It really is, I could confidently keep this at 2.8 for these type of images [I would be stopping down a lot more for actual macro] and it's a comfort to not have to worry about distortion or any nasty CA - as it just doesn't exist - makes processing the images a cinch too. It's a little hefty though and can be tricky to master for close ups because of this, but I've had heavier macro lenses in the past like the Sigma 150mm OS when I shot FF - that one was over 1kg, the Laowa is a bit kinder on the wrists at 638g [though, closer to 800 for me with the metal adapter]
I'd love to try the native Fuji mount version, the Laowa 65mm - pretty much the same lens [also 2.8, also capable of up to 2:1 macro reproduction] in a lighter, tidier form and designed specifically for APSC. One advantage to the 100mm, besides it being a fair bit cheaper when I bought it, is you can get some really nice compression and blur out those backdrops easier than you would with the 65mm. But that 65mm version would be much easier to single hand hold if using off cam flash, also would fit into smaller bags a lot better and no need for an adapter. I could eventually sell this one on and get that 65mm, will see how I feel as I go along, enjoying it for the moment.
