Question about Sigma Macro 50mm f/2.8 EX DG for Nikon AF
Hello, I'm trying to get a handle on an image problem I'm having when I use the Sigma 50mm Macro with my Nikon D70. The issue is that when shooting extreme closeups, the central portion of the image is washed out and lacks good definition. This is particularly noticeable on medium to dark images, as you can see in these pictures I've posted on my Google account: http://picasaweb.google.com/RLT1960/SigmaLens.You can get more info about the specific pictures by clicking on the "more info" link for each picture. This is not a problem with the camera, as the image problem does not occur with my 18-70mm Nikon lens. I've cleaned the sensor, removed the haze filter (thinking it might possibly be a problem with light reflecting on the filter) but the problem persists. Any help would be much appreciated! Lee
Please try to look at carefully at the center of your front and rear lens,see if there is a fungus or any dirt in the middle,or try to look reversely full open facing the light so that you may confirmed the cause of the problem.
