Your question would require thousands of pages to answer here so I encourage you to ask your teachers. The short answer for why people use Leica and Hasselblad is that both photographic systems represent the highest achievement of human optical and mechanical engineering.
I have owned and used both systems since 1964. They have never failed to work and have never been to a repair center. These products are the tools of purists who generally know more about the photographic process than everyone else. We do not need the assistance of autofocus, electronic apature or shutters, are able to advance film ourselves, and know what light is, what it does and how to control the physics of exposure. These cameras are entirely manuel and there is no need for a battery of any kind. In most cases, the users of these camera systems are smarter than the computers that control the modern digital camera. We don't have to ask a machine what to do - we tell the machine and if we give it the proper information it will do exactly what we have told it we wanted done.
Here is an analogy. The world today uses computers for almost every human task. Computers can solve, using information that someone else has programed into them, most any equation without the computer user knowing anything about how to solve the problem. However, when the electricity goes off, most computer users become complete idiots because they don't know what to do. I use a computer without apology but when the power goes off I can still solve virtually any mathamatical equation using a "slide rule" and a standard index of formulary; a device that I would guess you have never heard of. (That is not an insult but rather a difference in our generations.)
Modern military aircraft cannot fly without their computers and GPS systems, no matter how good the pilot is. I can fly anywhere I want to go using antique navigation maps and coordinates though I might run out of gas before I get there.
Ask you teachers and they will both tell you and show you what you want to know. I was a teacher of economics and law and was always excited when a student took the extra step of asking questions about things I had not covered in class. I taught what they needed to know to pass the course, I did not teach everything I knew.
I hope I have given you an answer to help you start getting the answers you want. In the mean time learn to use the tools you have, master them, and your photography can become a success. You do not have to know as much as your teachers do to become an accomplished photographer....Show more →
While I do agree with you on the purity of using a fully manual camera and have lots of respect for your attitude, I'd like to point out that there's a huge class of problems that don't have analytic solutions and cannot realistically be solved without the aid of computers.
For example, here's one - you have a spherically symmetric harmonic oscillator Hamiltonian. There is a perturbation of the form a*e^(-b*r^2). Calculate the energies of a given level N.
This one is actually pretty simple to do by hand for low N because the degeneracies don't lift much. The N=0 & 1 levels just get perturbed, the N=2 & 3 levels split into two while the N=4 & 5 level split in 3 and so on. The matrices are easy to diagonalize by hand.
The same is definitely not true for cutting edge work being done on stuff like protein folding or large scale structure evolution which is the physics of today. No physicist would want to solve a problem using a computer if it were feasible to do the same calculation by hand - it's not healthy for the ego. ;-)

You've been shooting since 1964 and you still can't spell aperture
