Leica Jupiter-3+, Lomography

This is the only Seven element in Three group 1-3-3 Sonnar made in the 21st century. Leica thread mount with a cut in the threads to allow for close-focus. Leica M-Mount included. These are on the M9, quick tests shots. More will be coming.

Wide-open on the M9.

We were stuck inside, lens arrived just after the Blizzard of 2016.

The focus is accurate across range on my M9. Full-resolution images uploaded.

Wide-open at F1.5

Infamous Fencepost, used to test hundreds of lenses.

I've rebuilt over 200 Jupiter-3's, converted about 50 Sonnars to Leica mount, and rebuilt 10 or so wartime Sonnars for people.

Some green- most everything is covered with snow.

I'm using a 1.25x magnifier on the M9,

This lens is built to the Leica Spec, focus is smooth across range, no play in the focus action, modern coatings to control flare, and optical corrections are done with attention to out-of-focus areas. The Jupiter-3 uses two guide screws in in rails to hold the helical together. As you focus, these guides ride in the rails: if the heads of the screws are too small you get play in the focus as they shift in the rail; if they are too big they hang-up on the sides of the rail. The focus on this lens is smooth, and does not bind as many vintage J-3's will do. I've spent many hours polishing down metal on vintage Jupiter-3s. The Lomography Jupiter-3+ got this mechanism just right. This lens compares with the vintage Nikkor lenses for build quality.

Now I just need some better weather! Will be taking this out with the C-Sonnar, Vintage J-3's, and vintage Sonnars. Until then- lots of inside time.

Mine is in transit, should arrive February 4.

I am going to Korea for three weeks in March and will likely take just one camera and one lens. Most likely a Sonnar on the M-E, but I may just sneak the M Monochrom instead.
 
For any important trip like this: always take Two cameras and Two lenses! Five is Two, Two is One, and One is None.

And- you have to see how it compares with the 5cm f1.5 Sonnar!

Its not an important trip photographically. Its my annual training in the army reserve. I will get a few days to wander around, but I'm in Seoul twice per year, every year.

I also get very minimal secure storage space, so I prefer not to bring a lot of expensive gear. My backup is my Canon 6D and 25mm f/2 Zeiss Distagon in case I want to go shoot some architecture.
 
Some fine points to add: the J-3+ uses the same aperture mechanism as the original design, no click stops and geometric progression between stops- small stops are closer together. The aperture mechanism itself is well damped, and like the original- probably uses a dab of grease under the ring. I like to use vacuum pump grease when I rebuild a lens.

An original, 80-year old Sonnar looks like this... after 80 years, they used too much grease and it flowed onto the blades.

My solution, clean out the old-

In with a little dab of thick grease. Smooth as Butter, does not flow, stays put where you set it.

I suspect the new J-3+ should be good long after I am gone.

My Jupiter 3+ arrived yesterday. Here are the first test shots. The Monochrom shots are without a filter as my 40.5 to 46mm step-up ring hasn't arrived yet.
