I like the idea to have a HD PENTAX-DA AF REAR CONVERTER 0.66X AW to use all FA/DFA lenses on APS-C Bodies in the same way as on the new KB-Body :)

(Think, K-S2 looks bigger than K-S1 but isn't really bigger...)

There still exist a page about the "Ricoh RDC-7" here: https://www.ricoh.com/r_dc/past/rdc/7/

And there still exist some example shots: https://www.ricoh.com/r_dc/past/rdc/7/sample.html

Are there any plans to implement a software focus limited, so that e.g. the DFA 100 WR will be more useable?

Yes and no...

The EyeFi Card worked in K-30, too. Yes.

But the K-50 has some additional for it. e.g. detects the card and can turn WIFI on/off...
Don't know if this "communication" can be done with the K-30 hardware. Maybe the SD-Card slot must have some additionals?

But maybe the WIFI on/off works just like to store a file on SD-Card?

Just compare:

K-30:
-> Pentax K-30: Camera WiFi Cards and Compatibility | Eye-Fi Support

K-50:
-> Pentax K-50: Camera WiFi Cards and Compatibility | Eye-Fi Support

It maybe work. But don't know...

As i sayed: The question is: Is the hardware around the SD-Card changed, to support the EyeFiCard?!?

I used Pentax Firmware Decrypter and created decrypted files from k30v106 and k50v102 and compare them.

Seems that they are very similar. But there are some "offset" changes, so a binary compare doesn't have much significance.

I used "strings" on both files and create a "patch" file: [Diff] --- /media/servershare/Hacking/Pentax/Firmwares/k30v106_strings.txt +++ /media/ - Pastebin.com

Many string diffs aren't relevant.

It seems to me, that the main difference are the "EyeFiCard" support.
The question is, are they hardware changes needed, to support the EyeFiCard or is this just firmware changes?!?
So, is it possible to support the EyeFiCard on K-30 by just flash the K-50 firmware?

"EyeFiCard" related string changes are e.g.:





Code:

Gratulation!


I think the best idea is to compare the existing firmware files. If the hardware is the same, the files can't be to differed, isn't it?

So just decompile last K-30 and K-50 firmwares and do a diff...

Just add a costumer settings, that say:
1. use pre-shot lightmetering (Current solution with the diaphragm closed and green button)
2. use working lightmetering (Doens't pressure the aperture lever, darker view, but no green button needed)

(Sorry don't know the english words for "Offenblendenmessung" and "Arbeitsblendenmessung")

A diaphragm simulator would be nice... But a simple firmware change would also help to use M-Lenses and thats with all existing DLSRs, expecially with the K-01...

@Shodan: Can you edit the first post and insert links to:
and maybe to your PDF: https://www.dropbox.com/s/ogez7sb4b0cw92g/hacking_pentax_k30.pdf ?

One question: Does anybody compare the K-30 with K-50 (and/or K-500)... Are the hardware 100% the same?!?
