<p>hi everybody,<br> I have Canon 7d and I use it for wildlife photography with 300mm,f/2.8, Now I wish to try my hand in 'Landscapes'. Do I go for lens like C 10-22 and use it with 7d or it is essential to go for a full-frame camera and lens like 17-40? The most amazing landscapes I have seen are done with full-frame camera. Thanks !</p>
