Depends on what you want to film to be honest... it is SUPER wide.
Part of which means that you have to get reaaaallllyyyy close in order to get someone/something in the picture.
I made this with a 600D / Samyang 8mm / 55-250 kit lense...
Most of the shots with the 8mm, they had to skate so close that they almost hit me half of the time, and still looked miles away in the footage.
It's great though that it has MASSIVE depth of field, I normally just set it to F8, infinity focus and the depth of field is like 10cm to infinity.
I kinda chuckled that there's a cine version though.
The focus ring is pretty much useless with so much depth of field, unless you're at F3.5 in which case it's a bit soft for my liking anyway, a focus puller would have an impossible task to focus a lense that has so much in focus, and what's out of focus is *only just*.
I guess adjusting brightness with Iris pulls would be the main drawcard vs the normal version.
It's a bit niche though, there arent too many situations where I could think it's really useful for filming apart from sports etc I guess.
If I had my time again I'd probably buy the Sigma 10-22 instead, a little more expensive but useful in a LOT more situations.
