Vignetting problem in Powershot A80!?

[cheewooi]

Please take a look on the photos posted! Notice that tem! Thhere's vignetting problem with Powershot A80 when taking shot in wide angle! I knew this problem is not new, and lot's of Powershot A80 user encounter this problere's nothing can be do to the lens but to bear with it! What I do is try not to take photo with wide angle, but zoom in a step and the vignetting problem is resolved! You may want to save the setting to C1 o r C2 in A80! Just a precaution when taking shot!

Here's some wide angle shot taken with my A80! Please note that there is no lense adapter nor wideangle or any accesories lens attached to this camera! All based on Canon lens in A80!

Is that a Hello Kitty bed set...? o.o

Were you using the flash in those tests? If so, it might be that the flash isn't quite powerful enough to illuminate the corners of the photos. Just a thought.

Disclaimer:
I have an A80 and haven't noticed any vignetting, but I haven't tested it and don't normally shoot against a white background like that.

Hi,

I must agree with Syldorian, the A80 shouldn't suffer from this problem "out of the box". With the wide-angle lens you do, and its a lot more pronounced than you illustrate here.

I would try doing some test shots in different lighting conditions to see if this was just a fluke.

I just shot this about 6inchs away from the wall with full flash.

I pulled out the tripod and shot this with a 2.5s time exposure, no flash!

Its quite clear the flash is causeing most of the trouble and would explain why it dosn't effect most photos. The flash IMO is only really any good for snap shots. Altough with lots of practice setting it to lower intensity it can be made to work ok, but thats a differnt topic.


However its not something I ever noticed before, its certianly never effected any of my photos.
While its clearly there it only appears to show up on very white back grounds.
If your going to be doing some product photography it could be an issue, but as mentioned its easy to zoom in slightly and get rid of it.


I also think the examples at the start of thread over exagerate the problem, as mentioned its either largley due to the shooting environment, or its just a one off bad lens. (or I got a one off good lens).

How to set it to lower intensity?

Regarding the flash fall off issue, can we use slave flash to overcome this problem? Cause I did a lots of indoor shot and I notice that A80 flash is not powerful enough to illuminate the scene.. :cry:

In manaul mode "M" press function and the first menu lets you select the flash intensity.

It isn't the worlds greatest flash, but there a lot worse and it is only a small point and shoot camera.
Unforunatly there is no hot shoe for a remote flash, for that you need a G series.

My wide angle shots vignette a little too. The wide angle lens sees the edges of your wide angle auxillary lens. My vignetting is far blacker than that though. I just shrug and crop or clone it out.

Are you talking about the wideangle lens, WC-DC52 ?

I just ordered this, and your post makes me sad

[Don Schaeffer]

No i'm not. I had an old .6x lens from a Kowa SLR I bought many years ago. The vignetting is ok I can live with it anway.
