Manual focus vs Auto focus
Why would one want a manual focus lens instead of an auto focus one?
I like using fast glass but do not have a huge budget.
I have a 300 f2.8
plus a few others...all manual focus for my Pentax cameras...on a k100d they are all stabilized as well. I have a three auto focus zooms (one of which is rubbish) and a few other manual zooms.
How much would that lot cost for auto focus lenses? (if they where available to me anyway).
OH and I also have a magic little gadget that lets me auto focus all those lenses as well (with a 1.7x increase in focal length and decrease in aperture....that gives me a 510mm af stabilized 4.8 lens (how much would THAT cost as a lens by itself?)
My entire kit costs less than a single lens to cover just one of the longer focal lengths that I have.
I like using manual focus sometimes..amnd in really low light sometimes it is a must.
