Отзыв о Adapter Ring M42 - Canon EOS Alloy от Hayden Lim (Hayden L ᠌

Tested on Canon 6D and 600D cameras. I put Helios and Tair lenses . In both cases, it came up like a native, but both here and there the digital markings of the lenses turned out to be on the side. You can use it, but the "Chinese" obviously did not think of this important nuance. Got pros: The adapter does its job perfectly. The thread is cut without distortion, so that the lenses are wound smoothly and without problems. Cons below: Incorrect final fixation of the lens (after screwing it point-blank, the scales for marking the depth of field and distances on the Helios 44-2 lens are obtained not from above, as expected, but from the side (photo). This is definitely ugly and most importantly inconvenient. By the way, it is not possible to remove the adapter directly from the lens it will work out, no need to panic and run to the workshop, install the entire structure back on the camera and remove the adapter only after unscrewing the manual lens (it's a little inconvenient, but it works).
