Good point Matt makes on having Fuji do the research. If I were Venus Optics, I would have gone a step further…and copy more. Maybe a 28 as well. When I tried the GF T/S lenses, I found the 30 and 110 to be well chosen focal lengths. Very useful. Except the 1/2x magnification at close focus, I need an extension tube to get closer to 1X. So the Laowa 100 being capable of 1X is an advantage for my use case.
Other than the lower shift compared to the GF, I think the Laowa at f/2.8 wide open is nice. Offers a bit more flexibility, though not really useful for macro or architectural work.
