You just need a 67mm ND filter like these (AT LEAST 16 stops):https://www.amazon.com/CONCEPT-ND100000-Neutral-Multi-Layer-Coatings/dp/B0CPXJ2YF3/ref=sr_1_3?https://www.amazon.com/Concept-ND1000000-Multi-Layer-Waterproof-Resistant/dp/B0CRVJSR37/ref=sr_1_4? These filters do screw in, so they may be harder to remove quickly once totality hits. Or something you can put over the top of your lens like this:https://www.amazon.com/Celestron-EclipSmart-Telescope-Standards-Photograph/dp/B0CH45ZBKV/ref=sr_1_4?Measure the outside diameter of your lens to see if it would fit. Or you can make something yourself using solar film.
