I'm trying to figure out the best prime lens for video. Help is appreciated. Here is the story:

 

I bought my a6500 mainly for 4k video, not so much pictures. I've always been a medium zoom lens type of person and I have the 18 to 135 mm. But recently I've decided to do some green screen work for my YouTube. I started thinking maybe I should use a prime lens for this. I was looking between 35 mm and 50 mm and decided that a 35 mm would be the best option. A 50 mm would be the equivalent of 75 mm with the crop factor, and that is too much. But then I realized 35 mm is a 50 mm with the crop factor. So what lens would you guys recommend to achieve 35 mm? Also another thing I realized is when shooting in 30fps in 4k it crops it even more. So what would give me a 35 mm equivalent with the video crop?

 

Another reason I decided on the prime lens is because I originally wanted to get a 10 to 18 mm lens. But then seeing the price of that lens after just spending 1000+ on my a6500, I cant justify dropping another G. I noticed prime lenses are way cheaper. Worst case i can just continue using my 18-135 and save money by not getting any other lens. But I just figured maybe a prime lens would be better especially with the larger apertures they have. Thoughts?

Don't think of the crop factor if all you ever used is an APS-C camera: the fullframe equivalence has no significant meaning to you. My advise is to try your 18-135 a bit on various focal lengths (e.g. 23-ish, 35 and 50) and see how that works for your videos. Then buy a prime at whichever focal length you like best.

If you really want 35mm FF equivalent focal length, the Sony Zeiss 24mm f/1.8 is a real gem. Also costs close to €/$ 1k. On the other end of the price spectrum there's the cheap but decent Sigma 19mm f/2.8 DC DN.

After looking at the suggested lenses and reading reviews, I came to the conclusion the Sony 24mm 1.8 would be the best choice. However due to it being a 1k lens (and no oss?!) I will have to pass it up. My next option would have to be moving up to the Sony 35mm 1.8. After testing out focal length ranges with my 18-135 as suggested, 35 mm (52mm) would still work for me. Worst case i can always move the camera back a little bit if anything. I will have to take a trip to B&H to check the lens out in person before I buy it. After looking at reviews and watching videos, I'm pretty confident that will be the best lens for me. They say to always have a nifty fifty, and the 35 mm is just that. Thank you everyone for all the suggestions!!

 

P.s. if anyone is interested my YouTube is www.youtube.com/mustang2005 if you'd like to see the green screen work I'm trying to do. It's the videos titled "mustang2005's rants."

Since your a6500 has sensor-based image stabilization the lack of OSS in the lens is not really a miss. I do agree that the 24mm f/1.8 is expensive for what it is though. If the 35mm f/1.8 fits your desired focal length, also consider the Sigma 30mm f/1.4. About the same price, optically better than the Sony 35 but no OSS.

Ahh.... I will consider this too. it sounds like a good lens. Now to decide between the two. Definitely need to test both when I go to B&H!

So I went to B&H today to look at the lenses. I want to thank everyone for all the recommendations. I think I'm definitely going to go with the Sigma. I made a little review video of both sony and sigma lenses if you guys are interested. Again thank you everyone!

What you say in your review about the color tone difference is true: I recently got the Sigma 56mm f/1.4 to replace my Sony 50mm f/1.8. Color tone of the Sigma 56 and 30 should be comparable, as should the Sony 50 and 35. My Sigma 56 produces much warmer tones than the Sony. I use it mostly for portraiture so am quite satisfied with the rendering of the Sigma.
