Yep, a black hole the mass of the moon in the same orbit wouldn't change anything. Although a black hole eclipse sounds fun, I imagine it wouldn't be large enough to be visible from earth with the naked eye.

Would the lensing effect concentrate the solar rays to make a laser like a magnifying glass to an anthill?

It's still only the mass of the moon at the end of the day, so probably not? I don't think density matters here.

It does, since it would be so much smaller it would change the position of the focal point to be much closer.

A black hole with the mass of the moon would be 0.1mm. All that gravity in such a small area would make it strong enough to bend light, but being that small I don't think it would be very noticeable.

You'll have to get the focal point just right as well. There's nothing saying (yet) that it will be the perfect distance.

The moon doesnt, so I don’t think so?

It would barely be large enough to be seen in your hand with the naked eye (before your hand and body brutally contorts and gets sucked into it.)
