Just talked to Heliopan about the variable ND filters - good news.

i see most guys buying the 77mm version and not the 82mm. . . why? Assuming both cost the same, wouldnt it be a better idea to buy a 82 and use step down cuz most cine lenses are 82mm filterthread? Or did I misread something :/
or another question would be why most you guys prefer the 77mm to 82mm
would really apriciate this info :)
thx

I think 77mm is a pretty standard size for cine lenses actually. I know that when Duclos converts old sets of 35mm lenses to cine spec, he puts 77mm threads on for that very reason. Plus most of us have a largest lens diameter of 72mm which means that 77 is realistically the smallest size to avoid additional vignetting from the filter frame.
 
Okay guys im lost....


Tiffen, Genus Eclipse, Schneider True-Match Vari-ND or Heliopan... What's is the best option today?
To avoid badskin with polarization i plan to use the old rotating pola filter, will it be enought or should i go for a HoyaProND filter kit instead and forget variND?

Please help... thanks

Personally I couldn't care less about the front filtered version. Why would anyone want to stack more glass in front? It can only cut down and possibly distort the light that comes in. You only add glass in front of the lens if you absolutely need to - and a ND filter is one such situation... but to then voluntarily add more glass?? As to thumbprints - you always have the choice of being careful... but once you put glass in front, you no longer have a choice - you are taking the penalty of extra glass 100%... with thumbprints, at least you have a chance to avoid it. But to each his own, of course, different strokes for different folks, and I respect that.

Virtually all high end DPs use other filters as well. You're looking at the issue in a techie-only way, not an artistic one. Who says all images have to be sharp? Why?

Then again few higher end DPS use vari-NDs because of the myriad artifacts, and because its' two pieces of glass vs one for no benefit over a single ND filter except convenience and low cost.

Blast me all you like, but you are not someone I consider more knowledgeable than the likes of David Mullen (and neither am I for that mstter), so I'll take his position on these matters over yours.
