K-01 v1.04 Firmware Changes

Okie, so this is what I've spotted so far. And Yes, Video is my priority.

First up, the biggy. YES!!! The ISO no longer changes when a K-M lens or a K-A lens in Manual Iris positions is used.
This means that anyone wanting to use M42 mount lenses, or non K lenses with adapters, will be able to do so with confidence that the ISO (or Gain in video terms) will not change.
For comparison, I put the ISO in Auto, and it then alters, but it no longer does with a fixed ISO setting.

For me personally, this lets me be a lot more creative when shooting in varied lighting.

Unfortunately, no kick up in the data rate - it's still reported as around 20mBit/sec in QTPlayer's Movie Inspector.
And the Audio is still 32kHz sample rate.

Will edit post as I see what else is different, feel free to add Photo-Centric comments for those whose focus is stills (Pun intended)

good!
I have tested quickly the DA 21 limited and seems autofocus better, definetely faster, I always suspected it didn't autofocus properly. Not a problem before with DA 70 or 40 XS.

Yup, did that, installed with no probs.

One observation tho' - In the instructions it said the LCD would display as per the following.

QuoteQuote:

9. Card access lamp will be blinked and display will be changed from
[NOW LOADING] to [COMPLETE].
*Do not turn OFF the camera while updating.
I never saw the 'Complete' come up on the screen, the camera just auto-shut down exactly the same as when I installed v1.03

One fresh observation - the 'preview' function, to display what a photo will look like before shooting - the one where the Iris stops down to the users setting,.. Where before it suffered from ISO shift (just like video with a K-M lens), now the preview holds correctly.

I am so very tempted to go by a second K-01... I know where there is a black one still in stock.
If only the Data rate had been bumped up, and the sample rate shifted up to 44.1 or 48kHz,...

<sigh> Pentax: it's so much better, and it could be AMAZING with just a bit more work!

I did see the 'complete' come up on my screen, briefly. It's interesting that it didn't appear on your screen.
You are right, the k01 has just gotten more awesome. I don't know of any other camera around $300 that gives you true full manual mode while recording.
Pentax should really do something about the sample rate, though. I would even pay for an update to increase the rate up to 44.1KHz...

I find the AF is slightly faster compared to the previous firmware.
Tested on FA* 24mm and FA 43mm.

44.1 would be nice, 48kHz would be better - more common now for add-on recording devices like those from Tascam and the Zoom series.

And no joy on the HDMI output being available during recording

The stop-down-preview works properly in Video now, but when I swing it around to 'M', it still does the same thing, trigger the the iris to move, which is compensated for by the ISO in the live view.

Itís either a placebo effect or the focusing on the K-01 has improved quite significantly with the latest firmware. I havenít done any extensive testing Ė yet, but at least with the DA 35mm f2.4 indoor, in difficult lighting situation the camera seem to focus quicker, less hunting and improved accuracy.

Just installed, thanks for posting! The screen flashed 'COMPLETE' when the new firmware was loaded. AF algorithm has definitely changed. Seems more like the Q now.

Is this a good thing? My K-01 is en route to my door. Got it for size, IQ, and focus peaking advantages over my K-7 (which I will most definitely be keeping!). So I'm interested in this apparent AF improvement, even though it was about the last thing on my list for this cam.

Most certainly a good thing especially for AF shooters like me. K-01 produces excellent IQ but the AF can get frustrating at times and takes some getting used to. From my limited tests using a DA 35mm f2.4, AF with the new firmware seem to be faster and have better accuracy on locking at the intended subject. Of course, if you will be using MF most of the time then the AF improvement might not be relevant for your intended purpose.

Yes, the Q is really fast and accurate.
