A question about breathing - Documentary filming with dSLR

Hi,

I am relatively new to doing video : ) !!!
I have read that many people talk about cine or video primes.
They may look like this one:

or like this one:
http://www.bhphotovideo.com/c/produc...25mm_T2_9.html


Their "counterparts", are regular still photography lenses,
like this one:
http://www.bhphotovideo.com/c/produc...f_1_4L_II.html

or this one:
http://www.bhphotovideo.com/c/produc...5mm_f_2_0.html

I would like to do some very short documentaries with a dSLR and with
two or three still photography lenses. In the documentaries I plan
to do, for the most part, I'll interview people. So, the focus does not
really move. I may include buildings and/or landscape, but the focus is
pretty much fixed. (A friend of mine wants to film a dialogue from a script
he wrote. The people in the dialogue stay mostly in the same boring plane
as well ; ) !!!). So, there will always be very little movement back and forth
of the "focus plane"! So, assuming that there is more or less the same
video quality in the video/cine lenses as in the still photography
lenses, there is no need to be interested in those video/cine lenses.
That assumed, since there is very little movement of the subjects, and
therefore no breathing! Would this be correct?

I found this video on the internet, and I couldn't see much of a
difference between using video/cine lenses, and using still photo-
graphy lenses:

Thank you in advance, kind regards,

If your budget allows then go for the Cine primes.

If it's tight then still to L series lenses.

There are other things make cine lenses better than photography lenses apart from the breathing.

I would know more about those characteristics that make cine lenses better.
If you have a link or would like to comment a bit, I would appreciate it.

Kind regards,

I wrote a post on reddit which summarised most of the differences but I can seem to find it now.

I did find this link though which gives some good pointers as to the main differences.

I would seriously recommend going for L series lenses and spending the extra money on other aspects to make your film better as I doubt you would see little difference in the lenses as well as have a complicated time getting PL mount to EF mount adapters.
