Another split focusing screen Question

Im sure someone can answer this for me.I want to buy a katzeye split focusing screen for my K10D. I do a lot of early morning long exposure shots as well as a lot of ND filter work using a ND 400. Hour would the split focus screen go under these conditions.Especially as the ND filters are pretty dark to start with.

Let's see. It is 7:30am, raining and hazy.
The split screen, ( ME SUPER ), in my DS is not blacked out at 5.6. I just put the ND4 on it, darkest I have,and it still was not blacking out at 5.6.

A 10 stop ND is bound to black out the prism. Unless it is pointed at or close to the sun.

in the case here I doubt af would work either as it is almost pitch black.

you might be better off with the stock screen in this case because at least you can (maybe) see something to focus manually with

Why not focus first, and then put the ND filter on? The Katz-Eye will make your manual focusing life easier, but it won't work miracles if you cut down the light hitting it so much that you can't see it.

Just did a little calculating. It's 5 stops from f8 to f256. There is no way you will focus looking through the filter. The exposure times will be huge.

Thanks for that. I should have realises that as I normally cant see through the ND 400 anyway. Putting the filter on after focusing would be the way to go.

I have a 9 stop Hoya filter which I use from time to time, mostly pairing with my DA14. AF while not fast, is still possible with the filter.
