Description: *This listing is a preorder. The Fresnels will be dispatched around 17th July. Please contact me if you have any questions.* This Fresnel Lens screen is for 4x5" (aka 5x4") Shen Hao cameras that have a clipped corner ground glass. The actual size of the Fresnel measures 101x127mm, has clipped corners to match the Shen Hao ground glass, and is optimised for lenses 220mm and shorter*. ----------------------------------------------------------------------------------------------------------------------------------------------------- These Fresnel lenses are designed to be installed so that the grooved side of the Fresnel is touching the outside (shiny) side of your ground glass screen. This is not a focusing screen. My Fresnel lenses have been selected to provide the following benefits: Increase in apparent brightness and more even illumination over the frame. Corners are visible without needing to hunt around the frame, meaning time under the focusing cloth is better spent.Fine grooves. The fine groove width allows ease of focus through the Fresnel with a loupe.Protection of the ground glass. 1.8 to 2.0mm thick acrylic material.Each Fresnel comes supplied in a tin case. Ideal for you to store an emergency ground glass screen.I also stock the following sizes: 3 1/4 x 4 1/4” (Quarter Plate), 9x12cm, 4x5”, 4x5” Clipped Corners, 4 3/4 x 6 1/2” (Half Plate), 5x7”, 13x18cm, 6 1/2 x 8 1/2” (Whole Plate), 18x24cm and 8x10”, 10x12”, 8 1/2 x 15”. Half Plate, 5x7” and 13x18cm also available as special long focus types which are ideal for reducing backs (with longer focus lenses). I also hold a small stock of Fresnels to fit specific camera brands/models: Shen Hao 4x5" (Clipped Corners), Graflex Speed/Crown Graphic 4x5”, RB Super D 4x5”, Graflex Home Portrait 5x7”, Argentum 5x7” Wide Angle, Argentum Long Focus 5x7”, as well as others. *N.B. Ideally, a Fresnel lens screen works best when the focal length of the Fresnel roughly matches the focal length of the lens being used. In the table (photo 3) I have added +20% to the focal length of the Fresnel to mark the upper limit of the optimum range. Lenses of a shorter focal length can of course be used, however the brightness-boosting effect will become less noticeable the wider the lens is. If you have a specific question, please get in touch!
