Hi, I'm looking for some standard lenses for 16mm but I'm not really sure what they are. I bought an Krasnogorsk3 whit M42 lens mount. I'm am an 16mm rookie and I don't really know, what standard lenses in 16mm are. Is a 25mm lens a standard as in 35mm a 50mm lens? What about a wide lens? Is it a 9mm? I'm glad if someone help me? Is there an webpage where 16mm technicals are explained? Thanks a lot. Greetings from Germany

Hi Alex!
for calculating the focal lenght of a standard lens you have to square side a of your frame and add the square of side b. From this gotten figure you extract the root and then you get the focal lenght in milimetres. Unfortunately I can't tell you the size of a "Normal 16" frame, I really can't find the size of it.
For example in 35mm: Side a is 24mm, side b is 36mm. >
(24mm)²x(36mm)²= 1872mm² >
After extracting the root:
43,26mm

Best regards from munich,

Toni

So, "Normal 16" is 10,3mm x 7,5mm. A standard lens has a focal lenght of 12,7mm.

Hmmm... I think I've heard that 25mm is the standard focal length in 16mm. 12mm is pretty wide. Standard configuration is a 10mm (wide) 25mm (medium) 50mm or 75mm (telephoto) or a zoom which can do them all.

The zenitar m 16mm 2.8 works great with the k3.
For handheld it's almost like it was made for the camera.covers the full super 16 frame if you decide to widen the gate.

Use a fountain pin to push the auto exposure pin into the body of the lens so that it stays so you can adjust exposure manually.
