- Article on Series Filters
References needed: While most series size filters had plain metal mounts. Towards the end of the era of series filters several manufacturers started making screw-in series filters that didn't require a retaining ring or hood to hold them in place. If these are used with some lenses the original hood may not fit. (reference needed.)

- Article on Mercury Cells
Mercury cells came in number of different sizes including the 625 size (i.e. PX13, EPX625, RPX625, KX625, HD625, PN625, RM625, 4625, H1560, H-D, MR9 and the like), the 675 size (i.e. EPX675, HD675, KX675, RPX675, MR44, H-C and the like), the 400 size (i.e. E400N, EPX400, KX400, PM400R, PX400, RM400, T400N, V400PX and the like), and others. By far the 625 size is the most common.
