DA 50 - 135 or tamaron 70 - 200

I'm having this dificult choice to make,
It's between this two amazing lens
right this are my reasons to consider
it's gonna be used for portraits

tamaron has longer range(although 70 is a bit to much I already have a
sigma 17 - 70 to complet the set if a need to do a full body)
and is more solid built.

DA has a better range and is lighter

so I don't know what to get.
bear in mind that both lensses are farly expensive for my pocket
so it will have to be a definitive choice.

Oops. I'd go with the tamron, the extra range may come in handy, and I think it compliments the 17-70 much better

I own them both and like it that way. They are similar but different in use IMHO. This question has come up a number of times on this forum be sure to search out other discussions on this. In my opinion, the image quality is nearly the same. Clearly the Tammy's bigger than the Pentax. With both lenses I always want more length and conversely I'd like a bit more width. One thing about the Tammy is that you can use it on newer film cameras if that's a factor.

I'd tend to use the Tammy for all purpose sports stuff and the Pentax for indoor things and portraits. Given that you said portraits, I'd go with the Pentax. $0.02USD

For portraits, if you are sure you want zoom, get the DA*. But still the bokeh is not as good as with primes.

For Portraits the DA* 50-135 would be better suited , the 50-70 range would be more useful than the 135-200 range of the Tamron.

Also the Sigma 50-150 f/2.8 HSM is also one to consider, excellent IQ, fast and silent AF, plus has a bit range than the DA* 50-135.

50-135 for IQ
70-200 for reach

or 50-135 + Tamron 1.4x for almost both of the above (you will lose 1 stop though)

Highly recommended. HSM is so fast it pulls focus before the SR is ready. Sigma also backs up this lens with a 10 year warranty whereas Pentax only backs up the 50-135 with a 2 year warranty (here in Canada).

50-135 is great for portraits.

Sigma 50-150 as far as I know has been discontinued...

There is a new OS version, but it would have been nice if they kept the non OS version available for Pentax. I was lucky to pick one up just recently and compared to the 50-135, I made the right decision.

70-200. Personally I found it to be even sharper than 50-135 at wide open, especially at longer end. However 70-200mm is a bit heavy.

This may sound like a good recommendation, but I've actually tried this and you will be sorely disappointed. AF hunts like crazy, almost impossible to lock on. (Tamron 1.4 TC does, however, work well with my DA* 300/4 - go figure!)

I agree with Blackcloudbrew 100%. However when I require a long zoom, nine times out of ten I grab the DA*50-135. Personally I think it has a slight edge in IQ, but just barely. The sheer size of the Tamron is usually what deters me from using it.

this is also my question in my mind.
135-200mm difference is huge, but 70-200 is a huge lens also.
i'd like to have a quality but carriable tele.
This opposites with tamron unfortunatelly.
I think i would go for 60-250, if it is not so much pricey.

Put your telezoom on the camera and try the 135-200 differnece for yourself. Not huge at all.

Agree. Shooting portraits at much longer than 135mm is not something I ever do. There are places where a little extra reach would be useful and certainly, the focus is pretty slow on the 50-135, but if primary purpose is portrait shooting, I would go with the DA * lens.
