I did not make up the canon guy...you've called me a lier again....and i don't appreciate it...

No I didn't. I said it was one of several possible explanations, and explicitly said I didn't think it was the most likely.

i don't believe i was "insisting" anything...i just said that it seems to be possible...

... after the people who actually made the hack told you it was not.

Note that no one is saying it is technically impossible to do, we're just telling you this hack doesn't work that way, and anyone who said otherwise is wrong. Writing to on-board flash isn't hard, but eventually someone would brick their camera and get all pissed about it, regardless of how many warnings and disclaimers were put up. Plus developers would be at a high risk of bricking their cameras, which would get expensive real fast. Flash cards are cheap, if you can afford multiple DSLR systems, having enough to dedicate a few to each camera should not be a major burden.

fair enough....
misunderstanding from the "hack" writer's intent on my part...
and the tech (remember there is always the " this call may be" ...thingie) so the tech was honest but as you stated, could not divulge the proprietary canon info about the "hows, whens, or whys")...
i understand that....
i'm also a little ocd about my toys...it's not about being able to afford multiple systems, it is being able to modify something so it works the way you would like it to...
I used to build dragsters and build extremely modified engines...
the thrill was about taking a small block v-8 rated at 150 hp and make it crank out 500 hp...
hopefully, you'll undrestand the analogy....

cheers,

tim

and that's all there is to it...making an xti behave like a 40D....

lglass, just FYI if your 40D doesn't have the bootflag on, having the autoexec.bin in the CF isn't going to do anything else than some few kilobytes lying on the CF.

You can mix your card without problem, except if you have also modded your 40D (And I dunno if it is possible, I am lazy to check the wiki)

If you just want to stop using the added spot metering and 3200 iso, just delete autoexec.bin from your CF.
I saw somewhere a modified testfir who reverse the state of the boot flag, but I don't see why it can be needed.
Just format your CF will bring you to a point where near nothing except the boot flag is still modified.

Can u find the topic about the"modified testfir ", tks
I want to go back to original just for boot flag on is more card-reading and power-consume.

I'm ignorant and won't pretend to be otherwise...
having said that, you're saying as long as the testfir.fir file is not intentionally (or otherwise) installed to my 40D, i can safely interchange cards between all my cameras...just make sure i have the .bin file on a card and my xti will do as as the "hack" is intended...

I really like the "hack" it seems to improve the camera across the board....the metering is incredible and it seems to focus faster without as much hunting...of course, it may be like driving a clean car...they always seem to run better...

Here is my AUTOEXEC file: http://www.filefactory.com/file/a12g99e/n/AUTOISO.zip
It's simple auto iso logics. What i can't understand, if it freezes on same iso, i can't reset program by pulling batteries out. Have to load another autoexec from http://chdk.wikia.com/wiki/400D to reset it. Does it use flash memory to store variables?

Sergei

Another AUTOEXEC.BIN and sources:
http://www.filefactory.com/file/a13hg3d/n/autoexec_low_iso100_autoiso_20091222.rar
It's AUTOEXEC.BIN.20090913 from http://code.google.com/p/400d/downloads/list with added autoiso in Av and P modes. To activate autoiso turn "shoot without CF" ON (after activation, sometimes you have to press print button once), and if you need to change other additional functions turn it off. Auto Compensation doesn't work right when switching from 80 and lower to 200 and higher, so iso 80 and lower is disabled.

hey, the AUTO ISO is awesome!!!

Can it work together with other function? Because once i set Auto ISO, i can't set the Focus Framing & Spot Metering.

Hello Sergei,

First of all thanks for this work, it's look great.

I'm a diver and I use my 400D underwater, the spot measurement can be very helpfull but ...

I can't have any access to the print button when I am underwater. My housing hasn't got the print button available...

Is it possible to change this and to use another button, like the jump button (or trash button when not viewing any photo) ?

Regards

Fred from france

It will work together with other functions. You need to set other functions before switching to autoiso. Then if you need to change focus framing, spot metering, etc. again: turn autoiso off, change it, turn autoiso on. I know, it is too many buttons to press. I can't figure out how to put autoiso on the same loop with other functions.

Fred, i don't think i will be able to help you with the print button.

Sorry for my bad English.
I have looked the program listing responsible for function AutoISO. (main.c) From it I have understood that for ISO100 and ISO200 the shutter speed varies from 1/100 to 1/200. For ISO400 from 1/30 to 1/125. For ISO800 from 1/15 to 1/40.

Whether it is possible to make so, what on ISO400 and on ISO800 the shutter speed varied from 1/100 to 1/200?

Zibri

can anyone implement all function in a custo menu like with the 350d modded firmware?

Sergei

Shuter speed set points was set to 100-200 in autoiso:

what do you mean?

Sergei. Many thanks. The program works correctly.

A friend of mine gave me the hint for the firmware hack v1.1.1 and we both enjoy the new features now, especially the additionnal ISO values -- THANK YOU to the responsible guys for the work you performed! 😎
Is there any chance to enlarge the Auto Exposere Bracketing (AEB) function to +/-3EV...? That would be another tremendous benefit -- the camera given +/-2EV are so annoying while creating DRI und HDR pictures... :😀

I have a slight problem, I use 2 CF cards now. and I both formatted them when I bought the new one, so I lost functionality of the hack. Now, when I made the Cf bootable and put in the new autoexec.bin, the camera does not work with that CF, while it works with the newly formatted one. What do I do to put back the hack?

mrc67

First of all thanks so much for your fantastic work, I really love it in particular ISO enhancements!

I would like to point out an idea.

I noticed few places where to store settings (in example autoiso in "Shot without CF", Auto Adjust Exposure in PAL/NTSC video format)
Couldn't be useful to destiny the last picture style User3 to store settings?
This way you could store 4 settings also with multiple values.

Thanks again 😀
Bye!

Zibri

HINT for all:

go grab WINIMAGE (for pc) and copy your bootable ( + autoexec) and empty card.
then use the image to copy back on as many card as you like.. the image will resize automatically.
No hassle.

Check the size of the CF. The instructions for 4GB (fat16) and > 4GB (fat32) Cards differ, just incase u may have missed that part.
