New Kickstarter Funds a 120mm f4 Petzvar Lens for Hasselblad 500 Cameras

photo-original

Petzval lenses are really, really fun and very addicting to play with. While we love the ones available for full frame 35mm camera sensors, it would be even better to get one for a medium format camera. That’s what photographer Denys Ivanichek is trying to create in a new Kickstarter. This lens would be available for medium format Hasselblad 500 and 200 cameras, like the 500C.

In medium format, 120mm is a portrait focal length of around 85mm as a full frame 35mm equivalent.

The New Lomography Petzval 58mm Lens has Bokeh Control

Petzval58_mood02

Lomography already has a Petzval lens designed specifically for portraiture at 85mm, but this time around they’re designing one with a closer to normal field of view. Today, the company is introducing the Lomography Petzval 58mm lens, and they’re kicking it off with a Kickstarter.

For those of you not in the know, the Petzval lens was so hot not only because of the beautiful swirly bokeh, but also for the excellent colors. In fact, it has some of the best colors that we’ve seen.

With a minimum aperture at f1.9, the lens also has a special new feature called the Bokeh Control Ring. This allows you to change the type of bokeh that you get from the image. It uses the Waterhouse aperture system which requires you to literally put the aperture key into the lens via a slot. You’ll get a bunch of these keys to go down to f16.

The lens is available in Canon EF or Nikon F mounts in either brass or a black finish. More info and images can be found below or on the company’s Microsite.

A Tour of an Antique 1800’s French Petzval Lens

Screenshot taken from the video

Photographer Brandon Edwards created a video on an antique Petzval lens that he own. He’s sure it’s from the 1800s and originally made in France, but can’t totally verify it. Brandon gives us a history of the lenses and essentially tells us that this lens was the Canon L equivalent of its time because of the much shallower depth of field.

Lenses like these were created using math by Joseph Petzval and later on were improved by the Voigtlander company.This lens is so unique because for many years, science and math wasn’t used to create lenses. But in this case, it was to ensure the best image quality. This would affect the production of lenses for years to come.

A tour of the Petzval lens is after the jump. But for a more modern take, check out Lomography’s offering.

The New Lensbaby Velvet 56 Has an f1.6 Aperture

velvet56_bk_standing_1534

Today, Lensbaby has announced a brand new optic for their system: the Velvet 56. This 56mm lens comes with an f1.6 aperture and can focs as close as five inches. With a 62mm filter thread on the front, Lensbaby also hints that this lens was designed to give off a look akin of that of mid-20th century lenses (which basically means something like the Lomography Petzval lens).

The company is billing this lens as a high end lens and says that it delivers a velvety glow that gives digital cameras a film-like quality when using it.

The Lensbaby Velvet 56 comes in at $499.95 and is available in Canon, Nikon, Pentax and Sony DSLR mounts.

Sample images are after the jump. We’re trying to call one in for review now.

Review: Lomography Petzval Lens (Canon EF Mount)

Chris Gampat The Phoblographer Lomography Petzval Lens product images (13 of 13)ISO 4001-50 sec at f - 4.0

Lomography hasn’t always been known as a company that caters to the higher end crowd or market, but they’ve been taking steps to attract more of that market share without giving up their identity. And perhaps the best known attempt so far has been the company’s Petzval lens. This is an 85mm lens designed with a special interchangeable Waterhouse Aperture system along with some very swirly bokeh. There surely are lenses that still have this effect that are made in both China and Russia–in fact, Lomo teamed up with Zenit to create this lens.

Featuring a maximum aperture of f2.2, a 58mm filter thread for video shooters, and a minimum focusing distance of one meter, the Lomography Petzval lens is something that you probably won’t bring out with you often–just like any other specialized lens. But when you do, you’ll have loads and loads of fun.

New Kickstarter Aims to Create the Petzvar 120mm f3.8 Medium Format Petzval Lens

7409fdb81fd7ef0cc9032c279bf1a33e_large

Earlier on this year, the Lomography company announced the development of a Petzval lens for Canon and Nikon DSLR cameras. While that one has a super classic look to it, a new Kickstarter wants to aim for those reaching for higher fruit. The Petzvar is a 120mm f3.8 medium format lens that is using the crowd sourcing platform to make the lens come to the mass market. The lens will be designed for medium format cameras (specifically Pentacon P6 mount) but will work with 35mm full frame cameras via an adapter. In a case like this, it might work best with a Sony A7 or A7r unless you get a split image focusing screen.

Like other Petzval lenses, it will be sharp in the center with a swirly effect on the corner. Additionally, this lens will have a very clear, cool, modern look to it. If anything, it looks like something made by Zeiss.

The Kickstarter video is after the jump, but it doesn’t show very much to it. Tech specs and sample images are also after the jump.

So What Exactly is a Petzval Lens?

c91bd746d1ccb95ef0464589a01be75b_large

In the early days of photography (think 19th century), there wasn’t a whole lot of options with regard to cameras and lenses. There was no Canon or Nikon or Leica or Olympus or Pentax and definitely no Sony, pickings were slim. Charles Chevalier had developed one of the first lenses for the original Daguerre & Giroux camera of 1839; despite being one of the first, it had some glaring issues, such as an overall lack of sharpness, and pitiful maximum aperture of f15, which caused exposures to quite long. Obviously, someone had to come up with a better solution; enter Joseph Petzval.

Lomography’s New Petzval Portrait Lens Mounts to Your Canon or Nikon DSLR

Petzval_lens_quarter2

We had a surefire feeling that Lomography would be trying to take a step into the more serious direction after they announced their Bel-Air camera–but we had no idea that it would be this badass. A couple of days ago, we received the news about their just announced Petzval Portrait Lens for Canon and Nikon DSLRs and SLRs, and we were all freaking out. Petzval lenses are ancient optics that are designed to give swirly backgrounds in addition to out of focus bokeh. But Lomography is making a brand new one with Zenit in Russia; and their Kickstarter to make it happen launches today.

This lens is a fully glass optic with a fully brass exterior. To change the aperture, you’ll need to use a slider (called the Waterhouse system) with interchangeable apertures–just like in the old days. Plus, it will obviously be a manual focus optic. In the end, it equates to an 85mm f2.2 lens–which has a faster aperture than any other lens like this out there. The reason for this partially is because many of these lenses were for a larger format. Sure there is going to be vignetting and field curvature, but that is one of the beauties of Petzval lenses.

You can expect it to hit shelves in February of 2014 for $499, but the company is also confident that they’ll ship the first units out this December. If you donate a certain amount to the Kickstarter, you can even get your name engraved on it. Tech specs are after the jump.
