Is the sigma fp l worth buying used?
Yes, I think the fp L is worth considering used. It's the 61-megapixel sibling of the fp, announced in 2021, and a used body is often most of the camera for a fraction of the price. That's the case I make in buying used.
Before you buy, budget for a new genuine battery, since old ones lose capacity. Also remember there's no built-in viewfinder and no stabilisation in the body, so pair it with stabilised lenses for slow shutter speeds. If you'd rather have the smaller, lower-resolution option, the Sigma fp is the one to compare.
