It makes sense to evaluate it in night mode, but some cameras claim good low light performance in color (day mode) as well. Will you test these lenses in color as well?

Thanks Ethan. Could you clarify one thing? You said:
But this seems at odds with the information in the f-stop tutorial:
Is there a subtle distinction I'm missing?

Would be interesting to see a depth of field comparison or calculation of the lenses as well.

John, does the fact that the Hik lens and the Computar lens have different formats have to be considered? The Computar is listed as a 1/2.7" and the Hik is listed as a larger 1 1/8" format.
This means the diameter of the image circle formed by the lenses is different. For the Computar looks to be around 6.6mm, whereas the Hik should be around 9mm. The 5004's sensor is a 1/3" or 6mm diagonal, so although using a lens with a 1 1/8" format lens is possible, it wastes much more of the light passed by the lens, than the 1/2.7" format:
I didn't look up the other sensor sizes, I just wanted to throw this out for discussion and see if it makes any sense first.
