Yes, no doubt the difference is visible now. Even if the Jup has two small handicaps: the diaph wide open at f2 rather than 2,5 and the focal: 85mm against 75mm.
But I am a bit surprised by the wide open photo with the Jup. It doesn't fit my experience with such a lens. What is the serial number of this Jup? On the other hand, my 1950 Jup 9 is in fact a real Sonnar...
Thanks for the comparison. Jacques. |

Fortunately you can see the difference now about a modern Leica lens and an old Zeiss design, pre-WW II.
1:1 J-9 on F/2,8 with the Leica will follow.

J-9 F=2,0 (wide open) in daylight with reflection screen via LTM-M adapter on M7.
Summarit F=2,5 (wide open) in daylight with reflection screen on M7.

Just one of the first photos in practice with the J-9:
Also on Retropan 320 Soft. With the Z-6 and universal VF you have to watch out for the parallax correction of this 85mm lens. The closest range is 1,15m while the Summarit focus is up from 0,9m.

The first is the F/2,0-85mm Jupiter, the second the Leica Summarit F/2,5-75mm.
You can read my mind .....
New setup:
With reflection screen and environmental light. I just found an adapter Leica LTM-M and used the new set up, linear in exposure from 1/1000s-1/2s with the M7 where the Schwarzschild effect of the Retropan 320 Soft film is starting.
The testfilm is already hanging to dry. 
What you can see of above test photos: The J-9 is a bit softer on wide aperture but pretty close to the 20x more expensive Leica lens.

Thanks, Robert.
Could you say which photos are made with which lens?
If I understand, you have used two couples, the M7+Summarit and the Zorki 6 + Jupiter for the comparison. Why not the M7 with a LTM/M ring for the Jup?
I would be very interested too by a daylight comparison, without flash, if it is possible.
Last: what are your conclusions?
Amitiés. Jacques. |
