Why does my 24-105 have a different magnification (macro ratio) from a 105mm macro lens at same MFD?

Oh, I see. You actually have the working distance calculated automatically. Very handy.

I see how you zoom, but how do you focus the zoom lens?

For that lens Panasonic Lumix S 24-105mm F4 Macro OIS (and many others) you need to consult other scenarios. Normally I only have enough information to do zoom or focus and usually zoom takes precedence.
Look for the Previous and Next Scenario buttons.

Oh, I see. It's Scenario 4. Thanks.

Right that's the 0.5x for that lens

Nice tool. I hadn't really looked at it much before.

Thanks. Spread the word

It was a significant effort to code the ray tracer.

And it's a significant and ongoing effort to enter optical prescriptions (almost exclusively) from patents. For example I entered the Fujifilm Fujinon GF35-70mm F4.5-5.6 WR yesterday

If you're interested in hearing about new entries the best place right now is this dpreview thread .
