Needs a third party app, like the fimic pro, which is expensive app. Cannot use the anamorphic lens, using the built in camera app on iphone. While using the filmic pro app, the image gets stretched even without using the anamorphic lens, and actually there is no difference with ot without the anamorphic lens, except the blue lens flare, so in my opinion, try the filmic pro app first before you buy the anamorphic lens, Sandmarc should mention this clearly that you must buy filmic pro app
a great lens with a huge options to use! i really love it!
Only a 4 because the lens doesn't have a lock point and occasionally turns when using the Polarizing filter or my fingers just accidentally move it then everything is skewed of course. I shouldn't have to be looking out for that and EVERYTHING else too..... I put a piece of tape on it to keep it squared up horizontally with the iPhone lens. And - it is very hard to screw on to the case mount. I'm very dexterous but I feel sorry for someone who is not. It takes a while to get the hang of, definitely. Otherwise, it's a beautifully subtle lens.
Love shooting ultra wide with this and Filmic Pro! They are a great combo! It’s a bit challenging to mount the lens to the phone, though.
