28-200 Super Zooms?

With the 18-200 and the 18-250 flooding the marketplace I'm starting to see a bunch of 28-200mm zooms appear on ebay. Here is a Tamron one:

Tamron 28-200mm f/3.8-5.6 AF LD (IF) Lens 4 Pentax DSLR - eBay (item 190224065125 end time May-28-08 12:27:27 PDT)

How are these lenses? Everyone seems to praise the 18-250 but it seems that these 28-200 lenses may be a good daytime walk around lens. Any input?

The Pentax SMC-FA 28-200 is very good in my experience.

You have to be prepared for the wide end not to be quite wide enough though, on the dSLRs.

IMO the 28mm def is not wide enough for a 'do everything' lens. 18 - 250 is excellent. I'd save your money.

I do own 28-200 from Tamron. It's a decent lens. I don't see problem in 28mm because I always carry Sigma 10-20 with it. But generaly I have love hate realtionship with this lens. It covers quite useful range, but it happens very often that it's not either wide or long enough.
To get good results you have to stop it down (as usual) and it's slow max. appertures don't help. It' pretty good lens to go to town for street photography. And with ultra wide angle, it's a great combo. And outdoor it makes good portrait lens too. For the prices it goes now, I wouldn't hesitate to get one, if you're after lens, that will be staying on your camera for most of the time. For walk around though, something like 10-20 or 12-24 is must have with this one...
It could be bit sharper, but generaly, it's one useful lens.
here is few samples from it:
PS: one more thing, it's FF compatible, so if you have film body, or Pentax will release FF D body, you will want to get this one.

The Tamron 28-200mm that I have is not marked DI or anything, it's just a 28-200 f3.8-5.6 zoom that was the prior generation to the one that's still available (I think it's XR or something like that). I originally bought it for my P3 and I was going to sell it as I switched to digital, I figured it wouldn't be very good since it wasn't a "Digital" lens. But before I sold it I tried it out, and it was very, very good for a wide-range zoom, almost as sharp as my Sigma 18-50 f2.8 EX (which has turned out to be surprisingly good). It does have a few drawbacks:

1) It underexposes by about 1/2 - 2/3 of a stop with available light or flash. I don't know why, but it does this regularly on my K10D and my K100D. I don't worry about it and dial in +1/2 stop and review my images to check exposure. This may just be my particular sample.

2) The 28mm end that seemed fairly wide with 35mm film, is not very wide angle at all due to the 1.5x crop factor, so you do need something wider. I used the 18-55 kit lens for that until I upgraded the kit lens.

3) Like other lenses of this type, it does have a (fairly) small maximum aperture.

Personally I would recommend one if you need the range, can live with the 28mm limitation and small maximum aperture and can get a good price on it.
