3.4mm No Distortion Lens for GoPro 7 Hero Black

I think using GoPros for 3D is pretty cool. 

My biggest issue is that I don't want the ultra wide fisheye look.  

Yes, you can defish the video in editing or record in LINEAR mode and save a lot of money but I was looking at other options.

One option is to swap out the lenses on the GoPro. Earlier GoPros use m12 lenses?

(Newer GoPros make this impossible without a spendy conversion--which means you might as well have bought a proper camera).

The GoPro 7 Hero Black lenses unscrew right off so I searched the web and found that the 8K production Store on AliExpress has a 3.4mm no distortion lens for GoPro 7 Hero Black.

The biggest issue after installation is to set focus. (You only have to do this once).


You have to connect the GoPro via HDMI to a monitor and slow focus the lens. Once dialed in, that's it.
Here's a link to the item.  (Not an affliate link. I spent my own money on the lenses)

Another option was to buy an action camera with a no distortion 90 degree lens.

The Firefly 8se with the 90 degree lens seems like it would do the trick.

Hmmmmm... this is very interesting! Pentax WG-1000


 


This seems like a very good candidate for a 3D video rig. With one camera flipped, and the metal strap ring removed.. it seems appears to give you a lens separation of 72mm.

It only does 1080p video.. but it's an affordable camera.  Not bad.  I would like 4K though as it wouldn't improve my Nikon P330 setup currently.

If set up side by side.. it appears the lens separation is 105mm.

One of my hobbies is to imagine if a certain camera might work for 3D video....

 I usually look at cameras online and check their dimensions.

Here is one: Canon EOS R100... an affordable mirrorless.  I bring an image of the camera into Photoshop and try to do some measuring after mocking up a configuration. 

 4k recording is cropped, so that might be good for hyper stereo video.



The camera is supposed to be around 4.6 inches wide.
Distance between both lenses would still be 9.5 inches or so. Hyper!

Straight side by side layout is around 115mm between lenses.  I might as well stick with my Panasonic G7s.  I think the GoPro with modified lens is still better.


I've also been looking at a Mokose 4K camera online.

Gene Shalit Critic's Corner Set in the 80's

I remember going to the NBC Tour which included the Today Show in the late 80's. 

One hilarious thing I learned was that Gene Shalit's Critics Corner "set" was basically a small lemonade stand sized thing. 

Shalit sat on a stool!

Through the magic of television, it looked like he was in really amazing office. 

So clever!

Spam Notification: "Finish Cellular Setup - An eSim from Cricket is ready to be set up on this iPhone"

 So I got this notification last night:

"Finish Cellular Setup - An eSim from Cricket is ready to be set up on this iPhone" 




I'm saying what? What the hell is this.

I go into Settings:  "Set Up Cellular"





Then I hit cancel.







I've gotten the notice three times so far. Bizarre.

Great app: i3D Movie Maker for iOS and Macs with Apple Silicon

 https://apps.apple.com/us/app/i3dmoviemaker/id1560663523

i3DMovieMaker

This iOS app will allow alignment and conversions of Side by Side videos into Anaglyph versions

It's worth the money and a lot easier to use.  The best part is if you have a Mac with Apple Silicon the App works also.

How to use a pair of Panasonic G7's for 3D video? This might be a manageable solution...(NOPE)

A pair of Panasonic G7's is just too big to set up for normal 3D, the stereo base between two cameras would be too wide.

Even mounted vertically,  the stereo base is too wide. ( I was going to crop the 4K image to (2160x2160)



The possible solution is a right angle scope.  I could use one, or pair and have the two cameras set up in a "opposing" configuration for 3D video.  Stay tuned!

I got the things to play with and nope, it will not work. 
The length (height of each unit makes it impossible to get the lenses close together in an opposing mirror setup. One also has to zoom in quite a bit.  This is a fail and waste of money.
