Great thanks, Mr.Schulz ;D

I patched my old 7D a different way than this, so I didn't know all these. I will give it a try when I can get my hands on my new 7D in a couple of days. Thanks again.

I sold my old 7D and just got a new 7D, just to prove that I am a big 7D fan. But problem comes that there is a Ver.2 sign on the box, and, after some searching the internet, I have found that Ver.2 7D might brick the camera if flashing to 1.x firmwares. So I am wondering if there is any solution that I need not flash back to fw1.2.3, in order to get autoboot ML? Thanks in advance.

The 1dx owners don't know what they're missing, ml already has expo lock, the stable 2.3 ml or the auto_iso module have unlimited min. shutter speed in av (and aperture in tv), the module also has ec on m :-)

I didn't know that, for I used to only use the rec_raw.mo module. Start willing to try already. Wish somebody will tell me that if there is anyway that I can start ML without flashing the camera's firmware.

These 3 features look nice, wish they can come down to 7D

For your information, with my Lexar 800x, which was from the internet, I have got 42mb/s sustainable, and that speed translates to 1344 x 756 by aspect of 16:9, if it means anything to anybody. Lexar's 800x and 1000x's write speed differentiates a lot seemingly.

I dont understand very well how the black points / white points / dynamic ranges are decided for the respective cameras, and how is the lumination level converted to bit depth. I have not enough knowledge to understand codes. :-\

Do not rule out the mighty Canon EF-S 10-22! It's perfectly fine for the 7D. It's one of my most appreciated UWA (not fish eye) lenses.  ;) Millimeters are the same for crop and FF. And 4 mm is a lot on the wide end.

Edit: actually, before ML it was the main reason why my 7D was still around!

Yeah I forgot that mighty EF-S10-22, x4.2 it looks very handy from midrange to portrait, but the price tag can make some of us whine about it. Anybody likes to comment on the cheaper substitutes?

7D's x5 zoom mode is a total lost in the wild angle realm, but gains incrediblely in the long range, bird/plane shooters must like it.

Btw, the latest Britom's build has no greyscale 1:1 mode when zooms 5x

Actually it is something like 8 x 4 = 40 mm, because you can get maximum 3x in 7D's 5X mode, most if not all CF cards today cannot reach 3x continuously, but by a smaller aspect, you can get something like 2k, 5184 / 2000 = 2.592, 2.592 x 1.6 = 4.147, and 4.2 x 8 = 33.2 mm

But, 8mm is a fisheye, the widest non-fisheye is the 14mm full-frame lense, which I heard from rumor.

I tried a couple of times using h.264 with sound successfully, you only need to disable the rawrec module in the ML menu (grey it out), then  everything is just almost the same.

The latest Britom's build is quite stable to me, test shooting raw one afternoon, no ERR encountered. Cannot remember any significant issues, but the write speed varies a lot.

My bad, EV value is float. But there must be some formula to change EV value to bit grades.

Second thought (actually third ;D), the DIGICs are already doing the best they can, so...forget about it. Sorry for the bothering.

I was a little upset about  the vertical lines in RAW, its obvious pattern apparently indicated that those vertical lines were read related noise. But how come that the original CR2 doesn't have those vertical lines?

When reading raw.c and raw.h, some questions popped up into my mind. One of the biggest one of them is  like that, why the ev values are in float? Aren't EV values are in unsigned int instead? But I was not familiar with coding, image capturing and 7D project, so there was no immediate answer that I could find as the knowledge in these fields has failed me. Please forgive my ignorance.

One thought, I don't know how you get the raw data from, 10x zoom might suggest that it might be that the full resolution is filling that buffer, so the buffer that you guys set to capture raw might be wrong size--just wild guess.

Cheers

I remember somewhere A1ex have said that the RAW has some over-dark areas? A few pages ahead, if I understand correctly.

Say, is it possible that we can have some un-precooked RAW someday?

When reading 1%'s code, suddenly something comes into my mind. Is it possible to load the whole ML thing into the system memory so to eliminate the need to refer back to CF--assuming that it is the case now, because I don't know if all CF card can do read and write simultaneously

Good luck, then 8)

I know nothing about the DryOS, but the Linux built-in the file systems into its kernel or build it as a module, and my wildest guess is that the DryOS is also like this, so to mount it, I blindly believe, you need to add the module to the kernel first.  8)

Btw, is there a MLV 2 CDNG Windows software? AE's processing speed for DNG is anguishing.

Run boot off fir if you want no boot flag. You don't *have* to autoboot if you're a glutton for button pressing.

10x yuv is broken. You have to press play to go back to 1x. You can record in the frozen zoom too without issue (except no preview).

I think what I mean was that pressing the zoom key while recording RAW video, the camera showed an ERR message on the shoulder screen and then freezed and crashed. Please excuse my bad English.

I am using Britom's Sep 10 build from the repo (which has playback RAW video function in the RawVideo submenu), when I shoot RAW video, pressing the Zoom-in Key ( the "+" key) will make the camera freeze.

Pardon me for interrupting. I am using one of 1%'s builds (I don't quite remember which one exactly, because there are so many of them, it is the one that cannot play back raw video), initially it has got plenty of ERR on the shoulder screen, after overhearing that 1%'s camera, which is equipment with CF cards faster than mine), was working fine,  I started to suspect that those crashes are related to write speed, so I reduced to the maximum resolution that the old firmware, which is before the great FPS override,  can sport with my poor old CF cards, and the result was a bit encouraging, only 1 ERR error the whole afternoon shooting for fun. And later I tried to boot the camera with a large preload like 512mb, the ERR error was just gone, with several test shots. It was a miracle. Thanks 1% for your good work.

Btw, I found that the autoexec.fir only needs to be flashed once, and the camera just FPS overrides fine afterwards.

corrects some grammar
