RX100 + Raynox 250 Sample Macro Shots ...
The Raynox 250 was attached with a MagFilter + 52-43mm adapter. RX100 at 100mm f11. One shot without Raynox at 28mm for comparison. The Raynox at 100mm gives about twice the magnification vs 28mm alone. Also the working distance with the Raynox is much better (subject is further from lens). There are probably better macro setups than this but I have owned the Raynox for several years
20121106 131105 ... is the 28mm alone shot. (The subject is a stainless steel cm scale)
Having DPR insert photos problems but maybe the links below will show up
