    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:

    Their "counterparts", are regular still photography lenses,
    like this one:

    or this one:

    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,

    igmolinav : ) !!!

    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.

    Hi Archie,

    Thank you for your message : ) !!!

    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,

    igmolinav : ) !!!

    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.
