Okay my bad it is 106mm on the P25 and on a P30 it is 118mm in respect to FF 35mm

The following are the same* as using the new 150mm f/2.8 lens on a P30/P21 (1.3x factor):
A 150mm f/2.8 lens used with a P30/P21A 189mm f3.5 lens used with 120 film
A 118mm f2.2 lens used with 35mm film (or FF dSLR)
A 417mm f7.8 lens used with 4x5 film
The following are the same* as using the new 150mm f/2.8 lens on a P45/P25 (1.1 crop):
A 150mm f/2.8 lens used with a P45/P25A 170mm f/3.2 lens used with 120 film
A 106mm f/2.0 lens used with 35mm film (or FF dSLR)
A 374mm f/7.0 lens used with 4x5 film
The following are the same* as using the new 150mm f/2.8 lens on a P65 (1.0 crop):
A 150mm f/2.8 lens used with a P65A 155mm f/2.9 lens used with 120 film
A 96mm f/1.8 lens used with 35mm film (or FF dSLR)
A 341mm f/6.4 lens used with 4x5 film
Hope that clears things up; I know the numbers can start to get dizzying. I used our [a href=\"http://www.captureintegration.com/tools/our-tools/]Focal Length Equivalence Calculator[/url] (though I used a pre-release version that includes aperture equivalence).

*obviously sharpness, bokeh etc of any lens made to these specs will vary widely; there is a huge difference between a lens which is relatively sharp wide open and one which is nearly unusable wide open[/span]
