Buy the newest DSLR or the old model?
It's been a long while since Nikon announced anything before the D3100
. So with the Nikon D90 finally being replaced, we are seeing something much more robust in the upcoming Nikon D7000. Nikon has tried to be much more careful with their product segmentations without treading on the toes of its other models unlike Canon. Having said that though, I am seeing a much more serious dilemma when choosing between a Nikon D7000 and a Nikon D300S then I would have between a Canon EOS 60D and a 7D. If you are wondering why then you should take a look to see how close the specs are and also where the D7000 proves to be somewhat more superior.Nikon D7000 Specifications
16.2 megapixels APS-C CMOS sensor
HD Movie, 1920x1080 (24fps), 1280x720 (30, 24, 25fps)

Continuous Burst Speed up to 6fps
Dual Memory Slots (2x SD/SDHC/SDXC Cards)
39 focus points AF (including 9 cross-type sensors)

D300S Specifications
12.3 megapixels APS-C CMOS sensor
HD Movie, 1,280 x 720 (24 fps)
Continuous Burst Speed up to 7fps (8fps with MB-D10)
Dual Memory Slots (1x CF, 1x SD/SDHC Cards)
51 focus points AF (including 15 cross-type sensors)
ISO Sensitivity range: ISO 200 to 3200 (Expanded 100 to 6400)
Key Differences
The first thing most people would notice would be the obvious increase in the megapixels count on the sensor. While the increase from 12.3 to 16.2 may not please the crowd asking for 20+ megapixels but what is really worth taking notice of is the ISO range of the D7000. With the increased resolution, Nikon has obviously significantly improved their noise reduction to allow for an even higher ISO setting at ISO 25600 (2-stops more than the Nikon D300S).
The new 39-point AF system in the Nikon D7000 offers us something to look forward to from the 11-point AF previously in the D90. Sure, it's not quite the 51-points AF system of the D300S but if it's quick and accurate enough, you probably won't need so many focus points anyway. More interesting but less clear (at least until we can do more tests) is the new metering system of the D7000. Using a 2,016 pixels sensor instead of the previous 1,005 pixels sensor, it should technically provide more information for more accurate metering. As far as burst speed though, the D300S still holds the trumps with up to 7fps (8fps with MB-D10) as opposed to the slower but still very faster (faster than Canon 60D, we may add) 6fps.
There is also the improved movie recording feature in the D7000. Now shooting Full HD at 1920x1080, the D7000 also benefits from the AF-F focusing mode which allows AF during the video mode. Both cameras are equally rugged with the lighter D7000 providing dual SD card slots as opposed to the CF and SD card slots on the D300S. While CF cards may be more important to some professionals, the convenience of SD/SDHC/SDXC cards is starting to win over many others. This is especially true with the faster and more durable high end cards in the market. Not everyone would agree though and more so if you have lots of expensive CF cards already.
Why Buy Nikon D7000
- Lighter but still very rugged body
- Full HD movie with in video AF
- High ISO range
Why Buy Nikon D300S
- Higher Continuous Burst Speed
- 51-point AF System but not enough to make a difference
- CF card shooting
My choice? Just get the D7000 or if you are not in a hurry, wait for the D300S replacement which will no doubt put the D7000 to shame. Might have to wait until 2011 though
