Hi,
I've attached a photo with strange distortion of the horizon at the top of the image.
The photo was taken on a K5 with 18-135 lens at 40mm F7.1 1/800 ISO100
Any comments or opinions will be helpful.
Is this normal? I thought that at 40mm which is 60mm on 35mm format gives you a perfectly flat horizon and on this photo it is bending the wrong way. The curve should bend the other way if my math is correct!
Cheers
Frank.
