Not a bad lens, pretty sharp and very compact for its size. However, it is too expensive for such a simple design with a single aspherical element. I would wait for a discount or use it. Hopefully someone like Sigma will release a first for this format and bring some real Fuji to it. Edit: February 2020 I told you it was overpriced! Now it's 50% off (HALF PRICE!) - and it should have been from the start. Fuji is clearly cheating early adopters. Beware. Honestly, I'm repelled by them as a company. Why invest when you can cut the cost of your equipment in half in just a few months. PS: The body of the GFX100 will no doubt be getting a discount soon too - expect at least a $2,000 discount and maybe a $3,000 discount. Wait.
