Is the fujifilm mkx 18 55mm t2 9 hard to focus manually?
The site doesn't rate how hard this lens is to focus by hand, but its design tells you a lot. The Fujifilm MKX 18-55mm T2.9 is a manual-focus cinema zoom with geared rings, built for smooth, precise focus pulling in video work. It has no autofocus, so you'll focus every shot yourself.
On Fujifilm X bodies, f/2.9 gives about the depth of field of f/4.3, so small focus misses matter a little less than they would on a fast prime. If you're used to autofocus, expect a slower, more deliberate shooting style. For more on manual-focus lenses in general, see Lenses.
