View Full Version : Dim corner by my XA
I have a XA and XA4, both nice camera and I use them often.
However, I found that the photos are a bit dim at corners, like the attached.
Hallo Conrad :) That dimming is called optical vignetting and is caused by the lens design. This will explain it much better than I could - http://en.wikipedia.org/wiki/Vignetting
Cheers, Ian :)
After reading, optical vignetting could be reduced by stop down the aperture. Does it mean that I should use slow aperture to avoid vignetting?
Hi Conrad. I am no expert, but I believe that using a smaller aperture will reduce vignetting :)
Cheers, Ian :)
Thanks Ian. Sorry for mixed up your name.
The XA is known to have light fall off (not exactly the same as vignetting), but it the effect varies from sample to sample of the XA.
The sample you posted, Ian, also have some natural falloff due to the angle of the sun with respect to the blue of the sky.
I find the XA's falloff to be quite pleasant in many shots ... adds some depth. YMMV.
Thanks a lot again
True, I also noticed the noticable fallof a while ago, but it wasn't disturbing the picture. Note that I have the XA2, which has a different lens, but I can imagine that the very compact design of all XA's must have some drawbacks...
Conrad, the vignetting effect is one of the many charms of the XA.
I happen to like it a lot because it draws you into the center spot, where your subject usually is.
You should use it to your advantage :)
Agree, I will try to use it as an advantage
