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: IPHONE 7 PLUS NIGHT ANAMORPHIC VIDEO TEST

(vimeo)

It’s been awhile since Mavis updated their app to take use of both of the iPhone 7 Plus’s cameras. I had a bit of time, so I went out to try filming some night shots with the iPhone anamorphic rig.

Some key differences and changes now are better PID settings on the Beholder for this rig, the ability to shut off the OIS, and the ability to lock things like shutter speed and ISO. I wasn’t trying for perfection for this shoot, as I wanted to see what ISOs worked on the iPhone. It’s not really known for clean nighttime video. I tried to remove some of the noise just to see how it looked, but it only worked on some shots. Looked horrible on others.

One of the best things about Mavis is the ability to shoot while in anamorphic mode. No guessing, as what you see on the monitor is what you’ll see on your timeline. And the ability to lock or set pretty much all parts of the camera settings make it one of the best camera apps I have ever used. It switches between the 2 cameras pretty well (it’s not instant, but I don’t mind) and was super easy to use, even with freezing hands in the night.

I decided to lock the white balance at Set 1 (2896k) to try to give a nice cool feel to the footage and to compliment the anamorphic flares. It worked well. Decided again not to color correct the footage so people could see how it looks right out of the app and phone. I am not sure if this affected the amount of grain in some shots, but I can always do another shoot later.

One of the big issues with the first shoot I did with the standard camera app were the distortions caused by the OIS. You can shut off the OIS in Mavis, which is fantastic. But you can tell which shots I turned it off in when I move too much. The Beholder does a great job keeping it steady for the most part, but it’s not perfect. It’s still a tiny rig. I did shoot a few shots with the OIS on, and some are not as obvious as others.

Overall it was a good test. It was my first time using the Mavis app and I really enjoyed it. Shooting at night on the iPhone is not ideal, but you can get some decent shots with the right settings.

I have fun shooting with this rig, but it does have it’s limitations. It’s not really a recommended setup for the average user. I just happen to already have what is needed to do it. I have a bit set aside for the new Moondog Labs anamorphic when it comes out, but I want to find a good stabilizer that will work with it. The smaller and more portable, the better.

But you know what I REALLY want? A basic, small stabilizer for my RX100 IV. Nobody makes one. You could seriously make one the size of the current iPhone and GoPro stabilizers. Somebody get on this.

Lastly, the music was done in the Launchpad iOS app. It’s a nice go-to for somewhat original free music when I have no time to look for something.

JSD Labs: iPhone 7 Plus Anamorphic Video Test

After a week of waiting, I finally received my iPhone 7 Plus from docomo on Saturday. With little time for tests and setting up, I  ventured out to Hakkeijima in Kanagawa the next day to shoot some video with a rig that I wasn’t even sure was going to work.

Because none of the manual camera control apps worked with the dual lens setup yet, I decided to do this first test with just the Camera app. Keep it basic, no color correction just to see what the rig can do. I had tested the setup with my iPhone 6 Plus last week after receiving the Tarion Cinema Mount, but even though it worked well, I had no idea if the dual camera setup would even be possible on it.

Luckily, it did work. I should have documented this process better, but there wasn’t too much to it. I am using an old 1.33x anamorphic that was made for video cameras in the days of 4:3. It’s unbranded, but it’s about the same size as the Sony VCL-W169. These are very rare, and while I have heard of others like mine on the internet, I haven’t seen another for sale in years. However, SLR Magic quietly released a new Anamorphot that has 52mm rear threads like mine that would most likely work with this setup as well if you want to build something similar. This is the only way to get an anamorphic on the iPhone 7 Plus until Moondog Labs releases their adapter later this year.

The major issues I had were with the OIS and the Beholder. Half of it may be attributed to my custom PID settings being for my Sony RX100IV on the Beholder, the other being the OIS would cause the lens to shift where you could see the edges of the anamorphic. Once the Mavis app is updated for the 7 Plus, I’ll give it another go and play around with shutting the OIS off when on a stabilizer.

Switching between the cameras worked really well. All of the automation in the Camera app seems to do well judging the shots, but I am excited to try it out with manual controls. I am especially curious on how the apps out there will deal with the zoom lens, as it has a few quirks I will go into in another post.

Overall I am pretty happy with the results. I tried to color correct a few of the shots and I was very impressed with what the camera can provide out of box. Once I have updated apps and have fine-tuned the setup better, I will give a a go again and really see how far I can push the iPhone 7 Plus cameras.

Hello Yokohama.

Wasn’t planning for this to be my first upload, but all my main projects are taking more time than I planned for various reasons.

I never get tired of city visuals in Japan.

This was mainly practice using the 1080p  120 fps feature on my Sony RX100IV. I wandered into main areas of Yokohama with the camera on my Beholder DS1 and just filmed whatever. It has no post stabilization and no additional time warping or remapping. Just re-interpolate the 120 fps to 24 fps and this is what you get. Aside some issues with color correcting (something I really need to practice more) I’m about 75% happy with how it came out.

Music was thrown together from something else I was working on rather quickly, so it’s not the best mix. No soundcloud until I make something I’m at LEAST 60% happy with.
