1) AF540FGZ and Nikon SB 22. I'm currently hunting for reasonably priced SB 25s and SB 28s. The price of SB 26s (if you can find one), has gone through the roof over the last little while. Hmmm. I wonder why?
Currently I'm triggering the 540FGZ with the built in flash. When that doesn't work, I use the F5P TTL cable and shoe adapter. If that's too short I watch TV. I have an order on the way from flashzebra.com, so once that arrives I'll be able to get past the above mentioned problems.
I too can vouch for the reliability of Pocket Wizards, but I'm pretty sure I'll be buying a set of Elinchrom Skyports in the not too distant future.
2) Portraits and still life.
