In case you don't know the D90 is made of plastic and the D300 of magnesium alloy. There is NO comparison to that. Everyone I know who has the D300 loves the " 3 Kings" button. I think it is in a great position. I guess if you are a point and shooter you wouldn't need it. You would wish it had the amateurish scene modes like the D90 has in its place.
I suggest you sell your prosumer D300 and get the D90 if you don't take advantage of the D300 advantages. PM me and if your is in good condition we can do a trade. The scene modes are nice for point and shoot shooters.
Thanks for assuming a lot about my ability.
Apparently, I can't prefer some things from a lower-end camera because it means I have no idea what I'm doing. Besides, I have never used a scene mode before in my entire life, p&s or DSLR. What am I going to do with that dial?
But thanks for suggesting that I sell my D300 for a D90, possibly for the one you have. I'm sure
I'd benefit greatly from such a transaction.
And yes, I realized that the D300 has a magnesium alloy shell. I have picked up my own camera before. However, not all plastics are the same, and some of today's plastics are as strong as metals, if not stronger. Besides, even if Nikon could reduce the weight of their premium products a bit more, they'd have little to gain from doing so. The main reason they don't really feel the need is because "weight" is used as a form of subconscious-level marketing, where heavier things are often seen as sturdier and well constructed even if it isn't. Apparently it works on people.
They'll believe that this is why the D300 costs so much more than a D90, because on paper, they can't justify the additional $500 of the D300 (or whatever the difference is) based on specs alone. In reality, the D300 is better not because it's sturdier, but for a lot of small reasons with regards to it customizability, and the quality of the AF points available. It's not just about the number of AF points.
Even if the D90 was out, I would have still bought the D300 because it's still a better camera, and I use the 51 AF points in various situations. I said I don't use 51 points in general shooting, that's all. I had to shoot a concert after coming back from my 4 week trip to Japan, and I doubt I would have been able to focus in darkness as well as I could have with a D90.
My D300 has 15 cross-type AF points. The D90 doesn't.
However, for the OP, there isn't a lot better about the D300 unless he needs the AF points, continuous burst rate, and all the customizable configurations and memory when shooting JPEGs.
If I was someone looking to buy a camera or lenses this is the last place I would look for advice. Go to a dedicated Nikon, Canon, camera, etc. forum. There are plenty out there. Almost all professional sites....
So jaseone's link to NikonCafé wasn't professional enough? NikonCafé is one of the PREMIERE Nikon websites.
