Re: Super A

fixed to the 'lens is fully open' position. Problem is that the rest position of the aperture-simulation pin on the body is the 'lens is stopped down X stops' position, where X is something like 7 or 8. So the meter reading would be quite wrong without this ... cheerio ralf

Re: Super A

lever is unaltered, so it still 'tells' the camera that the lens will be stopped down further during exposure. Hence the meter reading drops. I see no obvious way to circumvent this with mechanical DOF preview systems. cheerio ralf -- Ralf Stubner <mailto:[EMAIL PROTECTED]> - This m

Re: FW: focal lenght

losest focusing setting your lens allows and take a picture of a ruler. Afterwards, you photograph all flowers at exactly this focusing distance and compare the image size of the ruler with the image size of the flower. No need for math containing unknown variables ... cheerio ralf -- Ralf Stubner <

Re: Anyone want an 85/1.2 ?

right that the mount is screwmount M42, and that there is no aperture > diaphragma? Yes, it is M42 and there is no apperture diaphragma. Also, this lens is said to cover the 35mm frame, but the image quality in the corners is supposed to be quite bad. Whereas the center is supposed to be v

Re: How does a TC work? (Was: DOF with and without 2x TC)

ng, so I just tested it with my f/1.4 50mm and my 2x TC, and indeed, there seems to be an increase in DOF when the total magnification is kept constant. cheerio ralf 1 Simply put a TC is just a diverging or concave lens, in the same way that a normal lens is just a converging or convex lens.
