Olympus M.Zuiko Digital ED 7-14mm F2.8 PRO vs Olympus M.Zuiko Digital ED 8-25mm F4 Pro
Micro Four Thirds
Both are PRO wide-angle zooms for Micro Four Thirds but follow different ideas. The M.Zuiko 7-14mm f/2.8 PRO (May 2015) offers 7 mm and f/2.8. The bulging front element carries a fixed built-in hood, and screw-in filters cannot be attached. It weighs 534 g. The M.Zuiko 8-25mm f/4 PRO (June 2021) reaches 25 mm (50 mm in full frame terms), takes 72 mm filters and is dust-, splash- and freeze-proof. It weighs 411 g.
So you decide between maximum width with f/2.8 and a more versatile travel zoom with filter options.
Which one suits whom?
- 7-14mm: You need maximum wide angle and f/2.8, for astro and tight spaces for example.
- 8-25mm: You want a lighter wide zoom with a filter thread that also covers normal focal lengths.
