01 Sep 08 Zoom creep

1. A problem often suffered by push-pull zoom lenses. Such lenses have their focal length
settings held in place by friction, and sometimes this isn’t enough to counteract the weight of
the lens.
If you have a lens which slowly slides, changing focal length, when it’s pointing up or down
then you have a lens which exhibits zoom creep. Two-touch zoom lenses usually do not suffer
from this problem to the same extent. Some lenses have locking friction rings to help deal
with the problem.

@whoisariston That is a great combo. But what about wide angle? #
@tellute Panasonic makes a sharp camera with quick responce. And with the mega OIS & Ai and 10x Optical. Good choice!! #
@whoisariston Sounds great. Good luck with it! The D300 is a marvelous creature! #

@jefferson08 What kind are you looking for? #
@_krees What camera and repair? #
@_krees What kind of camera? #
@_krees Unfortunatly a Sony main board is quite expensive. Try to find the sales receipt or call the store you purchased it from for a dupe #
@barbaravey What kind of camera did you lose? #
@_krees Sounds like either a Main Board, Power Board or battery connection problem. No impacts on lens I presume? Sony brand battery? #
@madbob What kind are you looking for? Maybe I can help get you started in the right direction #
@_krees Then most likely a board. I suggest trying to get a dupe receipt from the dealer rather then spending so much money. #
@RoadtripUSA What camera did you get? #
@nrayko We give estimates on fixing cameras. Send it our way #
@t94xr Check for smudges on the lens. #
@aidanisamoron Sand is difficult . usually salty air with it. The sand will be sticky and most likely cause corrosion if not removed #
@_krees They are pretty large company. Most likely yes!! #
@_krees That’s all preference really. Canon vs Nikon is physical feel in hands & menu navigation. Choosing exact model is on what… #
@_krees What your future may bring. The D40 & D60 can only use certain Nikon lenses. In the future that may not be good for you. #

30 Jul 08 Out of Focus or Blurry Images

Out of Focus or Blurry Images

Blurry images may be caused when there isn’t enough light for the camera to set a fast shutter speed. The camera’s shutter opens and has to stay open for up to several seconds for enough light to hit the CCD to capture the image. Most people cannot hold a camera perfectly still for more then ¹/_60th of a second.

In addition, when the telephoto feature is used on a long zoom camera, the field of view becomes smaller. Since a lens with a large focal length provides a small picture area, even slight imperceptible camera movement will cause a blurred picture.

To help eliminate out of focus or blurry images, try one or more of the following when applicable:

· If inside use the flash.

· Change to a fast shutter speed.

· Put the camera on a flat surface or use a tripod.

· Brace yourself against a tree or wall.

· Put the camera in sports mode.

· For situations with low light, raise the ISO. (Please note this will impede image quality)
