Eos 400d ( Rebel XTI )

[scout7]

Feature Request

I'd like to request a "tap and release" mode for the Av button.  Tapping the Av button would toggle between modes for the scroll wheel (e.g. between aperture and shutter speed in manual mode) and not require the user to hold the Av button down while using the scroll wheel for either setting.  Ideally the currently active setting would be remembered between shutter activations.

PS: a big thank you to everyone involved in this project.  I'm very thankful for the ability to get Auto-ISO and ISO3200 on my XTi.  (It actually influenced which camera I bought!)

7. Factory Menu
8. Focus Frame pattern

excuse me sir,

If No mount any lens in 400D, it is "F00" in screen. And it can't chang the "F00" value by "AV" model at that time.

Is it impossible to add a funtion: when no lens mounted, the 400D can chang the "F00" such as a len mounted?


......

what is that I means is that:
when mounted a OLD lens which use Manual-focus only, It can not speak a Warning sound form the 400D when on foucs.
if a crack can Cheat the 400D did not distinguish whether the lens mounted or not, or mounted forever, the 400D would auto AF Confirm when use Manual-focus on foucs by old lens without a Electronic-Transfer-Ring.

......

If that a software way to Hack Canon EOS 400D to confirm focus with all lenses, permanently?

Can you give some example which canon lens that we can mount?

HELLO.

New forum member here, and lover of this XTi patch.
It's been working great, giving me the expanded iso I was hoping for.

A couple questions though.... I hope someone can help.

I learned that I can not delete the AUTOEXEC.BIN from my card ever because then the patch does not work. Correct?
Well now, after I shoot some pics and take them off of my card, I can't seem to clear the storage space after removing them.

The files don't appear to be on the CF anymore, but I have limited frames left, as if the card is still full.

If I format, well, then I lose the AUTOEXEC.BIN, correct?

How can I clear space on my card and keep the .bin file in place?

This is probably really simple, and I am just overlooking it.

Just delete all the images with you 400d. You can recopy AUTOEXEC.BIN in CF by the card reader If It was formatted by accident/necessity.

Thanks for all who are working on this camera.

Canon EOS 400D hack.

Can you give some example which canon lens that we can mount?

ok: like zeiss 135mm f2.8 , it can be mounted by a M42-EFs ring, manual focus , can be use very well, the color was wonderful, but not confirm focus by 400D.

Feature Request

This is discussed before in the thread. It would be nice to be able to do 5 or 7 shots in AEB. That will be a great addition.

Also would it be possible to introduce AF microadjustment?

I have recently installed the hack to my sweet 400d and it works perfectly. Thanks a lot to everyone involved in getting this to work. You guys rock!!

[Zibri]

Come on GUYS (thaibv and fedelsa et al) please, sell the 400D and get a 550D (I did.. it's a must upgrade)

Then start working on it.. I can't stand the magiclantern...

This would be a great wee hack - I have the same problem - I have some nice old pentax screw mount lenses, and an adapter to mount them on the canon mount, but the problem is the focus sensor doesnt go at all!

It would make it soo much easier to use manual lenses if the focus indicator still worked!

Anyway, this is a fantastic hack guys -I really appreciate the time & effort you've put into keeping these older cameras "up there" capability wise.  I love my spot metering, and often use the iso3200 for checking framing for night shots..

I know, but the bootloader is not even on the CF card, but on the camera. I want to flash the bootloader back to original state.

the change and continue running even looking for a file on the CF card.

Flash again with the Canon original Firmware.

Others have reported that does not restore the boot flag.

This really don't change bootflag, tryed it last night and camera stil reads fw from card when powered  on.

Has anyone got an answer for this? I'd like to be able to completely remove any trace of CHDK having been used on my camera. However, even if I reinstall the latest Canon Firmware the camera will still read the Bootable Card with the Autoexec.bin file and go ahead and execute it. How can I reverse whatever the testfir.fir did with my camera? I did a lot of reading and thought that this whole hack thing was completely reversible but that doesn't seem to be the case. I certainly think it's cool to be able to get additional ISO's, spotmetering and what not but I'd also like to be able to completely reset my camera to it's original factory condition. Advice anyone?

Unlock Guide:

6. download cardtricks 1.45 : http://chdk.setepontos.com/index.php/topic,4214.0.html (first download link). Run it to self extract the archive. Run the binary extracted, choose CF drive, tick "cf boot sector" and then click "make bootable."

this step can be done on linux or mac os as described here: http://magiclantern.wikia.com/wiki/550D

i did it on linux and it works for me, just remember to format the card only on the camera
(it is fat16)

Code: [Select]

dev=/dev/sdb1
echo EOS_DEVELOP | dd of="$dev" bs=1 seek=43 count=11
echo BOOTDISK | dd of="$dev" bs=1 seek=64 count=8

note: "dd" is available on windows too - http://www.chrysocome.net/dd

perhaps you could update the post on page 26 - http://chdk.setepontos.com/index.php/topic,3290.msg49910.html#msg49910
