    Creative optics .. 3rd party eye pieces, eye relief, etc.

    Right. Well, the G11 works reasonably well (considering) by using its digital "teleconverter" feature. Since it holds manual presets, it can be pre-tuned for the scope. It's south of sharp, but it looks in focus. As for the micro-4/3rds cameras, having interchangeable lenses they function much...

    I have a Vortex "Viper" 65 HD, coupling a DSLR to the e.p. I'm struggling a bit with consistent results, but have had some very nice luck using 2 different DSLR macro lenses (legacy Vivitars from gosh knows the 1980's?).

    I just picked up a Vortex Viper 65mm spotter... Quickly: The 18mm eye relief with the kit ep seemed marginal to me, but it *does* work with the 50mm "normal" lens on our DSLR. But it might not work with my daughter's Powershot G11. So I find out, Vortex doesn't sell significantly better ep's...
