Ditto, we do not know what the OP’s idea of reasonable is. I was replying to the previous thread about lens price ranges. I have some vintage Nikon mount lenses, had a nice set of Zeiss ZF lenses, that were Cine moded by Duclos. But, I have found that if you are using a MFT camera like the Pocket 4K, to take advantage of all it features, MFT lenses offer a good choice in the $500-1200 range. Adapted lenses have their own set of issues, and is a route I would not recommend to a new user.
After having used adapted lenses in the original Pocket and Micro Cinema camera, MFT lenses were much quicker to use, smaller and lighter, and fit the small character of the camera better. I also had a full set of Veydra Mini Primes, MFT Mount, and before the new Pocket was announced, sold them because I thought MFT for cine and Video was coming to the end, which no new cameras released in more than a year.
If you want future proof lenses, than larger vintage lenses that can be adapted and PL mount glass is the way to go. That said, the OP wanted a nice filmic looking lens for head and shoulder interviews. So for that application, in a simple to setup and use, no adapters or worn vintage lens issues, the PL 42.5 or Oly 45mm lenses would be my first choice, and recommendation. For a full manual lens, the Veydra 50mm Mini prime is excellent, but very hard to come by now. SLR Magic is releasing a new MicroPrime cine lens, in $500-600 price range, slightly larger than the Verydra, but of a similar design.
We all have our preferences, and this is just my opinion, based on my experience.
