Panasonic H-ES35100

The Panasonic Leica 35-100mm f/2.8 is a tiny, razor-sharp telephoto zoom with best-in-class optics. The constant f/2.8 aperture and weather sealing make it a killer travel and event lens. Just make sure you're on a Panasonic body to get the most out of the stabilization, and shop around because prices vary wildly.

Sharpness is where this lens really shines. It's one of the best in our database for optical quality, and owners agree, constantly raving about the crisp detail. The constant f/2.8 aperture is a standout for a zoom this small, giving you consistent exposure and decent subject separation. Autofocus is solid and quiet, though it's just middle of the pack compared to newer linear motor designs. The stabilization is above average and works well on Panasonic bodies, but it's a known pain point that the O.I.S. won't play nice with Olympus cameras. Video shooters will love the micro-step aperture control, but a few have flagged some micro-jitter at the long end when shooting handheld.

Stacked against superzooms like the Sigma 16-300mm or Tamron 18-300mm, this Panasonic Leica trades massive range for a constant f/2.8 aperture and much better optical quality. Those all-in-one lenses are more versatile on paper, but they get dim quickly and can't touch this lens for sharpness. Compared to something like the Canon EF-S 18-135mm, the Panasonic is in a different league for build and light gathering, though the Canon offers a more useful general-purpose range on an APS-C body. If you need a dedicated telephoto zoom and don't want to carry a bazooka, this is the one to beat.

Pricing is all over the map for this lens, with a wild spread from $348 to $1578 across different vendors. That's a massive gap, so shopping around is non-negotiable. At the low end of that range, this lens is an absolute steal for the image quality and build you're getting. At the high end, you're creeping into territory where you could almost grab a used full-frame telephoto, which makes it a tougher sell. If you can snag it closer to that $350 mark, it's a no-brainer for the MFT system.

Panasonic's Leica DG Vario-Elmarit 35-100mm f/2.8 is the telephoto zoom a lot of Micro Four Thirds shooters have been waiting for. It's tiny, it's tough, and it keeps a bright f/2.8 aperture through the whole zoom range. You get a 70-200mm equivalent field of view in a lens that barely weighs more than a can of soda, which is kind of wild when you think about it. The build quality is excellent with full weather sealing, and the internal zoom means it won't suck in dust or change size while you're working.

This is the telephoto zoom for the Micro Four Thirds shooter who values sharpness and portability above all else. It's a perfect match for a small Lumix body as a travel or event lens. The constant f/2.8 aperture makes it genuinely useful indoors or in fading light, something you just don't get from a slow variable-aperture zoom. If you're already in the MFT ecosystem and want a pro-level telephoto that won't break your back, this is it.
