I recently purchased an intervalometer to let me shoot time-lapse pictures with my K100D Super. Here's what it looks like:



I got it from Amazon.com through the EShopic retailler and I've been very happy with it. EShopic shipped from Canada to my Canadian address within a week without any extra charges over and above the standard shipping cost. I just posted a review on Amazon and I thought I'd republish it here for any of you who are looking for something like this:

This remote timed shutter release provides five settings:
  • the DELAY before the first shutter release
  • the exposure LENGTH (how long the shutter "button" is pressed)
  • the INTERVAL between shutter openings
  • the NUMBER of pictures to take
The DELAY, and LENGTH can be set from 0 seconds to 99 hours 59 minutes and 59 seconds. Setting the LENGTH to zero is equivalent to a momentary press of the shutter button, and setting it to a longer value is useful at night for taking long exposures with the camera on a "bulb" setting.

The INTERVAL can be set from 1 second to 99 hours 59 minutes and 59 seconds, as long is it's at least as long as the LENGTH. The INTERVAL is the time from one shutter opening to the next, so for example an interval of 10 seconds means that a new picture is started every 10 seconds, even if the LENGTH is, say, 5 seconds.

The timer sends a "shutter button half-press" signal to the camera for about 2 seconds prior to the actual release of the shutter to trigger the camera's autofocus (or less than 2 seconds if the INTERVAL is less than 2 seconds). There's no way to disable this, although it's easy enough to turn off AF on the camera itself if you don't want to use it.

The NUMBER can be set from 1 to 399 or "unlimited"

You can also enable or disable an audible tone that sounds with each exposure.

The built-in LCD display shows the various settings and includes a backlight for use at night. The backlight is activated with a button and stays for a few seconds then shuts itself off. There is also a small LED light that blinks when each exposure is taken.

Controls are simple - a "SET" button with a four-way rocker to set the various times, a "start/stop" button to actually start the timer up to take pictures or to stop it, a button to activate the LCD backlight and (if held down) lock the settings, and "shutter" button which lets you use the device as a simple remote shutter release. The "shutter" button has a slide that locks it into the "down" position which lets you take manual "bulb" exposures without having to hold the button down manually.

The unit takes two AAA batteries and it claims that the batteries will last for 2 months with the unit actively triggering pictures every few seconds. I haven't had an opportunity to test that.

I've used this a few times now and I like it quite a lot. It does exactly what it's supposed to do without any fuss. I was a bit confused by the controls at first because I thought it had different "modes" of operation: Delay, Interval, etc. - then I realized that it really only has one mode that uses all of the different settings.

My only gripe with the unit is that there's no power switch on it - the LCD is always on and this leads me to wonder if it's going to run down the batteries while in storage. To be safe, you could remove the batteries when you're not using it, but that's a bit of a bother.
 
Hi

I have been wondering about getting one of these gadgets to play with.
There doesn't seem to be a downside.

Thanks,

Rod

Hi Sean,

The Intervalometer that I bought has everything you wrote about, including 1-399 or infinite shots, and mine has an On/Off switch.

Mine also works great.

If you "lock" the remote, only a tiny bit will be displayed. Not ideal admittedly, but if you think how long a digital wrist watch runs on a smaller battery, it should not really be an issue.

I'm a little reluctant to supply a link because of the forum's "no commercial activities" policy, but if you do a search on Amazon.ca or Amazon.com) for "pentax timer" you'll find plenty of links that show exactly the same remote. A search for "pentax intervalometer" isn't nearly as useful.

Too late for me, but on behalf of the next person this helps out - thanks!

What I did was to slip a tag of paper into the battery compartment to prevent one of the batteries from completing the circuit. When I want to use the timer I can remove the slip of paper from the contact but leave it in the battery compartment. That way I know there's no battery drain and I also don't have to worry about mixing up the batteries with others or forgetting to take them with me.

I completely understand, but...

does this apply to Amazon, too?

Genuine question, I don't know:

But as dpreview is owned by Amazon, I thought they would be okay with such a link. Maybe not, though?!

Thanks, Sean - I can understand your reluctance. My interpretation of the policy is not to engage in commercial activities that benefit you directly through a service or product. Referring to a commercial site or vendor which you are not benefitting from seems to be fair game in my mind - we have certainly had plenty of it in the forum (not that it makes it right per se, but I believe most interpret the policy the way I do) I will take your suggestion for search criteria.

If you don't mind a little bit of work you can make one of these.
The only problem is that you might loose it in your bag!

Yes, there are several similar projects on the web. Lower functionality than the full-size ones. And cost-wise only interesting for people who enjoy doing this - otherwise it will take more time than worth it, IMO. SMD soldering isn't a skill most humans are born with ;)

For every hour you curse at your soldering iron you could be out and taking photos.
Just my spoilsport opinion.

I strongly considered designing and building my own, as I have a fair bit of experience designing and building my own electronic projects. The circuitry required is pretty simple.

But reason got the better of me and I realized that for $30 bucks I'd end up with a more finished, professional product that probably wouldn't be any more expensive once I factored the cost of all the materials.

I have no idea and to be honest I'm too lazy to research it - so I'm playing it safe by not posting a link.
Easy enough to just look on Ebay, they are available in a number of slightly different versions.

It looks like materials would be under $8 but the pic programmer would be at least $50 and you need a fine tipped soldering iron and a steady hand.

So it looks like buying one of the other devices mentioned here would be best if you don't already have the equipment.

I actually have a PIC programmer that I built for some other projects, but it's for a PIC16-series microcontroller in a 40-pin DIP package and I'd have to research if it's compatible or not.

That is a really cool design, though, and that 6-pin microcontroller looks very interesting.
