I want a 50 mm that is sharp in studio light and outdoor light for portraits, I find the 50L to be inconsistent. It always renders a nice colour and has nice bokeh but that isn't enough. I'm finding my sigma 35 to wow me to the point I hate my 50L in terms of sharpness across the board. It gives me a way better punch to my photos. So if this 50 coming out has that same punch and focuses better then the 50L then sign me up. I'm starting to really like the colours my sigma 35 produces it gives it a vintage glow, maybe doesn't have the same bokeh as the 50L but bokeh is overrated.
I realize there are a lot of 50L lovers on this very forum, and that the 50L is more for the draw, bokeh, color, etc. than pure corner to corner sharpness.
But there are a boatload of people who want sharp 50mm performance at something wider than F/4. So, in fairness, I baited that response. I know you folks are out there.
And bokeh is pretty damn subjective.
In a voter-blinded 'study', the Sigma 35 F/1.4 beat the Canon and Nikon 35 F/1.4 lenses for best bokeh here:
Granted, Kai is many things -- but not a scientist. The poll itself is nutty, but it's a data point nonetheless.
But I'm getting OT. I just wonder if the new Sigma 50 will perform like that 35...
