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.

    Well, it looks sharper than when holding some loupe or another type of simple lens to your camera body, but doesn’t render colours as nicely :D

    People tend to spend crazy amount of money on crazy stuff or just for the fun of it. This including photographers.

  • Nick Dakota

    What a letdown. Samples are underwelming and uninspiring.

  • Guillermo Van Olst

    From a technical and engineering stand point I think this is an amazing lens but as a photographer (non iphone, instagram user) I personally would not consider using (and for that matter buying) a lens like this. F.75 is just waaaay too much aperture, your field of focus is tremendously reduced and almost nothing looks in focus.
    My point being its amazingly built but totally useless.

    Pretty sure that’s because there’s more space between the camera and the subject than in the article’s examples.

    I sell this lens & adapter on eBay. It took me from 2009 & trial and error of Five years to get the adapter made correctly that it has a focus range by turning it; in it’s screwmount helicoil in the adapter. The adapter was made for the Sony A7 series of DSLM cameras as the EVF 7.2x manual focus is very necessary for these cameras. Infinity focus is NOT possible as the back focus to chip F.L. = 3mm. Remember the baffle that protects the shutter is 5mm thick on most all Digital designs, so the back of the lens could impact the chip if it wasn’t protected. Thus DSLR cameras are useless with these lenses. Mirrrorless digital is the only way to go and even then, limited. Best regards, Don

    but Instagram filters are free; this is $2,600.

    For that 80s glamour look. :)

    Pretty s**t.

  • Emilio Villegas

    It basically looks horrible.
