- sharp wide open in centre but loses it as you go outwards, especially beyond 100mm
- hits f/5.7 at 50mm
- versatile but not great image quality but that is the price to pay for a very light, compact, weather resistant lens of such zoom range

- “At equivalent ranges, the lens performs better than standard Olympus kit zooms such as the 12-50mm f/3.5-6.3 or the 40-150mm f/4-5.6 R”
- “similar image quality to the M.Zuiko Digital ED 14 150mm f/4-5.6 II”
- corner sharpness improved on stopping down to f/8-11 but centre sharpness may fall a little
- great for backpacking with minimal kit, or if you want a versatile optic that you can also use for shooting videos and vlogs
- If a travel zoom with ultimate image quality is paramount, the Olympus 12-100mm f/4 Pro might be a better alternative although it is more expensive, longer and 25% heavier with less reach

- soft even in the centre at 200mm but otherwise centre sharpness is very good
- very fast AF 33ms from infinity to closest
