Most of us go through this search at one time or another. For me I like the new Delta 400 in emofin (2 bath). It gives me 640 - 800 speed with the tight grain of a 400 t-grain film.(posted 8244 days ago)
TMZ gives grain but when you start to shoot over 1250 or so then your choices narrow and you have to use TMZ and live with it...
