The 1000nm, 39mm Kolari Vision Pro Gen 3 Infrared Lens Filter is fitted with precision machined brass rings, enhanced grip, and a superior lifetime warrantied construction while maintaining a low profile over your lens. This external infrared filter is perfect for adding to a full-spectrum conversion or on top of another infrared conversion to get a different effect. The filter features a hydrophobic AR coating that increases scratch resistance and causes dust, smudges, fingerprints, water, and even permanent marker to slide right off its surface with minimal effort. The brass ring construction features front and rear threading and an aggressive grip knurling for easier filter removal.

Q: 1. Will the Pentax 39892 work with the KS-2 (including zoom)?

A: I have this remote and a K-S2.In auto focus mode - it can work either of 2 ways, the remote will focus with middle button and orange button will also pre-focus and release shutter. That is an in camera setting. OR, you can perform the shutter release only with orange button, and set focus with center button. Handy when you do not want to change a focus overtime you release shutter. Third button down performs a feature that does not seem to apply to this mode cameral. Zoom?? If you mean change in mm shift on zoom lenses (i.e. 18mm-50mm), that feature is a manual adjustment. Power zooms buttons are usually found on fixed lens consumer cameras.

A: No, it's the opposite -- it lets IR light through rather than filtering it off.

Q: 10. Hi! What range could you reasonably expect this to work out to? I have the older remote that came with my Pentax K-5, and it only works out to about 10-15'.

A: Like the other Pentax infrared remotes, performance depends heavily on ambient light conditions. Outdoors in bright sunlight you should not expect more than 15 ft, depending on sun direction. Indoors or int dark conditions, 25-30 feet is reasonable.
