Pros:That's the best! Materials, tropicalization, stabilization, distance and speed of focus, size, sharpness, constant f 4 light,
Opinion:L I used with a m 10 mark ii, which I wanted to sell, since I tried this I totally changed my mind. A fantastic lens, versatile and sturdy, sharp, with a long hike and precise fast focus! Sharpness from 12 to 100 mm. Good bokeh. Perfect x who wants to travel and x who wants to have a lens all do of excellent quality! I recommend it to anyone who has a 4 m 3 car.
Pros:Stabilization! Compactness, materials, lightness, versatility, price value, speed to set parameters and customisation of keys.
Cons:Noise at ISO highs, from 2000 and up. Focus tracking and focus c.
Opinion:It took me a year to choose before I bought it. Chosen mirrorless instead of sLRs for size, chose olympus instead of fuji x stabilization. Fantastic materials, you feel you have a jewel in your hand, vintage charm but in step with the times. The only flaw the focus c and the tracking, did not meet my needs. At the high ISO a lot of noise. I didn't appreciate it until I changed my lens from kit 12 50, and I switched to a fixed, and to the pro series. Great for those who want to start, great for those who want to travel, if you take a 12 100 pro, you will not need more x travel. Great if you pair it with pro lenses, you save in the machine body but invest in good-crafted optics.
