I think the comment was in reference to Leitz stating that you should divide subject size by image size to get depth of field.
That's not what I wrote.

Which from a practical point of view is pretty useless. Most people don’t go out shooting thinking about the subject size and magnification but they usually are aware of the focal length and distance to subject.
I'm thinking that even rank beginners ought to have at least a rough idea of the size of the bird they're shooting.

Here’s one. Cheers
This is a lot more complete than whatever I have. Much appreciated!

And circle of confusion. (From Wiki)
The depth of field can be determined by focal length, distance to subject, the acceptable circle of confusion size, and aperture.[2] The approximate depth of field can be given by:

Yes indeed - the circle of confusion is an essential part of the equation. Most charts use 1/30mm for 24x36 format. Someplace I have a list of recommended sizes for all common formats, from 24x36mm to at least 4x5".

SuperflyTNT and frankraney -
Magnification can be determined by dividing subject size by image size. For the online calculators, you do need to enter both the focal length and distance. Note that the chart posted above does not mention either.

Four cleanings should be adequate.

You have to choose which folder the file is in. Next time, it should automatically choose that folder.

Someone posted this chart before (you?). I was skeptical at first, but the following calculator proves that depth of field is determined by magnification ratio and aperture. Still, many insist that focal length and distance matters.

They were going for about 100. US from KEH a few months ago, Ex+ condition.
Edit: KEH now lists the 5T and 6T for about 75. US each.

You've gotten some good advice here, and even some pictures so you now know what flowers look like. Isn't UHH just the greatest?!
