Re: blurring/grainy pictures, and lens error


here are some tips that may be the reason why you are having those blurry, grainy and yellowish pics.

It is important to keep your lens away from excessive heat (i.e., hot car in summertime or a heat source in a home). This will help prevent the greases, used in most lens barrels, from breaking down into an oil that can run inside your lens and cause overexposure by slowing down the diaphragm.

Use rear element lens caps on your lenses when they are not on the body. Wide angle lenses, by design, have rear elements that extend out farther then the lens barrel and are susceptible to wear, which can ruin sharpness.

Always use a filter or lens shade (hood) to protect the front element.

Never, ever, oil your lens. A minute amount of oil on the diaphragm blades will cause them to operate slowly.

hope this helps

Memory cards don't cause blurry pics. Is your lens clean? Is the lens extending properly?

The night setting results in blurry pictures

The grain is from underxexposure and the blur is from hand shake caused by low shutter speed. Try using a tripod. Also, change from auto settings and shoot in manual mode with a high ISO and low aperture setting. Good luck!

Grainy pictures

I have had this on my camera,

I took it apart and cleaned all the lens from behind and it took perfect pictures.

You best bet is to google the service manual, and see were you can go from there. if not take it to a local repair store.

Hope this helps.

Blurred pictures

If it's from moisture then once that dries out it will clear up. Otherwise if it doesn't then you will have to send it into repairs and they can clean the internal lens for you.

Blurred Pictures

1. What is the focal length of lens you are using? 2. Is the blur occurring with lens with a lower focal length than the telelens? 3. Do you still get a blur when you use the telelens with a tripod or a firm base? Regards Raman

Blurry pictures with Pentax K1000


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!

Blurry/grainy image in viewfinder and resulting pictures

This is not going to get repaired at a sensible price. Check out Kodak Technical support but I think you are looking at replacing the camera
