well my main question is what are the technical differences of thoose two? the obvious technical differences are clear slight range difference and rather big (lichtstaerke 1:1,4 part, don't know the english word for that, yet!).. but what makes the efs a macro lense and wheres the difference to the ef 50? from a price range they are pretty similar. and so faar i see advertising for the ef-s that says its a good portrait lense. there needs to be something really different here which i don't get (as an newb)

any help would be appreciated

thnx in advance!

The difference is in the magnification: the macro lens has a 1:1 ratio while the 50mm f/1.4 has a 1:6.5

-> They'll both do portrait, but the f/1.4 aperture will be brighter and have a shallower Depht Of Field when wide opened.
The macro lens can take a closer image like zooming in on the eyeball/eyeslash only for example while the f/1.4 can't because of the limited minimum distance.

My 50mm f/1.4 has considerable CA outdoor and IMO the macro should have better control over this issue...

CA - Chromatic Aberration...

Check theses blue fringes in the bright areas:

hmm thats interesting.. is this CA due to the 50mm's aperture or is this caused by something else?

Normally I've never noticed this CA - This shot was taken in an unusual situation (wide opened in bright light/bright object). Indoor wide open where this lens is used most often, I doubt anyone will run into this issue.

-> Also remember this lens is designed almost eon ago, way before 'digital' EF-s come to being
