Hi Coolpix
I bought my D70 with the 18-70 and the 70-300G lenses. I am having great fun with them. I haven't found limitations (except that I am lazy and should use the tripod more when using 300 AND teleconverter)
My advice would be to PM Birddog and see exactly what he meant by his comments of
and
I bought my gear from him and am very happy
If you only want to buy one more lens then it depends how much you want to spend and what you want it to do. But if you can afford to, maybe look at something like the 70-300G now and start putting the bucks away in case your photography finds its limitations and you need / want / desire more.
But for me, I am loving it.
I had the loan of my bro in law's 80-200 F2.8 big phallic thing that. Great lens and all but he bought it second hand a few years ago for $1250. I have seen that same lens on ebay recently for a little over $600. Nice and all but I need to find out what VR is - but no hurry for me because as I say, the 70-300G is fine for me, and that's AFTER the loan of the phallic monster I had to give back.
And for me, macro is a screw on filter-type magnifying glass looking thing I originally bought for my F80. Haven't had the D70 long enough to have a good play with that.
Good luck in your choices
Adam.
