Re: what I have. Old Nikon D70. 9.5yrs old. I still use it b/c I shoot off a tripod more than enough for my camera club submission for competitions against other clubs in the country and exhibitions. If I don't get shortlisted it's me not the equip. For low light you may want a newer camera not necessarily full frame.
I also have a D600 but honestly it is now in the box. I regret that, if I sold now I make even larger lost, there have been guys here buying a local $3,000NZ D600 and selling it for under $2,000NZ 2 months out. If I did more low light walkabout I may use it more but for tripod work sunset and sunrise I don't see that much a diff. The D600 does give a more ready image out of camera but you can always spruce it up in post editing. In hindsight maybe I could have gotten a cheaper D7000 for me b/c I have some older leness ie 9 or 8yrs old that a D5000 or D3000 doesn't autofocus with. For better skintones if I did much of that the newer ones would be better but I seldom do it.
I am using film for my own ways but that's not related. I just enjoy shooting slides slowly like 3 rolls per week on holiday and get it right in camera, like the process and challenge of film. And film has a bit of texture difference.
I don't doubt all the nice stuff out there. For me I don't see the expensive stuff really worth it. And it is just a hobby for mine. So what I do is get older lenses that is cheaper so I can get the 1.8 aperture or I recently got a much older 2.8 mid zoom for kids and family and friends while they are in the park and the garden or at the cafe etc. I think that if you are shooting into the sun or looking at the fastest AF for sports etc .. with the faster engine or the lens coating they may be useful to get the image. But they come at a price certainly.
With my club photography, I compare myself to this member at my club, she's about 70yrs old and she has won at least a competition with a camera magazine and she has been shortlisted with a city carnival we had and has sold at least two print at the club's exhibition. Received various other comments by photography judges who were invited to my seminar judging evenings. Recently she was interviewed on our monthly newsletter and she uses a Canon Rebel body, kit lens and she has at least a 28mm prime lens the cheap one. She also said that she prefers light equipment. Well ok she probably doesn't get up 5am for a sun shoot or shoot models or sport figures. But you know ... with the club it's general photography, the odd sunrise and other bits and pieces, I was with her when I was with a group where each month we were given a theme and we went out and photograph in our own time and came back to show others, from the 6 we chose they select 3 which would be used for the end of year club slideshow presentation to the rest of the club. Topics like "negative space", or "finality" or "golden mile" or "mystique". Edit - and she has never used a film SLR b/c she felt it was just too hard and now likes digital b/c she has the instant feedback.
But if you look up Mike Hollman locally here, who is a travelling pro, bit kind of an unorthodox, he has won some gold medal awards (those for working professionals) travelling to China and other places like that ie Yelllow Mountain and around where the Croutching Tiger was filmed. He does have some 2.8 lenses but at other times he has also used a Nikon D4 with a 28-300mm lens which technically is said to be inferior. As well as other 16-85 isn't that, a niceer lens but not the most expenisve. Check out his website or Facebook, he provides settings there ...
