I know someone had posted similar thread but i just want to know more about it
My current equipments are: Canon 500D and Tamron 17-50mm F2.8
I heard tamron 17-50mm(67mm filter size) if using Raynox 250 will have serious vignetting, anyone have any sample on this?
For Extension tube will it degrade the photos?
Sorry for my noob questions just hope someone can give me some guide ^^; Thank~~
