Question about Cameras

1 Answer

I have a Canon 20D with a IS 70-300mm lens that after a dozen or so photos won't focus/shoot. I just got my hands on both the lens and 20D (bought it from a good friend which says this has never happend before) AND I don't know what the problem. I think that the electrical contact is not working proper. What do you think?

If it won't focus, won't trip the shutter, and sometimes won't turn off, the shutter release switch is defective and needs to be replaced. This is not user replaceable, and will cost about $125 at a repair shop.

My canon 20D autofocus doesn't work... can you tell me haw to do?? thanks..


Make sure your camera is set to Auto mode (top left knob). Check your lens and make sure it is switched to "auto" and not "manual"(sliding switch near base of lens). Make sure your lens can rotate and move without being obstructed. Clean the lens contact by removing the lens and use 99% alcohol or lens cleaner sparingly to clean off the metal contacts.
You can also check your viewfinder focus, it has a small dial upper right, that you can fine tune to focus to your own eyesight. If it is way off, your view will always appear to be out of focus.
Hope that helps.

I got error 099, before I was getting error 05. and the flash dos not open canon EOS 20D


I also get the error 99 message and cannot take any photos... I have been able to solve this problem by taking out the batterys and wiping down the connectors on both the batterys and the connecters in the motordrive with a lens cloth. keep the lens cloth on hand when shooting. It may be that either oils, or dirt has gotten onto the connectors. I hope this helps.

Blurred subject in middle of photo


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.

Photos are not sharp


I would look beyond the camara and suspect that the computer is tired or overloaded. This would be a more logical point of defining the trouble and cheaper than suspecting your fine camara and expertise. If you still think it is the camara take it off the auto focus for a few weeks and see if you still get problem shots. If So take the puppy in for an overhaul of the timing shutter mechanism. It may just have a fuzz ball or rather hairball problem that only momentarilly and intermitintly snags. If it is not the auto focus then how about a different computer program choice?? Photo files eat up a lot of space and unless you have one computer that is totally dedicated to just the storage fixing and printing of the pictures you may simply have a RAM vs PIXEL problem. Try off loading some onto disc for storage instead of keeping them all on the machine. If they print out better in quality than you see on your screen then it may be your monitor that needs to be reset to handle fine detail in the contrast settings. You may have to upgrade this equipment, which I would for the TAX BREAK.

I have a Canon 20D camera that I use with two lenses. The lens that I have most of my problems with is the 28-70 f2.8 red ring lens. When focusing It always seems to focus on what is behind the subject. No...


This is quite a well known problem called 'back focusing' there is little that can really be done about it, except if the camera is under warrnty you can send it in and they will do some laser alignment that fixes the problem, it would be worth a call to canon and getting a price quote on a service. Also it seems to be worse with some particuar lenses,

"busy" Error


check your firmware version and update if necessary. Usually you get the "busy" message when your camera is writing to the card and it's possible the card isn't quite right - a format should fix it. Alternatately you might try a different CF card to see if the problem goes away. Good luck!

Focusing Problems


* Get AF off the shutter release and onto the * button using the custom function. * Use the center focus point only. Force yourself to pick what you want in focus, AF, then recompose and shoot, a habit far more effective than computer driven multiple AF points for just about everything. * AF performance degrades in low light no matter what camera you own. This is life. At least if you control the when/where of AF, you can try and choose high contrast points in the scene to focus on, points that will help mitigate the low light. * Not sure if this applies to you, but it does apply to many a pixel peeper...if something prints sharp at 8x10 or 11x14 then AF has succeeded even if it's a little off at 100% in Photoshop. AF is not perfect and the tolerances are not necessarily up to producing 40" enlargements, which is what 100% in Photoshop is. Having said that, in good lighting with good target contrast the AF on your 20D often will nail focus so perfectly that it will hold up even at 40".
