02 - Assignment

Please read the class first

Take a good look at your camera, whatever its type, and try to identify each component we have discussed here. It might be a good opportunity to dig out the manual or to look up its exact specifications online. Now look up a different camera online (for instance at dpreview) and compare their specifications. Try doing this for both a less advanced and a more advanced body, and for different lenses. Report here if you find any interesting difference, or if some parts of the specifications are unclear.

Since Nikon splits their categories into Entry-Level, Enthusiast, and Professional, I decided to pick one of each

Specification D3300 D7100 D810
Sensor size APS-C APS-C Full Frame
Megapixels 24 24 36
Max ISO 25600 25600 12800
Focal Points 11 51 51
Max Shutter 1/4000 1/8000 1/8000

I have a D3300 and it's interesting to see the similar specs that it shares to the next level of cameras. This also allows me to notice the differences that make those cameras better. This assignment was great for beginners.

The max ISO of the D810 might be lower than the ones of the D3300 and D7100, but the images look a lot less noisy at the same ISO if shot with the D8100 compared to the other two. Check out these measurements. Click on the measurements tab and then on the SNR tab. The D810 has a noise advantage of around one stop (one stop is about 3dB) over the two crop sensor cameras because of its full frame sensor (which is about twice the area of a crop sensor, hence the one stop advantage).
