D90 to D7000 my findings

Let's do the math ...

16-12 = 4
10-6 = 4

You say that 4 "is quite a lot less than" 4 ...

Kim,

I think Barry meant this:

Going from 6 MP to 10 MP is approximately 66% increase in resolution.
Going from 12 MP to 16 MP is approximately 33% increase in resolution.

66% > 33%

You have a valid point...but I would note that both jumps are indeed significant regards results. The jump from 6 to 10 was more noticeable in terms of resolution. The Jump from 12 to 16 seemed to have a much more noticeable impact on Focus Techniques that where additionally made critical by the increased AF system sophistication. I would not consider either jump...insignificant as some here have alluded to.

I was entirely aware of what he meant ... he speaks with great ambiguity and much hand waving ... and then insults everyone around him.

That was my point ...

I never made the 6 to 10 jump ... going from 6 to 12 instead. Big jump. Sharpness took a while to return.

12 to 16 was also a big jump ... sharpness also suffered, and for the same reason. But the jump to 16 also brought with it very fine grained noise and that made more difference than anything ...

It's going to take you about a month to get used to the different settings, button layout and the way the sensor and Expeed processor renders images.

I have owned D70, D90 and D3200 and all of them were VERY different in the way they operated and the images they produced.

Also don't use auto anything.

Glad someone gets it!

I personally don't see 12 to 16mp as that much of a jump, and def not enough to get blamed for out of focus shots either.

Whilst I'm here I don't have a problem with the D7k WB either..most cameras need some tweaking, green/magenta hues can cause problems with skin tones. Same for most cameras..though the D7k is quite decent here, at least in my view

Metering again it's not a big one..but worth a discussion there are some flaws in Nikon's metering, but not enough to get worked up about as some folks have

AF that's the big one..I know someone who went through 4 D7000's to get a good one..and only one was nearly there..looking at their shots the other 3 were well off.

Looking to do a thread on the subject but thought this would be a good place to get feedback

It's been noted that D7000 focus point bias is an issue with Matrix Metering. I have tried to point out that it's true and something to understand. It's also something very controllable and I wanted to point out settings that affect it. Here are examples taken from a larger series done to confirm consistency. Each sample is accurately representative. All taken in manual exposure mode with Auto-ISO "on" to show the effect on exposure with with ISO change. Tripod used and focus point set to point left of the central array. The focus point is the thin white line. Center of the frame is the larger black vs white border (focus point placed there gave different resulting exposure....hence focus point bias). Not crops and all full EXIF

Focus Mode affects focus point bias....note the consistent change in ISO with only a change in Focus Mode. (AF-S vs AF-C)









AF-Area mode affects focus point bias...note the consistent change in ISO with only a change in AF-Area mode (9pt vs Single)









Feedback welcome as my goal is to explain focus point bias and how it can be controlled. I would note that the effect is less pronounced than in the D90.

Interesting series of tests...but does deserve it's own thread rather than buried in this one.

I do agree and this thread seems a great place to get a bit of feed back to improve before I go final. I was also hoping to use it to give Barry some honest examples of what I meant with "control" of it and how delving a bit deeper gets you more "control" of the camera. A few things I think he simply hasn't had time to explore more fully and will come with time.

Thank you for the take

I recently just purchased the D7000 along with the 18-200mm and 50MM 1.4 lens.

Here are a couple of my first few shots before various camera adjustments. As a beginner, I think I am going to learn alot with this gem!

A very nice dog. Unfortunately, pic two is a clean miss and will provide ammunition for the focus filberts. Shooting at f1.8 can be hazardous to your sanity. You need to check the eyes for focus and make sure the one you want is sharp before you put them up :^)

This shot shows me you are indeed a good match for that camera. Keep an open mind and take 100 pics for every forum post. Good Luck!

I generally agree with the OP's findings.

The skin tone and color in general is a tad behind other bodies, both FX and DX

The AF has problems with smaller subjects.

The metering is ok, but different than expected. This may be tied to AFS AF mode where the metering is biased more heavily by whatever is under the active sensor. I use AF-C for most of my shooting so I did not see it as much as others.

The white balance is mostly better than some previous DX cameras, but far below D300s and D700 bodies.

In the end, I sold the camera. In hindsight, I should have either kept my D90 or upgraded to the D300s.

Thanks for the info. However, I just moved up from an Olympus c4000 that I purchased in June of 2002,(3.9mp). I have alot to learn!

Having sold both the D300 and D700 in favour of the D7000 I can unequivocally say that everything you write is wrong

It's ok because Nikon will have to pay for the repairs and I'm sure the 3 returned D90's will end up in the refurb basket.

Get it right or I send products back.
Or we could be in complete denial and suffer with bad AF cameras ;-)
