HVX and 35mm adapater questions

Is there any big difference when using a still 35mm lense vs a film (motion picture) 35 mm lense with the adapter and the hvx???

Also, would using a HD lense with the adapter make sense since more detail would be fed to the surface the image is focused on for the hvx to pick up?

I am lost when it comes to the adapter business and I am just tryin to get a better understanding.

Thanks!
 
well I hope 20 000$ lenses are better than 1500 2000 $ still camera lenses.

But still camera lenses are good. And you can buy them cheap on ebay.

Hd lenses havn't the same mount if I remember well. And I don't think they are better than cinema lenses...
 
Still camera lenses can produce a plenty sharp picture for an HVX that's being shot through diffused ground glass. However, there are several reasons why cine lenses are substantially preferable:

1) cine lenses don't typically "breathe" (change image size as you focus). Still camera lenses can breathe a lot, because it doesn't matter to them -- they were never designed to "pull focus during a shot" because they shoot stills. Cine lenses are designed to pull focus during shots.

2) Still lenses typically don't zoom at all, nor do they zoom well when they do zoom. Cine lenses are designed to zoom and focus and perform well during the shot doing both.

3) Still lenses usually have very short throws for the focus ring -- very tight from min to max, whereas cine lenses usually travel about 270 degrees from minimum to maximum, making pulling focus far more accurate, repeatable, and easier.

Now, with that said, a $70 used Nikon is likely going to deliver an image that's in the ballpark with a $20,000 Cooke, and certainly when used through a diffused ground glass.
 
Great info barry, is this covered in the book? we ordered sunday and are still waiting with anticipation of it
 
there are advantages for still lenses over cine - still lenses are designed to capture a larger frame size then the cine lenses - so the image you are focused on the ground glass is larger and therefore has more information in it. On the flip side - the glass might not be so good so any gains might be cancelled out with cheap glass

....this is not an attempt at disputing you Barry, I'd defer to your knowledge any day of the week....it's just an observation....I was watching Island in the Sun (1957) just yesterday and there was a scene where the focus pull was sooo drastic that the lens not only breathed....it GASPED!!!....as for the film.....kinda dated....but the locations were stunning....that's what kept me interested.
 
I also found on the M2 that the cinema lenses, namely the Zeiss superspeed primes, are set to accurately measure off of the glass, working with the witness marks on the lens. The Nikon mount is decidedly not, with about a 1.5x discrepancy.
