I have a D60 that has worked well in outdoor lighting, but leaves me irritated in low light settings. I've seen a few higher ISO cameras (7200 & 7500) and have also researched Nikon 750 & 610. While the ISO ranges on the DX models is higher, would the FX models be more responsive in lower light? I'm not sure if their is a little give and take between tha higher ISO capabilities and the larger sensor size
I'd say I'm more enthusiast than beginner and enjoy landscape photography as my primary passion. Fond of sunrises and sunsets and similar low light situations.
Cameras passed a major performance "knee" just after the D60 generation - marked by the D90 and D5100, both CMOS based (the D60 was CCD). Nikon DX cameras from of the current generation and the last one or two perform significantly better than your D60. This is across the board, but can be seen easily in landscapes and base-ISO applications - dynamic range has increased by at least 2 stops over the CCD generation cameras like yours, and the quality of the noise has improved - no more technicolor confetti and very clean files. There has been a slight change in the color discrimination of the newer cameras - even though the color depth has increased, some CCD users complain that the colors aren't the same owing to changes in the Bayer filter characteristics. This may not be visible to you, and shouldn't be a roadblock to upgrading.
My advice would be to acquire a D5500 or D5600 body, particularly if you're wanting to keep things small and light. The improvement will please you. The flippy LCD will make taking landscapes on tripods easier.
All true...but what does still please me a lot, the true-to-life CCD colors, this is where the D80/D60/D200 and also D40(x) still excel, even into 2018!
I do have more fun making going outside for a walk, not always intending to take pictures, and to have a camera by my hands, i still like to shoot my D60, D80 DSLRs...even my D40, much.
Remember: it's about the photograph, not pixelpeeping, not the latest gear & tech...or what would one say, about my decades old film SLRs? i still love them - and use them.
May i remind you, about what Ansel Adams said, a long time ago....
"A photograph is usually looked at, seldom looked into." ~ Ansel Adams
And i don't need to remind you guys, about that a D40x (10 MP, DX) can look like a D800 (36 MP, FX) at normal viewing sizes, don't you think?
For the non-believers....watch this:
So much as for gear stuff.... go out, take more pictures, instead of discussing the whole thing. Yes, newer tech is better, but old(er) one is good enough.
Good Light !
