Looking at how inset the rear element is, I suspect if you remove or modify the rear baffle the FE teleconverters will fit the 70-180.

Food for thought: if 180mm is just a small crop of 200mm, and 135mm is a small crop from 135, as is 100mm, why not just use a 24-70/2.8?

200mm is longer then 180mm. The DoF is less. If you see side by side pictures there is a noticeable difference between 200mm and 180mm. However, I think it probably is worth the weight and money savings.

Why stop at 200 mm? I tried a 70-220mm F3.5 briefly. Tamron has a recent 70-210 F4. Canon has a patent for an RF 70-240 F4. Sigam has a 120-300 F2.8 (which supposedly loses a ton of focal length at portrait distances.)

DoF is constant with the same framing and relative aperture. I am in favor of lenses with more depth-of-field, especially when combined with good transmission.

You're right, with modern high MP sensors even a prime becomes a 1.5x or 2x zoom
You can see the April Foolishness 2023 exhibition here Another great show of the talent we have on Dyxum

Did have that thought but I rather some else do it first

Yep we just need a really sharp 10mm prime and a 1terapixel sensor.

Of course not. I would love that Leica 90-280/2.8-4 in E-mount.

As long as it has an f/2.8 aperture so that I can use it in low light!
