I love my d1h, except the multi selector button just fell off
(anybody know a solution?) black tape is working for now. Anyway,
high iso is great, my favorite subjects are whitetail deer and
other native wildlife, and greatest majority of opportunities are
really early morning or late evening - high iso is a must if you
are going to get pics. I go clear up to 6400 on my d1h, yep, there
is some noise, but getting the picture of that big buck is my aim
and many times it is that or no pic. I have d70 also, but use the
d1h more now that I have it. As far as batteries go, I have 1 nikon
and 1 powermart ($29.95) and don't have any problem at all with
number of pics from a battery. I have in fact gotten 1000 pics on a
fresh charge several times. I hardly ever use the lcd though,
preview is always off. The only problem I see with the batteries is
that they are nicad and they self discharge over time. If you
charge one and let it set a month or just take a few pics, you will
not get many pics per charge at all. This is sometimes frustrating,
and I have been forced into taking the d70 several times when I
went out on the spur of the moment and had not recently charged the
d1h battery and found it almost gone. I am a strong fan of
refreshing the d1h batteries about every 3rd charge also.
