Last one for tonight:

TL-card mounted:
1) 18-55 IS II -> Focus ok.
2) EF 100/2.8 IS L -> Focus ok
3) 18-55 IS II -> Focus ok. ...   :o
4) 10-22 -> Focus hunt. Same with other lenses, except 18-55 IS II and 100/2.8 IS L ...

EDIT: Replace 100/2.8 IS L with 18-55 IS II as 2nd lens and focus hunt will occur, too.
EDITEDIT: Blown the dust of an EF-S 55-250 IS II and now I have a third lens triggering focus hunt for lenses mounted afterwards.
Wild guess: Issue when newer Canon lenses are combined with older ones, including third party?

Ciao

you made my day!
Lenschanging causes this Error, not ML ;D, changing with camera switched off (what I never do...) does not help
when I had it the first time in 10/2012 I changed before from 70-200/2,8-IS-II to 17-55/2,8 IS
which now produces the failure again.
removing battery or reloading card helps.

and now I have a wish for Christmas 8)

I think you're wrong:
- TL-card inserted -> Focus hunt with older lens after newer Canon lenses (18-55 IS II, 55-250 IS II, 100/2.8 L IS) were mounted
- TL-card inserted, SET pressed at startup -> same
- TL-card removed -> Everythings just fine, no focus hunt.

hey that was a joke :-)  8)
without ML that never happens, but I am glad to know when it happens,
and that the developers can reproduce it now

Walter Schulz

Is the information about bug occuring with 70-200/2.8 IS L II a joke, too?
Haven't seen confirmation from devs yet.

Unfortunately I could not reproduce the bug... :(

What I tried:
- I used Britom's build 29SEP2013 (which EOScard automatically downloads*)
- lenses: 28-80L, 10-22, 100L, 300/2.8L
- AF modes: spot AF, 19 point AF
- AI servo

I can change the lens in any order but the focus is still working in both AF mode.

Couldn't reproduce the bug in AI Servo mode, either.
Have you tried "One Shot"?

No. But I've never used One Shot mode on my camera (I had this bug in AI Servo).

EDIT:

Could you reproduce the bug with the 100L and the 10-22 and Britom's build 29SEP2013 in One Shot mode?

So I supposed as you said you lost some action shots.
Well, I have a reproducable bug and another one (your's) I'm quite now not able to reproduce.
Are you able to confirm the first problem?

Will try it with Britom's build asap.

Ciao, Walter

Walter Schulz

Error happens with 10-22 and 100L using Britom's 29th September build.
10-22 will not give focus confirmation in One Shot mode after dismounting 100L.

no joke, and with a lot other Lenses too (Canon 50/1.4, Canon 18-135(old), Canon 10-22)
occuring today with tragiclantern-Tragic.2013Nov14.7D203 in Ai-Servo using single AF-point
and one year ago on 21.10.2012 (I guess with alpha2)

Walter Schulz

I'm not able to reproduce the bug in AI Servo regardless which AF point selection mode is used.

Hi Folks,

been following this thread a Long time, all very interesting stuff and huge appreciation for all those who are putting in their time and hard work.

I finally got round to getting a 1000x card, a Transcend 64Gb UDMA7, which is not too much more expensive than a Komputerbay (here in the UK at least) and is less of a 'gamble'. It works well and can record 1080 25P continuous using both 29th Sept and 8th Dec builds (only ones I have tested so far).

I have a question-

I've been using Dec 2012 2.03 Alpha 2 for 7D up till now, and recently tried the 'movie restart' feature, which doesn't appear to work?( thread)

Do any of the TL builds also allow recording to H.264? without crashing, on card end? And working Movie Restart?

Thanks again for all the hard work,

neil

neilpercy

Ok, answered my own question re: Movie Restart.

Using Dec 8th Build recording h.264 Movie restart is working in limited testing.

Are there still issues with camera freeze/crash if recording gets to 'Card Full'??

Quick question. I've just got my komputerbay 64gb 1000x. What's normally the fastest write speed you see? I'm getting approx 80mB/s trying to write 1080p25.

In case anyone is interested in 7D+MLV+1x+GD on+focus peaking...

I spent a few hours today building and testing different versions of tragic-lantern-6d from the past few weeks to try and find out which change caused the performance drop in MLV with GD on and focus peaking.

It turned out to be 10350:c849adc8291b, which lowered the writer_thread task priority from 0x05 to 0x1C in order to fix the pink frame problems. However, that task priority seems to be lower than almost every other task in the system, so it also reduced the write performance in the focus peaking case.

I played around with some different values against the current hg tip. For me, 0x10 still suffered pink frames, but 0x12 or 0x15 both seemed to give no pink/corrupted frames, and enough write performance for 16:9 1728x972 1x with GD on and focus peaking.

The diff looks something like this:

(Since I don't have 5d2 or 50d, I can't test if this change is working for them. It might need a special 7d-only block.)

Could you describe how do you reproduce the bug?

its easy:
set single focus point (e.g. to the leftmost one)
mount Lens A
focus
change to Lens B
-> focus hunts
mount Lens A or take out battery or CF
- >focus works


which Lenses do you have?

Walter Schulz

About AF hunt bug.
Played again with AI Servo mode. Latest observations:

- Single Point or Spot AF with central AF point activated: Wasn't able to reproduce the bug
Changed to border AF point (right side): AF acts erratic. Most of the time AF will miss to focus selected area.

Not like One Shot where AF will hunt all the time in all AF point selection modes.

Ciao
Walter

PS: 10-22 is not the best choice as "Lens A" in my opinion. View finder might fool you because DOF. Well, it's an ultrawide lens ...

StefanKeller.AC

the central sensor always works
do not rely on viewfinder, just try to focus from near to far (or vice versa)
I tried:
  a fresh ML without own settings
  switch of AFMA
-> same behavior

Yesterday I tried to update the ML firmware decided to do everything with a "clean" card.
It turned out that EOScard does not work on my computer.
I tried to download the latest version of http://pel.hu/down/EOScard.exe,
but the site is unavailable. This is a problem on my side?

Hi guys, how is the best cf card to record continous raw with the 7d? Appart of the komputerbay, maybe the lexar 1000x or the scandisk extreme pro 160mps?

Thanks in advance  :)

flofifull

I'm back with a small one...
With the VAF-7D, I filmed the Cap Griz Nez in France in 1728 x 972 pixels in RAW format. Much less moire, and the latest ML'S builds are super stable.
