D7100 - High ISO test and other Pictures (interesting)
6

Today I held the camera in my hands. I managed to sneak my card in it and take some test shots. I did it without knowledge of the Nikon personnel and if they will have some problems because of it, I am really sorry. I did it without their permission and awareness.

I really like this camera. Images are really sharp and crisp.

This is a pre-production camera and does not have the final firmware in it. There are some unmapped dead pixels in the image.

I have no idea what Image settings were used.

Lenses used:

Bag: 14-24 f2.8

Cameras: 50mm f1.4

Sensors: Micro 105mm

TO DPREVIEW: I had to resize the 6000 pix files to 5476 so that they fit the 20 MP limit. This is kind of lame isnt it? I wanted to add original untouched files and I could not.

Some images are slightly motion blurred. Missing images were so blurred that there is no point in showing them.



Bag - whole image.



Crop - ISO 200



Crop - ISO 400



Crop - ISO 800



Crop - ISO 1600



Crop - ISO 3200



Crop - ISO 6400



Crop - ISO 12800

Crop: ISO 25600



Cameras - whole image ISO 3200



Crop - ISO 3200



Crop - ISO 6400



Crop - ISO 12800



Crop - ISO 25600

Here is the interesting stuff - sensors. FX, DX, CX and compact cameras.



ISO 100



ISO 400



ISO 1000



DX and CX side by side - ISO 1000.



CX - ISO 1000

Notice the AF on chip lines.

I hope you will like these pictures.

Nice - thanks.  

Any chance that you can allow 1:1 viewing on your gallery?

Very impressive, sneaky work :). I can't really get a reliable impression from looking at these on my phone (will look again later). So what's your impression of the ISO capabilities? And do you know if these are with noise reduction on?

It should work now.

Thanks -

In spite of the shake, it still gives me some idea about noise.  I love my D300, but not at 800 or above.

ISO 6400 looks fine to me. ISO 3200 is really nice.

The images look like the NR was low or off. It really was a preproduction camera - in the exif it is called Q0760 and firmware is 0.22. Final production cameras will probably look even better.

Main reason why I've pre-ordered a D7100 is ISO performance or lack thereof of my D300s. Other reasons are: having the ability to crop the 24MP image, F8 AF, additional 1.3 crop factor for birding.

OP: Thanks for the ISO examples. Definitely a vast improvement over D300s, D7000 owners will no doubt see an improvement but not as much as D300 owners will.

Really impressive. Also a relief to see no moire effect due to the absence of the OLPF filter on which some people had some initial reservations.

Regaring the Low pass filter

I would expect it to be a complete non-issue,

In order for image details to alias they would have to be smaller than half of a single pixel, a 24mp DX sensor that is pretty darn small, I expect that lens resolution in all practical cases to be a sufficient low pass filter.

Moire is a function of the pixel pitch, pattern pitch of the subject, focal lenght and subject distance. Unfortunatelly, that we see no moire on this bag does not imply, that we will never see it on anything. I might have zoomed out or/and stepped few steps back, and it could appear. Or not - if nikon implemented some clever software moire elimination.

Re: D7100 - High ISO test and other Pictures (interesting)

Well, these are certainly impressive noise wise, even though the light is good on these shots.  I'll reserve judgement on the camera, though, until I see something more official.

Re: D7100 - High ISO test and other Pictures (interesting)

High ISO jpegs suck as usual with Nikon. I'm sure in RAW this will be better than D7000 but not by much. I hope to see better DR at ISO 1600/3200, that can be improved a lot Over previous generation.

My hi iso jpgs from my D7k do NOT suck...but are quite good.  This cam seems even better. It's the AF that is suspect...not up to 7D's standard.

Re: D7100 - High ISO test and other Pictures (interesting)

Impressive high ISO, but the truth only comes out when the lighting is low, with highlights mixed with shadows in atleast semi long exposures, with enough light for low iso, even high ISO can look deceivingly good. This can be noticed when post processing the RAW

Wouldn't go higher than 1600 with these

Really? These look quite rough and even 1600 looks suspect. Much gushing about high iso in this thread but these samples but I'm not seeing it. The raw files should be better.

Really??? You must be very hard to please then.

D5200 has the highest ISO APS-C score in DXO mark ever. If D7100 uses the same sensor which lacks one layer of filters compared to D5200 this camera should be really good.

BTW that lower part of the bag is really tough subject - dark and low contrast details.

Nah, way to much chroma noise and blotches  at any NR setting. i have the D5100. I would not shoot it in jpeg at more than ISO 1000, depending on situation. In RAW, I shoot at 3200 without a problem. For jpeg shooters Nikon is not a very good option, look how the 5D Mark III crushes the D600 in jpeg, but on RAW the D600 is noticeably better.

Re: D7100 - High ISO test and other Pictures (interesting)

Thanks.

1) First, that 1000ISPO image (105mm) of the sensor is very nice, at 1/60s. Did you use VR?

2) Given the abscence of AA filter, even if there is some noise in the high ISO images, one may still be able to remove noise while keeping detail (more) intact. This has been reported for the D800E.

3) I like the way the D5200's sensor deals with colors, better than the D7000's. This will be a plus if the sensor is similar.

4) If the buffer of this camera was like 30 RAW, I think the case for a D400 would be very weak. As is, I believe a D400 is coming.

Re: D7100 - High ISO test and other Pictures (interesting)

I think, as we know Nikon, high iso, details, colors, dr, af will be great in the D7100, for sure better than previous generation and the competition.  I only have concerns about banding, as I saw some serious cases with the D5200
