New Lens Jupiter 3 LTM

They are looking very good these examples. Good to know that in the cold the lens is working smooth. In time I have to drive to Kiev and Mykolaiv.

But I have a "stand heater" in my Mazda 2.

I did some quick backyard tests of the J3+, C-Sonnar, and my custom J-3- modified to the Leica focal length, KMZ 1950 with Zeiss SN on the rear fixture. Dragged my Tripod an M9 into the "slush" left from last week's blizzard.

The J3+ has the edge on my perfect-glass KMZ 1950. I made the mistake of having a Sky 1B filter on the C-Sonnar, but matching UV filters on the J3+ and J3. I'll redo the test, hopefully better weather. The results are surprisingly close, once I saw the 1B was on the C-Sonnar and the day was very overcast.

I spent a lot of time getting the vintage J3 working- and am proud of it, the glass had to be transplanted to a new barrel. I currently have 6 vintage J-3's in Leica mount, 4 KMZ's, a 1975 ZOMZ and 1984 Valdai- all perfect glass, product of cherry picking over 12 years. This 1950 KMZ J-3 is my best of them. Next Sunny day off, will try to do justice for comparing these lenses.

I took the Jupiter-3+, a 1956 KMZ Jupiter-3 "perfect glass", and my 1934 5cm F1.5 Sonnar converted to LTM to Gunston Hall yesterday.

The rendering of the new lens is so close to the 1934 original it's amazing.

And the 1956 KMZ Hupiter-3, all wide-open.



The Sonnar and KMZ: I custom shimmed for the Leica, the Jupiter-3+ PERFECT agreement. I did not touch it, was perfect out of the box.

I've submitted a write-up to Lomography. I like this lens, it's amazing to see it in production and such care given to the implementation. This lens is as well made as the Nikkor 5cm F1.4, but has much nicer Bokeh. I have used the Nikkor on my S-Mount cameras and have the LTM version. I prefer the F1.5 Nikkor.

I had a chance to Thank the Jupiter-3+ team.



I also took the Jupiter-3+, Nikkor 5cm F1.4, and Canon 50/1.5 to the Udvar Hazy Air and Space Museum- the improved coatings of the Jupiter-3+ make a difference with flare. Also- the only place I could think of with Flying Cars.

I finished comparing the J3Plus with several more Fast Sonnars, including the Contax mount Carl zeiss 50/1.5 on a new Amedeo adapter.
