Hi all fellow clubsnappers, last week I was at marina barrage. The moon was round and beautiful, so I set up my tripod and start taking pictures of the moon. But I encounter a problem that I could not solve. I was using a 500D with a EF 85mm 1.8 lens when taking the moon picture. I am aware of the 1.6 ratio, therefore I was able to reach 135mm at 1.8. When focusing on the subject(moon) I could actually see the surface of the moon clear, but when I click the shutter, the picture came out totally different. Is there a way to counter it??
