Crop Factor Converter

[chrisk121]

Hello! I was playing around with excel and I thought of something. After about five minutes of work I made a Crop Factor Converter. I don't know if this has been done before, but when I searched for it, nothing came up. If it has been done, or is against the rules, you can remove it.

Here's a preview http://www.divshare.com/img/display/1513117-7e3.gif

You can download it here http://www.divshare.com/download/1513118-643
You need Microsoft Excel 97 or above to use this.

Instructions

Under crop factor, type your crop factor.
Under Lens Wide Angle (mm) type the widest angle your lens can go
Under Lens Telephoto (mm) type the longest focal length your lens has.

Your 35mm Equivelent Wide angle focal length will appear under 35mm Equivalent Wide Angle (mm), your 35mm Equivalent telephoto focal length will appear under 35mm Equivalent Telephoto (mm).

For prime lenses, you only need to use one box. Wide or Tele will work fine.


Enjoy!

I don't mean this to sound offensive... but I can do this in my head. It's not that hard.

Sorry, but I don't think anyone's likely to use that. I for one just need a rough guide in my head and times by 1.5 and that's accurate enough for me. All crop factors on cameras (except Canon) are 1.5 which is easy to convert. I don't see how a simple excel file would make it any easier. I think even the oldest phones have a calculator if they want to work it out exactly.

I know, I was just bored.
