For me the spark lens wasn't that hard to get the concept of. But it depend with lens you ended up uses. this lens was the hardest for me to get focus pictures of. I was having major difficultly with focusing. Also I feel like out of lens this one I had the lest difficultly with pictures. This was my day 3 so i was running out of ideas of places to take pictures of on campus. So i went to places that i tried with the other lens where the pictures were bad and reshooted with a different lens.
