UPD: Ha! It was Allbest. He did this for "+Fixed: negative values of EFL for a650". But he did that in incorrect way.

Sorry, It was only defence from overlow

Not more. Thank you for correction!

When you set this parameter in such state you see values that corresponds you previous shoot (or as a consequence of half press). You can renew this values by half press (or if your camera in MF mode than by distance changing).

[-] Miscellaneous values are not displayed at all
with 'Show misc values' [Shoot]
You need half press shutter release button to see this values

Thank you for an answer Allbest.

I know that it should work this way but on my S2 it doesn't

I'm not able to get any value when half-press (or from previous shot) - that's why I'm reporting it as a bug

I can get values only with half-press in <alt> mode.

And? This is a valid syntax. Do not forget that operations (div and mul) are integer, not floating. Without (int) the result will be the same.

i mean (int)((CF_EFL/10000)*get_focal_length(zp)) should be the correct version
making int after multiply is processed

That will not help. Because all operations are integer.
For example:
47297/10000*44400 = ((int)(47297/10000))*44400 = (int)(47297/10000*44400) = 177600 (that means 177.6mm)
because 47297/10000 = 4 (integer)
But
47297*44400/10000 = 209999 (that means 209.9mm)
That's the difference.

well, I made some "progress"...found out that WinXP simply refuses to format an 8GB SDHD card as fat16. Even if the format command says that is what it is doing. Won't do it. So I got out an old SD card and formatted that and put the diskboot.bin from allbest .57 on it and used the bootdisk tool and checked the mbr with a hexeditor and it looks ok...the camera a650 will not boot at all with this card in it in wp mode. It works ok in unlocked, but is dead when the card is locked.vvv thanks

Will someone please put up exactly the code and hardware that they are using and the *exact* procedures and directory-listing that they are using to get this to work with their a650?

thanks

The behaviour of CHDK on your camera is very strange. Please try reload it on your card (before that you need to delete chdk.cfg)
Index of /hdk/autobuild/

I'm just new here.
I didn't download build48 (can't find it).
But I've already download "allbest-a650-100d-49.zip" , extract it.
The file I got is just diskboot.bin.
As I understood(??), there should be another file to put in the root folder of SDcard.
Where can i find "PS.FIR" like that one for a630-640.
Or may it should be "PS.FI2" to use with a650is (I read here -> A650IS - CHDK Wiki)

thanks

If you are trying to get it to work in an A650, you will have to make the SD card bootable.. it is in the CHDK wiki about how to do this. You will need a card reader of course to do this. Once it the card formatted and made bootable, copy the diskboot.bin to the card, then LOCK the card with the little switch. place the card in the camera, turn it on, and CHDK will load:D NO PS.fir file is needed.
