HI guys. I'm considering investing in a D600 (used) or new D610, too either complement or replace fully my D800. Whilst the D800 is a superb optical machine, apart from a few dedicated landscape missions, I very rarely get the use out of all those mega pixels. I know the D600(610) is smaller, lighter, uses the same battery as the 800, but do have a few questions please. For those that may have switched or run the dual camera system, could you give me your thoughts on the following please ?
1. Not having a dedicated 100% zoom function. I used this all the time on my D800 (and on my now sold D700 and D3s), and whilst it may seem minor, does this lack of a feature generate any real frustration or do you just get used to it ?
2. The well publicised dust issue. I'm sure it's not quite as bad as you read on the internet, but obviously bad enough for Nikon to do a U turn on this. So the question is, does this affect the majority of D600's or a relatively small percentage ? Is there a point where the dust (oil splatter) just ceases ? Are the newer D610's completely free of this ? Obviously getting dust on a sensor is part and parcel of owning a DSLR and changing lenses, but is it much more than say I would have had with the D3s and D800 for instance ?
3. There's been a lot of talk about the AF system, so 2 questions really. Is the AF array coverage really that much smaller and really noticeable from the 51 point AF system in it's bigger brothers, and how good (or bad) is the system when the light starts to fade. Does it hunt quite badly or miss focus completely ?
4. Although the eyepiece is different from the pro models (square not round), I am lead to believe that the actual view and magnification is the same as the pro models. Is that correct ?
5. Are there any other major differences from the D800 (other than MP, file size and pro build and button layout) that I might miss ?
Sorry for so many questions, and thanks in advance.
