D90 owners: Focus or soft pic issue? must see this

FOUND the issue !!! the UV filter is affecting Focus on the D90

set up

Mr turtle 50 away
300 F4 AFS
AF-C
dynamic area
UV filter ON
CW meter
ISO 400
mirror lock up (delay mode for the D90)
tripod
5 second delay timer with 3 shots
Low speed FPS on 3
Focus put to nearest setting and re-focused for every round of shots

1/800 @ F4 (100% crop) best of the 3 (was hard to choose)
note in NX2 there is NO focus indicater BUT the light was saying its in focus.

same set up second round to verify

1/500 @ f4
note Focus point shows up in the NX this time

[B][SIZE=4]REMOVED UV FILTER [ SIZE][ B]

1/640 @ F4 focus point in NX2 did show

:eek::eek: !! first try, did this a second time to verify it nailed the focus again

S&G note
my D40 did not do this all pics where the same :eek: :confused:
