Besides the EF 85mm f/1.4L IS, What are the Other 3 Lenses Coming?

With a full frame sensor DSLR, 40mm may be about the shortest focal length where a pancake design can be used because of the need to allow clearance for the swinging mirror. With shorter focal lengths a retro focus design would be needed, leading to a larger lens.

That was kind of my understanding as well. However the Voigtländer 20mm caused me to question that a bit. How did they pull that off? Or are the softer corners part of the compromise?

Actually that 28/1.8 USM is a nice lens. I've used it on my 7D as a standart walkaround lens. On APS-C, the quality is good to very good from f/2.2-4 and build quality is also very decent with no moving parts, fast and silent AF and overall compactness and rigidity. But I sold it, when I purchased 24-70/2.8 II - apart from wider aperture, there is no contest. With 85/1.8 USM I've had nothing but bad luck. First copy was a dud and second one was not focusing reliably (on 7D). But as you said - both lenses are still relevant with only CA as a major weakness (and that 28/1.8 has a rather mushy corners on FF wide open as well).

Sounds like we used the 28mm for very similar purposes. It was my "normal" prime on crop and I used it a ton on a T2i and later on a 70D. I disliked it at f/1.8, but just stopping it down to f/2, f/2.2 did wonders. I'm sorry you had a bad experience with the 85mm. When I was still shooting crop, the purchase of the 85 is what made my 70-200 collect a lot of dust (for shots of the kids running around outside, etc.)
