Hi,
Have anyone tried a different camera lens on the Blue Robotic camera?
I want to see if I can optimize the quality of the video, maybe a wide angle lense and IR filter.
I have tested various types of lenses, with an aperture from 100 to 180 degrees, I have not been able to improve the quality much, but my aim is to have the same vision of my gopro hero7 black that I have on board my bluerov2. With the 120 degree lens it is similar. I did this to see exactly what the gopro sees, with which I record in 4k. The only drawback is that the image with these wide-angle lenses is distorted on the sides. These days I bought a compatible camera on aliexpress but with a sony imx290 sensor and a 120 degree lens, and the image is almost perfect, even if the image quality has not improved much. The central area is in focus and slightly out of focus on the sides. However, having a 120 degree view, I can orient myself better during my explorations.

Some notes from my previous discussion with Marco:
Seeing Better (Quality/Resolution)
EDIT: Thereâs some extra context provided in the âcamerasâ section of this post
This is only relevant if youâre planning to use the camera quite a bit outside the water. Water absorbs IR light practically instantly, so adding an IR filter just slightly reduces the light that can enter through other wavelengths, without the normal in-air benefit of slightly better colour quality/correctness.
If youâre after colour accuracy/visibility enhancement underwater then youâll need to look into cameras or processing that are specifically made for that. As a few potential avenues that have been mentioned on the forum, thereâs
| Forum Link | Camera? | AI-capable? | Algorithm included? | Sold By | Notes |

| Premiere Pro editor color correction | No | No | No | Adobe | post-processing only |
Seeing More (Angles/Directions)
Note that those are all focused on improving the quality of the image, not the viewing angle. If you want/need to see more around you youâll need to look into
- wider angle lenses (as you mentioned),
- greater manoeuvrability (e.g. via a multi-axis gimbal), or
- adding one or more extra cameras (see here for Companion and general information - BlueOS supports multiple camera streams by default, so it just requires receiving them at the topside).

Hi there, Iâm wondering if anyone has new info about trying new and improved USB cameras instead of the original BlueROV2 camera?
Hello,
I am selling a nice camera on the bay that I have used in a modified BlueRov2:
SONY FCB-EV7500 30x Optical Zoom HD Camera Module & TL-7051 Digital HD Interface
The camera delivers a great picture and has an incredible 30x zoom.
Hi,
Anyone found a full HD Camera with 60fps that works with the bluerov? Doing lots of net inspections and if we move to fast the image gets blurry.
