No, the whole point of cling wrap is that it's thinner than any filter and helps with the weather sealing. Also, I used to gel my flash, but with the new colored cling wraps, I can get that effect across the whole picture, and that's a lot easier than just adjusting the hue in post.
Even more important, my US$13,000 600/4 II can't even take a front filter. How lame is that?!? Fortunately, cling wrap works just fine.
Thanks. Interesting. There seems to be a lot of difference between what happens in the US and what happens in the Far East, at least at pro journo level. I am in numerous press conferences every week, major sporting events frequently and have never seen anyone use cling film (or wrap as you call it). Mind you, I have never seen coloured cling film either. Live and learn.
And, why would you want a filter on your 600/4? The lens hood is big enough as it is.
Because I love cling wrap. I put it on my camera lenses, on my microscope objectives at work costing far more than the 600 II, on my sunglasses, on the windshield of my car and on the windows of my house. I just can't get enough of it. I'm thinking of wrapping my whole house in cling wrap, and then maybe my cat. Meow.
And because I'm honestly afraid that you still might not get it, the whole line of discussion around cling wrap, starting from where the sardine sandwiches didn't turn green, is satire
Yuk it up, these are the jokes.
