The EF-S 24 was praised in advance in many forums and I have to say - not without good reason. Tip.
Of course, the initial enthusiasm that you now 38.4mm effective focal length on an APS-C sensor.
But everything else, AF speed, AF accuracy namely, AF in video quietly and briskly mitrichtend, Focus, bokeh effect awesome due 16cm minimum distance, compact, ... WOW!
The 70 works now under way as a "compact" (hopefully they hear not) hehe.
Brings For the price, the greatest EF-S Fixbrennweiten Canon lens currently which you can actually call the Always-top with a city tour, greatest performance in portrait photography and is not to exceed in compactness and weight.
From me a very clear recommendation! Where is the thumb like it :))
