Panasonic 100-300mm F/4-5.6 OIS review ready!
The Panasonic Lumix G 100-300mm F/4-5.6 (check price) covers 200-600mm in 135 film format, that’s super tight! Fortunately, the lens weights in at just over 1lb or 512g, and is only slightly larger than a mid range zoom for an APS-C camera! Also, you can think of it as a good 200mm F/4 lens, or maybe a 300mm F/4.5, or 400mm F/5! The lens performs very well from the short end through the middle of the zoom, but is held back a bit by low contrast past 250mm. With that said, at the long end, it will still probably resolve as much or more as a FF 70-400mm lens with a 24mp sensor.
If you like to travel light, and take candid people shots, this is your lens! It also works well as a wildlife lens in good light. Read more here.
