An unbelievably small lens is coming for Sony E and Nikon Z cameras

Viltrox will shortly launch an Indiegogo crowdfunding campaign for a tiny new pancake lens for full-frame Sony E- and Nikon Z-mount cameras. Called the AF 28mm F4.5, the lens could well become the smallest lens available for both camera brands, and is nicknamed 'chip' on account of its potato chip-/crisp-like slimness.

Measuring a mere 15mm long and 60mm in diameter, the lens is barely thicker than a camera body cap and weighs just 60g. It closely resembles the design of Olympus's Fisheye Body Cap 9mm f/8 lens, although the two lenses have a very different focal length.

Naturally, Viltrox had to make some compromises to create such a slim lens. The primary sacrifice being there's no diaphragm, so the aperture is fixed at f/4.5. Another unusual omission is that the lens lacks a manual focus ring, largely because it's so slim there isn't really room for one. Thankfully Viltrox has managed to find space inside the barrel for a VCM coil autofocus motor, so despite the tiny dimensions, focussing is a breeze. Another nice touch is the integrated lens shutter 'cap', which can be flicked open or shut using a small lever on the front of the lens.

You'd expect that a lens this small and simple would be inexpensive to buy, and you'd be right. The Viltrox AF 28mm F4.5 FE is priced at $99, with early campaign backers said to receive a 30% discount.
