Panasonic Leica DG Vario-Elmarit H-ES12060E

Great lens and I like it a lot, BUT it will 'trombone' between 40 and 55mm zoom pointing vertically up. This may not be a concern for many users, BUT it should NOT happen on a lens of this quality and price. I can put my camera fitted with the Olympus 12-40mm f2.8, set at 40mm, LENS DOWN on a table and it doesn't move.

I LOVE this lens. I think I just found the one I can’t live without.

I have been waiting forever to be able to buy this lens. I have not shot a lot on it but what I have shot it has been nice. The build quality feels better than the Canon 24-105mm that I use at work. My only concern is it had a slight flaw in glass, but it was not noticeable in the photos. I can deal with it for now. I would definitely buy it again...but now the Lumix S1R is out....

I bought this to replace a 12-60mm f3.5 kit lens (which was actually an OK lens) and have no regrets. The images with this lens are very good as far as color and image quality. This is a little bigger and heavier then the 12-60mm kit lens but paired with my Panasonic G9 it is just fine. I have also used it some on a smaller camera and it was still OK although some may say it becomes a little front heavy.

Perfect walkaround. Could you get sharper with primes? I doubt you would see a difference, and you would have to swap lenses in the field. beautiful design and feel and sharp. You can shoot in confidence at most any aperture and have sharp shots edge to edge.
