Studiohut 8-in-1 Infrared Remote Controller for CANON WL-DC100, CANON RC-1, PENTAX REMOTE F, PENTAX REMOTE E, NIKON ML-L3, OLYMPUS RM-1, OLYMPUS RM-2 and MINOLTA RC-3

This works just fine w/ K-30. Has a range of approximately 10-15 feet indoors, less outdoors or with bright lighting. Only 2 of the buttons are used for Pentax and the others are for different brands. One button will trigger the shutter release, the other is equivelant to half-way pushing the shutter button as if in auto focus mode, allowing the camera to do the focusing for you. Would have been 5 star review if range had a larger response area, but I suspect that would be the case with all infrared remotes and a radio remote would be necessary for greater distances.

I purchased this on a whim for a family vacation. It shipped quickly and I didn't get a chance to learn how to use it until I was actually on vacation so its very easy to use. For the price, its well worth it.

I was hopeful that for the price and other positive reviews, this would be just what I needed. Unfortunately, the product was dead on arrival.

It works with my Pentax K-r the only thing is I have to do if I am behind the camera I have point it around it to the front other than that it works great

Works for my Pentax K-x. Neat little remote. If it works on Canon's and Nikon's like it does on my Pentax, it would be a great multi-camera remote.

Works great with my Pentax WG-2 -- Enclose booklet shows what button work with various cameras -- very flexibleThanks for fast shipping

This works great for my Pentax K30, very happy and it shipped very quickly, received it several days earlier than expected

Fast delivery and great utility for photography.
