Fuji Superia 400 VS Superia X-TRA 400

[fredus]

Hi there,

 

What is the difference between these 2 films ? Which one is best ?

They're pretty cheap ...

 

Thanks !

They are probably the same thing, just different labeling or a misprint in the advertisement. Superia XTRA 400 replaced Superia 400 several years ago. Fuji no longer manufactures the non-XTRA version of Superia 400.

I'll muddy the already murky waters with this bit on Fuji ISO 400 edge codes. Fuji Superia Xtra 400 is CH-7; Fuji True Definition 400(a tweaked Superia?)is CH-11. I've yet to see the CH-11 variant around Toronto.

TrueDef 400 is a weird product. Fuji rates it at RMS 5 for grain -- same as Superia XTRA 800 -- and it has the same resolving power. I guess it might have a bit less contrast than the Superias, and maybe less saturation... but you'd get that, plus finer grain, with NPH/Pro 400H. I think I'd be inclined to shoot Superia XTRA 800, rated at 500 or 640, before I'd bother with TrueDef 400.

R.T, where did you find a datasheet for True Def 400 CH-11?

I finally finished up a 4-pack and probably could not tell

the difference betweeen CH-7 and CH-11 in a double-blind study.

Same salt-sprinkle grain in skin tones, as per attachment.<div></div>

Data sheet for CH-11:

Interesting. The datasheet shows that it should be noticeably sharper than xtra 400 (but trading off more grain.) Maybe I'll test a few rolls next time I'm at Walmart.

The grain doesn't look like RMS 5 to me, but who can trust datasheets?

Note how CH-11 is supposed to be lower contrast than NPH, but I don't

see it. Characteristic curves max out at RGB 1.9 2.4 2.7 for new NPH

but 1.9 2.2 2.4 for True Definition 400.

Datasheets and RMS and curves aside, the best thing to do would probably be to perform a good side-by-side comparison of True Def 400 vs. High Def 400 and/or 400UC. Maybe toss in Pro 400H for good measure. Anybody up for it?
