NONE of your images above are macro-photographs. All are close-ups.
The butterfly can be cropped much tighter, and the bees cropped to macro proportions.

Bret, thanks for looking. I have been watching this site for quite some time now and admire your work.

Nikonian72, please excuse my ignorance. I still am not sure how a close-up and a macro differ. I know a macro is at least 1:1 but how can you tell if what you are shooting meets that requirement? I see you cropped my photos much tighter and they maintained the same quality of resolution that they had previously. I used a Tamron 90mm with a D7000 and was approximately 10 inches from the bee and maybe 24 inches from the butterfly. In other posts, I have read that simply cropping a close-up does not make it a macro yet you seemed to imply by cropping my photos that they are now macros. I am missing something. Would you be so kind as to enlighten me? Many thanks in advance.

1.) turn-off Auto-Focus;
2.) adjust lens to closest focus, know as Minimum Focusing Distance (MFD);
3.) select photo mode (Aperture priority, Shutter priority, Manual);
4.) move entire camera/lens combo in-&-out toward subject, taking photo when image is in focus via eyepiece;
5.) note Working Distance (between lens front element & subject).
To capture true macro with a 90-mm lens on a Nikon body, WD is 135-mm = 5.3-inches. Any farther away is a close-up. MFD results in minimal DoF. I tend to shoot a bit farther back (better DoF), then crop to macro proportions. 10-inches will not capture a true macro image, but is crop-able; 24-inches is definitely too far away for macro.

Had YOU cropped & posted your images as I did, no one would ever suspect the bees were shot as close-ups.
I defy anyone to discern the difference between captured macro and cropped-to-macro images.

That makes complete sense. Thank you for taking the time to explain the difference. What would be the benefit, if any, if I were to use a set of extension tubes with this 90mm lens? Would it enable me to work at an even closer MFD?The best way to see true macro is to: br 1.) turn-... (show quote)

Extension tubes will reduce WD and increase magnification. Most often used with very small insects, like aphids, or isolating a dragonfly's head, etc. Unfortunately, DoF is also reduced.What would be the benefit, if any, if I were to use a set of extension tubes with this 90mm lens?

P.S. - Macro-Photographers are more concerned with WD than MFD.

I enjoyed your explanation of macro. thanks everyone for the pictures and the explanation.

Great info on WD and MFD.
Does it mean that it is preferable to use a 180mm macro lens versus a 90mm or a 105mm ?
Both the WD and the MFD will be greater, so it will not scare away the insects.
I am looking at a 90 mm and a 105mm ( and possibly a 150 / 180 mm macro lens ). Not sure which one to pick yet.

Minimal WD with a 180-mm macro is 270-mm = 10.6-inches to capture 1:1.
90-mm macro lens yields 135-mm WD = 5.3-inches to capture 1:1.
