What's the first lens that made you say "Wow"

I mean as soon as you put it on your camera and started using it, within the first minute.
For me it was the 35L.

My Sigma 120-300 2.8 OS

For me it was the MPE-65. Wow!!

Sigma 50 f/1.4

135L

I would bet for many people it would be the 50mm f1.8. Sure once you use better lenses, it's no longer a "wow" lens, but for me, compared to shooting f5.6 on my kit zoom, and compacts before that, it was mind-blowing.

The one's that still keep me grinning, years later, are the Sigma 30mm and the Tokina 50-135mm.

Sigma 30mm 1.4

It was my first fast lens, Wow I loved being able to shoot in low light.

It was for me.. First time I used it the barrell fell out while I was focusing. The owner of the lens just picked it up and jammed it back in saying "it happens all the time" WOW!!

70-200mm f4L

Sadly, I have never felt that way about any piece of camera gear . . . and I have a 400 f2.8 IS.
I guess my expectations / demands are just too high for me to be "wowed" by anything
Wish I was more easily pleased - then things would be so much easier!

Tamron 17-50 (non-VC). Biggest mistake was "upgrading" to the VC version.

That's pretty funny, and not far off. Still amazing optic if you've never touched fast lenses or seen prime sharpness before.

50 1.8

Zuiko 50mm 1.4 it was a long time ago.

I think the problem is when you've plunked down the big bucks for a good lens, you expect perfection, dammit! So it is harder to be impressed. At least for me. It's more like, "whew, this is as good as I had hoped"

If you just borrowed a 400mm f2.8 for the weekend and had been using something much lesser (like, say a 55-250) then I imagine you'd be rather impressed.
