Step 6: Create your design Your bokeh design must be smaller than the inner circle (60% of the maximum aperture.) The design must also follow all the requirements listed on Ponoko’s templates. The inner circle is 60% the maximum aperture of the lens. The outer circle is the filter diameter size. For example: The 50 mm 1.8 lens has a maximum aperture of 50 mm /1.8= 27.8 mm Multiply this number by 0.6 and you’ll get 16.7 mm Step 5: Create two concentric circles Using your drawing program, create two concentric circles. Then multiply the maximum aperture by 0.6. The diameter that seems to work best for me is 57.477 mm Step 4: Figure out 60% of maximum aperture The maximum aperture of your lens is determined by dividing the focal length by the lowest f-stop. Step 3: Figure out filter size If your lens cap is marked as 58 mm, then your filter diameter will be approximately 0.5mm smaller than the lens cap size.

Step 2: Download Laser Cutting Templates Illustrator, CorelDRAW, and InkScape templates can be downloaded from Ponoko's website. If you have no idea what I’m talking about and need to know what the best lens is, just go buy the 50 mm 1.8 lens (aka the nifty fifty) for $100. which allows for a narrower depth of field and more pronounced bokeh. Since the lens lacks the mechanisms required to zoom, it’s possible for the aperture to be much larger. A prime lens, for those of you that don’t know, is a lens that does not zoom. DSLR - Digital Single Lens Reflex Camera Prime Lens - Lenses with lower f-stops or larger apertures are generally better. Inkscape is a free program that is downloadable here. Step 1: Materials Adobe Illustrator - Other vector-based drawing programs can also be used such as CorelDRAW or Inkscape. The above video tutorial will explain everything you need to know to create your own lasercut shaped bokeh filters. In the meantime I’ve been outsourcing all my lasercutting projects like these custom bokeh filters.
