Francois DionThere never was a 1.4x teleconverter for M42. Plenty of 2x, but they were not the best quality. I do use a lot of M42 lenses with my Fuji X series mirrorless camera. One way to use M42 lens and have a 1.4x teleconverter is to use the Fujifilm XF 1.4x TC WR. Mount it on camera, then use a M42 to Fuji X adapter, then mount the lens on the adapter. It is designed for a handful of Fuji XF zooms. It'll all be manual focus, of course, but it works.
You'd think that adding an adapter and a teleconverter to a vintage M42 ("universal thread mount", as found on #Pentax, #Yashica, #Fujica etc) would make for a combo that is too heavy and too long for normal use. It really depends on the lens you combine it with.
Here it is combined with a #Spiratone #reflex #Mirror #Lens, 300mm f5.6. The whole thing is smaller than my #Fujifilm 50-230, and about the same weight but almost twice the reach.
Randy Au 🙃@f_dion whoa! A retroflex mirror design! I've only seen a handful of these online and I think the last review I saw years ago said the high focal length plus relative lack of weight made it even harder to hand hold. How's yours been?
@Randy_Au if I shoot outdoors in well lit conditions, I can get away with 1/500th to 1/1000th (I'm not afraid of 3200+ ISO). There is no optical image stabilizer. The goal here is more for that artsy color vintage look at long distances. For ex, tree bark here at 40ft, Spiratone 300mm + 1.4 fujifilm TC.

@Randy_Au if I want extra crisp at 300mm + 1.4 Tc, I will use fujifilm's 70-300mm lens which has 5.5 EV optical stabilisation and autofocus and ridiculous optical resolution.
Still a manageable lens, especially compared to the 100-400 (but heavier than both lens previously mentioned)
@f_dion cool! Surprising amount of detail given the focal length.
It's great that modern sensors can push to 3200+ with relatively manageable noise and lets us do fun things w/ such twitchy lenses
@Randy_Au yes, and to think we had to make do with iso 1000 film… i think 6400 is right at the edge for apsc for daytime photo.
oku_yama_old↘︎ne-de@f_dion Most of 50mm and some of 135mm lenses for m42 are relatively compact. Comparing to Fujinon 56mm or 90mm they will be smaller.
@oku_yama_old i have this compact lovely Enna Werk, 35mm m42, made in Munich in the 1950s. The second retrofocus lens ever made after the famous Angenieux. Combined with an M42 speed booster, it is a very useful lens on apsc cameras.
kernpanik 🐾 🕊️ ☮ 🖖@f_dion I used a vintage Canon Reflex Lens 500mm S.S.C. (~1980) for a while, which is said to be one of the finest mirror lenses ever made. I got some fairly good results with it, however its optical qualities don't come close to modern tele zooms.

@kernpanik lovely! I’ve never tried the Canon mirror lens. I saw that Tokina reintroduced some last year with 6 different camera mounts. I wonder if it would be possible to make an optical image stabilization with a catadioptric design.
@f_dion I tagged some of the photos I made with that lens. If you're interested:

@kernpanik looks like it is working well for you for birding!
