These would be using a 3.5mm jackplug, whereas the remote release uses a 2.5mm jackplug.

You need a lens on, and to use a small aperture. Without a lens on you won't see the dust, as it's sitting on a glass layer in front of the sensor. A small aperture gives sharply defined shadows (the spots of dust you see), a wide aperture blurs these shadows to the extent that you usually don't see them at f/4 or so. Having no lens on is the biggest aperture you can get.

Dan

Strangely, that's not right. You lose just 1 stop with a 1.4x teleconverter.

In effect, you multiply the aperture value by the converter power (f/4 with a 1.4x TC becomes f/5.6, or f/8 with the 2x TC, for example).

So it does! Missed that bit.

Nice to see they've got an extra 7 fps out of it too.

Note that the Dixons listing makes no mention of a lens...

That Leica one is around £10,000. Bit pricey to put that in a camera I think.

And can you imagine the complexity of trying to get that to work with 11 focus points? You'd have to adjust the angle of the laser, the angle being dependent on the distance to the subject... Catch 22? Or you could just have one laser per focus point. Oh hang on, that's bumped the cost up a bit! Made things a bit bulky too...

Most of the digital 'tape' measure things you mentioned ("cheap DIY measuring devices") use ultrasound. The ones that use lasers are not cheap, at least the ones I've seen aren't.

I got the impression (and I imagine iceblinker did too) when you said IR beam, that you weren't refering to IR lasers, but just the sort of thing that's used for IR triggers.

I would have been disappointed if you hadn't done.

I'm just content to know that the money I saved building this system myself (as opposed to buying a Mac) was probably enough to buy me my K10D. And a lens or two.

I may have to put up with it crashing when I load a beta version of a fun program, but I can live with that.

Dan

Somehow I knew that someone would say something like that, but I was expecting it to be Don.

My system's usually very stable, can't remember the last time it crashed. The monitor died the other day though. Thank goodness I haven't got an eMac!

Dan

Hmmm, just tried it, but the PC crashes every time you try to process a pic. Heading over to their forum to see what's occuring.

Dan

This was mentioned by someone before, but it was Mac only (and guessing you thought so too, judging by your title), but I've just looked at the site and they've now released a PC version too, so I will have a play with it at some point.
