Vignetting - and how to avoid it

[akerosid]

I have been having quite a few photos rejected recently because of vignetting. I had been advised in the past that if I had the camera set to "A" (aperture priority), this would correct it, but it's happening again and again; I have also applied the lens correction to correct for vignetting, but it doesn't seem to have much effect.

Can someone please advise, definitively, what can be done to avoid this.

Hello,
this is mostly happen on very low apertures or very high. Try to shoot around f7.1 - f8. In sunny day it will give an average speed of 1/500 - 1/640 which is enough to get sharp photo.
Also my advice is to always shoot in RAW. It will give you much more options in post processing. Enable Profile Correction will not have any effect if you shoot jpeg.

Vignetting typically occurs when shooting with a wider aperture. The more you close down the aperture, the less you should notice it. It's also much more of a factor for full-frame cameras, so if you are using a crop-frame, it should be easy to avoid by stopping down the aperture. Simply putting the camera in 'A' setting will do nothing to improve things unless you then choose an appropriate aperture. Simply choosing 'A' mode and hoping that will solve the issue is akin to wanting to watch the football game and simply turning on the TV without then selecting the proper channel.

Thank you both for your responses.

I'm going to ask what might come across as a very basic question, that I should have known long ago, but here goes!

My lens is a 28-300mm, F3.5 to 5.6. So, if - as you're suggesting, I go above that, does it actually have any effect, or does the camera's settings take precedence? Most lenses do seem to be around that mark (and a lot are lower than that, so I'm wondering if setting it to 7.1 or 8, will override that 5.6 limit?)

Many thanks.

I guess you could say I don't know my "A" from my elbow ...

The noticed values are the maximum wide aperture your lens is capable. That`s mean that if you at 28mm you are able to shoot at minimum of f3.5 and if you shot 300mm the minimum aperture is f5.6. I think your range for 28mm is around f3.5-f22 so all you need to do is to select the Aperture Priority mode on your camera put the aperture on f7.1 or f8 and start shooting.

I suffer from Vingnetting quite alot as I shoot with a full frame camera, but shooting raw and using the correction in Adobe Camera Raw works pretty well for me.
