Congrats are finally getting the whole combo together. Of course now you have to post some obligatory sample images!
I actually ended up shelving my Olympus TCON-17 and bought a Nikon TC-E15ED, which is the 1.5x "little brother" to the much more expensive TC-E17ED that I mentioned above. The TC-E15ED is actually a lot sharper than the TCON-17, but it's also less range and did require a rare (but thankfully inexpensive) step ring. If it matters, it also doesn't look as nice as the TCON-17 on my FZ50 (the TC-E15ED is a rather "skinny" teleconverter).
Anyway, the Nikon gets the teleconverter spot in my camera bag, but I still can't bring myself to get rid of the TCON-17.......yet.
