An early morning shot outside of Asheville, NC.
I recently bought a brand new Leica Panasonic 12-60mm f2.8-4.0 zoom lens as a back up for the Olympus 12-100mm Pro zoom lens I purchased last year. There are a number of reasons to have two different versions of your most used lenses, not the least of which is the security of having a back up in case a lens is damaged in transit or accidentally dropped. Also, from time to time, even the best lenses can have a defect that renders them unusable and in need of repair.
I bought the Panasonic/Leica as a second lens because I'm been using the Olympus lens non-stop and rely on it for most of my video and photography projects (both personal and professional). Since the Panasonic/Leica covers most of the range it was a good choice. An added bonus is that it works with the dual image stabilization feature on the G9 cameras. With the two camera bodies and two lenses I feel prepared to handle just about anything a typical job tosses my way...
I had read a few reviews on the web that suggested the P/L lens was less sharp than the Oly, and just as many reviews that praised the P/L for its sharpness, so I decided to find out for myself. I would never use a camera body or lens which I have not tested myself on a job so I did a general test last weekend. I found the new lens to be sharp and have good imaging characteristics. It also feels a bit better balanced on a G9 than my Oly 12/100. But the real proof is in day-to-day use.
I have now used it for the last two days and find it to be a very good lens. Interchangeable, for the most part, within the focal length range, with the Olympus lens. It does a great job rendering flesh tones and, like the Olympus, can be too sharp for portraits of people unless their skin is perfect and the light is gentle. Using with correct profiles settings gets you a lens with good fine detail and nice micro-contrast.
I'll keep using it and shooting with it and report what I find.
