I'm using the Sony SAL-50M28 macro lens with a Sony alpha 350. I'm trying to shoot a 140mm x 40mm white piece of paper in front of a white background. Everything is very white. On autofocus mode, it never finds the focus, so I'm using manual. The shooting distance is about 45cm. Because everything is so white, I find it very hard to get a sharp focus through the viewfinder, if I use the LCD the screen all I see is a white screen.
I tried to shoot through a range of focus by turning the focus a little at a time. Took about 20 shots but none of them are sharp. I'm using tripod, without remote. The tripod isn't that steady and camera does move a teeny weeny tiny bit when I press the shutter. What should I do?
