Is it appropriate to buy a SLR or a micro-order for d5 and z62 wedding shooting?

If you don't want to change the lens, buy a SLR. If you change the micro-lens, you have to change it to a micro-lens accordingly. This is another sum of money. Although the micro-single can also switch the SLR lens, it is better not to switch the wedding shooting. Switching stability is almost meaningless. If something happens during the filming, it will be bad.
