If no cropping were done, these shots would show the sun twice as large within the frame when compared to the sun in an uncropped 500mm shot. The latter two shots were taken with the 2x teleconverter (TC), giving 1000mm equivalent focal length. Attaching this to the lens doubled the focal length while losing two f-stops of light. And during an eclipse, black polymer is like gold. It worked, but I was at the whim of the winds, quite literally – a gust too strong would blow it off. In haste, I didn't give myself a good way to attach the whole thing to the lens – luckily the ridge on the inset of cardboard was deep enough to simply hang on the lens. The material could then be placed between the pieces of cardboard and held together by using opposing magnets on each corner. I cut out two equally-sized pieces of cardboard and attempted a circular cut in the middle. The filter material needed some kind of apparatus to actually hold it together and attach to the lens.

The black polymer material is a neutral density (ND) 5.0 equivalent, so it reduces the light to the sensor by 16 2/3 f-stops in simpler terms, it lets in 0.001% of the light that would reach the sensor if no material were in front of the lens.īuying a full sheet of the material on eBay was a lot cheaper than buying a specific solar filter, and also allowed me to build any size filter while having material left over to use for viewing glasses or other lenses. The filter polymer material held together between two cut-out cardboard pieces using a small neodymium magnet on each corner. Account icon An icon in the shape of a person's head and shoulders.
