All of Canons 50mm lenses lack something, maybe except for the 1.2L (which is in turn quite expensive).
The 1.4 is built way under par, and the dramatic difference between image center and corners makes it
easy to hate it. The 1.8 is an insult in its build quality, and the optically well performing 2.5 compact macro
is in desperate need of a better drive.
So yes, there is a lot of need for a new 50mm.
I still have a 1.8/50mm MkI, and I have the 2.5/50 compact macro.
The 1.8 is good enough for low light, and the 2.5 is good for general work.
Both are way from perfect.
1.8/50 with the mechanical build quality of the 1.2L at a price point of 350 USD or below would be a no-brainer.
Let's see what canon comes up with.
For the cost of the 1.2L it should be outstanding without any issues, but it isn't as there is a widespread issue of focus shifting and other focus issues.
I would love to see Canon release a decent 50 1.8 (~$250) and 50 1.4 (~$450) with good build quality and ring USM. Hopefully they'll come up with something along those lines.
How many times does this misinformation go around? I thought it wasn't an issue of focus shifting problems as it's part of the design to not contain a floating rear element to improve bokeh quality.
Anywho - I've owned the canon 50mm 1.8 II, 50mm 1.4, zeiss 50 1.4 and now the canon 50mm 1.2 - I can easily say that the 1.2 is my favorite out of the bunch with the zeiss coming in second (love that MF ring and build quality).
I'm not going to freak out on the 849 price just yet - we don't know if it's final, we don't know what that lens is including in-terms of build, optics, IS, etc - what's the point of freaking out just now?
I'm excited to see them finally updating it and I look forward to seeing what it brings.
