lens

Hi, everyone-- I've been a happy owner of a Mobius 1 bought years ago on this forum's enthusiasm about it. Over time, probably due to the hot desert climate, the focus has gone further and further out such that it's blurry all the time, whether cooled down or heated up. I bought a 0.9mm hex...

I replaced the lens with a narrow-angle one (25mm 1/2" 5MP from ebay) and can’t turn off the lens shading correction which is needed at original lens. Therefore, the picture is brighter at the corners. I hope that "Adjust lens distortion" settings will help, but there is no such option in HV...

Hi! What is the meaning of A129-G, VIOFO A129-DG, VIOFO A129-D? And how come on the website states: Input DC5.0V/3.1A via mini USB https://www.viofo.com/home/81-62-a129-front-5ghz-wi-fi-full-hd-dash-camera.html#/25-gps_module-included Same as this...

Hi folks, the A119S V2 I bought just last week from a popular eBay shop was delivered, and it has the old F1.6 non-coated lens. I've attached a photo of it. I am surprised and upset as the improved F1.8 coated lens has been out for more than 8 months (link: A119S Lens Comparison old F1.6 vs...

How do you figure out a lens' aperture without knowing the specifications?

Am I missing something? The m12 mount seems too tight to change lens. I can only screw it in a bit... I've used the allen key to remove the locking screw already.

For quite some time I'd been noticing an interesting M12 zoom lens on Banggood selling at a very attractive price and finally went ahead and ordered one. This is a fast ƒ1.4 - 2.8mm to 12mm Varifocal manual zoom designed for CCTV cameras that will accommodate a 1/3 inch sensor and captures an...

Hey guys, I have recently bought T5. Since I have it especially for exterior filming, unfortunatelly I found out that my lenses are focused at distance around 40-50 cm. Actually this distance is unusable even in interiors... Has anyone tried to disassemble the camera and adjust the lences for...

Hello, I am looking for a possibility (presets, profiles) to correct the lens distortion of YI 4K in Adobe Premiere Pro. Best regards.

Decided to share my experience with several A119S dashcams all slightly blurry on the left side. If anyone has this type of issue return and exchange the dashcam. I wanted to tinker and working with approval from the vendor and VIOFO to repair my 3rd A119S. Far too much effort and detail for a...

So I am a bit of a derp here, but I was trying to adjust the focus on my DR650S-2CH's forward (main) camera. I took of the surrounding clip part, then unscrewed the main screw bit. To my dismay, even while doing it carefully, I did a silly thing and just kept unscrewing. Now I've got the...

I have seen videos and it looks like it helps a lo to have filter. Can someone confirm if it helps and know if there is someone who sells it for the DAB205

Obviously the fish-eye comes from the lens placed in front of the sensor but I havre seen elsewhere footage that is not so wide and only mentions software or firmware hacks. So other than buying another lens, is there perhaps any way to get the software to choose a central area of the footage...

Hello @all I recived my xiaomi z23L and I'm not sure if my cam is ok. FW: 1.2.13 Because I have graining in my recordings and pictures, also my pictures has a gray dust and the left corner is more sharper than the middle and right side I am opening this thread. I hope we can focus our doubts...

Hi everyone New to the forums. Basically I had a bad crash with my Yi onboard my drone. The camera still works but I now have a smashed lens and badly cracked faceplate. Also lost the plastic power button. I know I can get a spare lens at gearbest but not the other parts. So I was wondering if...

Can C2 lense be installed in any mobius version? It seems that it gives better night performance. Also is the performance difference worth the upgrade?

Hi guys ! I loaned camera with original lens(NO IR FILTER) from my friend and make comparison footage with my xiaomi with lens from gearbest(IR FILTER). I think i focus my camera better then his so check it out and tell me what u think. I like his blue sky maybe little more then my but there is...

I'm considering a camera with the following specs per the manufacturer: Image Sensor: 16.0MP full HD CMOS, manufacturer not specified Chipset: Ambarella A7LS75 Video resolution: Full HD 1080P at 60fps/30fps, 720P at 120fps/60fps/30fps, 848 x 480 at 240fps/120fps/60fps/30fps Image Resolution...

Firstly, hello all. I received my first Mobius C2 camera today in the hope of recording my bike(cycle) rides. Upon first testing the focus was set far too close, in completely macro mode.. so I opened it up, unscrewed the grub screw that holds the focus lens in place, got it perfectly in...
