Any luck Using ND Filters on Sony A6000/A7x - got samples ?

[omerb]

I got a B+W 10 stop ND Filter and took it for a spin on my A6000 w/sel1670z. Under cloudy conditions (less light) I could manage ISO 100 F11 ~30 Seconds but under brighter conditions even at F18 and <20 seconds was really overexposed.

Do I need an even stronger ND Filter ?

Are there any experienced folks out there who have used ND filters successfully for daytime long exposures on these Sony cameras and is it better/worse than on a DinoSLR ?

not sure what the difference would be on a sony mirrorless vs a DSLR because it all about the light. there's just too much light when in bright day conditions.

for example in bright condidtions outside where you might top out at 1/4000 shutter, a 10 stop only brings it down to 1/4s. 1/1000 only goes down to 1s.

its all about the light.

if you are trying to get a 20s exposure with 10 stop ND on ISO 100 then the original exposure would have to be at f22 and 1/50s based on my exposure calculater.

Not sure what the point of using a 10 stop ND filter for a desert landscape is.....

If blurred/streaked sky is your aim as Dquangt suggested, then maybe you could take two shots at different apertures, one for the sky as F22 as if it was blurred I guess any diffraction at that aperture wouldn't matter as much, then use the F22 longer exposure sky with the F11 desert?

Or stack ND filters? (And/or CPL)

Stack or mix in a split nd but with these long shutter speeds you'll need a filter holder, won't be able to hand hold. I would avoid using a screw on split, to hard to get the split where you want it with screw on's.

There is a technique and I can't remeber the photographer who specialize in what you want to do. They take multiple shots then stack them and you'll get a cool smearing of the clouds. Perhaps some could help out here...

Don't know if this helps but I did some search of reviews of ND filters and decided on this a Tiffen Variable ND filter. Works for me but I am no expert in this field. An example of Tel Aviv using it.
