I just picked up this lens yesterday. Took it to my son's picture day for football and enjoyed using it. I am what I'd call an advanced amateur and this was my first lens purchase. I primarily shoot people so I find the depth of field this lens offers nice. Can't complain about the zoom either as I can now take photos of my kid on the field and get a lot closer to the action. I've read complaints about this lens being a bit slow to focus and I concur in isolated instances like lower light conditions and really close subjects. Be reminded that different lenses provide very different benefits and advantages. I've taken amazing photos with the simplest of equipment and have screwed up a lot photos with top of the line equipment used improperly. All and all, this lens was a great value and should be a staple in every novices bag ---
After hearing all the praise for Sigma's Art line of lenses I decided to purchase the 35mm and I could not be more happy with my purchase. It is sharp wide open and the bokeh is beautiful. I'll be adding other prime lenses from their art line to my camera bag.
This turned out to be a very nice lens for some one who is not an expert. It is much faster that all the write up I found on line and it is as good or bettern than my Nikon 70-300mm lens for my auto focuse filmed camera. the only thing is I should have gotten the VR version.
The 50 f/1.4 is my favorite when it comes to indoor and/or people photography. The lens is super fast and the IQ is amazing. I also own a 24-105 f/4 L that i use as my standard 'walk-around' lens and i think the 50 f/1.4 is comparable in IQ if not better. On a crop-frame sensor camera (my 40D) the 50mm translates to about 80mm which make it ideal for portraits. I would say if you need a prime lens for a long term this is the best bet. If you need a prime to experiment and learn then you could consider the 50 f/1.8. Bottom line - amazing lens and no complains whatsoever.
