Summary: When I got the lens from Amazon, I mounted it onto my E410 and began my testing. My standard testing aid (which I found to be very effective) is my old tube type TV. This TV when tuned to a blank channel, is perfect as a test tool because the pixels are quiet large. I took 2 shots with this lens and right away I can see that the TV pixels are very sharp, compared to the 40-150 f4 kit lens!
Summary: Is this the greatest lens ever? No. Is it the greatest for the price? It just may be. After deciding on going the four-thirds route to break into digital photography, I bought a used Olympus camera bundle with kit lenses (the older 14-45mm and this 40-150mm). It looked like I was going to be taking mostly indoor candid shots, so I researched and compared the 14-45mm and 14-54mm lenses.
Summary: This lens (Zuiko 40-150mm f3.5-4.5) is no longer in production by Olympus, but still widely available. I considered this lens and the new model (examining each closely in person, and shooting test shots with an E-520, on several occasions in local photo stores) which replaces it, and chose this lens hands down. Pro: *Equal or better image quality to the new model: chromatic aberration, barrel distortion.
Summary: I just shoot wedding photographs with the lense,quite powerful zoom, easy to handle,lightweight,but on con side,it has no manual/autofocus (MF/AF) option.so autofocus is a bit problem,but overall worth a money for this product for $121.95 at amazon.
Summary: If you recently purchased a new "four thirds" system camera (from Olympus, Leica, Panasonic, etc.) and are looking for a first telephoto lens, you can't go wrong with this one. It's MUCH faster than the most recent generation of 40 - 150 mm lens and has much better build quality. Works really well in hand held situations. Spend the extra money and you will not be disappointed!
Summary: I prefer shooting people and indoors, so I couldn't warrant spending too much on a zoom lens. This one had solid reviews and seems to be clearance priced (as it is discontinued, so out with the old?) So why did I choose this discontinued (older) model over the newer one? Let's compare: Old has F3.5-4.5, New has F4.0-5.6.
