Panasonic 8mm f/3.5 G Prime Lens Micro Four Third

This Panasonic 8mm f/3.5 is a fisheye prime for Micro Four Thirds cameras. Its extreme wide view suits tight interiors. It also works for close, energetic subjects such as skateboarding. The wide frame keeps the action and its setting in one shot.

Panasonic released this lens in 2010 and later discontinued it, so it is an older design. It suits Micro Four Thirds owners who want a deliberate fisheye look for interiors or experimental wide images. Creative portraits and abstract frames are further natural uses. The main trade-off is the fixed f/3.5 aperture, which limits work in dim light.

At 5.8 oz (165 g), this lens is light enough to leave on the camera all day.

It measures 2.04 in (51.7 mm) long and 2.39 in (60.7 mm) across, so it adds little bulk to a compact body.

The 8mm focal length gives an extreme wide fisheye view on the Micro Four Thirds sensor. You can photograph a full interior from one corner, or stand near a moving rider and still include the whole scene. Straight lines near the frame edges bend outward, the signature look of a fisheye. At this width, distant subjects shrink quickly, so the lens rewards close, foreground-led compositions.

Its one maximum aperture, f/3.5, is on the slow side for a prime lens. Daylight and brightly lit interiors pose no problem. In dim rooms you must raise ISO or steady the camera, because the aperture opens no wider.

Closest focusing sits at 0.3 ft (10 cm). You can work very near a subject and still keep its surroundings in the frame. Maximum magnification is 0.2x, so even nearby subjects appear at modest scale in the final image.

The aperture has 7 blades. Stopped down, point lights take on a seven-sided shape in the background. The optics specification scores 70 of 100.

This lens has no image stabilization. At 8mm, camera shake records less blur than it would at longer focal lengths. Handheld shutter speeds can therefore be slower before blur appears. Even so, any stabilization would have to come from the camera body. For a moving subject, a faster shutter speed matters more than support, because support steadies the camera rather than the subject.

The lens has no weather sealing, so keep it dry in rain or heavy dust. There is no fluorine coating either, so the front element needs careful cleaning to shed fingerprints and dirt.

With no front filter thread, you cannot attach a protective filter directly. Given the open front and missing seal, this lens deserves extra care in rough conditions.

The optical path holds 10 elements in 9 groups. One low-dispersion element helps reduce chromatic aberration, where colours focus differently and form coloured fringes along high-contrast edges. Bright window frames in an interior shot are the kind of edge where fringes can show.

Focusing is internal, meaning the adjustments happen among the elements inside the lens. The construction specification scores 38 of 100.
