Hi Russ,
I use my 70-200 for a lot of landscapes. This is the lens I have on my camera most the time. I find that you can pick out the part of the scene that you want to focus on.
Taking a landscape with a wide angle lens is harder than you think. The rectilinear distortion expands all the image content that is close to you. This means that you get a lot of foreground. If your foreground is boring then your image is going to look boring too.
Ways to solve this is include:
- Not having a foreground, e.g. shooting off a balcony
- Having a good foreground, e.g. an object of interest like a statue
- Using a telephoto lens to skip the foreground
In the case where the lens is not quite wide enough then you can do a panarama stitch. Here is an example of 2 images taken with a crop camera at 70mm:
A good way to see what a longer lens can do for landscapes is to browse images that have the EXIF data present. That way you get to see the lens used to take the picture.
The best of both worlds is to carry lenses that cover more focal lengths. You can then swap between them. However if you only have one lens then remember that the best lens is the one you have with you.
Regards,
Alex
