They are both fine and you can make a wrong choice really.
AF and macro don't go well together, most of the time I put the lens near the focus I want and use my body to get the focus right, there is really no simple way of doing it I'm afraid.

The DFA has quick-shift and I like that and the lens is light.

The focus limiter on the Tamron makes it better for general use but like said AF is no real option with macro.

Most of the time Pentax is a better buy simply because of the resell value but since it's a Samsung badge things are a bit different.

Just try them out and get the one that feels best, that's the only real advice I can give you about the purchase.

Then you've everything settled then, good luck

To be honest you might be better of getting an ring flash, though.

I believe it's part of quicktime, there are multiple software that can do it.

Pete, nice videos. Would love to see more.
I might make one a Saturday with the KX.

Simply fitting a collapsed monopod under the camera helps to stabilize it since the point of gravity is shifted further down, I sometimes used it for photography.

Depends on the focal length that they used and camera.
