I have a D70.., love it... however here are the pros and cons
Pros: professional pic
unbelievable quality and zoom capability
enlargements are crystal clear
great manual capability or you can leave it on "point and shoot"
I have had very very few bad pics
rapid shooting for sequential photos
Cons: heavy like the old SLR's (but at times worth it)
larger body so doesn't fit in the typical small purse
I love it and keep dragging it with me because my little cameras (and I am a camera junkie) just don't have the quality this one does. If you get one, I would still carry a little point and shoot (or a disposable) with you for what I call "run around" pics.. ones that are purely candid and not planned.
I haven't been on a cruise yet, but am going in March 07. I plan on taking my D70 along with my little one...
To end.. I think the most negative comment I could come up with is that it doesn't fit in my purse (unless I carry a big bag) If I am going with my SO then of course there is ho problem.. he carries it :grin:
Hope this helps
