Tilt shift on an ultra wide 17mm lens can either make your buildings look natural and solid or turn them into distorted shapes that feel wrong. When you shoot architecture, interiors, or tight city streets, understanding exactly how that movement works at this focal length decides whether your images look intentional or like corrections gone too far.
Coming to you from Keith Cooper, this detailed video walks through the TTArtisan 17mm f/4 Tilt-Shift lens as something you might actually rely on, not just experiment with once. Cooper focuses on the G-mount version for Fujifilm medium format, where you get +/- 8 mm of shift but no ability to rotate the lens on the mount. In landscape orientation, that means rise and fall only; flip to portrait and your shift becomes left and right, which feels fine for basic vertical corrections but cuts off some of the more creative movements you might expect from a tilt shift. He points out that on such a wide angle, most real use is rise and fall to keep verticals straight, with tilt coming in only for specific tasks. You see the tradeoff clearly: a solidly built all-metal lens with useful movements, but with a fixed shift axis that you need to accept up front. If you have been dreaming about diagonal shift or more complex movement combinations, this is where you start questioning whether the price savings justify the compromise.
Cooper spends time on the crucial stuff: brick walls, vignetting, and distortion. Wide open at f/4, you see some falloff and a mild, even barrel distortion that is visible on flat subjects but easy to correct manually. Stop down and the corners tighten up, with f/5.6 and f/8 giving the best balance between sharpness and depth of field, especially when you add shift. Because the lens has no electronics, your camera does not know which lens is attached, and there is no EXIF data for shift amount, so you set focal length manually for stabilization and handle all corrections yourself. The video shows how manageable that is on modern bodies, including plenty of handheld shots where Cooper uses in-body stabilization and still gets crisp detail. You also see flare behavior, sun stars from the 10-blade aperture, and what happens when a streetlight or the sun hits that protruding front element. If you care about how a lens behaves in real light rather than on a spec sheet, those tests carry more weight than any MTF chart.

Where the video gets especially useful is when Cooper compares this lens with the long-standing Canon TS-E 17mm f/4L Tilt-Shift Lens. You see how the TTArtisan holds its own in sharpness, especially in the corners. He shows how much practical difference there is between 8 mm of shift on the TTArtisan and 12 mm on the Canon, and it turns out that at this focal length the extra shift is less dramatic than you might expect. Cooper also talks about using the lens purely as a 17mm wide angle on medium format, where the large image circle and clean detail make it attractive even when you are not shifting at all. For anyone balancing the cost of repairing or replacing older tilt shift glass against buying something newer and cheaper, seeing those side-by-side examples is valuable. He hints at where a more advanced option like the Fujifilm GF 30mm f/5.6 T/S Macro Lens still wins, especially in flexibility and electronic integration.
Cooper also touches on the mirrorless versions of the TTArtisan design, which add mount rotation on systems like Canon RF, Nikon Z, and Sony E, turning the lens into a more direct competitor to both Canon’s tilt shift lineup and Fujifilm’s own T/S options. If you are using something like a Canon EOS R5, the idea of getting a rotating 17mm tilt shift that does not cost as much as the native Canon lens is going to catch your attention. The video does not just talk about movements in the abstract; you see how small changes in camera position and shift affect compositions on real streets, with real converging lines and awkward foregrounds. Cooper shows tilt in use as well, including examples where he runs the focus plane along a wall or across a scene, and you see both the strengths and the limits of tilt at 17mm. There is also a useful look at how to avoid and control flare in night scenes and how much you can push files in post when you start from a 100 MP sensor and a sharp lens. Those practical demonstrations are hard to translate into text because the nuance sits in tiny changes between frames that you only appreciate on screen, so check out the video above for the full rundown from Cooper.
