I recently acquired a new-to-me Canon A-1 in near mint condition and am intrigued by the fact it's the only 35mm camera I have that goes up to ISO 12800. The only film I know of that goes that high is Ilford's 3200 with an additional 2-stop push to ISO 12500. I don't expect miracles at this ISO, but curious, anyone have any sample shots (only at ISO 12500) they'd care to share?
Or any other film suggestions for utilizing this ISO setting on my camera?
I've not shot at it personally but I have developed to that high, using the APUG user recommended method of chosing the developing time 1 stop above what you actually used when developing in microphen. I estimate (was using ilford sporti and holgas at the time, with handmeter that only goes up to 3200) that the IE was probably around 6400 which is why I chose 12500 for development. Was a wedding in a very extra dark church/monastery. But that was medium format... I think my husband was using the Nikon FG at 3200 and I pushed it 1-2stops for that. It is fairly pronounced grain in comparison to hp5 or delta 100 but it was useful in this case.
Kodak TMZ P3200. But the Ilford film is faster and gives better tonality. I've used both at up to 12,500 but normally shoot at 3200 nowadays in the interests of tonality.
I'll second the recommendation for extra development.
You can also try high ISO color film and develop it in traditional B&W developers to push to 12,500. I haven't done that since college back before photography was invented (GRIN), so I have no memory of what I used.
I think it was a 400 ISO transparency film developed in Acufine. But don't quote me on that.
