It was devised in 1812. It was the first reasonably sharp over a wide field (about 45° at ''f''/11〔(Handbook of photography ), Whittlesey House, 1939, p.37.〕 or ''f''/16) lens. Wollaston fitted it to an artist's aid camera obscura in 1812.〔Kingslake 1989, pp. 23–26, 307.〕 This lens is still used in low-priced cameras. Besides its cheapness, the lens has the advantage of having only two glass-air surfaces. ==References == 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wollaston landscape lens」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
