Most people now use auto focus cameras. My old medium format Hasselblad is a V series so is manual focus as is my large format camera.
Also one of my favourite 35mm wide angles is manual focus, but thanks to Nikon keeping there F mount it still works even on the latest modern Autofocus cameras.
What I have found surprising is that sales of classic manual focus lens is increasing. The reason is cameras like the micro four thirds system and the Sony Nex system. People are rediscovering some of these old classic lens and with converters and features like focus peaking they work well on a number of modern cameras.
It’s great to see these old lens being used again.
