You may’t beat DIY loopy digicam they usually don’t get a lot crazier than this. Constructed by Matt at DIY Perks, this specific digicam encompasses a 432mm f/5 episcope lens with a picture projection circle of round 500mm in diameter. To present you some concept of scale, your common full-frame lens has a picture projection circle with a diameter of at the least 43mm. That’s an space of 0.015 sq. meters. This lens has a picture circle of 0.785 sq. metres (~50x the scale).
And with this large projection additionally comes an enormous benefit in relation to depth of subject. Regardless of being a 432mm f/5 lens, it presents the equal subject of view and depth of subject as a 35mm lens would on a full-frame digicam if it had a most aperture of f/0.4. The closest lens to this designed for the comparatively small full-frame format is the Zeiss 50mm f/0.7, and the final a kind of to promote was rumoured to fetch round $200,000.
The lens itself comes from an Episcope, which Matt demonstrates within the video. It was primarily a device that allowed the projection of real-life objects. Sory of a digicam obscura in reverse. As a substitute of focusing the view from exterior onto the inside floor like a digicam obscura, this focuses the view from the within of the digicam out to the skin world, letting you challenge onto no matter floor you need. This is the reason it has such an enormous projection circle.
Naturally, a lens with a projection circle this massive isn’t going to have the ability to challenge straight onto a DSLR or mirrorless sensor. Effectively, it might, however you’d be seeing a teeny tiny crop from the centre that’s no totally different to taking pictures any 432mm focal size lens on the identical digicam. To seize all the projection, Matt used a trick that was usually utilized in 35mm lens adapters (like these from Letus) when taking pictures to small sensor video cameras. The lens tasks onto a floor after which the digicam movies that floor. This fashion, you continue to get that vast body look on a teeny tiny sensor. Matt actually drives this level residence by utilizing his contraption with a smartphone.
Matt builds fairly the contraption as a way to mount the lens, the display and the digicam, together with Fresnel lenses to beat some vignetting points. However if you wish to make considered one of these your self (assuming you could find considered one of these lenses), Matt may have a obtain pack accessible quickly with the entire plans to present it a go your self.
It appears to be like prefer it’d be lots of enjoyable to make use of, particularly for giant huge location portraits, even when it’s not precisely the simplest factor to cart round!
