Canon digital rebel focusing problems


I'am having problems with my digital rebel taking sharp pictures. I snaped some at a friends wedding (I was not the photographer hired) but alot of them came out a bit blurry. I'am keeping an eye on the focusing points which alot of times don't seem to want to focus on the subject. But I'am switching the focus points to where I want them and the focus confirmation circle in the viewfinder is not blinking which indicates in focus. Never had that problem with my film camera. Anyhow I remember reading about others having the same problem but cannot find the post. I believe someone even sent theirs back to canon. I used a tripod on some of the shots and they still came out blurry. Shutter speed was equiv. to the lens I was using so I don't understand what's going on. I need to be able to take candid shots without worrying but now I'am not sure I feel confident in this camera. I don't believe it's me that is the problem as I have been using canon SLR's for awhile now. Any advice or anyone else experiencing this problem with your digital rebel?????

  Have you had the same problem with more than one lens? At least that would help to confirm if it is a lens problem or a camera problem.

  I'll try to pay more attention to each lens but I think it's more with the one that came with the camera. the 18-55mm. The fact that I also got blurry ones when it was on the tripod worries me as well. I will have to search for the discussion I saw awhile ago about people having the same problems with that camera.
I have also been getting an "error 02" message witch has to do with the cf card according to the manual but why would there be a problem with a new card and fairly new camera already?

Joe Jarosz   Hi Kristi,
a few things. When you say blurry, do you mean out of focus, or just soft focus. Can you post a few picture examples? What is the sharpness set for in the camera settings? Its possible to bump that up a little to sharpen up the image some, but the rebel does tend to put out a softer image which can be cleaned up in photoshop nicely using the unsharp mask. You can even go to Canon's web page and go the the Rebel page, support, and go through the image sharpness problem and it will walk you through a few things. Its possible its the lens as well, if thats the $100 lens that comes with the base rebel, its an ok lens, but not the best quality. If you have another lens of higher quality, it would be a good comparison.

  This is not the first time this issue has come up for the dig.reb. xt. I'm curious, are you shooting jpg or RAW?

  They are just not sharp. Either way I'am not happy with some of the results I got. When I view them on the LCD screen and zoom in they are not sharp. Also when I view them in PS at actual pixels they are blurry. So if someone wanted one enlarged it would not look good. I've tried unsharp mask on some and they are to blurry to correct. I've did a couple shoots last week of babies and those turned out beautiful and very sharp. I'am shooting in jpg large fine setting. Ok I took a break and looked at my camera and which settings I used on the shots. I see alot of my shutter speeds are pretty close to my focal length. Not lower but close to. Are digitals a little more touchy when it comes to camera shake? WIth my film camera I have shot with a shutter speed under my focal length and no camera shake.
Let me know if this is a digital thing! Thanks again everyone for all your help.

Barbara Handy   hi kristi,

i'm having exactly the same problem with my digital rebel. I love the picture quality of the photos that do come out, but a lot of the time the camera is useless for snapshots (which is what I mainly use it for) . I got rid of the multi-point focussing (just using the 1 pont in the center), I always make sure the focus indicator is solid, but sometimes i'm lucky if I have one perfectly focused shot per batch. I have read that for other people who got digital slrs (not necessarily the canon) the percentage of focused shots goes down, but for me the extent of this is ridiculous considering the camera cost $1000 when I bought it. I shoot jpegs in large/fine as well.

Joe Jarosz   Can one of you post an example picture? I had the rebel, then moved to the 20D. While the rebel sometimes put out soft pictures, if you don't want to play with that in photoshop, you can change the in camera sharpness. But really the pictures were not out of focus unless I used the wrong focus point for example. Can you also tell us what your exposure settings are?

Joe Jarosz   Hi Shannon, to me it looks like the fence in the background is in focus but not the horse. Did you take this as a jpg or RAW??

Joe Jarosz   Also keep in mind when shooting at 2.8, your depth of field will be limited, so if for some reason you focused on the fence by mistake, anything in front of that, in this case the horse, will be out of focus.

  Sharon, seems you have a mixture of problems here, firstly its pretty dark forcing you to use f2.8 at iso 800, as mentioned above the depth of field at 200mm f2.8 is going to be shallow you might get a whole bird in focus but a horse! if you had focused on the horses head you may just get the rider sharp also at f2.8, also 1/200 sec shutter speed is only just the limit to lose camera shake at the 200mm end of your zoom, what with the horse and your camera moving you going to get a mix of both problems, only real way to do this bettter is daylight, does`nt matter if you shoot Raw or jpgs if it wasnt captured sharp you wont sharpen it with software. I dont no how many shots you took but you would increase your chances of a sharp image if you use servo and take 4-5 shot at a time

Sharon Barberee   Servo ? Wheres that on a 300D ? So in essence I should maybe focus on the face , what f-stop would you suggest ? Thanks, You have no idea how much help you have been....

Sharon, I have a rebel xt I assume you have servo on the 300d, it enables you to take a burst of images by just holding the shutter relase down, the xt will take 3 frames a second the button to change it is next to the view finder on mine, also there is servo focus this will adjust the focus and "track" the moving subject, you have to use what f stop the light allows, but taking more shots will give you more chance of sucsess, have a read of your manual, or im sure one of the many rebel users on bp can help

Joe Jarosz   Sharon, as long as you are using RAW, it would be interesting to load the Canon EOS viewer utility and see what focus point was used and where in the frame it is. I'd be happy to do that for you if you don't have that utility and you are comfortable.

  Re. Servo, let's not mix terms.

Drive mode: Single-frame, Continuous shooting, Self-timer/Remote control
It's Continuous shooting that allows the user to take sequence shots.

AF mode: One Shot, AI Focus, AI Servo
The AI Servo allows the user to press the button down halfway so that the AF focusing system can track the moving object. Thus, when the user fully depresses the button the time interval between focus and shutter release is shortened.

For the 300D check out p.123 of the instruction manual.
http://www.cleaningdigitalcameras.com/EOSDR300DIM-EN.pdf

For the 350D it's on p.70.

  The complications of a digital camera are overwhelming, but here's a solution that has helped me. I only use the AF area in the center of the camera, and shoot in the Program mode, so that I can easily shift to other AF areas if I need to. You can do this while shooting in the Full-Auto mode. I'm gradually making photos that are approaching the quality I took with my Canon Elan, but it's taking awhile. The main complaint I have with this camera is how your image through the lens gets cropped a bit when it appears on the LCD. Don't know how to get around this...!

  Ok, I went to Europe, and most of my images look slightly soft/ and/or they're grainy. I've shot at 1600 before without this severe grain, so don't know if it's the airport scanner (some of my cards went through with my checked luggage) or what...
