I had very many of the same thoughts- nearly a decade ago.
That was about 5 years before Canon saw fit to make their very first $30,000 Cine Servo Zoom for APSc sized sensors, let alone any of the lenses that came later.

You get to look back on a series of large sensor lenses made with servo zooms, but still lacking the range of ENG lenses made for (smaller) 3-chip sensor blocks. I was looking around when there was literally nothing unless you wanted to try and adapt film camera lens to a video camera. and at the time, the adapter market had not kicked in yet either.

You can read my early musings here:

You can see numerous videos about B4 lenses on M43, APSc, and BMD URSA on my YouTube channel:

You are also not alone. I have over 4,000 worldwide members in my B4 on M43 Facebook group. It has obviously extended beyond M43 cameras these days, but M43 still provides the easiest way to leverage these long lenses on a larger sensor camera.

So, welcome to the club. I appreciate that you covered well the tradeoffs of these long zoom lenses, and if people ar going to add an adapter, go to the end of the zoom range and pixel peep compared to a $2,000 prime lens, then they need to not be doing this at all. 🙂 It’s a tradeoff between hypersharp primes, and having a 17x (or longer) parfocal, constant aperture, smooth powered servo zoom lens that can get all the shots.


Super 35/Full Frame video and still cameras are a way for manufacturers to sell super expensive lenses to their customers. 3 Chip cameras have it way over single sensor cameras in sensitivity. An f1.9 lens on a 1/2″ sensor will give you roughly the same depth of field as an f4 lens on a Super 35. An APS-C lens weighs 1/2 of their full frame equivalent.
