Caterman Posted February 18, 2011 Share #1 Posted February 18, 2011 Advertisement (gone after registration) Trying to get my head around the ISO numbers that are between the 6, 12 25 etc. So far I've got 6 8 10 12 16 20 25 32 40 50 64 80 100 125 160 200 250 320 400 500 640 800 1000 1250 1600 ? ? 3200 4000 5000 6400 Between 1600 and 3200 I came up with 2000 2500 & 3000 but there are only 2 dots Not that I am going above 1600 with anything but you know what it's like.

Caterman Posted February 18, 2011 Author Share #4 Posted February 18, 2011 Sorry should have given a bit more info This is my first Leica and I've only put 10 rolls through Wikipedia was my source of what I've come up with so far I'm using Diafine and loving the results but that means pushing all the speeds a stop or two Anyway the reason I started looking at what the dots relate to is I'm trying Acros 100 in Lc29 which gives a speed of 80 which I figure is one dot less than 100 I just couldn't find anything on the Internet that showed the iso dial with all the speeds indicated Dave Link to post Share on other sites More sharing options...

Caterman Posted February 18, 2011 Author Share #6 Posted February 18, 2011 Thanks for that Noel I'm really enjoying the M7 it's an absolute revelation. My only regret was not going for it earlier but I'm determined to make up for lost time. Nothings going to dampen my enthusiasm Dave Link to post Share on other sites More sharing options...
01af Posted February 18, 2011 Share #7 Posted February 18, 2011 Advertisement (gone after registration) Wikipedia was my source of what I've come up with so far. Oh. Wikipedia. So that explains it. ASA 3,000 is a non-standard intermediate step that got mentioned in that infamous Wikipedia table of film speeds only because once there was one single type of film using it. For practical purposes, it's the same as ASA 3,200; the difference is less than one tenth of an f-stop. Link to post Share on other sites More sharing options...
