I own a Sony a6500 camera and I bought one lens Sony 18-105mm f4.
I plan a trip to Iceland and I would to make some good landscape photos.
I saw the first season of "Photographing the World" where they take pictures there with full frame camera and they show the differences between taking pics with 16-24mm.
I started to think that my 18mm (which equivalent to 24mm+) wont capture what I wanted.
I thought to get a new more wider lens for it where the options are:
1) Sigma 16mm f1.4
2) Sony 10-18mm f4
Now im not sure what should I get since I dont think the differences from 16mm in the sigma to my 18mm is that big but maybe the low f number will add some effects while the sony offers wider lens but little worried it will be dark.
I also heard about an option of using Sony 16mm f2.8 and using adapter to 12mm.
