Which one to choose
Choose the Fujinon XF8mmF3.5 R WR if
- you want more in the frame. It starts at 12 mm equivalent, against 17 mm on the other lens — interiors, landscapes and groups at close range.
Choose the Tamron 11-20mm F2.8 Di III-A RXD if
- low light is the priority. At f/2.8 it lets in 0.6 stops more than f/3.5 — faster shutter speeds indoors and softer backgrounds.
- your subject is far away. It magnifies 2.5× more, and walking closer is not always an option.
Everything above comes from published specifications. How sharp each lens is, how quickly it focuses and what its pictures look like are not in any spec sheet, so this comparison does not try to judge them.
