[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]The focussing screens I have are made by differing companies, here in England both Cook and Perkins, Periflex and Stewartry all made appropriate devices, I also have an anonymous Japanese device. They normally turn up cheaply, un-loved and un-known, at camera fairs for around 5-10 UKP. They were made as basic close up devices. Usually a clamping ring held an extension tube with your lens on the end of it, (this was situated on a tripod) and then you screwed in the focussing screen, once everything was in focus, you stopped the lens down, unscrewed the focusing screen and replaced it with the Leica - taking care not to knock the tripod/extension tube/lens etc. Then you pressed the shutter... Rather convoluted and the common Focuslide took a lot of that 'palava' away. If you're still interested and can't find one, I'll let you have one of mine for 10UKP. Mail me privately if you're interested.
