Originally posted by steephill A Nikkormat with a 135mm f1.4 lens? Surely some mistake? There is now a Mitakon 135mm f1.4 but I don't recall ever hearing of such a beast when Nikkormat was current.
It's reasonably safe to assume it's f1:4 (i.e. f/4).
To answer the OP, I do not, though I've had fun whenever I've cracked out a 135mm. There's a YouTuber/Instagrammer called 'IggyTheWiggy' (fun name) who typically uses a Sigma 135mm f/1.8 Art, but that's the closest I've heard of. FWIW, I don't much enjoy his YouTube videos but his Instagram can be quite useful for Lightroom presets, if that's anyone's "thing".
