Some of the best birding/aviation shots I ever took were with a Nikon D70 and a screw driven 80-400mm lens, on the wildlife front, deer were great coz when you focused they looked right at you!

Yep it can Algi and sometimes I feel that all lenses should still be screwdriven, noisey but it always seemed to work?Can't the ROM be hacked on these to make them screwdrive?

I've had 3 Pentax DA16-50 lenses, all 3 have had focus issues even after a full sevice with board and motor replacement, in comparison the Tokina screw drive version has never ever let me down in another marquee.
On a side note, the D500 is no more buggy that any other camera but the AF is.... well....pretty awsome

I've had DA* zoom lenses for almost ten years and they have been used extensively so when the SDM packs up (twice with the 50-135mm and now the 16-50mm is playing up) and Johnsons fix them quickly and efficiently I put it down to wear and tear, cough up and get on with it. Paying for the repair is a lot cheaper than buying new lenses.
But I do wonder about converting to screw drive auto focus. I recently used my Sigma 10-20mm for the first time in ages and it snapped into focus on the K5 in a split second.
Does anyone know if Johnson's do retro conversion to screw drive?

Better than running after a building with a MF tilt shift lens and the sun setting fast
I wonder how many mountains, hills, trees and forests have run or flown away from jules
