Hi dcshooter,
Thanks for the advice. What are your feelings about the ratings on PF? Does it compare well to the other lenses with similar range.
The ratings are similar to the tamron and sigma that cost so much less, I am not sure why.
Thanks,

Originally posted by rkappleby I have that lens and its awesome - some of the negative comments are related to price and weight - I paid considerably more than $450 myself. The majority of the overall rating are 9 and 10s one rating of 5 skews the ratings and there is always the possibility of a bad copy. Can you test it first?
Hi rkapleby,
Thanks for the information. I noticed the 5 rating also, and agree that the low rating skews things. But I see that happening often in the user ratings section.
Many of the other lenses reviewed offset that lowballer with high ratings. The 24-70 has a 9.5 with over 50% of the ratings a 10.
I notice that the tamron and sigma in the 17-50 and 17-70, etc are scored very similar to the Pentax 28-70 despite the much lower prices.
Probably 2 big factors are the higher price and weight like you said.
Thanks,

Originally posted by Adam Unless the price of the 24-70mm is prohibitive for you, I'd go for the newer lens. Considerably wider and better IQ all around, plus silent AF and access to quick shift. I wouldn't say the difference is as dramatic as the D FA* 70-200mm vs the FA* 80-200mm, but it's definitely there.
Note that most user reviews of the 28-70mm are for APS-C, where it performs quite well.
Hi Adam,
Thanks for your comment and recommendation.
I just recently made some "big" lens purchases and cannot afford the 24-70 in the $1000+ range. I have not priced it on the used market, but I imagine that it is demanding around $1000.
I may be able to get the local used 28-70 for $400 or so (asking is $450)
I use a K3 and not a K1 yet, so I imagine per your original comment that the 28-70 would be a good performer on the K-3.
I could test it out before I buy it. I have never done that. In fact, I would not even know how to do that properly.
I am not well versed in CA, aberrations, corner sharpness, etc.
Does anyone have a good resource or checklist on the best way to test a lens - especially for a first timer?
Best,
