I just did some tests and apparently the results are correct. The manual focus is not annoying given the large angle. only downside filters. Indeed, with the wide angle (convex lenses) and Samyang system, sun visor fixed, the filters are special, that door samyang filter (kokin). At the time today out of stock on other sites !!! CAR NOT THIS ITEM IN AMAZON !! damage Otherwise delivery and packaging say anything !!
