Is the Canon EF50mm f/1.8 II lens considered a macro lens? If not, what makes a lens a macro lens?

thanks in advance!

No - A lens has to have a magnification of 1 to be classified as macro, in comparison the EF 50 f/1.8 has a magnification of only 0.15... (i.e. 1/6 life size vs 1:1 for a 'true' macro)

See the chart: http://consumer.usa.canon.com/app/pd...FLensChart.pdf

NHL of course is correct, but I believe Canon has a life size converter for their 50mm macro, although at an extra cost, and also an extra piece. I have the Sigma 50mm macro whichis a 1 to 1 true macro, and it's a pretty good lens, but I would like a little longer lens for macro.

But also be aware that for close up shots you don't always need true macro.

This shot was taken with the 50mm f1.8 II.

peripatetic is quite right of course, but I would choose a longer lens from the above lens chart, such as one of the telezooms which has a higher magnification (1/4 vs 1/6 life size) for larger close-up - Here's one example from a 300mm perspective instead:

Its too bad that the 50mm f/1.8 isn't a 'macro'but I still consider it a lot of fun close up and the results are not so bad as to be embarassing. You do need to add a set of Kenko extension tubes which will allow focus a bit closer than 1:1 (filling the frame with something about 10mm across).

I agree that many macro subjects (certainly butterflies) benefit from a longer focal length but there are places in the flower garden that you benefit from being able to work in tight spaces so 50mm is not all that bad. I suggest playing with the lens to determine if you really like macro and then buying a 150mm (or other) macro to augment your 50mm capabilities if this turns out to be your thing.

Almost everything in the gallery used at least one of the three tubes. I made this 'aid' to show what you get with various tubes.



Note that the lens alone will get whole flowers of larger types like this lily but little things and details need them.
