I currently use the Sigma 105mm F2.8 EX DG on my Sony Full frame A850. It's an okay lens but I use it in manual focus most of the time. I mostly do product like shots like below when I shoot macro.
I've never actually been too happy with the colors out of the Sigma lens. It produces sharp photos and has suitable bokeh but it's never really wow'd me like my Zeiss lenses have.
I'm curious then, if I use a Marumi 2 element apochromatic close up filter +5, what would be my effective mag ratio for a Sony Zeiss ZA 24-70mm F2.8? Its native mag ratio is .25.
Secondary question. If I buy a Zeiss ZF.2 100mm F2 Makro which can be converted to Sony, would it be better to use a macro extension or a close up filter to achieve greater magnification? I know that lens is only 1:2.
