hello
if you have seen hd-video of 5d mk2 or sx 1IS( sx110 IS)-they have indentical chip- you will forget all these hacks here. ok, the affordable sx 1 IS has 28mm zoom only. if you can wait we will see HD-version of panasonic lumix g1 = G2. 7-14mm lens, 20/1.7 wow (multiply by 2x) 14-28, 40/1.7 isnt this impressive?

I fully agree with EmKlap and encourage you to share your knowledge.
EmKlap and me have been working on the 300D UnDutchables edition and we never faced any action from Canon. You can just share general knowledge, e.g. in source form, without distributing the actual binaries or fir files. In the end, someone else might do this based on your work.
But collaboration is the power of open source.

If your work is not based on chdk but rather on modified fir files, the collaboration might be hosted on the same forum where we continued the 300D work started by Wasia, same kind of situation. If it is based on chdk, it better stay here.

Yeah, maybe even a lot more than 'a while'. I really have a lot of stuff to do and I have very little time for CHDK-ish stuff. In fact, I haven't really touched any of it in the last month or so. I really can't tell when I'm able to work on this again but it could be months... maybe never, because I'm not really sure about the legality of this (won't work without Canon encryption).

I understand your worries wrt legality  :'(. The same applied when developing the "improved" firmware for the 300D, but there where no actions taken by Canon. They are probably to busy developing new camera's and the minority that use non-canon firmware is minimal an would not damage mich (if any).

If you don't have the time to develope yourself, at least spread your knowledge so that other (with time) can take over from where you left. I really would like to know how the decrypt the payload in the FW and to see if modification of the existing FW is possible.

So keep up the good work and spread your knowledge :)

      - Some language strings seem to be present but this may be common to all EOS cameras. I hope I can get the necessary code from the 1D3 but I don't know how to decrypt the main payload of .fir files yet.
      - Own implementation might be possible by just adjusting focus after focus lock.
wow
the micro-adjustament would be awesome
i would love to have on the 40D
i guess it could be probability, likelihood


i'm  available for every kind of help

thanks

I did not see micro adjustment strings in the 400D code, nor 20D and 300D.
I assume it is a novel feature, maybe the 50D can help here and if we are lucky, the 40D has some preparation already.
I guess this code is developed on a certain source base and at release time, marketing decides which of the available features make it into this years product and which need to wait.

what's the meaning  just adjusting focus after focus lock.

could be probability tune up lens like the 50D , i mean for each lens to avoid problem of back or front focus?



it could be a nice feature change  the info color , the black & white could be changed with other hue

thanks

if you ask me, microadjustment takes too much time for practicality's sake. for me, this is useful for macros, still life, and other similar subjects - subjects that don't move and you are in a situation wherein there is no time pressure. when you are doing, say, weddings or events, this is useless. it would be better to use a stop or two narrower of an aperture to compensate - which always helps keep your images sharp.

Great photography tip, and thank you, but I'd still like to have more features/options available to me where possible. Don't get me wrong, I love my 40D as-is, but more/better features for free isn't a bad thing, right? ;-)

Dataghost, still under pressure? May we see something about video on 40D in next... 6-10 months? Of course, take it easy. Thanks for your very useful work

well his work is for free
if you want to help you can make a donation

he is not obliged, indebted, constrained to release his add-in


everything Dataghost will do , it would be a gift

the best thing i guess it's  the micro -adjustment
becasue the 40D is a good camera but suffers of Back focus

hi there,

I had an Idea an if it would be able to include this in the 40D that would be really helpfull. The 40D has a safty shift function which allows the camera to adapt to rapid light changes and it changes the shutter speed or aperture by itself to match the enviromental conditions. The problem is that you can't set a limit, so the camera goes down to a second or less if necessary. Is it possible to write a feature which alows to set a limit (as the 1d Mark III is able to do) and so keep the kamera from going to a shutter speed that can't be handheld.

There is also the same function for changing the ISO by itself in a certain range, the 40D doesn't have that included (but the 1d mk III), so that would be really cool too.

I hope it's understandable what I'm suggesting... ;o)
