I recently purchased a secondhand Panasonic G1 and am completely delighted with both the results it yields and the fact that I no longer have to lug around a Nikon DSLR. I knew when I bought the G1 that I wouldn't find the 14-45 kit zoom particularly appealing, so I've picked up a couple of M-mount lenses (a Nokton 40/1.4 and an M-Rokkor 40/2) plus a couple of Pen F lenses (38/1.8 and 40/1.4).
The method in this "when too many 40mm lenses are barely enough" madness is that I'll eventually figure out which one(s) I like best and then sell the others. (In other words, the standard GetDPI attitude towards gear acquisition.)
Although I very much like the rendering of the M-mount 40's, I'm frustrated by the 0.7 meter (~28 inch) close-focusing distance of these lenses. The Pen F lenses, on the other hand, focus to half that distance (~14 inches), which is perfect for the kinds of still life pictures I want to make with the G1, such as this one, shot with the G.Zuiko 40/1.4:
I'm hoping that someone can suggest how I might be able to achieve the same kind of (14 inch) close-focusing distance with the M-mount lenses. My first thought was an extension ring but this thread suggests that the OUFRO/16469 extension ring for 50mm and 35mm lenses is the only one Leica offered in M-mount and further research indicates that it's designed to give reproduction ratios of 1:1 and 1.4:1. Which is way closer than I want.
It occurred to me that I could possibly ask Jinfinance to make me a custom Leica M to m4/3rds adapter with a deeper than normal tube. The only problem is that I have no idea how much extra depth would be necessary to yield the 14 inch close-focusing distance I'm after.
Alternatively, would it be possible to combine Hawkpeng's Pen F to m4/3 G1 Flange, which requires a W1 Type C-Mount TO m4/3 adapter, together with one or more C-Mount extension tubes to produce the desired effect?
Or perhaps there's another way of achieving my goal that I'm unaware of. Any advice would be greatly appreciated...
