I've had the same problem with this lens: couldn't focus properly when pointing the lens up or down. Got repaired two weeks before warranty ends. They sent me the list of changed parts and the price I'd payed - 640 euros. Crazy
Due to a local internal systems error, the incorrect RRPs on the D800, D800E and D4 products were communicated in the UK and Irish markets at the time of announcement. The correct RRPs for the products should have been D4: £5289.99, D800: £2,599.99 and D800E: £2,899.99. We would like to apologies sincerely to our customers for this unfortunate mistake, which has been corrected with immediate effect. We know that there has been strong consumer interest in these products and a high level of pre-orders placed with retailers; Nikon will be honoring the original prices to retailers on all customer pre-orders placed before March 24th 2012.
