To be honest, most of the times I do well without AF, but there are certain moments wich i really miss it (instant shots, holidays etc) and for these cases i might be ok with only one lens for low light and subject isolation. Already owning the kit zoom (only used once) , I'm between the 55 and 85mm, but finally i would go with the 85, because I don't have any lens in that FL. I might end up disappointed with Sony for it's plastics ,who knows. This russian is indeed a very good performer, sharp and nice bokeh, the third picture I like the most. |
That's understandable. I've only bought the cheap 50/1.8 lens to test the functionality of a native E-mount AF lens. As I own already many legacy lenses and Minolta AF ones as well I've rather invested in both the Techart and the Sony LA-EA4 adapters instead as these new Sony E-mount high-tech lenses are far too expensive for my taste. Furthermore they all become useless if I decide for any reason to change my camera to another system in the future again. _________________ Thomas Bernardy

I took out the 0.28mm shim and set the aperture ring back to original position. The problem- with the increased shim, the lens could not be focused to infinity. A J-9 on a Leica, without any adjustments: Infinity is in focus, close-up will back-focus.
New solution: one layer of copper tape (~0.08mm) on the RF Cam. This leaves the optics in the original position, meaning infinity can still be reached. The RF cam pushes back more, bringing the RF and actual focus into agreement for close shots. Focus via RF is good from 1.5m to about 8m, after that- focus slightly past what the RF indicates.

I agree. This is the 1967 J-9, export version. Not quite as good as the KMZ J-9 that was adjusted and traded for it.
Bokeh is not as smooth as the original 8.5cm F2 Sonnar.
Most Sonnar formula lenses have a high degree of field curvature. It's like a Sine-Wave for the are of best focus, not a plane. Used properly with a 3-D subject, can be effective.
I just finished a test with a Canon 100/3.5 in LTM. Most of this type of lens has damage to the element behind the aperture, bad reaction of the type of glass used and lubricants. I bought an FL version of the lens, the glass is fully interchangeable. It's sharp. |

If you are looking for excellent edge to edge sharpness a Sonnar maybe not the right lens for you, irrespective of production time. Even the new Zeiss ZM Sonnar is only mediocre in that respect. _________________ Thomas Bernardy

Hi,
the version of the Jupiter-9 85mm f2 with multi-coating MC is also the sharpest in your opinion?
Thanks. |
No, but has its moments. Haven't seen many example images over the years that impress me much. YMMV but mine had sickly yellow cast to it. You can all chime in on why, but I got rid of it and not looking back. _________________ "Lenses are to be looked through, not looked at."

Wide-Open, 1.3m on the Leica M9.
J-9 Test, 0.82mm Adapter. M9 by fiftyonepointsix, on Flickr
Combination of polishing down the LTM to M-Mount adapter to 0.82mm, reducing the main shim for infinity focus. Focus with the RF is good from 1.3m to ~10m. After that, use the focus scale for distance- infinity marked is actual infinity.

Better than adjusting the main shim for close focus, which means focus will never reach infinity.
