Hi everyone,

Now I know this lens has been around the block for quite some time. And for the purist, this is at best a decent run-and-gun lens for a R16 camera. However I might be using it for a smaller project soon and I am having issues finding information about the lens.

More specifially the aperture.

I know it is a variable one, but when does it move? Because physically the two lenses I had access to use, both have the aperature at F/1.6 over the whole zoom-range, physically. So planning a decent exposure is a lot harder.

Now I know I can lock it to F/2.2, but in this scenario I would love yo be able to use the full speed of the lens.

Appriciate any input.

//C

You should test it on a digital camera with a waveform monitor

This is of course one option...

That lens is T1.9 (f1.6) up to 12mm. From 12mm it is reduced gradually to T 2.5 at about 45-57mm. I'm basically quoting from the 16mm Motion Picture Camera Help Book by Douglas Underdahl (1989).
