Port Locks for FL Port System (Set of 4) Product Overview Set of four port locks. focus of 0.38m) the result with single lens diopter was unacceptable. The Modular Port System allows you to build a dome or flat port out of. For example I found that when using one with a 24-70mm zoom (min. These may degrade the image to the point of uselessness - it varies by individual lens design. The solution is to use a close-up diopter lens. at minimum focus (e.g., 0.45m) the lens is focused beyond infinity when behind a dome. Most 50 1.4 lenses cannot focus close enough, i.e. The resulting air space between the dome surface and lens could also be problematic in terms of rig buoyancy.Īlso important is the distance to the dome port virtual image is quite close. For example with a 105mm macro you would need to move the dome port some distance way from the front of the lens and you may lose some of the lenses macro capability. As well, one cannot avoid the field curvature of the virtual image. Florida Port Charlotte Lenses (current page) Category: Lenses Showing: 8 results for Lenses near Port Charlotte, FL.
However, one needs to properly set up the dome port (correct amount of port extension). This also results in the removal of the magnification (that you get with a flat port - see Bill's comment) and thus variability of magnification related to chromatic aberration. The Florida State Golf Association provides Florida golfer club, course, and tournament information, as well GHIN handicap, junior golf services, and much more. The main purpose of the dome port is to restore the angle of view of the lens. The non-SLR Nikonos 35mm lens used a flat port - this is why it was amphibious and not underwater only (all the non-SLR Nikonos lenses with focal lengths <35mm were under water only). One can get away with a flat port with a 35mm focal length on the 24x36mm format for example. Therefore one can only use flat ports with near normal focal lengths and longer. It gets much worse as the angle increases. Behind a flat port the chromatic aberration is a function of the angle of view measured from the optical axis, i.e., the half angle.

This results in chromatic aberration which can be seen even in a swimming pool. What is not often stated is that the refractive index of water varies by wavelength of light.
