IR remote advice please

I have had a quick look at previous posts via the search facility and not found the answer so I hope this is not a duplication.

Please can some one who has a remote for their K-x or the K-r tell me from what angles and what distance the receiver will "see" the signal, as I gather there is only a forward facing receiver?
[this relates to having the camera on a tripod some distance away from me to take wildlife photos close up rather than using a tele lens.]

Apart from the Pentax IR remote are there other more economical versions [cheaper] available that experience has shown to work?

I tried the television and dvd player remotes but they dont seem to trigger the camera

thanks

Well, tv remotes definitelly won't work
You can find pretty cheap IR remotes on eBay. I ordered one last thursday for $3, but you can find even cheaper ones there. I should receive it this or next week, so I can't tell you about the distance... Just search for "pentax ir remote"; or "k-x ir remote" for the original one (costs about $5).

Actually some people have reported the "off" button on some remotes to work!

I have a cheap one and the distance is fine, I havn't tried to max it out but it's definitely worked from ~3 metres away. The angles depend from which side. If the lens gets in between you and the sensor, the angle is quite restricted, but from the other side it's fairly good.

That's what I've found anyway.

The various IR remotes (including Pentax) have a maximum range of about 4m, and have quite a restricted angle of operation (maybe a 45 deg arc?) in front of the camera.

(No help I know, but other models have a rear facing IR window as well as a forward facing one.)

There are pleany of cheap IR remotes on eBay that work with Pentax dslrs. Maybe if you need more range you could modify one to work with a cable switch? Simple to make and cheap (less than 15 all in).

Hi, you can get a genuine Pentax remote pretty cheap on the market place here or on eBay. I bought mine for $8 a few years back and the price saving isn't enough to consider buying a chinese knockoff.

I can't give you exact angles but anything IR requires line of sight. If you can't see the IR sensor from where you are hiding you won't be able to trigger it. I've managed to use my IR remote with my bodies from around 12 - 15 metres away. The amount of ambient light could be an influence too.

If you want a cheaper alternative you can get a free application to use your PDA or iPhone as a remote. Of course, that's only cheaper if you already have the hardware.

Do the K-x and K-r have a remote socket? I made my own remote release and a 20 metre extension for a couple of $$ back when I had an *istD. You just need a couple 2.5mm stereo plugs and some phone wiring. I've still got the pattern somewhere - pm me if you want it.

That's impossible, today's PDAs don't have IR, nor does the iPhone.
And no, they don't have a remote socket.

Also, I don't think it matters if you buy original remote or "chinese one". They are both made in China and I would say that the "chinese one" has an advantage there because you can usually control even other-branded cameras with it.

I have a K20D and have a Pentax remote and a cheap ebay knockoff, the knockoff has a lot longer range. You'd have to test distance on your camera.

Well, yes they do, the problem is finding one that does transmit the correct code.
My Sony RM-PP505 remotes 2nd room button triggers K100D and K7 up to 30 feet away in daylight.

I just replaced the battery of my Chinese knock off remote, and remembered about this thread so I gave it a quick check . The remote triggered my K-20D at any angle even when the remote did not see the sensor of the camera or completely blocked by a corner of the walls . When I aimed at the side of the camera, the distance was about 4 meters, and when aimed 90 degree to the back sensor of the camera, the distance was about 10 meters ( I had no room to go any farther).

It is possible - you have to purchase an IR 'dongle'.

A quick google throws up this one Infrared Transmitter | DSLR.BOT

Do you think this worked because the IR was being reflected off the walls (sounds like you're testing indoors). Would be interesting to see how an outdoor situation compares.

Yes, I tested indoor and that's what I thought . It's windy today, when it calm down, I'll go out do an outdoor test to see how it does .

Don't worry, I have come to the RESCUE! Anything with an audio jack can set off your camera! It costs 3 and supports anything your imagination can throw at it!

Just in case beginners are not aware, the K20D has two remote receivers, on the front and back of the camera. The K-x only has a receiver on the front, so it probably can't receive off-angle remotes as well. I think the extra IR receiver started with the K10D and is found on all the upper-line cameras since then.
