Since it's in the 35mm subforum, I'll say yes. My favorite is the Cosina-Voigtländer 21mm Color-Skopar which sits on my Bessa-L. It's a wonderful little superwide lens, and well worth the small additional price of a Bessa-L if you haven't got a Leica thread-mount camera already.
Under 35mm category, would be the Summicron-m 35mm. When I first bought it, it took a while to get used the massively increased contrast compared to (all) the other lenses I've owned. Esp on B&W. Colour is just unreal.
And sharp as Kevin Spacey in 'The Usual Suspects'.
To have all that on a lens this versatile is great. And it's fast enough for me, on a rangefinder.
Pentax Super-Multi-Coated 50mm f/1.3 screw mount (M42). Sharpest lens I've ever owned. The glass has a slight tea coloring to it now, but it does not seem to matter. I'm a Canon fan - but no matter, the Pentax is sharper than any of my Canon FD or FL mount glass.
Actually, a lens that I just bought three months ago. It is a Nikkor 24-120mm F3.5-5.6D AF-S VR Zoom Lens. It's a great Vibration Reduction lens. The only thing irritating about it is that it is that the hood is a pain - when mounted, it is difficult to rotate a polarizing filter, when mounted in the storage position (that is backwards), it is difficult to zoom. You pretty well have to take the hood and leave it in your pack when it isn't in use. From my initial uses, it is very sharp, great contrast. Also, being a G lens, there is no aperature ring.
I tend to like Canon NFD 28mm F2.8 lens a lot. It's compact and light-weight, and sold dirt-cheap, but optically excellent. It's very high-res with good contrast and sharpness, and there's no apparent distortion on the images produced by it.
Very interesting choice. I would have assumed that any "serious" photographer would choose a prime lens. Nice to see that all aren't so pedantic.
In my case, it is more that 35mm isn't my primary format, and I don't want to be bogged down with equipment for it; especially when traveling. Although, I have always used a zoom lens of some type, even before I started doing LF.
