I apologize if the breadth of this question requires a response beyond what anyone is willing to contribute. I've started researching optics ( of which I have little knowledge ) and feel immediately overwhelmed. Problem Using a DSLR ( with a DX size sensor ) and preferably the available lens (18-55mm or 18-110mm), what additional optics would allow me to fill the frame and focus on a 35mm wide image at a distance of about 5 1/2"? I imagine maybe a longer lens would help. I've been experimenting with macro tubes and close-up filters without much luck. The close-up filters introduce too many artifacts in the image. I've also considered that a tele convertor may help, but have yet to get my hands on one. Any advice would be super, and I'm sure I left out some details for this equation, let me know what other info is needed.
