Scenario-by-Scenario Tests to Run in Sony Lens Compare Beta
1) Landscapes & Architecture (Edge-to-Edge Sharpness + Distortion)
What to test in the Beta: Compare center vs mid‑frame vs corner sharpness at 12mm, 18mm, and 24mm on the 12–24 GM, and at 24mm on the 24–105 G. Toggle apertures from wide open to f/8–f/11. Examine distortion and geometric rendering on building lines.
- 12–24mm f/2.8 GM: Expect superb corner acuity for an ultra‑wide, minimal smear, and strong control of complex distortion—ideal for interiors and tight urban vistas.
- 24–105mm f/4 G OSS: At 24mm, very good corners stopped down and low distortion for a standard zoom; not as expansive as 12mm but more versatile overall.
2) Interiors & Real Estate (Field of View + Vignetting)
What to test in the Beta: Run vignetting comparisons at the widest focal lengths. Check how much room coverage you gain at 12mm vs 24mm and how quickly edge shading clears by f/4–f/5.6.
- 12–24mm f/2.8 GM: 12mm lets you capture entire rooms in one frame. Any wide‑open vignetting typically evens out by stopping down slightly.
- 24–105mm f/4 G OSS: Start at 24mm and consider multi‑shot panoramas if you need more width; benefits from OSS for handheld ambient shots.
3) Astro & Night (Wide Aperture, Coma, Star Rendering)
What to test in the Beta: Inspect wide‑open performance for sagittal coma and star shape at the frame edges. Compare 12mm f/2.8 vs 24mm f/4 for exposure and corner rendering.
- 12–24mm f/2.8 GM: The f/2.8 advantage lets you lower ISO or shorten exposures, with strong coma control—great for the Milky Way and night cityscapes.
- 24–105mm f/4 G OSS: Usable for night scenes, but f/4 means higher ISO or longer shutter; OSS helps with static subjects, not stars.
4) Travel & Everyday (Range, Portability, Stabilization)
What to test in the Beta: Evaluate sharpness across the 24–105mm range at f/4–f/8 and check how OSS helps at slower shutters. Compare 24mm and 50mm framing to see practical coverage vs the 12–24’s dramatic perspective.
- 12–24mm f/2.8 GM: Compact for its class but still substantial; unbeatable for sweeping scenes and tight spaces.
- 24–105mm f/4 G OSS: One‑lens travel solution—wide to short‑tele reach for landscapes, street, details, and informal portraits, with stabilization for low‑light interiors.
5) Events & People (AF, Bokeh, Subject Isolation)
What to test in the Beta: Use AF tracking charts and sample portraits at 35–85mm equivalents (where applicable). Compare subject isolation at f/2.8 ultra‑wide vs f/4 standard zoom.
- 12–24mm f/2.8 GM: Ultra‑wide perspectives are dynamic for environmental portraits; f/2.8 helps in low light but background blur is limited at these focal lengths.
- 24–105mm f/4 G OSS: At 70–105mm, compression and f/4 yield flattering portraits and cleaner backgrounds; OSS aids in dim venues.
6) Video & Gimbal (Focus Breathing, Stabilization, Handling)
What to test in the Beta: Check focus breathing charts or sample pulls, and compare hand‑held footage with/without OSS. Evaluate corner sharpness while panning and the steadiness of walk‑and‑talk footage.
- 12–24mm f/2.8 GM: Ultra‑wide FOV inherently steadies handheld shots; look for minimal breathing and consistent sharpness during moves.
- 24–105mm f/4 G OSS: OSS + mid‑range focal lengths make it a flexible run‑and‑gun lens; test stabilization effectiveness at 70–105mm.
7) Close‑up Details (Magnification & Micro‑Contrast)
What to test in the Beta: Compare maximum magnification and fine‑detail rendering on textured subjects (fabric, foliage, signage) near MFD.
- 12–24mm f/2.8 GM: Can focus close for dramatic foreground emphasis; not a macro option.
- 24–105mm f/4 G OSS: 0.31× at 105mm provides satisfying close‑ups for food, details, and small products.
8) Flare, Ghosting & Sunstars (Backlight Performance)
What to test in the Beta: Shoot against strong light sources and compare ghosting, contrast loss, and sunstar rendering at mid‑apertures and stopped down.
- 12–24mm f/2.8 GM: Advanced coatings and 9‑blade diaphragm deliver clean sunstars and well‑controlled ghosting for an ultra‑wide.
- 24–105mm f/4 G OSS: Good flare resistance across the range; compare sunstars vs the GM when stopped to f/11–f/16.
9) Color & Rendering (Consistency Across the Frame)
What to test in the Beta: Compare color neutrality, contrast, and micro‑contrast at identical focal lengths (24mm, f/5.6–f/8) on the same scenes. Inspect mid‑tones and skin tones.
- 12–24mm f/2.8 GM: GM coatings and optics tend toward crisp micro‑contrast and high clarity, especially in fine textures.
- 24–105mm f/4 G OSS: Pleasant, natural color with good contrast; strong consistency throughout the zoom range.
10) Build & Handling (Field Practicality)
What to test in the Beta: While weight and dimensions aren’t visual tests, simulate your shooting: imagine all‑day carry vs dedicated outings. Check how focal coverage impacts your lens swaps and kit size.
- 12–24mm f/2.8 GM: Specialized, premium build; rear gel filter slot for creative control without large front filters.
- 24–105mm f/4 G OSS: Lighter, smaller, and accepts common 77mm filters; a simpler everyday carry.
