In optics section today we will look on photo objective lens attachment Goliton 58mm 2.0X Magnification Tele Converter Lens. When it is mounted to objective photo lens, it receives 2x magnification of image, wherein base objective photo lens should be able to focus on infinity for this attachment to work correctly. It is mounted on lens via 58 mm thread ( there is modification with 52 mm thread ); it has 62 mm thread on frontal side for optical filters. It has 4 lens elements in 2 groups, probably, it is similar to Plossl eyepiece for telescopes ( symmetrical eyepiece with 4 lens elements in 2 groups ), but there is need to look on its optical scheme in order to say precisely. Package contains : Goliton 58mm 2.0X Magnification Tele Converter Lens photo lens attachment itself, frontal and rear caps, storage and carrying pouch and user’s guide. As with all photo attachments : this is attractable solution in terms of price, but there is need to look in shop or read in Internet how it works with given photo lens; and it is desirable if base photo objective lens would have small amount of glasses in order to reduce optical surfaces amount.
