Question about Canon PowerShot A75 Digital Camera

1 Answer

Out of focus viewfinder, zoom problems

I have had an A75 for about two months. It's worked generally well until today. It seemed to stop shooting while out on a shoot (I was also using an SLR with tripod as the main camera). The lens won't retract all the way and close. The viewfinder is out of focus in the wide mode. When you zoom in, it's sharper. The zoom lens control - it will zoom in but then it sticks and won't let you return to wide. The shots it take are blurry as well. I was taking photos in cold weather, so that may have been a factor. But hours later it still is having problems. I don't recall dropping the camera. I did have it in a coat pocket next to some keys, but can't see how it may have gotten damaged. The warranty is for one year. I'm considering taking it back to the Office Depot or Office Max and requesting a replacement. Should I call Canon first to see what the problem is? What could be the problem?

Re: out of focus viewfinder, zoom problems

1. Stop shooting while out on a shoot: Perhaps the batteries were running low? 2. Lens won't retract all the way and close: Could be same reason as #1.? 3. Viewfinder is out of focus in wide mode: Could it be that camera was left in "Macro Mode" (Flower icon)? Did you set, "Custom Function 1, or 2," and accidentally set the unintended exposure mode? 4. Sticks in telephoto, won't return to wide, blurry shots: Probably cold weather related? Perhaps, "reboot" the camera by removing all batteries for over 10-15 seconds, and replace with a freshly recharged set of NIMH batteries? If all of the above failed, then I'd say take it back to where you purchased it, and get a replacement unit. Good luck. ^_^

Canon 1d mark 4 camera viewfinder problem


Adjust the viewfinder diopter to match your eye. Remove the rubber eyecup by grasping both sides and sliding it up. Turn the little knob to the left of the viewfinder until the focus points or center metering circle appear sharp. Replace the eyecup.

Shutter release not responding


Hi tmclaughlin0, In the camera is in AF-S mode, the camera will not shoot until it acquires focus. Look on page 29 of the D80 manual.

Appears in focus in viewfinder, but isn't


Change your focusing setting to spot focus. Then, focus on your main subject, keep the button half-way pressed while you re-compose the shot and then press it the rest of the way. Does that improve the shot?

Canon S5 IS. I am having problems with Macro shooting. As I look through view finder, object seems in focus, but when I press focus lock button (halfway) the image jumps out of focus.


Dear Stefan:

Barring a malfunction with your len's autofocusing mechanism, the problem that you're experiencing is likely due to the limitations of the camera's focusing / zoom range in Macro mode.

You didn't say what ranges you were shooting from but basically, in order to get proper focus, you must first make sure you're within the proper lens to subject distance for the macro mode that you've chosen.

There are two macro modeson the S5, Macro and Super Macro. Macro shooting is done only within the ranges of 3.9 inches to 1.6 feet from your subject. SuperMacro mode (which is entered into by simply pressing the Macro button for one second) will only focus within the ranges of 0 inches to 3.9 inches. So if you are in either of these modes and stray from their focusing ranges, your camera won't focus properly.

Another issue that you may be dealing with is the very limited zoom range in Macro/Super Macro Modes. The zoom is basically meant to be set toward the maximum wide angle end of the zoom range. There is a yellow indicator bar below the Zoom Bar in the viewfinder that indicates the Out-Of-Zoom range in which the zoom basically can't be used. As you may see, only the first 10% or so of the zoom range is useable.

It might be that you could possibly be wavering in and out of the two macro mode focusing ranges and/or zooming into the Out-Of-Range zone during your session. Either can cause a similar effect such as you are describing. It's hard to say without actually being there.

To test this out I would simply set my camera on a tripod or other stand at a known fixed distance from the subject, set the camera to the macro mode indicated by that distance (either MACRO or SUPERMACRO), zoom out to the widest focal length and take the shot to see if it is clear or not.

If so, your camera probably has no problem. If it is still not focusing properly you might want to send it into the service center for a diagnostic. There is no charge to diagnose a problem with your camera and if nothing is found to be wrong you will only be out of the shipping charges spent to send the camera in to the service center. If a repair is needed, it can be done at that time.

Hope this helps you.

Sincerely,
HeavyDLB

Nikon D40X stopped auto-focusing yesterday


I had the same problem. My issue was with all my lenses. I solved it by going to the menu and selecting the custom setting menu (pencil icon). Then from the right menu select the AE-L/AF-L and press OK. Then make sure it is set on AE/AF Lock. Presto...all my lenses worked on auto-focus.

Optical viewfinder zoom isn't working


no ideas on how you can get it working. There is I should think a connection adrift. Try the Konica Tech Support Team But be prepared for a zilch answer- I don't think a 'repair' will come into the equation

Focus Problem


I have the C740, which I believe works very similarly if not identically. Unless you have the camera in full time auto focus, I don't believe it actually focuses on the subject until you've pressed the shutter button half way. Until then, the subject may look in focus in the viewfinder, but is not. When you fully depress the shutter in one motion (rather than pressing half way first), the camera will attempt to focus before it takes the shot. If you are not careful about camera movement, you may inadvertently be focusing on something other than what you intended. My camera (and it seems all digicams) has trouble focusing in low light, so you definitely want to use the half press in such situations. Even then, I don't always get the focus correct. Thank the digital Gods for instant feedback! Personally, I almost always use the half press method. To get the 740 in manual focus, you hold the "OK" button down until you see the viewfinder display a focusing scale. It takes a second or so. You should also see "MF" and "AF" designations in the lower left corner of the viewfinder when the scale displays. Use the left and right arrows to select the focus mode you want (i.e. MF or AF), then use the up and down arrows to adjust the focus distance. You'll notice that the area you are focusing on is enlarged when you use the up and down arrows.
