All of these tools are what I have found to be the most useful over my 5-ish years selling on Poshmark. They aren't necessary but will help improve the look and performance of your account.
Camera:
I use a Canon DSLR (Rebel T3i) for my photos. The Canon Rebel series is great but if you have any DSLR from the past 5 years, it will be great. The cheapest Canon DSLR is currently the Rebel T7 which is about $400. I would not recommend buying a new DSLR just for Poshmark.
Tripod:
Any sturdy tripod will do so here's an Aluminum Tripod that I really like.
My DIY Backdrop:
I ended up building my own backdrop because it is a lot more sturdy and useful that what I found on the market. Here's a blog post about how I made it.
Lighting:
I use a floor lamp that is super bright and the color temp is adjustable so that my product photos are as accurate as possible.
DYMO LabelWriter 4XL Label Printer:
I bought this label printer just about two years ago when I started growing my Poshmark closet. It has been really handy and made my packing process faster and cleaner.
