of waiting and my friend Yumiko was free to help with shooting, so I figured I’d go ahead and do one.

I shot at mostly 200 and 400 ISO, with maybe one shot at 600. I had planned to shoot the whole thing at 60p, but I had some issues with flickering at a shutter speed of 100 at random times, but I think it depends on the lights (It was really odd and random) so I may do another one all at 60 fps later. The under-cranked video was done at shutter speed 2 and then sped up in post. I also experimented with interpolating the 30 fps video to 24 fps, which worked nicely.

Used a +0.50 diopter for most of the shots of Yumiko. I think I used a +1.0 one time and then a +3.0 for the flowers at the end. I used a variable ND filter for the under-cranked video.

I told her we’d only be an hour. I didn’t want to spend all night composing a few shots. I wanted to see what I could do run-and-gun and then evolve what I learn for projects later. The +0.5 diopter really is magic… It’s what makes most of these shots possible. But even with it’s razor-thin focus, shots without the diopters can be just as sharp after a few meters or infinity. My only regret is that I didn’t go the extra mile and set up the Beholder for this rig. I didn’t give it much thought at the start because I had orignally planned to shot 60fps and thought it wouldn’t be and issue. Walking with that rig wasn’t too bad either way.

Lastly, I tried Speedgrade for the first time. I am usually horrible at color correcting, but I think I’m finally getting somewhere in Speedgrade. I decided to try it out to help simplify my workflow and it worked very well. I’ll do a few practice videos this week and watch a few tutorials to see if I can improve even more.

I have been shooting a lot lately, but nothing really complete. Just really trying to master what I have, or at least figure out how to get the best out of it. Might have to change a few things to get where I really want to be. Stay tuned…
