For me, even before I got my camera I had already ordered the 52mm adapter, Hoya UV filter, 6 layer Hoya Circular polarizer, foldable lens hood, and the lens cap for the adapter. I think these are the "basics" we should have. The uv filter really makes a nice difference imo. I'm still learning the polarizer as at first I didn't like cuz I thought it made things too dark, but now lol I know I can just turn the lens and it's shaded differently der...felt dumb when I realized this. So yesterday was the first time I've used it, and I can see the difference but I haven't done enough yet to really know how to use it.
I had also ordered the Transcend 150X 2GB mem card but later was told you could get the same card a good bit cheaper at newegg.com. All together I ordered $150 worth of stuff from lensmate before even receiving my camera lol.
From what I had read yes Hoya is a good brand. And I really like the lens adapter and lens cap. I leave my adapter on at all times and really like the cap. I bought a nice Sony Handycam bag from Wal-Mart for $28 that everything fits nicely into with lots of room to spare
