Excerpt: I use this lens on my Panasonic GX 7 and it works very well. I like the motorized zoom and quick focus. It seems long enough to be very useful, but it is not an all-in-one lens. Too long. But it goes nicely with the kit 14-42.
Excerpt: Got this for my GH4. I already had the 45-200mm but then I read that there was a similar lens with more pro glass, the Panasonic Lumix G X Vario PZ 45-175mm f/4.0-5.6 Zoom OIS Lens (Black). So, I returned the 45-200 and got the 45-175. So far, I like it.B&H is great on returns btw.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Strong Construction

Internal Functions: All lens movement to zoom or focus is internal to the lens. No extended barrel.4. Price. Adorama sold the lens new at a used price. Watch for specials!

Excerpt: I'm very pleased with this lens. Its a nice extension to the kit 12-32mm kit lens for my Lumix GM-1. Use the GM-1 when I want lighter gear that attracts less attention than my Nikon D-800E (e.g., travel, street photos). So far I've used the 45-175mm for street photos and landscapes. I'm very happy with the crisp quality of the images.
