I currently own a Nikon D7100 and two lenses: a Sigma 10-20mm and a Nikon 18-200mm VR. I mainly use these for travel photography and more and more I'm getting into landscape photography for which the Sigma has been great.
I'm aware that the convenience of the 18-200mm does come with some compromise in terms of IQ although its by no means bad.
My question is, if I want to improve IQ what would be the best upgrade path for me in terms of lenses? There seem to be almost endless choices of lenses in the Nikon range let alone considering other brands. Its not clear to me whether I should just be looking at DX lenses or whether full frame lenses would work (I've seen this suggested elsewhere and am a bit puzzled).
Lastly, I'm not looking to do this in one go so a plan or an upgrade over a period of time is fine (don't think I could afford to anyway!).
Advice very welcome.
