Starting to think buying this lens (Nikkor 28-70mm 2.8) second hand may have been a mistake.
Went out for a walk in the hills today to test it out in the field. Have discoverd there seems to be a problem with autofocusing on distant objects when it's set at the wide end (28mm). The AF is flawless when objects are near eg within 10m, but if I set it to wide and try to focus on distant objects eg over 50m or so away, the autofocus has trouble 'locking on'. I seems to only be apparent when at 28mm too, if you zoom in a tiny bit it seems to be ok
Does anyone have experience of this? Is it faulty? Is it a known issue with this lens?. I really don't want to have to go through sending it back (bought it second hand from MPB photographic) as I've had it just over 7 days so it will have to go away for repair under warrenty I presume? If it needs repairing....
P.S. I've tested it on 2 bodies (D3 and D200) so I'm pretty sure it's the lens itself. My Nikkor 18-70 has no such problem either.
