Canon to Come Out with a Canon RF 14mm f/1.4L VCM?

[GMCPhotographics]

Conventionally:
<24mm = ultrawide
24-35mm = wide
36-69mm = normal
70-299mm = telephoto
≥300mm = supertelephoto

We can all make up our own definitions, of course.

‘Fast’ is more loosely defined, but generally faster than f/2.8 for primes and f/2.8 or faster for zooms (not counting supertelephoto lenses, where ‘fast’ is anything with a front element diameter ≥100 mm).

Telephoto is a type of lens that has curious definition. it's a lens that employs a telephoto group, which extends it's focal length beyond it's normal phyical length. This means a telephoto lens is one that employs this design and has a focal length longer than it's physical length. This is a bit of a bizarre definition, because it fails to mention the length of the lens including the distance to the film (or sensor) plane. So for example a EF 85mm f1.4 LIS is not considered a telephotos because the lens is longer than its focal length, where as the EF 85mm f1.2 L is physically short then it's focal length. However, put the EF 85mm f1.2 L on a EF to R mount adapter and neither are considered to be telephoto because the lens is now effectively longer to the mount. If we take a RF 24-70 f2.8 LIS, it's not considred a telephoto becuase it's focal lenth is less than it's physical length. But it is pushing into tele territory. I think even a RF 24-105 f4 LIS isn't considred a tele by this definition either. Some definitions add clarity to conversation, other just seem to add murky waters.
Yes, in general terms, anything between 70mm and 300mm is commonly termed as Telephoto.

I do question this patent for a RF 14mm F1.4 VCM, with a stated focal length of 14.4mm and the short image circle that clearly needs digital stretching....surely that going to be closer to a 15mm lens in real world use? At the tele end of the focal scale, a few mm in focal length doesn't mean much but at the wide end 1mm means quite a lot to the angle of view.

The 14-35L is even wider if corrected. If I export a picture from DxO to LR I can choose "largest rectangle" and get an image which is 8600px. The sensor of my R5m2 has only 8192px.

There is a difference between the terminology for lens design and the terminology for categorizing focal length. The latter is really about angle of view.

A 35mm lens on FF is a wide angle lens, but it’s a normal lens on APS-C, edging into the telephoto range on m4/3 and is an ultrawide lens on a larger (e.g., Phase One) medium format camera.
