Should I upgrade from the fujifilm x a3?
Whether you should upgrade depends on what's holding your photos back. The Fujifilm X-A3 has no stabilisation in the body, so if blur from shake is the problem, a stabilised lens will help without a new camera. From its lens list, I'd look at:
- Fujifilm XF 16-80mm f/4 R OIS WR for a wide-to-standard zoom that covers most everyday shooting.
- Fujifilm XF 50-140mm f/2.8 R LM OIS WR if you want a brighter telephoto option.
- Fujifilm XF 150-600mm f/5.6-8 R LM OIS WR if distant subjects are what you're missing.
If you do decide to move to a new body, buying used is a sensible way to get more camera for less money.
