I keep reading about FX replacing DX, the need to sell DX lenses etc. All this is madness. DX is going to be the vast proportion of sales, not just now but for ever. DX isn't dying out - it is growing!

It is FX that is in danger of becoming obsolete and dying out, and the investments into FX equipment are all at risk. All it takes is further DX sensor improvements so that FX offers even less than it does now, and eventually even the FX fans will realise that they have recklessly bought into an obsolete system. A system that has a premium price, is heavier and bigger, and in quite a few ways already inferior to DX.

Of course there are some serious photographers who have a real need for FX. But they are a tiny proportion.

To all those thinking of buying a D700, please think more about it first! How will you feel when you realise that your old D300 was BETTER in many ways? How much money are you going to regret spending?
