I have a sony dslr camera thats about 10 years old, it doesn't take as good quality photos as newer cameras. I want to know if i should buy a lens or a new camera. What affects the quality more?
2As it is, this question can only produce opinions, no fact-based answers. We would at least need some information about budget, your current gear, what you are doing with it, and what lens you want to buy.– floliloApr 8, 2018 at 2:40
1The 10 year old models are different, but the question is essentially the same. Upgrading EOS 350D or changing to full frame for low-light improvement?– Michael CApr 8, 2018 at 5:07
1Related:This one is equally applicable to cameras or lenses. When should I upgrade my camera body?. Also: Should I upgrade my Canon body or lens for upcoming travel? and Will I see enough improvement moving from EF-S to “L” lenses to warrant the cost?– Michael CApr 8, 2018 at 16:01
Without knowing which camera you've been using for 10 years, nor which lenses you already have, it would be very hard to give you useful advise about what to purchase, but I can tell you that I'm currently using some lenses I thought I might never use again (Zeiss lenses for CONTAX 35mm cameras—lenses 30+ years old, in most cases). I bought a Sony A7R after the A7Rii was already out and was able to use my old lenses again. I actually did buy a couple modern Sony/Zeiss lenses and was not satisfied with the price/quality ratio (build quality seemed poor compared to what I was used to). At the time I bought that, I had a Canon 650D and the upgrade to "full-frame" felt like a good move; better than buying a new lens. But it depends on your goals, budget, and (of course) on what you already have.
