Actually, I'm pretty flexible when it comes to how lenses and systems behave. A lens with its unique flaws and look is equally valuable for me as a razor-sharp ultra high-fidelity lens.

All boils down what you want to achieve and what emotion you're trying to create with your photography. Film emulation has gone a long way, but emulating glass is not possible the same way (since you don't have any information about what happened to your photons in their way to your sensor), and lenses are important part of the equation, and will forever be, I think.

finally, someone that gets it! these different lenses are all just tools. using the right tool for the job is part of being good at your job.
