Yves - I've looked at the Google link for those images:

Looks like it still has an eye viewfinder - but looking at the squarer shape of the flash unit, I wonder what on earth they done with the pentaprism! Assuming that Pentax haven't gone the EVF route, I wonder if they've come up with some nifty replacement for the pentaprism

Certainly with an EVF you could fit it in those dimensions...

Whatever the AF540 or AF360 say on the LCD - it's correct
Connecting to a dSLR will automatically sort out the correct angle of view.
Just trust me
Matt

Apart from the legality/illegality issue, the whole thing is stupid - even if you delete and format a card then you have a 99% success rate of recovery (as long as you don't try and write anything else to the card)

To be honest, unless you are actually breaking things , a simple NE555 timer would do the job nicely - you just twiddle the pot until you get a delay that works. It's more predictable triggering a remote flash in a darkened room than trying to trigger the camera

That said, it's still possible to trigger Pentax cameras through their 2.5mm remote control socket.

Polchraine - well, you could always hook everything up to a laptop and write loads of code... or stuff it all in a microcontroller Personally, I take Einstein's (IIRC) motto - "Things should be as simple as possible, but not any simpler"

Hi Darkmunk,
The easiest way is to use an infrared diode, and a light sensitive diode the other end. A 555 timer should do the job for the delay (though really basic!).

I've seen plenty of projects out there for Veroboard... I'll see if I can dig up a web link

What's your electronics experience like?

In Silkypix

Tom,
The K10D really only had a global FF/BF adjustment. Early versions of firmware (think it was 1.10) allowed access to the debug menu via complex key presses. However, after that the keypresses are gone and the way to enable debug was via a USB utility Downgrading is possible - but tricky as the later firmware checks what version you are trying to load and won't allow "downgrading"

There is a little utility available from a Russian site that does the USB trick

It is also possible to take your camera and lenses into Pentax. Apparently they will adjust things for you. (Not sure if there's any fee involved, and no idea on the turnaround time.)

There's a thread on this forum (that I started) that documents some of the possibilities with the K10D.


I would be very surprised if the hardware on the K10D was identical to the K20D If even one connection from the central CPU is different on the K20D (which is very likely) then trying to cram K20D firmware into the K10D is a recipe for disaster. If any of the CPU or supporting devices are different in any way - that too could be catastrophic. I'm not saying that it's impossible... but personally I'd only do it if you can afford to turn a K10D into a dead "brick"

Matt

Just to say that Pentax obfuscated the code in the K20D
The K10D is fairly visible, but the K20D is mashed up to make this exercise harder
Matt

I would say - no EVF, just LCD. This is what most digicam users expect to happen, and allows you to zoom for manual focus (I've even managed manual focus on the K20D live view when zoomed :shock.
I could see that an LCD-only dSLR could be made to work... ok it's not the same as pentaprism, but I could see a market
Matt

From my earlier post:
I'll check out the handling of a 6Mp PEF file on my 1.6GHz Centrino machine later... but 40 seconds does not sound unreasonable.

The PC RAW processing is much more complex when compared to what the camera can produce. The Silkypix engine (which is what the Pentax supplied software is based on) can extract a serious amount of detail, while applying excellent noise reduction - all this takes a LOT of number crunching

Different RAW processors work in different ways - some are faster, some are slower - and have different output qualities. Some handle noise better, etc, etc.

But, as I said, I'll check out the timing of the Pentax software later... and get back to you.
