These are the best Tamron lenses for landscape photography when you want rectilinear lines, crisp corners, disciplined flare, and rich micro-contrast for mountains, coasts, forests, and deserts—and here’s what to look for as you buy: prioritize ultra-wide to short-tele coverage with low native distortion and strong edge performance at ƒ5.6–ƒ11, coatings that suppress veiling/ghosting around sunstars, even field curvature, close-focus for foreground drama, and light, weather-resistant barrels that hike well; minimal focus breathing helps if you film, internal focus is nicer on gimbals, and shared filter threads (often 67 mm) let one CPL (use gently to avoid blotchy skies) and a small ND kit cover the set. Full-frame prime/compact heroes: 20mm ƒ2.8 Di III OSD M1:2 and 24mm ƒ2.8 Di III OSD M1:2 (tiny, sharp, half-macro for textures and flowers), and 35mm ƒ2.8 Di III OSD M1:2 (everyday “normal” with 1:2 close-focus for detail frames). Ultra-wide and standard zoom workhorses: 17–28mm ƒ2.8 Di III RXD (featherweight breadth with crisp corners—great flare control and a gimbal darling), 20–40mm ƒ2.8 Di III VXD (walk-and-talk range that doubles as a vista tool; excellent close-focus for lead-in elements), 17–50mm ƒ4 Di III VXD (constant ƒ4 with tidy handling for hybrid stills/video and Super35 crops), and 28–75mm ƒ2.8 Di III VXD G2 (prime-like sharpness, stellar close-focus for flora/rocks; pairs perfectly after an ultra-wide); for tele compression of ridgelines and distant layers, 70–180mm ƒ2.8 Di III VC VXD G2 (light, stabilized) or the value 70–180mm ƒ2.8 VXD, plus 50–400mm ƒ4.5–6.3 VC VXD (surprisingly sharp, goes wide enough for context, 0.5× at 50 mm for macro-ish details) and 150–500mm ƒ5–6.7 VC VXD (packable reach for abstract peaks and wildlife along the trail). Legacy/adaptable classics for DSLR mounts: 15–30mm ƒ2.8 (VC versions where available) for fast UWA breadth and robust flare control, 24–70mm ƒ2.8 G2 VC as a stabilized mid-range anchor, and 70–200mm ƒ2.8 G2 VC for compressed landscapes and stitched panos. APS-C hikers get standout kits with 11–20mm ƒ2.8 Di III-A RXD (bright, tiny UWA for tight canyons and astro), 17–70mm ƒ2.8 Di III-A VC RXD (stabilized do-it-all with strong wide-end sharpness and close-focus), and 18–300mm ƒ3.5–6.3 Di III-A VC VXD (one-lens travel solution); full-frame 17–28/2.8, 20–40/2.8, 28–75/2.8, and 70–180/2.8 also shine on crop for bonus “reach.” Practical buyer tips: build a two-zoom spine (17–28/2.8 + 28–75/2.8 G2 for speed, or 17–50/4 + 20–40/2.8 for hybrid video) and add a light tele (70–180/2.8 G2 or 50–400) for compression; standardize to 67 mm with step-up rings so one CPL and a 3/6/10-stop ND set fit everything; test lenses for mustache distortion, field curvature, and flare before big trips; lighter glass means longer miles and steadier holds in wind. Landscape shooting tips: time golden/blue hour to balance sky and land, level horizons and leave margin for post, work at ƒ5.6–ƒ8 for maximum plane sharpness (push to ƒ11 for deep scenes, mind diffraction beyond), use a tripod with 2-sec timer/remote and disable VC/IBIS on sticks, bracket exposures to hold cloud highlights and shadowed foregrounds, use ND for 1–60 s water/cloud motion and a CPL sparingly for glare control on foliage/rock, shield the lens from stray light with your hand/hood for cleaner sunstars, and stitch multi-row panoramas for massive resolution when you don’t want to go ultrawide; whether you’re framing alpine glow, tidal textures, mossy woodland pockets, or desert monoliths, the best Tamron lenses for landscape photography combine light weight, disciplined optics, and confident AF—so your lines stay straight, your corners stay clean, and your scenes feel grand and true.
