I think most of the images posted here was meant to show what the lens can deliver, not the skills (or lack of skills) of the photographer. At least that was my intention. So, from that perspective, the quote from distant.star is quite relevant.
Every time I get one of the images from this lens up in LR, I´m trying to figure out whether I could have the same IQ with one of the other (and much cheaper) lenses. And, after a fair number of shots, I am confident that this lens outperforms every other lens I have seen. The 4MB limitation for these posts reduce the IQ a bit, so for you who would like to see the full performance, it is well worth getting access to some images in full size raw format.
For the record, I am in the camp that believes you cannot substitute for great equipment. Great equipment will not make a crappy photographer a good one, but it can certainly make a good one better and a great one truly remarkable.
But I'm still not buy this lens.
That being said, do you have any photos that you've taken the same shot with the Zeiss and with the next best option that you can share. No doubt these images look good, but like you I'm curious if/what the lens delivers that can't be gotten elsewhere.
