portrait zoom, limited range - does it exist?

I'm wondering if there's a lens out there, or if it's even technically possible. Something like a 55-80, f2.4, perhaps? I've been researching portrait lenses (going to be an uncle soon, and I'm the official family photographer). Plenty of primes in that range, and a few zoom lenses that cover it, but generally at a higher aperture. If there was a well made, decently compact lens for a smaller portrait range, I think it could be a real winner. Or, am I completely wrong and no one would buy it. Thoughts?

Tokina has a 60-120/2.8, which is a wonderful portrait lens. And is small and light weight enough as a 2.8 2X zoom

DA*50-135 f/2.8 is the Pentax portrait zoom. I don't have it but those that do say it doesn't get any better.

Yeah, I know, I've actually considered it. It's just big and heavy. I was thinking if there could be something closer in size/weight to the 20-40, it would be a good companion. But it might not be technically possible.

A lens for portrait means telephoto and wide opening (preferably larger than f2,8).

It's not very possible for zoom...At f2,8 there is lot of zoom, and many are a little big...

IMO, for the best results get a prime with a classic portrait focal length and zoom with your feet

lol, I know. For right now I'm probably just going to use my 50/1.8, since I have time before the kid is mobile. Doing all the research just made me think that maybe I was missing something.

Yes, the 50 is great for portraits. For headshots, a 90mm or 100mm macro lens will do wonders, if you have one.

Either get a prime (FA 77, DA *55, Sigma 85mm f1.4) or the Pentax 50-135. Those are really the best options out there from a portraiture standpoint (well, you could get a 70-200 f2.8, but if you think the 50-135 is big, those are bigger).

Tamron 28-75 f/2.8 is an excellent portrait zoom. check out this thread for images:

I love my 28-75. I also love my 50-135. The 28-75 is much more useful in small spaces than the 50-135. (I was going to say "indoors" but a basketball arena might technically be indoors. The 28-75 is much more useful in a house. You can take a photo of a kid across the room and get more than the head in the frame.) If you're taking group photos (as the official family photographer), it's wide enough to do a good job without distorting people near the edges excessively.

Both the Tamron 28-75 and Pentax 50-135 are fine portrait lenses. The 28-75 is more versatile with its wide end, the 50-135 needs room. Understanding exposure, lighting and composition is more important than any lens.

Have you actually handled the DA*50-135? For what it offers I find it neither big nor heavy, and it is the perfect one stop portrait shop for K-mount on a crop sensor.

If you really need something faster and smaller, suck it up and take Adam's advice; buy a FA77 and be prepared to hoof it a bit.

Sounds fair; every possible focal length from full body to head shots.

It's been a while, so I probably should look at it again. The thing is, my usual photography style is wider. The portrait lens is something I'd like to keep in my bag, but it's more likely to be used at family events every couple of months. So for that, smaller and lighter is a plus.
