Tamron Kit lens @ ADORAMA

can anyone tell me if this is a good kit lens for my K100D and @ $209 for the kit is this a good buy? i am basically in the hunt for a nice and cheap macro zoom lens although my K100 came with the 18-55 kit do you think having the 28-80 is better than my pentax 18-55 kit?

the kit lens i am taking about is:
Tamron Twin Zoom Lens Kit for Pentax AF Film Cameras with 28-80mm f/3.5-5.6 Aspherical & 70-300mm f/4-5.6 Di LD 1:2 Auto Focus Macro Lens.

I've tried a Pentax Powerzoom 28-80mm (F3.5-4.7?) lens on my K100D for a few days and I found the extra reach to be a nice to have feature. I think the Tamron is has a smaller aperature (F5.6 at 80mm) at the long end but the results should be comparable.

I still like the wide angle of the 18-55mm kit - it helps with larger groups in a small space. The 28-80 will not open wide enough and you will have to take quite a few steps back. So I would say, check what you are shooting.

Increative started a thread about 70-300mm lenses from Sigma and Tamron and from what I've read and seen it is surprisingly good.

Hope this helps.

I don't have that first Tamron lens, but I would have to say that the 28-80 focal length wouldn't be much of an upgrade for me. I've got a fair number of shots out of the kit lens at 20-23mm, and I'm more of a fan of the wide angle. 28mm works better on a film SLR--I put a Pentax 28-80 through it's paces there.

i have tried two cheap sigma lenses.. one an older 28 x 90 (ebay) and the other a new 28 x 80.. the new one cost me 30..

both are remarkably good lenses for the money and both do a very nice 1:2 macro.. 1:1 with 4x close-up on the end.. thye also work well with kenco 1.5 x tele converter..

bit of joke when i think what new tamron 90 or sigma 105 costs..

some example shots here

I have never tried the Tamron kit lens.. The Sigma one I did own and it was a very poor lens in my opinion.. It worked well enough stopped right down f8+ but so does a coke bottle ;-)

Anywhere near wide open it was soft, ok for 6x4 prints, but bad for large prints and for cropping.. More importantly had very bad distortion and vignetting.. If you want a cheap lens from 28-xx I wouldn't suggets even the Pentax old 28-80 kit, I think the better cheap option would be the Pentax Powerzoom 28-105 4-5.6, I got one very cheap on ebay that was actually new.. they pop up from time to time, and always plenty of Second Hand ones around.. I sold mine when I upgraded (mainly for speed) to the Pentax 28-105 3.2-4.5 but Mo still has one and I'm sure if you ask him he could point you to samples..

i think ur better off getting one of those all in one lenses...IE an 18-200 or 28-300

my 2 older lenses are similar to the kit lens you want (but sigma) 28-80mm 3.5-5.6 (1:2 macro @ 80mm) and a 70-210 mm....

both are OK...but..I hate the fact that i have to swap lenses all the time...(considering on buying an all in one zoom as a walk around)

to be honest...I have hardly used the 28-80...(unless I want to do some sort of macro) and the 70-210 gets soft in the higher focal lengths...

the kit lens works for me majority of the time.....

Yes didn't think of that, the Sigma 18-125 I had was definately better than the Sigma 28-80 kit I had...

i have the tamron 18 x 200.. not the fastest lens on the planet at 200mm but i wouldnt part with it.. its my mainstay general purpose lens..

i have tried the 28 x 300.. and a tokina 35 x 300.. but i went for 18 x 200 and a 70 x 300 for the long reach end.. the big overlap means less lens swopping which i dont like.. the 70 x 300 just works better (more usable) past the 150mm mark..

look here...

I've seen several posts asking about inexpensive long zooms/long zoom macros, including questions about the Sigma DL or APO 70-300mm 1:2 macro lens.

I've got the Sigma DL and it is actually a decent lens for the price. It has a 1:2 macro at 300mm, which is the reason I got the lens in the first place. Don't expect miracles from this lens, but I can't say anything really bad about this lens considering the low price it sells for (<$100 used on flea-Bay).

Here's a good link to DPR discussing this lens...
