Summary: Added to my lumix DMC-GM1 this gives incredibly long range shots of amazing clarity. Because of the internal zoom it isn't too big and is quite light so the balance of the camera isn't affected unduly. Good value worth looking at.
Excellent lens - high quality images and very responsive
23 April 2014
Summary: I have used this lens for the last week and taken over 100 images with it. I am really impressed with the detailed images - significantly better than the Panasonic 45-150mm f4-5.6 which I also own. The zoom reach is great, and the way the zoom works (internally) is superb - it is really quick and it means the lens doesn't extend at all. The barrel coupling to the lens is clearly electronic but the linkage is really well done and hardly noticeable.
Summary: This lens really completes the Pansonic G5 and its well worth the money as its so reasonably priced for a great lens. I highly recommend you llok at buying this product from Pansonic if you have a G series camera.
Summary: First class lens. Expensive ? depends where you buy it from. Mine cost me £276.00 Sharpness is very good at full aperture reaching max sharpness across the frame at f8. CA is non existent and fall off at the edges minimal. Having a long lens that doe not "trombone " is great. You do not have to use the zoom motor, manual zoom is very fast. However you can set the power zoom to slow medium and fast in the cameras menu. I am using a G5 could not afford the GH3 !!
