Isn't the Helios-44 an M39 Zenit mount? If so, it won't focus correctly on an LTM body.
The Jupiter-8 is a fine lens, but very different from the choices the OP mentioned initially. All three of the lenses mentioned in the first post are double Gauss designs, whereas the Jupiter is a Sonnar type. I like mine, but the ergonomics are not ideal, particularly the fact that the aperture rotates in the opposite direction to Leica and Canon LTM lenses.
I'm not sure what the major difference is between the gauss/planar/etc design and sonnar style of element arrangement. (Edit: My brief looking around seems to suggest the Gauss design gave better performance at closer focusing distances than the sonnar types).
It seemed like there was a couple Helios-44 out there made for an LTM mount but they seem to be more expensive than the M42 version.
Seems I can get a Jupiter-8 that's been CLA'd domestically, but only if I want to get it along with a Canon P for 200 total ... which might not be a bad idea ... I'm assuming if it's been CLA'd then it's been adjusted/aligned in spec with LTM/L39 if it's going to be on a Canon P.
Seems the seller cannot assure that the Jupiter-8 correctly focuses with the Canon P (or any non-FSU body that is) because the lens was CLA'd before the seller acquired it and they just paired it with the P to sell it.
