    Cons: Still heavy

    Pros: Worth it\'s weight in gold!

    Summary: Just an update: I\'m still in love with this lens! It\'s shot weddings, landscape, portrait, wildlife, action sports, astro. The best part is how much it\'s reduced my need to clean my sensor because I barely ever change my lens anymore! haha. Sounds cheesy but I\'M IN LOVE!

    Cons: Kinda heavy...

    Pros: Value Incredibly sharp Beautiful color Nice round bokeh Dust and splash proof Clean Edges Optical Stabilization

    Summary: This is my firs Sigma Art series lens and I am not disappointed! In fact I am as far away from disappointed as I\'ve ever been! Aside from it\'s mass, the only thing I have not liked about it is how long it took to get one after it was announced back in February, but not only was it worth the wait, it\'s also worth the weight! HA! (See what I did there!?) To test, I ran a side by side with my Nikon 50mm 1.4D, rated as the sharpest 50mm prime under $1000 and 4th sharpest 50mm on DXOmark. If the Nikon was sharper at 50mm it was too little of a difference to notice on my D600. It\'s only a 24 mpix sensor, but that\'s at least enough to say in no uncertain terms that the Sigma Art lens, as a zoom produces just as sharp and better color than the prime. The bokeh is perfect, the head on flare is beautiful, and the Optical Stabilization system is superb! I was consistently shooting tack sharp images at 1/10th of a second exposure at 70mm, standing, hand held with no elbow rest. I love this thing!
