Why does the camera not take a picture when using the 70-300 lens?

With just a little luck, the scratch is not too big, and you won't even see it on most pictures. Don't try to remove the scratch, because the front of the lens has a coating you can remove very easily. That will do more damage to the pictures then a scratch. You could contact a Canon repair centre, and ask what it would cost to replace the lens. I think it could set you back more then a new camera will cost, but always worth trying. If you don't see a thing on the pictures, leave everything as it is right now.
Only clean a lens with a lens pen, you can buy in every camera shop. In a camera shop you also can buy other cleaning suff special for lenses. Never use fluids that are not special for use on lenses, or you will also damage the lens.

Had the cam fallen down? It could be because the lens has dislocated from its location. (Presuming that you did not have this issue of blurry pictures before.) I would suggest you see if the lens is intact. If yes, try and put the camera on AUTO mode and shoot some portraits. If it still does not work, try manually setting a high shutter speed and see if u still get blurry pictures..

Any pictures you have taken in the past should be safely stored on the memory card. Make sure you copy them onto your computer to ensure you don't lose them while fiddling with your camera. You can use either an external card reader or you might be able to connect your camera to a computer using a USB cable.
A lens error is one that the average user can diagnose and fix. It usually requires a trained technician or worse (but sometimes cheaper), a replacement camera. You have already experienced that the camera will not take pictures with the lens error.
Good luck.

One of a few things might be happening
1. Photos being taken at high zoom (i.e. 200mm) are susceptible to camera shake, even though the lens is focusing properly. The solution here is use a tripod, zoom out, or steady yourself.
2. Photos being taken without flash when flash should really be used will result in motion blur (which is slightly different than camera shake). This is due to the camera using a longer shutter speed to let more light in, with the side effect being that objects will move while the shutter is open, blurring the picture. The solution here is to use a flash, or take pictures in better light.
3. The camera may be focusing on something other than what you intended.
3. If you are taking photos in good light with a steady hand, and the camera is choosing the correct subject to focus on, then yes, the lens could need readjusted, though this is not a very likely scenario.
If the lens is "hunting" for focus, that could be a sign that something is amiss.
A local camera shop can verify the accuracy of focus for your lens.

yours is a broken CCD-chip - like ours.

hardly any good-used for the F700/710/810 avail anywhere

another new (used) camera is my best advice - repairing a busted CCD aint worth your time / money / efforts.

Hello

The problem is that the lens has become stuck in the barrel after dropping it. There are some DIY solutions you could try, but the probability is that you will have to get it fixed by a professional.

Use these at own risk as it may further damage the camera.

Firstly , try connecting your ac adapter or usb cable.

Try holding the shutter button while switching on the camera.

Look at the lens , and if some of the lens 'circles' is misaligned or not concentric then try wiggling it (while holding camera lens down).

Try gently pushing or pulling the lens when it extends but this is risky as it may cause the lens barrel to slip out of its guidance system.

Another way to do this is to place the camera lens down on a hard surface and then power it up. Be sure to use a soft cloth or something similar as to not scratch your lens or casing. Let the lens push the camera up and down a few times and sometimes the little resistance provided by the camera is enough to get things going again.

Try hitting your camera near the lens on the body with the soft tissue on the palm of your hand.

Other than that , I would take the camera to a repair center for a evaluation to see if it would cost more to repair than to replace the camera.

If it is still under warranty I would suggest you take it in before trying any of these steps and remove any off-brand batteries or accessories as some stores are really fussy about warranty repairs on camera's with non-brand accessories.

Hope the advise is useful.

Are these pictures taken using the built-in flash and with the hood on the lens? If so, you're seeing the shadow of the lens hood.

Remove the lens hood when using the built-in flash.

The cap is a plastic disk, usually black or silver, that snaps on at the end of the lens to keep the lens clean. Some lenses have two caps, one for each end when not attached to the camera.
Some cameras don't use a "loose" cap; those cameras generally retract the lens into the camera body and "close" a door in front of the lens.
Many, if not most, camera users do not use a cap (my guess).

The wide angle lens is generally an "optional" lens that can be used for group or scenery pictures when you want to shoot a "wide" picture. A "normal" lens is generally around 50mm (plus / minus 5mm). A wide lens is anywhere from 17mm to 24mm (or so).

I recommend obtaining a wide lens... with a cap.

Hope this helps!

Hello,

It may be the equipment or it may be the way you are holding / taking the picture.

Here are suggestions on how to take better zoom lens pictures (this also applies to any camera) before you start diving into the equipment.

1) Use the fastest shutter speed possible. This reduces the amount of time of exposure, this limiting the amount of motion blur that can happen.
2) Don't hold the camera by hand. Either use a tri-pod or rest the camera on something stable, like a wall, rock, bench, etc. This makes it less likely that the camera will move when you are taking the picture, thus reducing motion blurr in the image.
3) If you have to hold the camera by hand, hold the zoom lens with your left hand (because it is more towards the center of gravity than the camera is) & try to slow your breathing & take the picture between heart beats.
4) Also, another thing that helps is to use a remote shutter release (such as that rubber bulb or plunger attached to the shutter release). I would also say using the self-timer would help, but the K1000 doesn't have that. This is so the camera doesn't shake from you pushing the shutter release button.
5) Make sure the lens is clean! Even get one of those lens pens from your local camera shop.

If you have tried all (or most of these) then its time to start looking at your equipment, such as . . . is your shutter getting stuck when exposing, thus lengthening the exposure and making for a blurring shot or do you need glasses? <grin -- which is why I find it really difficult to use manual focus equipement now, because my eye sight is really bad!>

Take care & Happy Imaging!
