there is nothing to improve in it, it is perfect, want to delete each frame from it, the picture, like everyone elseโs L-k, is super. Got pros: some solid pluses, especially focus speed and sharpness, no one from L-k has such sharpness in the open, kenon can easily make a 1.4 hole out of it with such sharpness. With its cons: there is no dust and moisture protection of the latest generation, but it does not dust anyway
