What 90mm at f/3.5 actually gives you
90mm is the classic portrait range — long enough to compress features flatteringly without forcing you across the room. On the Micro Four Thirds bodies it covers, it frames like 180mm would on full-frame.
f/3.5 is a moderate maximum aperture. There is less low-light headroom and less background blur than an f/2.8 lens gives, which is generally the trade for lower weight and cost.
Size, close focus and filters
At 272g (9.6 oz) it sits in the middle for handling: substantial enough to feel planted, light enough not to dominate the kit.
Maximum magnification is 2x, meaning the subject can be projected onto the sensor at life size or larger — true macro rather than a close-focus marketing claim. It focuses as close as 13cm.
Filters are 62mm — worth checking against what you already own, since polarisers and ND filters at this size are reusable across any other lens sharing the thread.
Autofocus, stabilisation and weather sealing
Autofocus is driven by a Stepping motor.
Optical stabilisation is built in, which stacks with in-body stabilisation on bodies that have it and does the work alone on bodies that do not.
The barrel is weather-sealed, so rain and dust are a manageable risk rather than a reason to pack up.
