Maybe I need to start setting aside some money for a future Lasik
procedure. I truly dread the day when my eyeballs finally betray me.
(Not that they haven't before, but it usually only happens around
closing time.)

What Bruce said. Forty years ago I could manual focus any lens, every time. I
could even pull focus on a car moving toward me. But eyes wear out faster than
old manual lenses. I had a heck of a time focusing the 400 yesterday,
particularly when working from my knees with the camera on a low tripod. Manual
focus is largely in my past.

your head. That's part of my issue and why I don't do much successful
manual focussing. I'd be in trouble without AF.

This is one of the reasons I like my prime SMCK MF lenses.
Nothing tricky to go wrong, still going strong after 35 yrs.
Sorry to hear your having problems with your newish lens...

Subject: DA* 60-250 to C.R.I.S.
The SDM motor of my workhorse lens seems to have failed after what must be
about 20,000 frames. Not too bad, although I guess it shouldn't ever fail on
an expensive lens that is marketed as a premium product. A few weeks back I
started getting intermittent focus failures. Unmounting the lens and turning
the focus barrel manually would wake it up again. I had a couple
assignments, so I held onto it, figuring I'd send it out when the weather
started to get bad. But at yesterday's shoot it failed completely. Couldn't
get a shot off. That was inconvenient as hell, since I didn't have another
lens between 135 and 400, and the Mopar Action editor likes the look I get
in the 200 to 250 range. But I made do with the 50-135 and the A 400. That
400 is getting harder to focus as my eyes age, so I shot numerous frames of
each shot, refocusing after every couple. Should have hung onto the DA
50-200 as a spare, but I sold it to help cover the cost of the DA* lens.
In any case, I hope C.R.I.S. has the part. Don't want to go through the kind
of ordeal that accompanied my K-5 repair in July.
