Still 35mm verses Super 8 zoom ratios?

[gene_can_sing]

I have one LAST question about doing a Nikon zoom lense to Bealieu adoption.

Bjorn Anderson stated:

"If you fit a still camera lens on your Beaulieu via an adaptor, you will receive “very much telephoto. To compare you have to use a factor 6,3 to multiply. A 100mm Nikon 24x36 camera lens is like a 630mm Super 8 lens."

and Mattius (Forum member) stated: "the focal length remains the same and so does the zoom ratio, but the smaller the image the more tele you get so for the same angle of view."

So does that mean that an adapted 100mm Nikon lense which then becomes a 630mm Super 8 Lense can zoom the SAME distance as a 630mm lense on a 35mm still camera? So, if at MAXIMUM zoom on the 630mm modified super 8, an OBJECT in the far distance would appear the SAME SIZE in the viewfinder as a 35mm camera outfitted with a 630mm zoom?

Is that what Mattius mean by: "the focal length remains the same and so does the zoom ratio?" That a 630mm zoom sees the same distance, whether it's on a Super 8 or 35mm camera?

So if I adapted a 200mm Nikon lense to my Beaulieu, I would essentially have a 1260mm Super 8mm lense. WOW, that seems like overkill. Does anyone realistically need that much zoom?

the lens doesn't become anything. it's still a 100mm. what björn is saying is the same same that i said, perhaps easier to understand but in words i try to avoid since it's always causes confusion.

in short, a 100mm lens on a 35mm camera results in a medium tele, while on 16mm it's more tele, and on super 8 it's *very* tele. when björn mentions 600mm (damn, i'm participating to the confusion anyway) he means that you get the same field of view with a 100mm on a super 8 camera as you would with a 600mm on a 35mm camera.

So if I adapted a 200mm Nikon lense to my Beaulieu, I would essentially have a 1260mm Super 8mm lense

noooo, you almost had it. you'd have "essentially" a 1260mm 35mm lens, which is "essentially" the same thing as a 200mm super 8 lens.

also, when i mentioned zoom ratio, i meant just that. a 6x zoom will always be a 6x zoom. that's all. the field of view at each end will change the same relative amount between formats.

sorry, me again. here's how i would approach it:

take the length you'd normally use on your 35mm still camera to shoot surfing from the beach. divide it by 6. that's the length you want to get the same amount of tele on your super 8 camera.

And consider from the other end of the format range. For a 4x5" view camera, 90mm is a wide-angle lens, normal is more like 150mm.
