I know the D-300 having used one for a weekend on & off
The D3 & D-700 i know "of"
Ive just been looking at lenses for my D-5000 & they are expensive
When i bought lenses for my Nikon F & Nikormat they also go for my new electronic "F" the F3 the images are excellent The lenses bought new & used are in good order still today
I also have a possibility to buy more lenses from a friend i expect i will buy them as the price is very good 4 for 200? more or less
The snag i cant use them with the D-5000 BUT i could use them with a D-300
or D-3 D-700
The D-300 body & others cost about 1500?
If i buy one & a half Nikon lenses they alone would cost 1500? a top Nikon lense could easly cost more by its self
So a D-300 which could use all my top quality leses would be a saving???
Perhaps the D-3 Or D-700 are light weight replacements for the D-300
What should i do
For the moment im going on with my D-5000 but later should i change or buy sigma?tameron plastic
