Close-focus on J8 & J9 wide open

[Peter_Jones]

I think the close focus on my J8 and new (to me) J9 seem OK

J8

J9

Both taken at f/2 focussing as close as the lens/rf allowed, on expired Fuji Sensia100 (handheld so not a scientific test, but lets me know I'm in the ballpark)

What was the focus point, Peter ?

 

[Peter_Jones]

The left-hand outer edge of the largest central ring (if that makes sense)

(actual POF depends on whether I was swaying in the cold wind or not at the time )

Spot on. You are lucky These are great lenses when they work as father Zeiss intended

May I ask what serial# your J9 has ?

(And thanks for the nice bokeh shot in the other thread).

Certainly, N7402xxx Black LTM. I got it from the Real Camera Shop in Manchester, UK last month with my Bessa R2. The focussing's a bit stiff, but not stiff enough to unscrew the lens unless the temp is below freezing. I've re-greased J8s and I61s before but J9s look a tad more complex with their double-helix - I'd need the house to myself for a while and a good night's sleep before tackling that
I'm relieved that it focuses well close-up, there's many a tale of bodged FSU repairs on the web

Cheers, Roland

closest focus + widest aperture = the hardest and true test for any lens.

For clinching evidence, you could do shots from a tripod or on a table top. A lucky man if you got a good J-9. They are reputed to be very difficult to reassemble correctly.

Looks great. I did a small "test" like that myself last year when I first got my Jupiter-9.

Scanned from the print. The distance was about 1m I think, maybe a bit more, at f2.
