Salah, you remind me on myself a year ago. With the slight difference, that I never asked anywhere for help but simply went in the internet, googled for "video DLSR" and read and read and read. I opened one link, read it and got offered 5 more. And read them and so on. Half of my time I spent on amazon. Not to buy stuff, but to read what the people say about the product. That was so helpful. One thing I learned is, that if you want to make it in this industry, you really have to go for it and put all your effort in it. Part of that is not to ask "what should I buy" but to go on the internet and inform yourself as much and deep as possible and then make your own choices. Of course it's good to get help but if you are not able to get to know all the accesiour that is out there by your own, then I doubt you will make it anywhere.
Search on youtube for the channel "VnadV". "South - A Short Film" is what I did when I had no idea how a DSLR works. It's bad, I know. "East - A Short Film" is what I did a few months later when I had at least some knowledge and "Stutong Park" was a little project I did a few weeks ago in morning spontainiously with my girlfriend. I did a lot more projects for other people and organisations. So far I haven't earned a cent but it was worth the experience.
I'll tell you what I bought but like I said before: Go, and get as much knowledge as you can by yourself. Read about the different lenses. What they can, what problems they have and so on.
Canon Rebel T3i
Canon 50mm, f 1,8 II
Canon 18-135mm f3,5-5,6 IS STM
Tiffen variable ND-Filter 77mm (+Step up Rings)
Cheap but big (and not at all fluid) Tripod (will be replaced by a manfrotto soon)
I bought it in the order I wrote it down. I borrow tripods before I finally got my own. All together I spend around 1500 USD.
But some of the stuff I bought in Hong Kong, were it is much cheaper.
If you really can not effort all this, choose the kit lens instad of the 18-135. You anyway don't really need more then 55mm for filming, because it's a crop camera. If you still have to save more then wait with the microphone. You can use the build in. The video quality won't be as good but it won't hinder you from learning. Of course you also dont need to have Camerastrip and lens bags but it makes it much more convinient.
Sorry for grammar mistakes, I'm a German.
