Does the Pentax DA 15mm f/4 Limited have image stabilization?
No. Pentax bodies stabilize the sensor, so shake reduction depends on the camera.

The filter thread is 49mm, so standard 49mm polarizers and ND filters screw straight onto the front.
How close can it focus?
Minimum focus is 0.18 m, with a maximum magnification of 0.15x. That is close enough to place a foreground subject against a wide background.
