For a long while I have wanted to compare my D7000 with a D90, and as I am in the process of producing a simple photography elearning package to explain Aperture, Shutter Speed and ISO, it seemed like the ideal opportunity to compare them side by side for quality and noise handling at extreme iso.

The D90, a classic and fantastic camera since 2008. Used with my 17-55mm f2.8 portrait lens.

The Fujifilm X30

The Fujifilm X30 (2014) a capable and portable camera which you can take full manual control of.

Recently I have brought an Fuji X30 to be my always carry camera, so thought I’d add that in too…

I could list all of the stats and specs, but if you want that in-depth number crunching check out the great reviews on dpreview..




Starting with ISO the photos I have taken are really quite revealing…

Comparing the ISO handling of the D90, a lot of digital grain comes in at 3200 (top left) compare to ISO 400 (bottom right)

The D90 really takes an excellent picture, but it’s ISO quality when you ramp it up to the top of it’s numbered range is pretty bad, the digital grain is very present and I would find this unacceptable, even at 1600 the grain is too obvious.

The D7000 has fantastic control of grain, even at 3200 the resulting image is acceptable to use, the only problem with this image is I have got the focus slightly wrong, but there’s not a dot of grain to bother the image… very impressive. I used both lenses just in case it made any difference as I used the 50mm on the D90.

The X30 did surprisingly well too (even with it’s smaller sensor), although it has handled the grain in a different way, it seems somehow smoother, perhaps more blurry at the 3200 end, which isn’t too bad a thing.

On this occasion the D7000 has it on ISO and this from a camera that’s 5 years old, I remember when I bought it I tested it’s ISO against my other work camera, the Canon 5D and it excelled at low light performance in those tests too…

I would be very interested to check out the new D7200 alongside these cameras, but my budget only goes so far!

All of these images are straight jpegs from the camera with no alteration, and no in camera enhancement, put into photoshop so I can compare them directly side by side.

I will be using these sets of images to explain ISO in an elearning package I’m putting together for my students currently, it takes a bit of time to setup, but will be well worth it..

Next comes the Aperture control… but that’s for another post!
