As you see in the list on the left the sigma lens has a focal length of 30mm, but because the detector in the camera body is smaller than the 35mm film the lens is built to expect, it has an effective focal length of 48mm (like a zoom of 1.6x of a normal, zoomed all-the-way-out film or digital camera). The Sigma lens is also a fixed lens (no zoom), which supposedly means it is way higher quality - and supposedly beginner photographers use zoom inappropriately where they should probably walk toward or away from subjects for the better picture.
So I have a lot to learn!
Not every post will be this boring, I promise. I'm just getting the technicalities out of the way because after all, it is all stuff I just learned and this IS my "camera's blog."
Sample pictures ahoy!:
See here there wasn't anything to take a picture of when I unpacked, except for other things that I unpacked...
This picture is significant because it was really dark in this room and my aperture was wide open, and this lens has a big aperture, so the picture turned out crisp.
Now I was just showing off.
