When I put rings (I have 3-ball rings) on my Nikon, the autofocus does anything and with the lens I have, I have a ridiculous depth of field. I have the impression that in this case, if I had clear eyes, the tips of the legs would have been blurred ...
And in video mode, it is the cat, because the mirror being reassembled, I only have the screen to focus on in manual mode ...
To sum up: I would like to be able to do a quarter of a tenth. I'm spending a lot of time right now observing ... 36 kinds of hover flies, bumblebees, hornets, wasps ... And I don't think I have a good photo or video ... I think came out of it honorably (just) by filming the wasps (without the rings; I was at the limit of the possibilities of enlarging my objective).
In fact the depth of field depends on the opening of your diaphragm.
Bill Brandt was working with a pinhead type opening ... says the legend.
Which allowed him to have colossal depths of fields

http://www.batcol.com/photos/brandt/index.htmlThe problem that results from it is all the same to get enough light into the lens to print the film or the memory card without going up in the asa or the iso and losing suddenly in quality ....
When it's a fixed plan (recently I had fun with garlic) it's easy: you have all your time.
When it's live animals you have to draw faster than your shadow ... or work in automatic, but I only work 100% manual, so you have to juggle quickly with the speed / diaphragm wheels ... and possibly the iso
Even with a Zenith you can have a good depth of field, it all depends on the conditions: brightness, speed of the subject.
You take a step, you close at 22, and suddenly you can lower your speed, or even ask and at 22 you will have depth of field for sure.
But hey, these technical challenges are a little gone from fashion to profit like this photo of Ms. with a blurred background.
So we do the opposite: we open a max (I have the 24/70 2.8 from Nikon) and we only target its subject without worrying about the rest: other times other customs.
