Canon 5d Mark II Problems (NEED HELP)

Hey all,

Just got a Canon 5d Mark II and I have two questions.

First, I have a 24-105mm lens. Now, when I first began shooting, I had it in Manual. Somehow in the process of shooting over the course of some days, it had moved to Auto on the lens and I didn't notice. I began Manual focusing in Auto focus. And at one point, where the lens should stop, it went past. That's when I noticed there was a problem. I changed it back to manual and while the lens works fine, it seems that it doesn't stop as hard on Manual as it used to. Is this a serious problem? I won't be touching it back to Auto regardless and checking everytime for now on.

Second, when I shoot video and pictures, there is a faint red line on the picture.

Watch my video here: http://vimeo.com/18230​633

Near the top right corner, there is a faint red line that extends from the end of the picture slightly into the picture. When the lens cap is on, it's a distinct red line. This was apparent when I first got the camera and while it's barely noticeable it's something I don't want. Suggestions? Is this normal?

Thank you for all the help!!!

Not too sure about your lens problem, but there is no way for your lens to be moved from manual focus to auto focus by itself as you physically need to move the switch to change it.

As for your faint red line on the top right side of your video. I can see it pretty well. I would think that it is a defect in the sensor. Does this happen in photos as well? If it does I would send it in to Canon and see what they say. If it is new then I would return it to the place you bought it from and get another body.

Take Care,
Cheers, Patrick

Patrick,

I know what you mean by switching MF to AF to achieve auto focus. In this case, I was on auto focus, but could still turn the focus wheel. I didn't know that I was on auto focus though and I was wondering if I'm trying to manually focus in auto focus, can I screw up the lens (since at one point I went past the place where the wheel turn stops)?

As for the faint red line, I think there's something wrong with the body or the lens. I'm not exactly sure which it could be though. Is there a way I could check to make sure it's either? Thank you. And the faint line was there from the very beginning.

Thanks again!

Unless I am mistaken the 24-105 has a USM ring motor that allows full time manual focus - i.e. even on autofocus you can full time manual focus without breaking the lense.

You can definitely do it on the 24-70 & 70-200
The manual for the lens will also state that.

Lens is full-time manual--okay to manually focus while in auto-focus. I do it all the time. I have not watched the video, but I would think that if there is a problem, it isn't going to be with the lens. A red line sounds like a problem with the sensor--or with the compact flash card. (this assumes that there isn't a large piece of red tape over part of the lens!)

Thanks, JoeW and DelevCM.

I'm not worried about the lens anymore so thank you for that information.

As for the video, JoeW, if you could just see the video for a bit, it's only 2 minutes long and while I think everyone is right about the sensor. It would be great if you could see it and maybe decide then.

Thanks.

A question on the manual focus of the 24-105 when in auto - doesn't the autofocus take over after you have manually focused, and you are right back to where you started?

If the camera focusses when you half-press the shutter button and you have the lens set on AF then the following should be the case:

- half-press the shutter button to focus, at this point you can then override the auto-focus and manually focus yourself (still keeping the shutter button half-pressed). You can then fully press the shutter button to take the picture. If you release the shutter button after you have manually focussed and press it again, it will auto-focus again.

- if you manually focus then press the shutter button, the auto-focus will kick in and focus where it thinks best.

Once you get to grips with how the camera and lens deals with focus its pretty easy but if you want to keep it straightforward only MF when the lens is on MF and AF when on AF.

Cheers.

Any other thoughts on the red line?

In terms of it being either the body or the lens?

Thank you!

I can't see the line in the video you linked... maybe I'm blind... or it got lost when the video was scaled down.

Any chance you can copy a frame from the video using ZoomBrowser Explorer or whatever it's called (check Canon disc ) and post a single frame?

DetlevCM, I can't seem to get a great frame for this right now that wants to be attached.

I'll tell you this though. Go through the video. At :13, stop the video when he's putting his beer down. When his sideburns are right along the black, stop the video. You should be able to see a faint line if you blow it up.

Thank you.

Easier said than done...
I have a feeling I did see something like a short line -

HTTP response: NOT FOUND | MIME changed to 'image/png'

Some users have found that sensor pixel issues may be resolved by a manual sensor clean (longer than a
minute) with the body cap on.

What version firmware do you currently have? Most current is 2.0.8. If I recall most of the firmware updates fixed various video bugs.

Just a shot in the dark.....

This?

It would be really good if you could go through it frame by frame (and yes, I know it's tedious, sorry) and screenshot it.

That line could be a funny light source - I've had images show a horizontal line due to a light source - on that note, it's always horizontal, in landscape orientation & in portrait orientation.

Edit:
It could, in your case, also be a codec issue -> i.e. nothing you can do about it, except retouch every frame and complain to Canon.

I could do a manual sensor clean and my firmware at this point is 2.0.8.

DetlevCM, I'm sorry if that caused you trouble, but I appreciate you looking at it. Now you said it may be a light source, but this is in every picture and video that I've taken thus far in different lights.

Luckily, I just got it within the last month so I could probably get a new body within that time period. Or if I have insurance, that should be able to fix the body or at least give me a new one, no? Thanks.
