Focal length change from 4:3 to 3:2 with Lumix FZ 50

Recommended Posts

Hello, dear colleagues !

I have a question that I don't get thought through as a non-Mathe genius:
If I change the image format of my FZ 50 / Leica V-Lux 1 (1/1.8" CCD | focal length equivalent KB 35 - 420 mm) in the camera from 4:3 to 3:2, does the (apparent) focal length also change? So I have the purely subjective, obvious feeling that I get a little more wide-angle at 3:2. Is that right, or am I wrong? So maybe 33 mm instead of 35 mm. And how does the 3:2 masking at the long end behave at 420 mm? Please do not offer conversion formulas. I am really too stupid for that. If possible say if and if, how the focal length changes to which value.

Can anyone help me? That would be really nice. Thank you!

Changing format does not automatically change focal length unless you separately change the lens zoom setting.

Thank you, David !

In the meantime a user in the german part of the LUF showed me a website, where a specialist told the same as you answered to me. Must be right.
So it would make no matter changing the format on a FZ50 /V-Lux 1.  The only change is the pixelnumber. Only 8.5 MP with 3:2  to 10 MP when using 4:3.
And this really does not make sense ;)

It does make sense if you consider that the 4:3 format actually uses a greater area of the sensor than the 3:2 format, hence - more pixels. If you used the 16:9 format, pixel count would be even lower. 

Cheers, 

Jan
