No more focus hunting? This Citograph 35mm lens is always in focus

Fixed-focus lenses have been around since instant film cameras — and have stuck around in the digital world to keep shots from GoPros and other action cameras sharp without hunting for focus. But one startup is aiming to bring the spontaneity of fixed focus lenses to the realm of DSLRs and mirrorless. The C.P. Georz Citograph 35mm is a fixed-focus, fixed-aperture lens designed for several different DSLR and mirrorless mounts.

The Citograph, which stems from a Latin root word for spontaneous, aims to bring the speed of a fixed focus to higher-resolution digital cameras. The idea is the same one behind the lenses inside Polaroids and other instant film cameras. The lens is fixed to focus at infinity and the aperture is fixed at an f/8, which is narrow enough to keep a large portion of the image sharp — everything that’s farther than three meters or about ten feet from the camera will be in focus.

The concept isn’t a new one — the hyper-focal distance follows a similar concept but is a technique used with any lens, often for landscape photography. Fixed-focus lenses also remain popular for action cameras and 360 cameras.

However, the lens’ creator, street and portrait photographer Benedikt Hartmann, says the lens is the first always-in-focus lens for DSLRs and mirrorless cameras. Hartmann said he developed the lens to put the spontaneity back into photography, allowing photographers to shoot sharp shots without waiting for the autofocus. With no mechanics in the lens, the camera can shoot instantly, Hartmann says.

The lens is being branded by the C.P. Goerz American Optical Company, a group that produced film lenses from 1886 until the Europe-based company merged with Zeiss Ikon in 1926 and the American branch merged with Schnieder-Optics in 1972. As the first modern lens from a classic company that was absorbed by mergers, it’s unclear if the brand is just a purchased license, such as Kodak’s branded smartphones and tablets that aren’t actually produced by Kodak itself.

The lens uses a Tessar-type design for sharpness and contrast, designed from four elements in three groups. The Citograph lens is also designed for portability to continue building on that idea of spontaneity, weighing less than five ounces and measuring about 2.3 inches long. The lens is expected to be available for Nikon, Canon, Sony, Lecia M, Micro Four Thirds, and Fujifilm mounts.

With the prototype already finished and tested, the lens’ designers are looking to fund the production through a Kickstarter campaign, which just recently crossed its $30,000 goal. If the final testing and production is successful, backers can pick up the lens for pledges starting at $249. The lens will be produced somewhere in Asia and will ship from Germany.

What is a prime lens? Here’s why you need one in your camera bag
nikon z 35mm f 1 8 s review lens 2

If you're new to the world of photography, the idea of a lens that doesn't zoom might seem a bit odd. Even our phones have zoom lenses on them now, or a least a version of zoom thanks to multiple lenses and digital tricks. And yet, some of the best lenses for DSLRs and mirrorless cameras have no zoom at all. While sometimes cheap, these "prime" lenses can go on to cost thousands of dollars. So what makes such a seemingly basic lens so valuable?
What is a prime lens?
A prime lens is simply a lens that doesn't zoom. It gives you one angle of view, and that's it. Fixed to a single focal length, such a lens may sound like a disadvantage, and while that would be true in some situations, primes can also offer numerous advantages.

As prime lenses don’t need the moving parts and extra glass required for a lens to zoom in and out, they can focus on other features. First and foremost, prime lenses often have a wider, or "faster," maximum aperture. The aperture controls how much light enters the camera, and more light means better low light performance, faster shutter speeds, and more. Professional zoom lenses often have relatively fast f/2.8 apertures -- and prices well within the four-figure range -- but even the cheapest 50mm primes lenses can get you to f/1.8, which is over twice the light-gathering capability, sometimes for less than $200.

Designed for sharp shots, Tamron calls its new 35mm prime lens its best yet
tamron sp 35mm announced

Tamron’s latest high-end prime lens builds on 40 years of the Superior Performance (SP) series, and the company says the 35mm offers “unprecedented quality.” Announced on Thursday, June 6, the Tamron SP 35mm f/1.4 Di USD (Model F045) is a high-end wide-angle prime that will be available in Canon and Nikon full-frame DSLR mounts before the end of the summer.

The lens uses 14 elements in 10 groups -- that’s a lot of glass for a wide-angle prime lens, but Tamron says the design combats chromatic aberration while creating sharp images. The company says the lens offers sharpness even toward the edges. The lens construction also uses anti-reflection coatings along with a newly developed coating to fight flare and ghosting.
