Raynox for sony 90mm macro6/21/2023 ![]() CAs are usually pretty minimal. For the price you cant beat a Raynox for getting up to and beyond 1:1. ![]() Image Quality: These lenses are surprisingly sharp in the center and do okay in the corners depending on the main lens. Raynox plastic 52-67mm adjustable adapters are really convenient but they do tend to break The non-DCR models like the MSN-202 and 505 will not cover a full frame sensor are for APS-C or smaller sensors only. No change in effective aperture when using a Raynox as an add-on close-up lensĬorner sharpness is not as strong as the center The DCR-150 works great as a 200mm tube lens! Raynox supplies the lenses with a plastic 52-67mm adjustable adapter you can see in the image below. The DCR-150 and DCR-250 in this set are labeled +1.5X and +2.5X lenses. The two most popular Raynox lenses are the DCR-150 and DCR-250, also available as a set known as the CM-2000. If you are at an effective f/11 at a 1 : 2 ratio, then adding a 2X teleconverter would push you to 1 : 1 but at a new effective f/22! They are very expensive, the usually create very ugly bokeh, and they increase the effective f-number by an additional factor of whatever their power is, 1.4X or 2X. Teleconverters are an even worse choice than extension tubes. To see the increase the effective f-number with an extension tube use the formula: Effective f-stop = nominal f-stop* ( magnification + 1 ). This gives you a nice bright viewfinder image and the ability to use wider apertures for depth of field control or higher shutter speeds if you need them. When you add a close-up lens like the Raynox to a high-quality main telephoto lens you will get added magnification with very similar image quality.Īdding extension tubes to take the lens to 1X forces the lens to focus at a distance that is outside its design which can and will usually causes chromatic and spherical aberrations, vignetting, and effective light loss. With a close-up lens there is no change in effective aperture, or no light loss. ![]() A close-up lens is usually the least expensive and simplest way for someone that does not own a macro lens but would like to try photography in macro magnification territory, 1 X or life-size magnification, or higher. ![]()
