DiginAutofucus issues

Does anyone know why an previously great Canon Mark II would start to shoot soft pictures? The camera tells me that focus is good, but everything is slightly fuzzy, no defined focal point.

I woulndt ..for me digital photography looks like shit no matter what you do…the quality is gray and sad…I wonder what the hell do you do
to have those colours and sharpness . I have been more than 15 years taking pictures and recentely started with digital Canon 20D just for
a few news stories and …man its horrible!
People say that its like shooting slide…but I have been shooting slide all my life and SORRY its not true!
its cool that is fast but …at the end what rests is your work,…… in magazines books or what ever!
Any tips?
My man has two mark II ’s I will ask him if he has soft focus ….

Saludos

Valerie

Hi i am denis doyle valerie’s husband. Re mark II fuzzuness: Maybee you already know but should, in my opinion, go to parameters in camera functions and put contrast at + 1 and sharpen at 3. It takes away fuzziness without giving noise. cheers

Hi Denis, thanks for the suggestion, I’ll give it a try. It just seems that the camera was working better before, maybe my imagination, but in medium to low light focus is not sharp
And Valerie, I used to think like you, but the Mark II is a great camera besides my current issue. You must shoot raw files and be good with photo shop however. When peoplpe say it’s like shooting slide, I think they mean you have to expose like slide, that is under expose a bit. It is easier to bring out highlights than to bring down blown out parts of an image. Raw is the only way to go.

Hmm…depends on what you mean by fuzziness. You mean the pics arent sharp? A little or a lot?

The Mk II uses a CMOS chip which gives a result which is ever so slightly unsharp. Its then sorted in PSP by using a small amount of Unsharp Mask.

My advice would be to turn the sharpening off in camera, and do it in Photoshop. You get more control and an in camera sharpened Jpeg will have artifacts.

If the unsharpness is quite obvious, there may be another reason. Is it across all lenses?

As far as shooting slides goes…if you wanna see your slides published, they’re gonna have to be scanned. And so they become a second generation digital copy, as opposed to a first generation digital original from a digital camera…

Just food for thought.

hey Eros,

it could be a problem with your camera. the folks at sportsshooter have discussed it at length:

good luck wading through that, but i hope it helps….

Eros,

Both Nikon and Canon digital cameras seem to have a problem with softness in their chips. I’ve found that over time the chips seem to get out of alignment and backfocus or get “mushy.” This can be different than general softness but my guess would be that they’re similar problems. I just bought 2 20Ds this Spring and both had to be fixed this summer for profound backfocusing issues. I’ve used the MarkII in the past and found the same sudden softness issue. I would send them in to CPS if you’re a member and have them check the CMOS.

Eros, is the problem manifesting itself with all of your lenses?

Michael, I do believe it is all of my lenses, that would be a 16-35 and a 50.
Scott, it sounds like chip is a bit out of allignment. The images are mushy, even with a 50mm. some are much better than others, but nothing tack sharp. so do you just have to send the thing in twice a year to have it re-aligned> that sucks donkey balls

I dropped off my ‘mushy’ 1Ds + 20-70 + 70-200 at CPS in NJ yesterday. Can email an example of mushiness if anyone wants to compare. And can post CPS’ diagnostic if they give me one.

Eros,

Who knows how often you’d have to send it in… I have a friend who has sent every digital camera he’s gotten as soon as they come out of the box. I’ve seen that as I start noticing the mushyness or the backfocusing it usually means that sometime soon I’m about to loose a decent picture because of it. At first I start thinking, “maybe it’s me.” But in the end it’s usually the camera. I’d send it in to CPS as it won’t get better. I don’t know what happens with Canon after the warranty runs out. With NPS, they would always charge about $600 to fix it in the D1h/x series. When you notice that some frames are good and others aren’t that’s the telltale sign.

Yup. Donkey balls.

Chuck Westfall’s first response there addreses some possibilities to ponder.

Cheers Valerie! It was shot on a Canon 10D…there does seem to be a backfocussing issue with other Canon cameras like the 1D mkII, although I’ve never had this issue.
