Do I need ND filter?

[tester]

I'm going to Thailand for three weeks and I'm wondering if I should buy ND filter for M9 with Biogon 35mm f2?
I love to use Biogon wide open and with ISO 160 it can be impossible...
If yes, please give me advice - ND4 or ND8?

Regards
T.

On a very bright, sunny day, I use a 2 stop ND filter on my 35/1.4 Nokton and 50/2 Planar with the ISO set to 160 which gives a shutter speed between 1/2000 and 1/4000 wide open. As my M8 goes to 1/8000, I don't use an ND filter.

I'd suggest that if you wish to guarantee the ability to shoot wide open, that the sunlight will be harsh and that stopping down to f2.8-4 would be unacceptable, to pick up a B&W 43mm 193 ND 0,9 - the 2 stop ND I use on both those lenses.

I would go with 3 stop to be safe.
To be able to shoot at f/2 on bright sunny condition, you will need to be at 1/8000, ISO100

I had a need for one recently and stumbled upon this: http://www.promaster.com/products.asp?product=9301

It is on the lower end price-wise but it is well made, optics look fine, and it simply works great.

Thanks for prompt reply...second question is what about UV filter when ND is on the lens?

I use a 0.9 (3 stop) or 0.6 (2 stop) ND filter on bright sunny days. Or maybe I should say, I use them when I remember to pack them. It's definitely nice with the M2 because it only has a max shutter speed of 1/1000 and I'm often shooting with ASA400 film. Not as much of an issue with bodies that go 1/2000+.

Filters normally stack. Have a look at your UV filter - it should have a thread on the front.

What would you need the UV filter for?😕 Take it off before you mount the ND one. Stacking filters can produce all kinds of nasties on your image.

Jaap - I have a few questions

Do you use filters much? I haven't used anything other than my UV / IR Blocking filters.

Is a Lee filter system ideal? Or too much blocking? It seems useful because using adapter rings for different lenses seems a more cost effective solution than buying the required filters for each lens.

In upgrading to the M9 - I was wondering how I might mitigate IR contamination on a Zeiss 25mm biogon if using IR filters cause cyan colour shift.
