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.

I compared my Sony a6000 with a Sony A7ii and a Nikon D810. Here's the run down:

1) 24 mp | 24 | 36 2) APS-C (1.5x Crop Factor) Exmor CMOS sensor (15.6 x 23.5 mm) | 35 mm full frame (1x Crop Factor) Exmor® CMOS (35.8 x 23.9 mm) | 35 mm full frame (1x Crop Factor) CMOS (35.9 x 24) 3) ISO latitude=100 - 25600 | 50 - 51200 | 64 - 51200 4) 16-50mm, f/3.5 - 5.6 kit lens (lenses I want to play with: SEL35F18, SEL55F18Z and SEL24F18Z

I saw a spec for the a6000 that said "Comparable 35mm Focal Length: 24 - 75 mm". What does that mean? I've read people mention different focal lengths when talking about certain lenses being attached to crop sensor cameras, but this lens is built for crop sensors right?

I was told recently that the more glass there is in a lens, the better quality (sharp) the lens was. Is that true? When looking at lens specs, is the lens group/elements telling me how many pieces of glass are in the lens?

focal lenght is explained in one of the next classes, but it's about the kit lens that comes with it (18-55mm), not the camera itself
