do you have a preference for mirrorless or DSLR
I recently bought sony 6400 + 30 mm F1.4 on
@Nomad suggestion...I am really liking it
Isn't α6400 an APS-C camera?
@Thread
One thing to also consider is the lens compatibility and how many lenses do you currently have for your D5500. Secondly since D5500 is an APS-C, if you would be buying a full frame camera, you may need to get a full frame lens as well otherwise you won't be taking advantage of it completely.
Second thing is if you still want to go with a DSLR or get Mirrorless. What would be your primary usage of the camera? Photography only, videography only, or both. You need to check your area of interest and which aligns with which.
I bought an α7iii last month but that goes way over the budget of 2lacs.
