In order to find out what's next for me, lens wise, I've been going back through photos and seeing what focal length I typically use, given my existing lenses cover 18 - 250mm. On a Fall trip to NYC, the winner was the 50mm f 1.4 (which is fortunately EF not EF-S so still works on the full frame). However, I did make use of the full zoom of my EF-S 55-250mm. Lens search: to be continued...
First, caught in a downpour in the Garment District, with the 50mm:
Then, more building pictures using the full 250mm zoom of the EF-S 55-250mm lens. (My poor man's Michael Wolf impression).
And back with the 50mm... my hostess and dear friend's cat, Harlow. An East Village Himalayan.
