I'm thinking of starting a small business by getting a high quality lens or set of lenses for 10-25K, I
am guessing PL mount or changeable. I can use it, rent bodies when I'm shooting, or rent lens out.
I will start with just this one product and compete by underpricing established houses.
For my personal use a short zoom would be most practical.
Angeniuex Optimo DP 16-42 might be in my price range,
ARRI / Fujinon Alura 15.5-45mm T2.8 Zoom also
but I don't know what midrange shoots are using as I'm a little fish.
I figure it's likely to last a lot longer than a camera if taken care of.
Maybe there's a prime set that would be more marketable.
