Panasonic Lumix G Fisheye 8mm F3.5 hands-on preview

The Lumix G Fisheye 8mm F3.5 is the eighth lens Panasonic has released for Micro Four Thirds, and sees the company venturing away from mainstream optics towards something a little more exotic. Fisheyes are ultra-wideangle lenses which project images in a different way from conventionally-corrected rectilinear designs - straight lines are rendered as curves unless they pass directly through the center of the frame, with the curvature ever-increasing towards the edges. In essence, accepting this extreme barrel distortion makes it possible to design a lens with a much larger angle of view than is normally possible.

The 8mm F3.5 is a so-called 'diagonal' fisheye, which means it has a 180 degree diagonal angle of view and the projected image covers the entire frame. This is in contrast to 'circular' fisheyes, which give a 180 degree angle of view in all directions, but only form a circular image in the middle of the frame surrounded by a non-illuminated black border. Panasonic claims it's the world's smallest and lightest of its type, and that's easy enough to believe; a cursory glance at its specification reveals it to be remarkably compact and lightweight, weighing in at under 6 ounces and measuring less than 2 1/2 inches in length.

We must admit to feeling more than a little surprised to see a fisheye appearing from Panasonic right now, when we can't help but feel there are a couple of gaping holes in the Micro Four Thirds lineup that surely need filling more urgently (most notably a fast portrait prime in the 50mm F1.4 range). Then again Sony has chosen to produce a fisheye option for its competing NEX system from day one (albeit by the more flexible option of an add-on converter for the 16mm wideangle pancake), so clearly there's something we're missing here. Presumably there's sufficient demand for 'edgy' close-in shots of snow/skateboarders or wide sweeping vistas of sports stadia is sufficient to justify the development costs.

These doubts notwithstanding, we've had an early sample of the 8mm F3.5 fisheye (which we're told is representative of the final optical quality) in the dpreview basement for the last couple of days, just long enough to put together a brief overview of its design and bring you a small samples gallery.

I want a circular image and will stick with my adapted Sigma 4.5mm f2.8

""Autofocus

The 8mm focuses quickly, accurately and near-silently, just as we've come to expect from Panasonic's Lumix lenses. It shows fairly pronounced focus breathing, with the angle of view getting narrower on focusing closer. This has little practical impact, but does result in a visible 'jitter' during autofocusing when used on the Olympus bodies.""

What does :

"......but does result in a visible 'jitter' during autofocusing when used on the Olympus bodies.""
