Okay the blue dot is normal i guess.

Here the answer, can share with 50mm 1.8D owner
Is this a 50mm/1.8D lens?
If it is, then that bluish circle is normal. The coating on the rear element of that lens is not made for digital photography. In some cases, light will thus be reflected from the sensor to the rear element and back to the sensor.
You have shown us photographic proof of this phenomenon.

Both the older 50mm F1.8 and f1.4 lens have this blue center spot when shot stopped down. Often worse on a bright but overcast day as this flare can occur regardless of direction of the sun on those days. On sunny days usually requires sun to hit the front of the lens. Only happens stopped down. I see you shot this at f16. Shoot at f8 or wider and you shouldn't see it.

The blue circular pattern is reflection from your image sensor. The sensor is like a mirror and when the shutter opens all the light entering the lens is reflected back again. I can see that you have used the 50/1.8 at f/16 which makes the problem worse. The more you stop down the more visible that reflection becomes. This is one reason why some lenses get new nano coatings on the rear element, to avoid that reflection.

D7000 beats D300s in term of IQ. D300s old technology d.

Siapa mau pergi shooting tomoro or sunday?

Okat, let me share some experiences with you

Why D300s over D7000
1. Faster FPS - 7 .
2. More focus points - 51 points (15 cross-type sensor) p/s: D7000 only 9 cross-type sensor
3. Built Quality better than D7000 - Weather and Dust Resistant.
4. AF-On is seperate with AE-L/AF-L
5. Can switch AF-C,AF-S,M faster.
6. Can switch Auto Area, Dynamic , Single point faster
6. Semi-Pro Category.
7. Dual Card Slots CF+SDHC( Allow you to using CF card mean faster) p/s: D7000 also got dual card slow but SDHC only

Why D7000 over D300s
1. Better sensor 16.2MP
2. ISO 100 - ISO 6400 - p/s: D300s ISO 200- ISO 3200
3. New EXPEED 2 Processor
4. New TTL exposure metering with 2016-pixel RGB sensor
5. White balance more accurate
6. Better video recording


Conclusion

Grab D7000 cannot make you get GOOD,SHARP,GENG,GORGEOUS IMAGE, bear in mind.
Alot people using D300s also can make good pic.
Khaled Hassan just use D200+28mm f2.8d , he able to get good shots, make wonder. Won alot awards.
Camera is a tool, how to use the tool well is depend on you.

So is your brother choices.

Anyway google got alot comparisons, why not you try to put some effort in searching instead of just straight asking here. But you ask here, we all still will share with you lar =) because you can get more infos from website.

Hmm, i suggest you try to call several shops to check price.
