summicron rigig 50mm 1960 vs Jupiter-8

[zabo69]

hi,
i have a Jupiter-8 in my M6 and i have the opportunity to buy a summicron rigid 50mm f2 for 300€, from a friend in another city, in real world situations ( not pixel counting) what big differences will i notice in b&w and colour film? the diference from the two lens is worth the money?

Shoul i notice big differences? in what situations?

Regards,
Avelino

The Cron is definitely sharper wide open. The Cron also has noticable less contrast at f/2 and a bit less contrast over all.
300€ is great price (go for it you will not loose money on this deal!!!)
The J8 is a super lens but the mechanics suck and the rigid cron is about as good as it gets mechanically!

thanks!
in high contrast situations would i get more dynamic range images from the cron?

two years ago I compared all my leica lenses .. there is a DR cron (same optical formula as the rigid), a Canon 50/1.4 and a J8 among them:

theoretically .. yes, you should

at this size its hard to see a major difference between the 2 lens.

The Summicron is a vety high resolution lens with average contrast.

I'm using white J-8 from fifties. Mechanically solid lens.

But, if someone will offer me good Leica lens under good price, I'll buy it to compare.

The second Summicron version is a wonderful lens, especially for b&w. 300€ is a very good price for this lens .... I would buy it! But I already have one 🙂

True! It was also scanned with the ****ty flatbed so you can't see resolution differences.
But I'd say the f/5.6 shot shows some difference in contrast (All shots were on the same shutter speed and I scanned the whole strip at once and set white/black point for them absolutely equally)
