Hi CS bros,
I read through the closeup filter thread, but I don't know how to do the calculations.
I currently have a sigma 70-300mm macro. the macro working distance from lens front to subject is 0.95m
So if I get a Closeup+4 filter, what will be the new macro working distance? Which means how close can I go up to my subject?
At the moment, with my lens front range at 0.95m, it's very hard to take closeup subjects to get a bigger macro view. So i'm thinking what closeup filter range i should get to go up to at least below 0.5m or to 0.25m.
Thanks in advance.
