As a first thread and an introduction a few shots which from I would like some comments.. I've been shooting with 550d and 18-55 kit lens for few months and finding it very hard to obtain any sharpness on landscapes. I know it is a feature with this lens and have come to a conclusion that at least a wider aperture serves better than a narrow one. Any other hints with this? I'll be getting a new lens (most likely sigma 17-70 2.8-4 IS) but in the mean time... 1. 2. 3. 4.
