Amazing that very few understand that it's hard to compare prices with a camera that is brand new to the market vs. ones that have been on the shelf for months or years.
This cycle will continue. When the D90 has been around for about a year, Nikon will introduce 1 or more entry level cameras below the D90's specs. Then, in comes the herd of guys going, "OMG, why is that so expensive? I'll just buy a D90 instead."

Canon is demonstrating this with the XS now and that's how not to release an entry level camera. I don't see anyone is exciting about the XS.

it's the most clicked camera on dpreview so it must have something going for it.

most likely is because it's still on their front page.

btw dpreview's rating is kinda questionable, majority of them seems to be highly recommanded...

That's because in general, modern DSLRs have continued moving forwards and improved on their predecessors.

DPReview does give numerical scores, they just never display them with any prominence.

they mostly review SLRs, and SLRs for the most part are within a couple % of each other.

when something isn't recommended you know it isn't all that good. like the DP-1. good concept let down by sigma's slow image processing and a slow lens (which is a result of them wanting it to be an ultra compact rather than merely compact)

Sounds great but... what's the maxium shutter speed considering ISO starts at 200?

ISO 200 with 1/4000 is pain in the ass.

That's probably what it is. Hence we buy $100 worth of 3-stop ND filters.

Why is ISO 100 a special value? Are there draw backs to using it?

 

[jpeyton]

"This is a game-changing product"

Nikon's website is down for the addition.

 

[jpeyton]

Yes!!!

FYI, no AF in movie mode. This is good IMO because 1) contrast-detect AF is painfully slow and 2) that's how Hollywood does it. Check out the sample videos on Nikon's D90 microsite. This wasn't possible before without a $1000 SLR lens adapter like the Brevis flip.

720p24 is the HD res.

ISO 100 isn't a special value. As for draw backs, think about using the camera in sunny day especially if you're using a fast lens. Even f/2.8 is fast enough to cause some problems. You'll be forced to step down the aperture even when you don't want to.

Anyway, movie is nothing but great!

 

[jpeyton]

Watch in high quality.

I'm sold. The movie mode is fantastic.

 

[soydios]

Alright. Finally. Looks great.

Now where can I buy one, and when?

Any news about weather sealing?

No weather sealing; it has what Canon calls "tight body lines".

What does that mean? How about how many shots you get at 4.5 FPS RAW?

And GPS isn't built-in? I guess that could be expecting too much.

 

[soydios]

Any word on GP-1 pricing?

I just mean to say, why is it designated as "Lo1" instead of just starting at ISO 100? Seems like ISO 200 is the "default slowest ISO." So I wonder if there's any reason not to use ISO 100.

Base ISO isn't a universal value; it depends on the medium. Just like there are different types of film, each company's sensor has different characteristics.

The base ISO is the value at which the sensor displays the best balance of noise-characteristics and dynamic-range. For the 12.3MP CMOS in the D90/D300, that happens to be at ISO 200. At ISO 100, you give up a little dynamic range for lower sensitivity and imperceptibly less noise.

Many people say the bump in base ISO was necessary for Nikon to design a sensor with better high-ISO performance.

Thanks that's exactly what I was looking for. So, which would you do first to lose a stop? Add a neutral density filter or bump the ISO down to 100?

 

[jpeyton]

Drop the ISO if I just wanted to lose a stop.

A couple of different sources on the web are confirming that the D90 will indeed have slightly better noise performance than the D300. Since they share the same sensor, it must be tweaks with the processing that Nikon has made in the year since the D300 came out.

Imaging Resource has D90 images in their Comparometer, and comparing high-ISO samples between the D90 and D300 confirm that the former keeps a small but noticeable amount more detail.
