I am about to upgrade from D7000 and buy the Nikon D600. I already have some great full frame glass in the Sigma 50 f1.4 and 70-200. However I am also planning to add the Nikon 85 f1.8 and some wideangle glass. I am not a proffessional. I travel and hike a lot and nowadays I mostly use my Panasonic GX1 for that, but when I am at home I prefer my Nikon for events like weddings, parties, concerts, ice hockey games and portraits.
Apart from the glass above I need something with a bit more wideangle and for some events when I am stuck in a seat I feel it is advantageus with a zoom. I don't like the price, size and lack of VR on the Nikon 24-70 so my options are: -The kit lens Nikon 24-85 VR plus Nikon 28 f1.8 -Tamron 24-70 f2.8 VC -Nikon 24-120 f4 VR
These all come at fairly similar prices where I live. I have no bias against third party glass since my Sigmas are simply awesome and I have no doubt that the Tamron can hold its own against the Nikon zooms above but I am interested in other peoples experiences with these lenses.
As I see it the first two lens kit has the advantage of the lenses being more light weight (I never saw the charm of heavy gear) and gives me the best of both worlds with both a fast prime and a VR zoom with decent reach. On the other hand I assume the 24-85 will be the worst of the zooms and it might be overkill for me with two wide angle lenses since I am not really that much of a wide angle guy but I do like primes.
The 24-70 seems like a good do it all option without the need to change lenses. The drawback is mainly the more limited zoom range and the added weight.
The 24-120 is the slowest option but with the ISO-performance of D600 I expect to be able to shoot even indoor concerts with this lens. The added focal length is of course a big bonus and 120 f4 will give a shallower depth of field for portraits than the other setups. Of course my other lenses are better for portraits but the best lens is usually the one you have on your camera at the right moment... Then again I would miss the ability to play with a short depth of field in the wide angle. For example focusing on the front row dancers while throwing the back row out of focus.
