Question about Canon PowerShot A620 Digital Camera

1 Answer

Image reduced by dark edges

When using just the A620 camera, the image is fine. When adding the adapter and a lens, the image is reduced by dark edges. The same image is shown on the LCD screen. Wide angle lens image has a fuzzy dark ring around the outer edge. Telephoto lens usually has a fuzzy dark triangle in the lower right corner. What can be seen of the picture is not distorted.

Any assistance would be appreciated.

An adapter tube has to flare out at the end or it will cut the corners off at the wide angle setting. Telephoto should be ok though.

Canon a620. no image on display and pictures turn out black


A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, sometimes with lines, especially when taken outdoors (for shutter stuck open). To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.

I have Cannon A-1 and F-1 Camera bodies, plus all Cannon FD lens. Can I buy a new Cannon digital camera and use a special adapter and use those older FD lens. I would appreciate any reasonable input. JD


No. The only adapters you can get either lose infinity focus or need corrective optics (expensive and reduce image quality) to preserve infinity focussing. The lenses will need to be manually stopped down for metering purposes and the body will only be able to use manual and aperture priority modes.

Also, with modern computer designed optics, using FD lenses on a modern digital SLR is like screwing an old glass bottle on the front and hoping to get sharp images. An exaggeration, perhaps, but you will get significant edge softness and chromatic aberrations and the contrast will be lower than acceptable and truly dreadful with optically corrected adapters.

Canon A620 is taking black images/ Can't see images on screen


First try pressing the DISP or DISPLAY button on the back of your camera. If that didn't fix it... A stuck shutter is another common failure mode for digital cameras.

The camera is developing dark areas around the edge of the pictures on 2 different sides. you can see these dark spots on the viewfinder and on the pictures. what is causing this?


If your lens is clean.

The dark spots maybe your image pickup sensor going out. Try going into the menu to tools select pixel mapping see if that helps it will look at all your pixels and determine if they are bad & try to compensate.

Hope it helps. Good Luck! please let me Know if this works or if you need more help.

My d40 has a image in viewfinder, will not take picture


It sounds to me that you are using an incompatible lens or a broken one. Does this happen with the lens that came with the camera?

I am trying to get clear closeups of teeth (work in a dental office!) and I keep getting blurry pics. We do have a telephoto lens but I have no idea how to use it... Help?!


For the best photos of close-up it is recommended to use a tripod since the Canon A620 has no image stabilization. You can then use the macro setting and set if for the distance you will be shooting from and your photos will be a great clearer and with no blur

Conversion lenses & filters


These screw on the front of the plastic lens adapter and adjust the focal length. On the side of the adapter lenses it will quote the ratio. My wide angle says 0.66x so just multiply the range of focal lengths by this figure and you will see that it adjusts the camera zoom accordingly - making the image wider and probably also increasing the depth of field (what is in focus). Similarly a 1.5 tele will inrease the range of focal lengths to make the lens "longer" eg higher magnification , useful for astro photography - shots of the moon and terrestrial long distance work but detracting from the depth of field, eg the range of distance over which objects are in focus will be reduced.

The wide angle will allow you to come in close and get WIDE objects fully in-frame- hence "wide angle", while the telephoto will give you better overall maginification of the image but will probably increase the MINIMUM focal length - eg you may not be able to focus on objects closer than >2m (instead of ~1).

The screw-on adapter lenses I found were cheap in a Jessops sale use a 52mm thread, while the S5500 provides a 55mm internal thread. I use an appropriate 55mm to 52mm step down ring adapter. There is slight vignetting (shading around the edge of an image) at certain combinations of zoom, but generally these are very useful accessories.

As these are adapter lenses on the front of an already powerful 10x zoom that must be optically compromised at the price of this camera, there maybe some colour fringeing around bright images. If you want a better solution you really need to get a DSLR. Overall a good solution for the price.

Difference between flash image on camera screen and PC


martod,
Every picture looks good on the LCD since it's small, make sure you set your camera to flash, try ISO 200 and if the flash is TTL (thru the Lens) for digital it should adjust to the shot based on your other settings - I'm not familiar with that flash.

Uneven flash


Look carefully at your images taken with flash... on the horizontal image is the lower part of the image slighty darker and have a rounded fall off at the edges? Is the vertical image dark side a straight hard line or is there a rounding to the top and bottom?

What we are looking at is if you have a very wide angle lens with the lens shade attached to the lens, then the built-in flash catches part of the lens shade and make a shadow on your subject... take the lens shade off and try the same shot and see if that makes a difference...

Have a great day...

How to increase brightness in Canon Powersot A620 ?


Are you asking about brightness as viewed on the LCD, or are you asking about increasing brightness on the actual image taken? If it's the image, there are two special modes that you can select on your mode dial. They are "Night Scene", "Night Snaphot", and "Indoor". A description of both, along with your camera's other special settings, may be found here:

http://www.canon.co.jp/imaging/mode/camera/scene-e.html

"Night Scene" can be selected directly from the dial. It's the one showing a person standing under a star. Note that Night Scene should be used with a tripod to reduce the potential for blurriness.

"Night Snapshot" works almost as well, but does not require a tripod. It can be accessed by selecting SCN on the dial, and then pressing right or left with the selection buttons until it shows in the menu. The camera will remember this setting the next time you select SCN. I usually keep my camera always set to this setting so that I merely have to select SCN to use it.

"Indoor" works very well in those large rooms that may produce dark backgrounds when taking photos. It also does not require a tripod. It's accessed the same way as "Night Snapshot" (Select SCN, then right/left until selected). This is another good setting that I like to keep sometimes set in SCN.

Try all three settings, (and don't forget all the others too). Think you'll be impressed.
