Hi all. I've had the original Canon 5D for 8 or so years now, and while it's served me well, it's time for an upgrade. I was originally looking at a possible 6D + 7D combo to cover both landscape and wildlife/amateur-sports. Unfortunately, most of my canon lenses have wound up with fungus in them, so I will be needed new lenses as well. So I figured there's nothing specifically tying me to Canon any more (other than the $500 or so 85mm f1.8 that is absolutely fantastic and fungus free). To be honest, I initially ignored looking at the Nikon D800(E), due to it's insane megapixel count, assuming it would gain little once noise is factored into the equation. Well, it seems I was wrong and it does display genuine resolution increases and good noise handling. What particularly attracted me to it was the ability to swap between Fx and Dx mode. In a sense, I have both a landscape and a sports camera in one. It's also cheaper than getting the two Canons. And while it's not a professional sports option, probably, it's going to be well good enough for the amateur stuff I want to do. Anyway, that was my decision process at arriving at the D800.
So my question is relating to the standard pro zoom ranges (i.e. 24-70mm and 70-200mm). I really know very little about Nikon lenses. With the Canons there is the "L" designation, and I knew very well the reputation of the 70-200 f2.8. What am I looking at in Nikon? Is there a pro-series lens designation? Are some renowned as better than others? While I was going the Canon route, to save money I was looking at utilising a Tamron for the 24-70 instead of the Canon (or alternatively the Tamron instead of the 70-200; which had the bonus that it wasn't bloody bright white!). Any thoughts on image and build quality in these two zoom ranges for the Tamron vs the Nikon (and perhaps Sigma and Tokina if they are up to class)? Another possible investment will be a 1.4x teleconverter. It seemed with Canon system that canon was probably well ahead of Tamron in that regard. What's the state of play in the Nikon system?
Finally, any other thoughts or hidden issues I need to know about swapping systems? I very rarely used the canon DPP software, and used Lightroom and Photoshop for most of my processing work. I assume I will probably not bother again with the Nikon proprietary software, unless it is unusually good.
Cheers all.
