Original Mobius night recording with 4mm ~ F1.2 lens (!)

[Harsh]

I've messaged the seller asking the MP count and whether an IR filter can be installed at their end, let's see.

Seller got back, it's 1MP and the filter can be added.

Thanks for thinking about what I am looking for but there are to many if's about the Ebay lens, one of the main ones being it has a 1/3" format (6.00mm Diameter). The Mobius also has a 1/3 " Sensor (6.00mm diameter), so they would have to align perfectly or there would be vignetting , the chance of that happening is very great. Since tolerances are somewhat loose on M12 type lenses it is best to go up at least one lens format size, that would be 1/2.7" format (6.72mm Diameter). According to the experts you can go up to 1/2" lens format (8mm) without any problems.

I think its sold out.

Yes price seem steep, but its a lens jungle out there, and i figured if peau was selling it then it cant be all bad.

Back on sale, but I'm sure the price has gone up

That's the same price it was selling for previously....$40.00 USD.

Oh, you stated where doe's it end?, When you go out to work and see that you need a new truck mount for the cameras you are driving !

OK, I promised you some pictures on how I mount the camera's in the truck. Many of you know I drive another truck every day, so I can't use a permanent solution, it needs to travel with me in my bag, and needs to be mounted and dismounted quickly, but securely.

The mounts start out like this:



Yes, generic steel door hanger, bought from .... don't remember, some chinese shop, virtually for grabs....

Then take a hammer and an anvil of some sort, reshape to this:



I need this shape due to the trucks dashboard shape, they mount right in front of me where I sit, behind the steering wheel (picture further down), where there is a ledge I can stick these mounts on.

Under the round black rubber there is a round, flat magnet which sits in foam rubber which I cut out from protective, self adhesive pads that go under your chair-legs.

Rubber for stability, and to prevent the camera from inadvertently turning away from the windscreen.... I can't fiddle around when driving.

Stick a metal plate on the camera's bottoms



and then it looks like this with camera on (single use)


If I want to do some comparison, I use 2 of these mounts and a little bridge, made from the same door hangers, stick some magnets on, and cover with foam and rubber again (I used a damaged innertube for this one....)





Contraption with camera's on:



As you probably see, I use some foam or rubber pads to protect the dash from scratches.

Hope you like it, and maybe can put you in a direction to solve something similar.

Here's a picture, let's say I made it ONLY to show you the mounts behind the steering wheel.....



Better view here:





Piece.

Just got me the other F1.2 lens, sticked it into the JooVuu X.... oh goodie goodie goodie, can't wait to test it out tomorrow....



ATTENTION: The lens is a little bit too easy fit to my taste, and fastening may need some glue. I however took the fastening ring from the Runcam Split lens, this enables fixing the lens without glue, maybe these rings can be obtained from some source, I don't know, just took it from Runcam's lens. Looks something like this:



Oh, and since I didn't really get a satisfactory answer from JooVuu's "customer care", "support" or whatever that is called.... I took a spare Mobius 820mAh / 3.7V battery, soldered the Joovuu cable / connector to the battery, and hey presto, the JooVuu has juice again.... so cool.... repairing the Joovuu X with Mobius spare parts.... HAHAHAHAHA

Anyway, it works.

AND IMPORTANT: the 820mAh fits like a GLOVE into the Joovuu's housing....!

Maybe of help for anyone....

Piece.

Just search for, "M12 lens lock rings". (Jam Nut) They are available and not too hard to find.

The Mobius looks like a sci-fi laser weapon sitting there Good job on the mounts- simple and effective

I just received notification that my new Starlight lenses are arriving today

 

[Lola]

Alright!! I hadn't looked yet, but there you go!

You can also get/find metal ones (lock rings) if you don't care for plastic.

Ooooohw snap....

Got my second F1. 2, here's some examples in the JooVuu X. Is it better than with the original lens? I think it is, but I only have one JooVuu X so can't yet compare.

1st two are 60fps 1080p, the other two are 1080p/30, HDR.

 

[Dashmellow]

First quick impression is that this lens does much more for the Mobius than it does for the JooVuu. Somehow that doesn't surprise me.

Always enjoy your musical choices @dirkzelf!

Now that's what I call a "long" lens. I'd love to see a photo it produced.

I encountered a few teething problems in my aim to run a 4mm F1.2 and 6mm F1.2 side-by-side in my 2No Mobius 1 cameras. I started out with an original A-lens camera with the early production case (with a round LED), and a much newer lens D camera. I successfully modified the lens hole on the original case to accept the 6mm lens barrel. Managed to get it focused easily and locked off with the set screw. So far so good. First test run tomorrow

Then I tried to swap the D lens for the 4mm F1.2. It was then I found that the D lens was glued in to the lens holder, and there is no set screw on this new Mobius 1 It's also a plastic lens body rather than glass, so I had to be extra careful cutting away the glue without stripping the lens thread. I did get the glue off, and managed to remove the lens. Then I noticed that the D lens holder has a much shallower threaded depth than the A lens, approx 6mm vs 12mm. Unfortunately that was not enough to hold the lens thread secure once it was in focus - it almost fell out just by tapping the camera. So that lens holder is only good for lenses with a short back focal length

Thankfully I have another A2 lens Mobius on order, which looks like it has a good length lens holder so I can swap out the A2 for the 4mm F1.2.

You can buy a deeper aftermarket M12 threaded lens holder and simply swap it for the shallower original.

Here's an example of one that is 16.5mm tall with 18mm screw hole spacing.

This business of Mobius doing away with the adjustable focus lenses is a huge step backwards!

Thanks. I have a spare C2 lens module & lens that I salvaged from a damaged mobius. I can try removing its lens holder to see if that works.
