The Sigma wins sharpness hands down. I like the liquid black of the Efke.

with taht Efke KB 25 means iso 25?
...I like first from Shangai and all from Efke.

edit: sorry for my ignorance...now it's clear to me about that efke film. Interesting stock indeed.

Yes, the KB 25 is a 25 iso film. I bought it to use my very fast lenses (like Vivitar 24/2, H40 85/1.5...) at their full aperture on my Pentax screwmount bodies (so with a max speed of 1/1000s) even in bright sun I have ordered one in 120 format for my 6x7, the same size of print compared to a 135 film would be an equivalent of iso 6 for the grain
That is not my less sensitive film, when I shoot with the Efke IR 820 (in infrared), I expose it around iso 1

[spleenone]

yes, there is utilization with those slow shutters (mean around 1/1000)
could be interesting try with 67 body... no grain at all! for price of shrapness apparently
and with IR film is it obviosity of very slow speeds. If I could shoot any film like that. Once I will and will be very happy =) ...mainly efke 820ir.

I do like the results from the Efke KB 25. Interesting...
