Timothy Fransky Posted October 10, 2018 Share Posted October 10, 2018 I'm taking suggestions for a good wide angle lens for my 627. It came with the standard 20mm sunomatic lens as well as a Taylor Hobson 2.5" tele. (I don't know what that would be in mm, but judging by the matching finder lens, it would appear to be a close-up lens.) Those are pretty standard focal lengths, but I'd like to have a wide option. I suppose I'd also have to find a matching finder lens. Thoughts? Link to comment Share on other sites More sharing options...
Todd Pinder Posted October 11, 2018 Share Posted October 11, 2018 10mm Switar AR would probably be easy to find and not too expensive option. 1 Link to comment Share on other sites More sharing options...
Premium Member Simon Wyss Posted October 11, 2018 Premium Member Share Posted October 11, 2018 20 mm is already a shorter than normal focal length, a light wide angle, with the 16mm system. One inch or 25 mm are normal. In the early days a lens kit would consist of a 3/5 normal, the normal, and a three times longer telephoto. Until the early fifties you had 17, 16, 15 mm wide angles. Then the first retrofocal designs came to the market, interestingly enough a few years after such constructions for the 8mm gauge. Wollensak had a 5.3 mm f/1.5 C-mount lens. Your Taylor, Taylor & Hobson 2½ inch lens is a telephoto. It can serve for close-up shots but offer only rather shallow depths of field. Longer focal length lenses also have a longer end to the focusing range, at five feet or so whereas a normal focal length often goes to about one foot. There are many exceptions to most everything in the optical field. I’d suggest you get acquainted with one particular lens first. You may either become fond of it or not. On a next lens you will surely note differences. That’ll broaden your sense of pictures, technics-wise. 1 Link to comment Share on other sites More sharing options...
Timothy Fransky Posted October 11, 2018 Author Share Posted October 11, 2018 Appreciated. I didn't realize there would be so much difference between 20mm and 25mm in the R16 format. Link to comment Share on other sites More sharing options...
