My most used lens is the Fujifilm XF23mmF1.4. While its not a typical landscape lens it works fabulously for panoramic shots like this one. This a crop from 6 vertical panorama shots using an Fujifilm X-T1, XF23mmF1.4. Each shot was 20 seconds at ISO 200, f10. Again I just left work and looked up and literally ran down to the boat ramp with a camera and tripod in hand. Always be prepared! I will always start at ISO 200, f8-11 and adjust shutter speed as required. Some of my favourite images have been just before or just after the sun is up, and love long exposures.
