      I just came across a Canon version of this lens today...how are you mounting it on your camera??

    6. scenery_and_fish 53 months ago | reply

      I bought a set of Nikon macro extension tubes, played around with its configuration (to determine length), and then epoxied it to the Kowa lens. You can do exactly the same with Canon macro extension tubes.

      What does the back for the camera look like? Here's what mine looks like:

      I'm giving this a fav just to show I'm a fan of your ingenuity. Do you have any idea the mass of this thing?

      Amazing. Saw this featured on PetaPixel today.

      no lens would be able to auto focus at this aperture......
      the canon EF 50mm f/1L and f/1.2L have focusing issues at their maximum apertures. plus if an f/0.75 AF lens was made the front element would need atleast a 100mm+ filter thread meaning it will be 1. too large. 2. impractical and 3. very VERY fragile

      Thanks for all the comments!

      Here's the back; sorry for the delay!

      Kowa 65mm f/0.75

      The extension tubes have been epoxied on, and I don't really have a "before" photo, so I'm not sure how much this will help!

      All I know is that it's hefty. I don't have a scale unfortunately!

      Nicely done! That looks very similar to the back of mine. I will definitely take your design into consideration when I get around to building a mount. I also have an idea of using a small piece of pvc pipe and a cheapy mount, but we'll seee! Thankfully all of this stuff is pretty cheap!

      Thanks for all of your help!!

      I absolutely love the dreamy results! Here's a video with a 65mm f0.75 - www.youtube.com/watch?v=aXltb0QqRko . He adapts them himself, for a price. I am in the process of contacting him.
