When I got into photography in 2008, as far as I was concerned swa lenses were the best choice for landscape photography. I used a Canon 10-22 and I was happy with the results. I've had a break from photography and got back into it this year so I bought a Canon 10-18 as I thought I would use it quite a lot on holiday. I also bought a Canon 70-300L IS to use as a walkabout lens (although I may regret not bring the 100-400 as we will be doing a trip for wildlife). On a recent excursion I got fed up with changing lenses so I decided to use just the 70-300. So far as I've only been able to see my images on my phones display but it looks like I'm going to more be than happy with the results. One reason I decided to try this is because another member here (long lens photography) advocates using long lenses for landscapes. I've previously used other shorter zoom lenses for landscapes but the idea of using a longer zooms had never previously entered my mind. This has made me realise I can get the results I want with one lens rather than taking another one on holiday and faffing about changing lenses. I'm now toying with selling the 10 -18 as I don't think I'll use again. Perhaps this time around I've been more open minded than I was 10 years ago.
