@Levas : I also have a 70-200 2.8 lens, which has a 70mm diameter too.
I don't know exactly what weather conditions I'll have. This is my itinerary, I don't know if this'll help you :
I'm travelling in August from Saint Petersburg in Russia (visiting at least 3 big cities or places, other time in the train) to Mongolia (biggest city+hike in steppes) then a little bit of China (Beijing->Shanghai), where I'll stay for one year.
The Sigma are sharp enough and don't vignette around 2.0 or 2.8/4.0 so I guess I'll use them at this aperture when I can and if I don't need a wider depth of field (for instance I guess I'll need wider apertures for landscapes shots with the 24mm)
@DFM : Oh I didn't know VNDs were polarizers.
The Tiffen ND circular kits with 3 filters I found only block 2,3 and 4 stops. Do you think it's multipurpose or I need for example ND8+ND32+ND100 ? (+ the polarizing)
