10 out of 10 points and recommendedLightweight - Good sharpness - Power zoomNone, really. If the 45-200mm had the power zoom I would upgrade (to get the extra reach), but it doesn't. I do wish the position of the PZ lever were located lower on the barrel - the actual location forces the user to change from a normal grip in orde
I love this lens. I got it years ago (2013) for use with a GH3 and it's still my overall favorite. The power zoom is great for action and to create interest (for example, start at zero zoom and then zoom out to bring the action closer).reviewed January 31st, 2019 (purchased for $368)
You can get insane reach by using Panny's Ext Tele Con feature (a sensor crop 'zoom' that works with both video and stills). Because of this I often use this instead of the 100-300mm, which is much heavier and lacks power zoom.
You can set up a Function button to activate the PZ, then use the rear controller arrows/wheel to zoom in and out.
The lens is lightweight (light does not mean inferior in this case) and an excellent lens for any G, GX or GH camera. I've used it on all (G9, GX85, GX7, GH3) with great results.
