Panasonic Lumix S 100mm f/2.8 Macro Full-Frame Autofocus Lens for Mirrorless L-Mount, Black {67}

Panasonic 100mm f/2.8 Macro: Full-frame 1:1 in 10.5 ounces

A 100mm focal length at 1:1 magnification is a classic macro combination, and Panasonic built this lens around that premise without the bulk that typically comes with it. At 10.5 oz with a 67mm filter thread, it's genuinely light enough to carry all day without reconsidering your kit. The 8-inch minimum focus distance gives you working room between the lens and your subject, which matters when you're shooting insects or flowers and don't want to blow the shot with your own shadow.

Optically, three aspherical elements keep chromatic and spherical aberrations in check across the full frame, which shows up clearly when shooting at f/2.8 in portrait work or when fine subject detail needs to hold. The dual phase linear motor autofocus system pairs a linear motor with a stepping motor, giving the lens fast acquisition that doesn't sacrifice the smooth, controlled movement video shooters need. It stops down to f/22 for focus stacking workflows where depth of field needs to extend across an entire subject plane.

For L-mount shooters building a travel-friendly kit around a Lumix S or Leica SL body, this lens punches well above its weight class in the bag.

Who It's For

Macro photographers working with insects, botanical subjects, or product details will appreciate the 8-inch minimum focus distance and 1:1 magnification on a full-frame sensor. Portrait shooters get a flattering 100mm focal length at f/2.8 with optical corrections that keep rendering clean wide open. Video producers using L-mount cameras benefit from the stepping motor component of the dual AF system, which produces focus pulls smooth enough for controlled narrative work. Travel photographers who want a macro-capable lens that won't dominate the bag will find 10.5 oz a realistic carry weight for multi-day shoots.

FAQ

Is this a true 1:1 macro lens?

Yes. It achieves 1:1 magnification at its 8-inch minimum focus distance, giving you life-size reproduction on the sensor without extension tubes or diopters.

How does the autofocus perform for macro work?

The dual phase linear motor system combines a linear motor for speed with a stepping motor for smooth, controlled focus transitions. It's fast enough for general shooting but refined enough that video work won't show hunting or jarring focus shifts.

What's the working distance between the lens front and subject?

At minimum focus (8 inches), you have roughly 2 inches of clearance from the front element to your subject. That's enough space to position lighting or avoid casting a shadow on insects and flowers without having to back away significantly.

Can I use this for portraiture at f/2.8?

Yes. The three aspherical elements keep spherical aberration minimal at the widest aperture, so you get clean bokeh and sharp subject planes for headshots. The 100mm focal length also compresses perspective nicely for portraits.

Does this lens work with focus stacking?

The f/22 minimum aperture gives you the stopping-down power to stack frames across extended depth of field. You can hold sharpness across an entire insect or small product without needing ND filters to dial back shutter speed.

How much does it weigh compared to other macro lenses?

At 10.5 oz, it's pocket-friendly. Most 100mm macros run 14-18 oz, so you're saving roughly a third of the typical weight for this focal length and magnification ratio.
