Focusing is fundamental to the imaging process. Many of us take it for granted that the technology in our AF cameras will get it right, and it usually does, almost regardless of the subject and the lighting conditions. The camera brands have invested a huge amount of resource improving, fine-tuning and innovating how autofocusing works since its beginnings in 1985 with the Minolta 7000. Accuracy, sensitivity, responsiveness and tracking skills have improved beyond all recognition and we should be thankful that autofocus is so incredibly good.
Mirrorless cameras are a comparatively recent phenomenon and it’s true that the AF on this camera type lagged behind DSLRs to begin with, but they have caught up in spectacular fashion. To name a few models, the Canon EOS R3/R5, Fujifilm X-H2S, Nikon Z 9, OM Systems OM-1 and Sony Alpha 1 all boast remarkable AF skills with customisable patterns, eye/face/subject detect with quick and very tenacious focus tracking. What’s more, they are as capable with live view as they are with viewfinder AF. That is not the case with DSLRs, which are generally excellent when the optical viewfinder is being used but are much less effective in live view where they can be slow and uncertain.
Why go manual?
So, having extolled the many virtues of autofocus, you are probably wondering why we’re here suggesting manual focusing. There are several reasons why you should embrace it into your shooting workflow. At the very least, when AF lets you down you will know how to work round the problem.
Every AF camera and lens can be used to focus manually and who knows, you could get to enjoy that element of involvement so much that you invest in a new (or pre-loved) manual focus lens.
The first thing to recognise is that while AF is undoubtedly brilliant, it’s not infallible. An AF camera, even
