Depth of field problems

Hi,

Is there any way to increase the maximum number of units? For instance, in a centimeter unit setup from Max, Vantage cannot focus more than 10.000cm. I guess the limitation is the maximum number, not the actual distance.

Also can you add a functionality to the depth of field, where we can see the aperture size in terms of f-numbers like 1.8, 2.8, 4.0 etc., like in real life lenses. It makes a lot more sense for people who are accomodated to photography.

Thank you in advance

Cheers!
