Manual focus with a proper lens (i.e, a real focus ring, not the crap that's on 95% of AF lenses) is quite enjoyable. Since I have gotten into older, high quality MF primes, I love manually focusing them. I feel a connection with the subject, and it actually improves my photography. I enjoy the process. Also, the fact that I can get L-prime image quality from lenses a fraction of the cost. I do have a split prism focus screen in my 30D, which makes manual focus a lot easier too.
It is actually possible to get L-like quality from many lenses, provided you use those at their sweet spots and know how to process images well enough.
The thing that makes L-primes stand out, is that they actually are usable wide open, and 1/3 of a stop closed are truly excellent. IMO, older lens designs are generally not capable of this feat, although there are a few exceptions (CZ 21 F/2.8 comes to mind).
Apart from that, it also depends on what one prefers. Personally, I really enjoy the look L-primes provide, the contrast, colour, sharpness and bokeh. If somebody else prefers CZ, or Sigma, or Tokina, or Nikon, or Tamron, or whatever, that's great. In the end it is what each of us can or wants to make of a particular combination. And for that, I am really glad we all have a choice, and more than one for that .
Kind regards, Wim
