Sigma 50-500mm lens Filter Holder by Tazgore

Last crawled date: 3 years ago

This is a filter holder that I am using for Solar Eclipse photography. Instead of buying the very expensive threaded filter for this onetime event, I decided to purchase Baader AstroSolar Visual Solar Filter Film. It is typically used for viewing with telescopes, but with this lens adapter you can take photos with your DSLR camera, as this film is rated safe for eyes and electronic pickups. This lens attachement could also be used to hold any Rosco lighting filter.
The hardware that must be purchased are:
2 M3X20 bolts
4 M3X12 bolts
6 M3 nuts
In the photograph I used two plain M3 nuts and four 3mm Wing nuts. I would recomend purchasing the bolts with hex external heads and using M3 x 5mm x 5.3mm Brass Cylindrical Knurled Threaded Insert Embedded Nuts. This would make installation and removal much easier.
