fast tele's 90mm and shorter

[jett]

I'm looking for a fast, not-too-expensive, tele lens in M or LTM mount.

Focal length: 50mm - 90mm, preferably 75mm.
Budget: less than $1000, but preferably closer to $500.
Max Aperture: f1.4 - f1.8.

What are my options?

I plan on using this on a Sony A7 by the way. I prefer RF lenses simply because I have film M bodies, and no SLRs. If there are SLR lenses that I should look into, then I'll perhaps look into those.

Heliar Classic 75/1.8. If you are after a hell of a bokeh, you could also try C Sonnar 50/1.5 or Nokton 50/1.5 or Canon 50/1.2/ 1.4. But on a SonyA7 I would suggest something like Minolta 58/1.2 PG, 85/1.7 MC or Zeiss Planar 85/1.4.

The Canon LTM 1.8/85 is a good lens. It generally sells at around the $500 range.
