LAOWA 15mm f4,5R Zero-D Shift Canon RF

The shift mechanism is precise and smooth, making architectural shots much easier to compose. I love how well it corrects distortion even at the extreme edges of the frame.

The 110-degree field of view is just wild—I can finally frame a whole cathedral nave without stitching. Shift movements glide smoothly, and the zero-distortion is freakishly good for an ultrawide. Coupled with the R5 II, it's my go-to for architectural work now.

Took this out for an interior shoot and the vertical lines stayed perfectly straight, which saved me a ton of time in post. The 15mm shift on full frame is wider than I expected, though you definitely need to watch your feet in the frame.
