Jack, as requested :
Lose the 1st para, it doesn't even mention the D300 (i.e. it's waffle)
2nd para, good. Needs an extra Return at the end (to separate it from the 3rd para.)
3rd para, useful info.
4th para, I had to read several times before I understood what you were saying.
5th para, very useful.
6th para (The settings...), good, except are you sure that everyone who reads your review will know who 'Ken' is? Best to give references in full if you're going to use them at all.
7th para (The other...), very good.
8th para (The autofocus...), useful info.
9th para (Active D-Lighting...), good.
10th para (The availability..), good.
11th para (The colour...), useful.
12th para (I don't really...), I'd leave out the 2nd sentence, since you are writing the review as an amateur, not as a pro.
Overall, very good Jack. A bit of waffle, but not too bad. You included a lot of useful information, some of which I did not already know, so I do feel that your review was helpful to read, even if it was very long
I charge extra for spelling + grammar corrections
