Lens made of ice

Matthew Wheeler took his first picture through an ice lens in response to a challenge by Scientific American and CBC calling on listeners to light a fire with a lens made entirely of ice. Too easy by far – Matthew took it one step farther and started photographing the natural beauty of his surroundings through the ice lenses he made.

Holga lens for Canon EOS cameras from Holgamods

Randy from Holgamods continues to kick ass: he’s now selling a Holga lens mounted on a body cap for use on Canon EOS cameras (Rebel XT, 20D, 30D, etc.). US $34.95, order here.

I’ve ordered cameras from Holgamods before and recommend him strongly. If you want a Holga and don’t want to modify it yourself, this is the place to go. (I have no relationship with Randy other than being a satisfied customer.)

Canon TS-E 24mm lens – a review and discussion

Northlight Images have posted a comprehensive review of Canon’s 24mm tilt/shift lens, which allows a limited set of view camera-like movements for perspective and focus manipulation:

Keith recently obtained a Canon TS-E 24mm 3.5L lens primarily for interior and exterior photography of buildings. There are quite a few reviews of the TS-E 24mm on the web, but we wanted to give a bit more of a feel for what it is actually like to use a shift lens for real (on a Canon EOS 1Ds). Given the very wide angle pictures you can get with a 16mm lens and the ease of correcting perspective in Photoshop, why bother with this manual focus lens and all the extra effort involved in using it? This review/article is intended to give an overview of some of the effects, and has links to more detailed technical info at the end.

DIY extension tube / reverse mount for macro photography

"The following is a tutorial on how to create an extension tube / reverse mount for a standard 18-55mm lens using common plumbing supplies found at your local hardware store… Reversing the lens using a ‘reversing ring’. This special adapter attaches to the filter thread on the front of a lens and makes it possible to attach the lens in reverse. Excellent quality results up to 4x lifesize magnification using fairly cheap, ‘standard’ (not specially designed for macro) lenses can be produced."

Homemade anamorphic camera

f295 member Andrew has converted his homemade anamorphic pinhole camera—where instead of light going straight through the opening and striking the film head-on, the film is formed into a circle and the light is projected into its center from above—to use a lens, and the results are stunning!

Andrew writes, "To get a lens anamorphic camera with the least possible effort I modified the pre-existing ‘black box of hell’ pincam. The p_p_p_pinhole is mounted in the ‘lid’ so I just made a new lid and mounted an 85mm lens stripped off a dead Agfa Isolette…"

Resolving power record with Zeiss 2.8/25 ZM lens

Apparently Zeiss’ Biogon T* 2.8/25 ZM lens for Leica M is ludicrous in at least one department.

From issue 24 of Zeiss Camera Lens News, released today:

"The result was a whopping 400 lp/mm on film, recorded with the Biogon 25 at f/4 in the center of the image. This value, 400 lp/mm, corresponds to the maximum resolution theoretically possible at f/4; in other words it represents the calculated ‘diffraction limited’ performance at this aperture…"

Um, seriously: holy shit.

Of course this is only one specification, and I’d personally be more interested in rectilinearity (the lack of which drives me utterly batshit when I’m after sharp photos) and chromatic aberration, but this is just insanely impressive.

(lp/mm = line pairs per millimeter)
