Hi Melanie:
It looks like you are getting the hang of the 90 very quickly. Nice shots!
The 90 is a lens that I keep thinking about quite a bit. I have read a fair amount about it, but I do have a few questions. I hope you don't mind. First, how difficult is it to Manual Focus? Could you tell me what camera body are you using for reference? I realize that this lens is mostly a tripod mount type of lens, but could you use it handheld for some shots? How are you doing your metering?
