Are any of these lenses compatible:
Goal: to have a large depth of field … so that feature detection works well, and I can have a high frame rate. The application is for outdoors … so with the sun, there will be lots of light.
I want to track object 0.4 - 0.5 meters away, insects, they are 8mm long.
I am concerned about the back focal length of these lenses … should I be?
Any advice?

They should both work. Note, we sell a tested 25mm lens on our website: Super Telephoto Lens – OpenMV
Ok, thx!
Note: I bought that one and it works, but I would like a deeper depth of field …
The openmv one costs around 6 euro or so, the ones I listed cost around 100 euro.
If you would sell one with high dof, I would prefer to buy that one! But you don´t.
I find this strange, since for robots everything should be in focus.
So I guess they are just more difficult optics and hence expensive.
It doesn’t make sense for us to sell everything. So, we’re probably going to keep the same set of just 4 lenses. There are other places to buy lenses.
