Blurred subject in middle of photo

I have a Canon Rebel XT. I am shooting basketball games with a Canon 50 mm 1:1.8 lens. Lately, alot of my photos have the focal point blurred with the rest of the photo in focus. What have I done wrong? I have reset all my functions. Thanks!

    Silly question, but is the lens clean? I had this once and found a nice fingerprint from my son on the lens...

    There's no technical reason for the focal point not to be in focus!

I own Rebel XT and Canon 50mm f1.8 MKII lens with plastic mount and noticed many pictures with missed focus, either front or back focusing. Meaning objects slight forward or below the intended subject is in focus. I've sent my body and the lens to Canon for evaluation and thet adjusted my focus sensors on the body. I still have problems and there are many threads related to focusing on this camera with 50mm f1.8 that the sensors on this camera do not do so well with fast lens and prone to missed focus.
Test your camera's focusing ability with a book or magazine where you focus on just one specific line and see if it is truly in focus when you review the picture.

Action photos blurred using the zoom lens.


When shooting pictures, always check the length of the lens. Take the length in mm to decide how fast your shutter speed should be. When shooting 200 mm, the shutter speed should be at least 1/200 of a second. For a 400 mm it should be 1/400 of a second, and so on. With indoors sport, you need a lens with a huge aperture like 2,8 or better and a high ISO setting, to reach the speed needed for a long lens.
Modern lenses can have vibration reduction, and with these sometimes you can shoot 3 to 4 full stops sower.
A 200 mm lens with vibration reduction can be used then at 1/25 or even 1/15 of a second and still don't need to worry about motion blur.

I have a rebel xt 350D , using 75-300mm 5.6f lens to do some girls basketball photography inside a gym. Had camera set on: ISO 1600, M mode, 5.6f, 200 shutter speed (that seem to set automatically), used...


Unless you were up close and personal, the built-in flash was your problem. Anything past about 15 feet and your picture will be dark. You would have been better off turning the flash off and using available light. Once the flash is off, you can set both aperture and shutter speed in M mode. Another choice would be to lay out some extra bucks and get a separate flash unit. They're much more powerful than the built-in flash.

There is a minimal focusing distance for all lenses. If you move closer to the subject than that distance then the camera won't focus on it. Check you lens manual for minimal focusing distance. It is 11 inches for Canon EF-S 18-55mm f/3.5-5.6 USM, for example.

Photos have a black band at top and bottom. This has never occurred before on my Canon EOS Rebel XT. I use auto mode for all functions and have not changed any menu settings.


If you use the lens in wide and the f lash is not wide as same (if the lens is 18 wide and the f lash is 28 wide ) you will not get good photo so if use 18 mm wide lens then use 18 mm wide f lash and ( i have told about external flash )

That's a big lens and for sports photography you are going to need a lot of light to ensure you can use a fast shutter speed to capture the action. Sports mode may do too much for you and you might want to try switching to a more manual mode. Try switching to Tv mode which gives shutter speed priority. Set the shutter speed to something around 1/150 or higher (1/200) which should be fast enough to freeze the action. Make sure the ISO is set to 200 or 400 for best results and see how you get on. This should stop any action based blur which would leave you with focus problems if the pictures are still blurry.

Canon Rebel XTI W/stabilizer lens


Hello bbridges,
Wow, you asked a REALLY open ended question. But here is a good starting point for Manual mode shooting.
Daytime (Full Sunlight) ISO: 100 (or 200-400 to capture fast motion)
F-Stop: Depends on how much depth of field (DOF) you want The lower the number, the blurrier the background. The higher the number, the more everything in the frame is in focus. Shutter Speed: Depends how much motion blur you want. The higher the number, the less blur you get.


Nighttime (Track Lights) ISO: 800-1600 F-stop: Again, depends on how much DOF you want Shutter Speed: Depends how much motion blur you want. The higher the number, the less blur you get.

Remember when you are panning to capture something in motion, keep on tracking (moving with the subject) even after you have released the shutter. It will help your stability reduce the chances of unintentional blurring.
My suggestion is to go to dpreview.com or stevesdigicams.com and do some rooting around in the forums. They both offer friendly and helpful advice. Also, check out webphotoschool.com
Better yet, experiment with your camera. Pick a time of day and take a series of photos of the same thing, and only change one setting at a time. Make note of what photo number you're on, and what setting you changed (and what it is). Then, when you look at the photos on your computer, match the photo numbers up with the chart you've made, and you'll begin to see a pattern. This is one of the faster ways to learn by trial-and-error. And, this method sure beats randomly shooting and just spinning the dials hoping to get something good. Try to predict the outcome of the shot before you shoot it. Ask yourself what the photo should look like (light? dark? just right? everything in focus, or just the subject?)
As for your lens, check to make sure the Auto Focus settings in your camera menu as well as on the camera are set correctly. And if all else fails, turn off the camera, remove the battery, remove the lens (in as dust-free environment as possible), and then put the lens back on, the battery back in, and turn the camera on again.
Happy shooting, and hope this helps!

Stabilizer


the lens you really need to own with the xt is the ultrasonic series which are the stabilized lenses-these lens run from 500-600 and up-not cheap. If your doing handheld telephoto w/no tripod can really make a difference-more important to spend this extra money on a lens from 75 mm and up as a wide angle or portrait lens really isn't as critical-stock lens on xt is a cheap quality lens-upgrade to a 75-300 image stabilized lens and you'll cover almost all your bases except wide angle which i would get a 10-22-good luck

Blur on night sports pictures


You are probably going to need a faster lens to get pictures like you want, like around the 1.* range. If you have the ASA at 1600 and aperture at the minimum in Av mode, try and keep the exposure time to 1/focal distance. Such as, if you are shooting 200 mm lens then maximum exposure time is 1/200 second. If you zoom out a bit to 50 mm then it may look better too. You may as well turn the megapixels down too because otherwise you'll just see the blur even more, I'd suggest 3.2 megapixels that will look good in 4x6 photos or on the web. Other than that, try and take pictures where the action is coming at you or going away. Get as close as possible too, so that you don't have to zoom as much. At the H.S. football games I go to it seems like they let anyone down near the field who has a big lens.

Blurred night time football pictures


The standard canon 75-300 lens is not considered a "fast" lens. Because of this, when zooming in on objects you are actually reducing the amount of light hitting the image sensor. Fast lenses cost $$$$. Just google "Canon L Glass" and you will see what I'm talking about. Try opening the field of view (zooming out) to allow more light to be absorbed bu the image senor. Crop your subject later in whatever software you use. You can also use one of the manual modes and up your f-stop to make the camera more sensitive to low-light conditions (higher f-stop means higher film speed.. higher film speed is how fast the "film"... aka image sensor absorbs the light. for action photos, faster film speed is key!!). have fun experimenting.
