I've seen some really good images from iPhones but I'll take my 10 yr old Canon PowerShot G3 over any of them, any time. Most phone photos I've seen look like marginally better than webcam quality.

Firmware does not change the sensor. Raw images have little manipulation in camera, its all in PP. The jpeg images might be better, but I do not use jpeg.
This is a misnomer if / when comparing against the 5D Mark III FF camera.
I'll add in a vote for the 100 f/2.0 as well (if only because i've got one).
Could you share the information what ps trick or 3rd party software is supposed to remove banding noise? I'd really like to have it in LR, but I've got some pictures that needed shadows raised a lot (high dr shots with moving objects) and that I'd really like to postprocess to a usable state?
There are a few ways you could do it. The simplest would be to take a bunch of dark frames of the same exposure time as the image you wish to remove that kind of noise from. Blend those frames together in something like Photoshop to create a single pattern noise frame. You want to stack them in some kind of additive way to enhance the effect of the noise.
To remove that noise from a photo, you can do so in Photoshop. Just blend the noise frame with a "difference" setting, then adjust the opacity to tune the degree of noise removal. Keep in mind that the way pattern noise exhibits is dependent to a certain degree on exposure time, so you'll need to create a dark noise frame for a variety of exposure lengths for this trick to really work. You don't necessarily need a noise frame for EVERY shutter speed, but if you frequently use 1/15th, or 2 seconds, etc. then you'll want to make a noise frame for each of those exposure times.
Its not perfect, some pattern noise (FPN and HVBN) will remain, but you can eliminate a lot of it that way.
You can also use one of the more advanced noise removal tools on the market. They keep getting better, and some are pretty good at removing pattern (including banding) noise.
.. You can easily create a bias offset frame to remove FPN/HVBN, ..

Did you also read up on fringing/CA on the 85 1.8? Yes it's incredibly sharp and has great DoF bokeh but the purple monster made me sell my copy. I'd rather have the 100 f/2 and the 135 L. of course.
