LPR setup help

Ok, potentially dumb question, but... lol..

I have the 5-60mm lens, and am debating getting the z4 8-32. If I wanted to get a ball park estimate on what the 8-32mm lens would look like by using my z2 5-60mm, what would I set the zoom at? Say the 5-60 goes from 0-2000, would it be somewhere around 900, or?

I'd really like to get an estimate rather than just buying a z4 out of the blue. I could definitely use it for yard/sidewalk faces, but...

Thanks
 
Use this:

 
From my experience with both, I'd say the Z4 zooms in roughly about 1/2 of what the Z12 does. BUT, the 1/1.8 CMOS on the Z4 picks up the plates in a readable way, further away and in a more forgiving manner than then the z12 i had in place.
Which the allows me to see the whole vehicle and the plate during the daylight hours. Whereas a fully zoomed Z12 in my experience needs to be relegated to 1 job to succeed in its mission. And it really shouldn't be asked to do double duty.
