Panasonic has finally delivered the serious ultra-telephoto that L-mount shooters have been waiting for. This 100-500mm lens addresses a real gap in the system, giving wildlife and sports photographers good reasons to consider the Lumix S platform.
It has some compromises, but it solves problems for photographers who need serious reach without excessive bulk.
What Makes This Lens Different
The Lumix S 100-500mm stands out for its manageable proportions. At 2.8 pounds and just under 8 inches long, this lens delivers 500mm reach in a package that’s much more portable than typical ultra-telephoto options.
The size and weight advantages are great when doing extended shooting sessions or when traveling to remote locations.
Beyond portability, Panasonic designed this lens with modern hybrid shooting needs in mind. The Dual Phase Linear Motor provides fast, silent autofocus that shouldn’t disturb wildlife or interfere with video recording.
The 7-stop Dual I.S. 2 stabilization system should let you do handheld shooting at focal lengths where tripods were traditionally required.
Understanding the Reach
The 100-500mm focal range covers huge photographic territory.
At 100mm, photographers get moderate telephoto compression ideal for isolating subjects or compressing landscape elements. Extended to 500mm, the lens enters serious wildlife and sports territory – capable of filling frames with distant birds, isolating mountain peaks, or capturing sports action from the sidelines.
Panasonic’s teleconverter compatibility extends the reach even further! The 1.4x converter provides a 700mm effective focal length, while the 2x converter reaches a 1000mm.
These extensions do come with light transmission costs (f/14 maximum aperture with the 2x converter), but the extra reach proves valuable extreme wildlife situations, or scenarios where physical proximity just isn’t possible.
Optical Performance
The 19-element optical design incorporating UED and UHR glass elements delivers strong performance across the zoom range. Center sharpness should remain excellent even at maximum aperture, while corner performance shows slight softening at 500mm f/7.1 – though this shouldn’t affect practical image quality too much.
The 11-blade diaphragm produces smooth bokeh characteristics beneficial for isolating subjects against backgrounds.
Understanding the Compromises
The f/5-7.1 variable aperture represents the primary trade-off for the compact design. At 500mm f/7.1, available light becomes limited, requiring higher ISO settings or slower shutter speeds. This constraint affects fast-action photography in challenging lighting conditions.
Physical extension at maximum zoom affects balance and field discretion. While still more compact than alternatives, the extended barrel changes the lens’s handling characteristics and visual profile.
Target Applications
Three photographer categories will find this meets their needs:
- Wildlife and birding photographers requiring extensive reach without the weight of large prime lenses during extended field work
- Sports photographers covering outdoor events where sideline positioning limits closenes to action
- Landscape photographers who want telephoto compression effects and the ability to isolate distant landscape elements
The video-oriented features expand the lens’s appeal to hybrid shooters. The f-stop is limiting a bit for video though. Focus breathing suppression and micro-step aperture control does show Panasonic’s commitment to video which are capabilities missing from most traditional telephoto zooms.
Value Assessment
The $2,097 price point positions this lens really well within the professional ultra-telephoto market. The included tripod collar, weather sealing, and advanced stabilization system support the value for serious telephoto applications.
This lens represents significant progress in Panasonic’s full-frame lens development. Rather than attempting universal appeal, it addresses specific needs of the telephoto photographer. The f/7.1 maximum aperture at 500mm isn’t ideal, but the portability and price trade-offs makes the lens worthwhile.
For photographers committed to the L-mount system and serious about telephoto work, this lens deserves strong consideration. It fills a crucial gap in the L-mount ecosystem with strong execution and thoughtful features.
