Thanks for the previous help with body or lens. I will stay with the Canon 1000D and go for a lens for landscape.
I was looking at a few sigma lenses, the 8-16, the 10-20 f3.5 and 10-20 f4-5.6.
The wider angle of the 8-16 interests me, but having no ability to attach a filter worries me a little.
Doing some searching the main differences 10-20 f3.5 and 10-20 f4-5.6 I can see is the 3.5 is a little faster and $150 to $200 more expensive.
Can anyone recommend one of these over the other, or is another a better investment?
