Hi all. Hope I have posted this in the right section. I openly admit to being an AF man, its what I'm used to and it fits with what I do, but, maybe I'm not getting the "whole picture", so to speak, and perhaps I am limiting myself. I'm thinking perhaps I should explore MF, its obviously very popular around these parts! So, what lenses do I look for? Whats worth buying? Which mounts/adapters? Some information that will be useful:- The lens range I use most these days are 19, 23/24, 30/35, 50/60 (APS C) All of my output goes to stock agencies, IQ is paramount, corner to corner, edge to edge. I habitually shoot at 5.6/8, although sometimes I like to limit the DOF for some selective focus shots. Subjects covered, pretty much everything, like all stock shooters. Generally, I don't shoot wide, rather, I pick out details in a subject, for example, instead of photographing a whole door, I will pick out the letter box, the door knocker, the door bell button. Architecture, detailed buildings, the 23mm on the X100 and the Sigma 19 and 30 on my 5N do this well, as do the 35 and 60 on the X PRO 1. The above mentioned lenses do a really good job, AF is not particularly fast, but then my subjects don't move. So, am I missing out, are there some MF lenses that will "better" what I am using currently? I don't intend to spend a lot of money pursuing this quest so Leica glass is out of the question, at the moment anyway. Any and all thoughts and suggestions welcome. Rich.
