When it first launched it was a pretty reasonable price, but it has gone up a couple times. I agree it is a bit spendy, but one cannot say that this lens is lacking in character. It has a very distinct look all to its own.
I agree that a 50mm does pair very well with a 20/21mm lens (also a 24/28mm), but I'm weird in that I like to pair 35mm with 50mm.
These days though I'm on the same page as you, I'll take my canon 20 with the Zeiss 50, and the 35/135L is a separate combo
Actually I am not sure what to do with 35L. I believe i am still gonna keep it for a while but i am leaning toward selling it and just having the extra money... as much as i love it.
And yes, the character of planar is worth every penny. Took a quick portrait yesterday at 1.4 and 0.8m distance, something magical.
BTW the flower shot has not been edited in any way, just Lr -> jepg
