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.

Q: 4. Does this lens take infrared picture or normal images? (I have seen review of this lens that takes normal images. is there a non infrared version of the lens?)

A: This lens records both infrared and normal wavelengths of light.Most lenses are not corrected for infrared light.Which means if you set the focus on your lens for normal shooting it will be blurred or out of focus for shooting infrared.If you likewise set the focus for infrared and try and shoot the next day in daylight it will be out of focus again.This because infrared light focuses at different points in the lens than all the other wavelengths of light.What THIS lens does is it keeps you from having to refocus everytime you switch from shooting in normal light to nighttime infrared aided light.This is done using a IR coating to make sure the the wavelengths of light focus on the same point in the lens barrel no matter if its IR or not.Hope that helps anserw your question.23

Q: 6. I have a Pentax K-30. I bought this and cannot seem to get it to work if I'm standing behind the camera on a tripod. Am I doing something wrong or is there a better choice?

A: Yes, This remote is an IR trigger, which means it is line of sight. If you are behind the camera,, the camera does not see the signal from the remote.Best way around this is to stand off to one side out of the field of view of the lens you are using.I have K3 and K20d bodies. My copy of this remote works with both.Hope this helps.JJ
