SOURCE: I need to take sharp photos with my new 24-70mm,

There's an old rule of thumb which says, the maximum usable exposure time for hand held shots (without IS) approximately equals 1 / focal length.
So let's say for 50mm, you should try to use no longer exposure time than 1/50s.
Of course its possible to bend the rule a little, so with proper technique you can easily get a high percentage of good shots at 50mm and 1/30s. However, it's very unlikely that you will get a sharp image at, let's say 50mm and 1/15s.
Hope that helps...

My camera will take a photo in MF but not AF


And you are sure the AF MF switch on the lens is set to AF?
If so, check the contacts on the lens and in the camera. They should be clean and shiny and have on dent. Only clean with a dry cloth and cotton swab. Never use anything sharp in or close to a camera or lens.

Blurred image


A webcam is first and foremost a camera that uses a lens to gather light reflected by an object. There are a number of reasons why the image captured by the webcam can be blurry, all of which can be remedied.
Supplies from a photography store or hobby shop, along with items that most people already have in their homes, are needed.
The webcam does not need to be disassembled in any way in order to obtain a sharp and clear image.

Launch the webcam's video program by selecting it from the "Start," and the "All Applications" menu.
Aim the webcam towards you so that you can see the blurry image presented in the program's video window.
Rotate the knurled focus ring that surrounds the lens at the front of the webcam until the image is sharp; if there is no focus ring, position the webcam closer or farther from you until the video image is sharp.
Blow off the lens at the front of the webcam with compressed air.
Moisten the end of a cotton swab in photo lens cleaning solution.
Wipe the lens with the moistened end of the swab, beginning at the center and rotating in a circle until you reach the outer edge.
Wipe the lens dry with a lens tissue in the same manner as was just done, to remove the contaminants that caused the blurry image.
Launch the webcam video program that is on the hard drive.
Select the "Advanced" or "Options" tab at the top of the program's main window -- depending on how the program is set up to bring up a settings window.
Reset the "Sharpness" control to 65 percent of the total possible, using a slider control or entering "65" in a text field.
Click the "Apply" button at the bottom of the window, followed by the "OK" button to sharpen the image transmitted by the webcam.

My canon 18-55 lens will only take a picture in wide angle. as soon as i try to zoom at all it won't take a picture. it is 4 months old and hasn't been used much. and i haven't dropped it. any suggestions?


The Auto-Focus on the lens is damaged. I have had the exact same problem with my 18-55 and I ended up buying a new one because I take shots at weddings and I can't afford to manually focus each photo. You can still use it if you switch the small knob to MF and then use the focus ring for manual focus.

D70 photos not sharp - no matter which lens I use.


D70 produces lovely crisp images as long as the lens is pretty good.  This sounds like a camera body that needs a service.,,

Unsharp Images


My boss has the S-2. THis is the second one she has had. The first one would not give us a sharp image no matter what we did. We returned that body and got a new one.This one is better but to match the S-1 that I had at the time she had to turn the in camera sharpness on to high.I had the S-1 set to normal. I would check out what the in camera sharpness is set to. Is the camera new? Or is this a new problem. Fuji has good tech support you might want to give them a call. Best of luck
