This is What Photos Captured with a 50mm f/0.75 Lens Look Like


You might think you have a fast lens if it tops f/1.2 or f/1.0, but that’s nothing compared to the De Oude Delft 50mm f/0.75. It’s one of the fastest lenses in the world, and — compared to other super speedy lenses — isn’t that expensive.

Sure, there’s the f/0.7 Zeiss lens out there, but only 10 of those lenses were ever made. The rarity means that it’s highly unlikely you’d ever get your hands on one, even if you’re loaded with cash.

The De Oude Delft 50mm f/0.75, on the other hand, can be found with a quick search on eBay. Right now they’ll set you back a few Gs:


The lens was originally created for X-Ray photography, but can be repurposed for consumer cameras. Bellamy Hunt over at Japan Camera Hunter recently got his hands on one that was modified to fit on a Leica M mount. The downside is that the lens doesn’t allow you to change aperture (it’s permanently at f/0.75) or focus.

So what do you get when you use this beast of a low-light lens? Here are some sample photographs captured by Qian:




Here are some more sample photographs captured by Aldo Navoni on his Sony NEX camera:









As you can see, the lens is extremely soft and has a razor-thin depth of field (both of which are to be expected). You can also find a larger collection of sample photographs over at the Japanese website OldLens.

    The black and whites look ok but the colours are horrible

  • Rick Scheibner

    Just because you can doesn’t mean you should.

  • Jonathan Maniago

    Sweet! I can’t wait to throw this into my camera bag along with the Lenbabies.

    On a more serious note: This might find some use for still life or detail shots (wedding rings?), but at over $2,600, you’re probably better off freelensing with a cheap 50mm f/1.8.

  • yamaha83

    eh. close ups at that aperture look useless. some farther away images might be cool IMO though? get that brenizer effect going in one shot?

  • 3434346

    looks like shite

  • Clayton Finley

    forgive my ignorance, but why would anyone want this? the all look like instagram filtered cell phone shots with the blurr tool.

  • Justin Sheely

    These images are so …. blurry. I bet I can get the same results with the lensbaby composure without an aperture disc inside, about a f/1.2 equivalent I think.

  • Rob

    Can’t say I dig this lens.

  • josh80

    For the love of God, just turn up your ISO a little bit.. These are awful!

  • Rob

    but even worse than instagram.

  • TN

    displaying a high frustration index, this lens is guaranteed to miss all of those precious moments.. it will leave you wondering where you left your macro focusing rails and tripod.. every time

    srsly tho, this has to be some sort of hard core novelty lens. why someone would spend 2k to get images like these is beyond my ability to project into absurdity

  • Azety

    dont know if lens is bad or photos are just bad.

  • Matthew Neumann

    So…..basically nothing is sharp, ever?

  • Adam Cross

    “The downside is that the lens doesn’t allow you to change aperture (it’s permanently at f/0.75) or focus.” ….. so it’s completely useless then, really, isn’t it?

  • Adam Cross

    the lens doesn’t allow you to focus, it’s a completely fixed lens, so you couldn’t shoot from a distance even if you wanted to. it’s useless.

  • Oj0

    About as sharp as any other lens focused at infinity when used for macro shots!

  • Green Banana

    Wow looks pretty soft and has that 80’s glamor glow. I’ll pass.

  • Edhie Wibowo

    This lens is a joke

  • Dave Phillipich

    Thanks for the examples, now I’m definitely not interested.

  • beano

    Not if you are in radiography. Which is what it was originally designed for.

  • beano

    No use in judging this lens as a regular photography lens. It was never meant to be used like that.

  • Snow Shine


  • Jake

    You just answered your own question. a) People love Instagram effects, and b) Instagram effects are based on real physical effects that people do, like this one. So really, Instagram filters look like this.

  • Richard

    I may aswell just smear vaseline over one of my current lenses and Hey-Ho

  • Ian Evans

    Tack sharp wide open! 5/5

  • RonT

    Or you could use a plastic bag smeared with vaseline, I mean a lensbaby, save yourself a few G’s and still get that quality

  • veraguas

    I have this lens in my collection. Problem is it is so big. You don´t get it close enough to the sensor of a Micro 4/3 camera or a full size sensor camera or a APS camera. So you can use it only for macro photos.

  • carnagex2000

    Ive seen people adapt x-ray lenses to RB/RZ67 and GX680, which would make more sense as you can control the focus thanks to the bellows focusing on them. If anything you can use an adapter with helicoid focusing, its how I use RZ67 lenses on my 5DMKII.

  • Joe Fonebone

    So they go for around $2,500 and have a fixed aperture. Bargain!

  • Anton Berlin

    Garbage lens. Please clean the cosmoline off before use.

    PS – Petapixel – you should know better.

  • Topic_goes_here

    You mean to put on your X-ray machine? OK. … I’m with Edhie on this.

  • AliNoorani

    kind of sad. The poor thing can’t even focus right

  • Devorah Kaye Goldstein

    this is a “beast of a low-light lens” ?? i think this article was wildly successful — in making us all value the gear we’ve got just a little more.

  • Keenan Adams

    Waste of money!!!!

  • Oj0

    This articles has probably saved people thousands of dollars, I’d have expected a certain quality to match the price.

  • Kynikos

    I think I’d like the composition very much on some, if the lens was properly focused. But it’s not, or it can’t be, or whatever.

  • Korios

    Imagine how much this would cost if it was focable and with an aperture..

  • Korios

    I do not think it has macro capabilities and with a fixed focal point it is not meant for detailed shots.

  • Korios

    These samples appear to have a quite fat depth of field, they do not look like f/0.7 equiv.

  • Jigsaw

    Wow, they look terrible. I guess that explains why didn’t make many of these lenses.

  • jwinford

    Not impressed.

  • Manuel Cordero

    Sweet! any chance of some examples?? sounds like a badass kit!

  • Kelly Padgett

    Wow, great lens, said no one ever.

  • Michael Andrew Broughton

    i think i’ll save myself a few grand and just pull a lens out of an old rear projection tv or something.

  • Samuel Ashdown

    $2500 for something you can’t stop down or focus… what

  • Manuel Cordero

    Dear lawdy! thats pretty freaking amazing! i guess im gonna have to adapt it somehow, here in Mexico I dont have many options to get Thanks a lot man!

  • Kyle Michaels

    Or for $50 you can get a Cinephor 7″ f/1.9 lens that covers 4×5 and has a f/0.50 equivalent DOF. How do people think this is big news?
