Thx for replying so fast.
Actually I thought thru. I kinda feel 'outdated' shooting with D90. Coz 720p@24fps, plus high noise levels at low light during video mode, regardless of ISO set (I observe digital noise even at ISO 200 shooting video in low light conditions, quite pathetic when it comes to video-editing). And the 11-point AF (+1 crosstype) is seriously unnerving when I slap on my Raynox DCR-250, the D90 just cant seem to find a single AF point! The continued AF hunting really turns me off when I try macro with the Raynox. I'm hoping that D600 with 39-point AF can be much better at this. And the dynamic range - hopefully fellow D90 users can confirm this - but pictures seem to be whited-out in terms of colour tone, hence dynamic range. When I shoot on D90, no matter what kind of lens I use or how expensive the lenses are that are paired with the D90, the colour rendering from the D90 seems to be a shade or two brighter than expected. So I'm banking my hopes on D600 to resolve this - or am I hoping for too much with the D600?
As for pricing wise, no issues with coughing up the money. I'm currently in NUS studying, semester's gonna end soon. Probably gonna find temp jobs to do during the summer break. And if I manage to sell off my D90+18-105mm + supplied accessories for ard 1k, that would mean my nett expenditure is reduced to abt 2k, also taking into account the possibility of price reductions of D600 due to depreciation. So that means abt 2 months of work to upgrade to D600, money no issue here.
And just as u mentioned FX lens is expensive, so I hope i can find the best one lens to cover the wide angle range. Since I have been on DX all the time, I dun noe how wide is wide (18-105mm DX lens at 18mm is only 27mm equivalent for FX). Is 24mm justificably wide enough to take landscape/cityscape shots with the typical barrel distortions that wide-angled shots are famous for? Or do I need to go down to 16-18mm rnage on FX to get that effect?
Dun be surprise to see noise using d600 video mode, especially if u r planning to use 'kit len 24-85'.
Just buy d600 and try it .. different ppl different expectation. Only u can decide if its worth the money spent.
For landscape, go for the new 18-35 , u can go wrong. Personally I would get this wide angle len to start off with. Plus a cheapo afd 50mm or 85mm . . F1.8 ... u are ready to enjoy ur cam. Lastly get a 24-85 if u decide u need a mid range zoom
