I-Pointment

8mm offers us a lot of room around our motives, as you can see.
I like to use my wide angle lenses mainly for two reasons:
1. For showing classical landscapes and using the lens everywhere, where i have not very much space, f.i. in small rooms. And
2. as a tool for extreme compositions, as a kind of creative "fun" lense.
It is a lot of fun, to put different image elements together and play with perspective and space.
I also must say, that a very good wide angle lens without distortion is not always the best lens for such "games". For instance the 8-16 Sigma is almost a kind of "corrected fisheye" and maybe not the first choice for classical "serious" landscapes, where f.i. a 10-24 or 12-24 Nikkor is probable better. But when it comes to creativity and biggest possible image effect, the extreme lenses are more interesting in my eyes.
This is the reason, that i recommend landscape photographers 2 or even 3 extreme lenses: One for classical landscapes, one for creative landscapes - and maybe an additional fisheye for "extreme fun". :-)
