;D ;D ;D Good one! ... when I read the title I thought you bought a ZEISS lens that did not live up to its name.

At least my endodontist uses top-shelf equipment
As far as Zeiss, I did just return the Sony/Zeiss FE 55 mm f/1.8 when I returned the A7R. The lens was sharp as heck, but I did have one issue with it. It's minimum focus distance was a pretty far 50 cm with magnification of only 0.14x, which was a hair too little for close-ups or near-macro's ("ring shot").
I guess I'm just spoiled by my EF-M 22 mm, which can do 1:2(!) macro at 15 cm and even by my 35 L which can do 30 cm at 0.18x, which was a big difference in practice.

That reminds me to ask you, I hear a few people say that the FE 55 f/1.8 has a bit of vignetting wide open, is that correct? if yes, was it too much or acceptable?drjlo said:

FE 55mm has -1.6ev vignetting, which is same as Zeiss Otus 55mm per DXO, somewhat heavy for a $4K lens but not too bad in real life shooting. First photo is FE55 at f/1.8 without ACR vignetting correction, second photo with vignetting corrected.

It no doubt rendered the colors of your root canal procedure in a certain "warmth" without being artificial, and made the surgical area really "pop" in a way that cannot be measured or even expressed in words. I'll bet that intangible "something extra" made all the pain and expense of the root canal well worth it.

"When Zeiss Glass does warm the heart…or at least, the cultured human cardiac myocytes in the lab this afternoon. "
So, being curious I did a search on Zeiss LSM 510 META. The Zeiss site sent me to a page for the LSM 710! Can I conclude that the LSM 710 is a newer model than the LSM 510? It would do both my mind and wallet good to learn that even Neuro has to deal with older generation equipment from time to time!

With apologies to your mind and wallet, we just ordered an LSM 780 to replace the 510.

I've had three root canals. One became infected while the temporary cap was in place and waiting on the crown. I left on a 4 day trip to dark country for astronomy the day after the root canal and spent the time in wonderful pain. For another root canal, I arrived in the morning and the receptionist told me I'd have to reschedule as the compressor that runs all the air tools had malfunctioned and they were having to cancel and reschedule all appointments. I offered to take a look at it, got it running in a couple minutes. After the procedure I came back to the receptionist to cover my copay portion....the dentist walked over and said, "Are you kidding? If you hadn't fixed that we'd have had a scheduling nightmare and lost an entire day's work! You don't owe anything."

I'd be more concerned that you've got a piece of equipment called (what looks like) HAL 100 on your desk.
Only a few more upgrade cycles and you'll be at 9000.
