I just picked up a well used 70d, she seems fully functional etc, but I was looking at a 30s exposed pic with the lens cap on, and I found a whole galaxy. Should I be worried??
edit: image size a bit small, each orange circle contains a small thing as in the fullsize picture. They come in red...
Dear photographers,
I have used a 350d for the past 10 years but recently I have been noticing that the autofocus isn't doing great. I use the center point focus, but it seems to be off randomly, especially in low light. Lens is a Canon EFS 17-55 2.8 and I was afraid that it might be off...
SHORT STORY :)
What are the general thoughts on the comparison of:
Sigma 18-50 f/2.8
Tamron 17-50 f/2.8
Canon 17-55 f/2.8 IS
And between that and a body upgrade (350d --> 30d / 40d), what would you prefer? (complete current kit below, for comparison)
Thanks! :)
