Summary: Im happy with my new lens, I use it on a GMC-10 Lumix camera as a complement for the standard 14-42 lens and they cover pretty much all the needs of an amateur photographer as myself. Ths stabilization tool works very good on long range shots, and the lens is luminous enough even at large distances. Portraits come out with great detail been as far as 15/20 meters from the subject. Been using it around a year now without any problems.
Summary: ... to round out a system. Since I had sold my large clunky Canon DSLRs and gone mirrorless with the Panasonic Lumix GX7 this was an obvious choice. Since the micro four thirds system has 2X crop ratio, this becomes in effect a 90-400mm lens. Light, small and sharp. Definitely a good value. Why not 5 stars? A bit dim on the long end as I would have preferred f4.0 but that probably would ruin the bargain aspect of the purchase.
Summary: I bought this lens to take pictures of my daughter doing surf. I wish time speeds up until June in order to properly use it. Try to take some indoor pictures but with medium or low light the picture are terrible, but thats normal. I bought it used and, because I'm in Portugal/Europe and the seller in the US (Texas) I thought it would take ages, but the service was pretty good.
Summary: I bought this lens to be able to use it on my two cameras LUMIX G-2 and G-3, micro. As I already have a lens Lumix G Vario 14-140, needed a 45-200mm, for complete versatility. I consider this lens as good quality, at an affordable price. I have no criticisms to make regarding this lens.
Summary: Bought this zoom lens on eBay for my Panasonic DMC-GF3 camera and took it to the race track. Detail is amazing, and the 200mm zoom (equivalent to 400mm with 35mm cameras) allowed for close-up shots of the cars in the pit stops from the top of the stands. Video performance was also very good. Autofocus could be slightly faster for high speed action like races, though.
Summary: I have been using this product frequently for my recent 3 weeks visit to California. I'm satisfied with the product because: 1. I have been using film cameras for almost 20years and had recently switched to Panasonic G1 because I want to maintain compatibility with my bunch of Leica M lenses and Nikon lenses. The smallness and lightness of the system impresses me. 2.
Summary: I purchased this lens and so far is a very good performer. Please be advised to update the lens as soon as you get it. The lens is not very sharp after 160-170mm, but for the price you can't get anything better in the m4/3 world. REMEMBER TO UPDATE THE LENS FIRMWARE!!!!
Summary: It's a good choice for telephoto zoom with autofocus on micro 4/3rds right now. The Olympus 40–150 doesn't zoom in quite as far, but it starts wider – wide enough that it's better suited for portraits and won't need to be swapped out as often. If you don't already know, you'd be surprised how little the difference is between 300mm and 400mm equivalent zoom, especially compared to how significant 80-90mm equivalent focal lengths.
Pros: Stabilization built into the lens - more effective than IBIS at higher telephoto lengths. Better sharpness than the average kit zoom. Small...very small. 90-400mm zoom range is slightly longer than the average kit telephoto zoom. Nice construction and tactile feel to manipulate (smooth dial movement). No contest - this feels way better damped than a Canon kit lens Focusing lens element is light enough to allow pretty quick CDAF (focusing)
Cons: 90mm equivalent zoom starting length is long enough that you will have to switch back to a standard zoom often. Some people don't like that the manual focus ring is electric rather than mechanically linked... There are good and bad things about that. Images are slightly corner-softened when fully zoomed in, but back off a little or stop down the aperture a bit to minimize that effect.
Summary: I like this as an economical telephoto lens. Pros: price, fairly compact, decent range, rubber zoom ring, smoother zoom than the kit lens, nice picture quality, fast focusing Cons: Hard to use when fully zoomed without a tripod even with the image stabilization
