My first SLR was the Canon EOS 550D at the age of 14. I bought it with my first money I earned at a summer job as a waiter in a small hut in the mountains.
Since then, I have always dreamed of the L-lenses and full frame, but could never afford them. I always wanted to buy an ef-s wide angle lens, but never did, because I knew that one day I would buy a full frame camera and then I could not use the ef-s lenses anymore. (I have regretted that I don't have a wide-angle zoom on too many occasions :/ ) Now, 10 years later, I have bought a used 5D mark IV (I will enjoy it for many more years before I buy a used R5 mark II or III, at least that is my plan)
Here is my question: I would like to buy one of the L wide angle lenses, for landscape photography, architecture and occasional travel and rarely for events. Which ones offer the best value for money? Is the 3rd generation of the 16-35 2.8 worth it? It still costs twice as much as the II or the 4.0 versions in the used market. Which would you recommend the 2.8 or 4.0 version in terms of image quality? Is the 11-24mm an option for the above mentioned applications? I would also be interested in the EF 24mm TSE lens for architectural photography and depth-of-field games. Is the version II worth the extra price? Can any of you share any experiences with that lenses?
