I agreed with what others say too... an external flash is almost a must for macro shooting. so be sure to take that into your budget too.
Jus my personal opinion, Tammy 90mm would be a reasonable/gd macro/ portrait lens if on a budget since it cost ard 500+ and if u get it in hk it's $400+.
I use my Tammy mainly for portraits( not reali into macro yet)
If u wanna try it out, I dun mind lending ya tgt wif nissin 622mk2 which I'm using ^^
To you, they may be just a pet but to them, u r their everything
