Panasonic’s Longest Zoom Yet: Compact Power in a 100-500mm Lens

The Panasonic Lumix S 100-500mm f/5-7.1 O.I.S. lens gives you reach that’s rare in a package this compact. Wildlife, sports, and travel shooters often need long focal lengths, but carrying massive lenses adds weight and hassle. This lens aims to fix that by stretching all the way to 500mm while staying small enough to fit comfortably in a standard kit bag.

Coming to you from Jay P. Morgan with The Slanted Lens, this detailed video takes a close look at the Panasonic Lumix S 100-500mm f/5-7.1 O.I.S. lens. At first glance, the standout feature is the focal length range. Getting to 500mm in a lens that’s not oversized gives you flexibility, whether you’re shooting animals in the distance or isolating details in a landscape. Morgan demonstrates how the tripod collar and Arca-Swiss plate make it easier to mount, though you can remove the collar entirely if you prefer handheld use. The video also points out the image stabilization options, autofocus/manual focus switch, focus limiter, and zoom limiter. These design choices make the lens quicker to use in the field when timing is critical.

The ability to pair this lens with teleconverters pushes it even further. Using a 1.4x gives you a 700mm reach, while a 2.0x gets you to 1,000mm. Morgan shows how the lens manages this without becoming bulky, though you’ll be limited to starting at 150mm with the converter attached. Combined with crop zoom, he notes you can push past 3,000mm for extreme reach. This flexibility makes it attractive if you need one lens to cover a wide range of shooting scenarios. There are trade-offs, such as the zoom smooth-to-tight control being a bit too easy to bump, but overall, the balance of size, weight, and versatility stands out.

What makes this lens more practical for travel is its portability. Morgan points out it’s not much larger than a 70-200mm, making it easy to fit in a bag alongside other essentials like a 24-70mm or 16-35mm. At 2.8 pounds, it’s lighter than many alternatives in the same focal range, and its 82mm filter thread means it can share filters with other common lenses. He also demonstrates its respectable close focusing distance, useful for insects and small subjects without having to crowd them. Check out the video above for the full rundown from Morgan.
