Why would Ansel (or anyone ) need autofocus to capture Moonrise, Hernandez? Also, he didn't shoot many animals, right?
As even Ben mentioned, Nobody here has anything against manual focus. If we were to be swayed by latest-but useless technology and number games, we wouldn't be shooting Pentax, right?
Don't we still use MF for macro work? MF and AF both have their pros annd cons..Sometimes the MF is desired even for bird photography if the bird is in bush or a nest between lots of intruding branches..Ability to achieve superb manual focus was, among other things, the reason for me to buy a DSLR over a Prosumer..
That said, its just plain difficult and time consuming to focus manually if shooting passerines esp Muscicapidae in action..or BIF of course, unless u prefocus on the most obvious direction the bird would choose to take off..
The 'patience' I mentioned wasn't about using the lens, but about the extra time you have to shoot in order to cover up for the missed shots due to lack of AF..I'm sorry as I should have explained it more clearly..As I reread my reply, it does appear that i was talking about the 'patience with the lens'..
And generally, photographers across world would tend to agree that there are few things more than the 150km/hr crash that one acn't capture with a MF..that said, one can still capture the 150km/hr crash using MF if its a planned one ;)
If somebody offered me a MF100/2.8 macro and FDA 100/2.8 macro, I'll choose the MF 100/2.8 coz it would be cheaper and won't make a difference to my work. :D
However, if somebody offers me k300/4 and a DA*300/4, I'll go for the K300/4 only if I can't afford the DA*..:ugh:
Rainer asked us a question, I replied what I thought would be good for him, as he hadn't mentioend specific use. But clearly my advice wasn't good for him as he doesn't mind focusing manually and insisted on primes. If he had mentioned he didnt want zoom, I wouldn't have suggested him that one..
Anyways, the K300/4 prime which somebody discouraged him to buy is , in my humble opinion,has the best price/output ratio for any 300mm lens in the Pentax system..:D I wnet for it instead of the 70-300 AF zooms coz it was faster than them and had the ability to work with a TC..I simply needed the longest and the fastest lens I could afford..And I also chose it for all the pros that Zewrak mentioned like the built quality, optical quality etc..:p

I don't have much experience in photography, but I do firmly believe that used manual lenses should be bought only if one knows exactly what specification lens he should buy and that lens is either unavailable(out of stock or nonexistant) or too expensive..
If you are not into birds and sports photography, then why do you want a 300mm prime? Why not go for the 70-300mm cheap but good value-for-money zooms? They are meter properly, autofocus and are lightweight too..
I'm not dismissing the usefulness and quality of the old lenses. Infact they are very good, but only if you have specific use in mind and patience to deal with them..
