Hi,
I just got my OpenMV Can H7 Plus. I am having trouble focusing the lens. I do not seem to have the proper tool for the set screw. What tool is required?

Just a small screwdriver, there’s a small screw the keeps the lens in place need to loosen that and adjust the lens, then tighten it again.
I do not have a screwdriver that small, so this is going to be a problem for me. OpenMV should include the proper screwdriver.

This is not something that users need to do normally, as far as I know the lenses are pre-focused in the factory @kwagyeman , I could be wrong or they must have missed some.
In the tutorial, it says we have to focus the lens. The lens on mine is definitely not focused. I still can not get the screw untightened so I can focus it. None of my screwdrivers are working.

Hi, we don’t sell the camera with the screw anymore. We switched to a new lens ring around the M12 thread because users have this issue. You must have an older production run unit. We started doing this new build about las year.
I just got my OpenMV Cam H7 Plus from SparkFun. How can this be from an older build? So, how do I focus the lens in my camera?

Without the lens ring you have to unscrew the set screw, then focus the lens, then tighten the set screw. Any jewelers screw drivers can be used to release the set screw.
As for it being an older build. We didn’t mark the H7 Plus with a a set screw versus a lens ring to be a different product. We just start shipping a different one after a while doing production runs. So, inventory may be mixed.
I do not have any jeweler’s screwdrivers. Nothing I have here will work. I just want to be able to start using my camera.
You really should NOT have mixed the inventory of older versus newer units. Use older inventory first.

I just got some very small screwdrivers, but I still can not get the set screw out so I can focus my camera. I do not know what the difference between the small screwdrivers I have and jewelers’ screwdrivers are.
I am getting very frustrated and just want to use my camera. I am not having a good time with this.

Would you like a replacement camera? I can send you one. I can ask the warehouse to send you one with the new lens screw ring that is tooless.
Hi,
Yes, I very much would like that. I have wanted one of these for a very long time.
