I would think one of the 70-200 F2.8's is what yoou would want to get.

the DA300 replaces the long end of the 100-300 you sold, and a 70-200F2.8 gets you the middle range again plus an advantage of 1 stop over what you sold.

At the other end, if you are not into ultra wide, the 16-50 should do everything you want, but I personally would never selel the sigma 10-20, but then again, that's just me.
You're making me feel sorry for having sold those lenses!
Oh well, as long as the buyers are happy, so am I.
True enough that I gain 1 stop which would be quite handy in a lot of situations, and that it would cover the missing link.
Thanks for the reply.

My first thought before seeing all the responses was the Tamron 70-200 with Tamron 1.4x TC, which gives you range between 70 and 280mm. Very fast, good IQ and cost-effective.

If you don't need all the FLs - just a few selecteds, then perhaps a set of 100, 200 and 300 primes would be nice - depends on your budget.
Why didn't I think about that? Good point as a matter of fact!
A 200 prime would be just about right, albeit on the long side a bit. The beautiful DA*200 F2.8 seems like a candidate but ... price-wise ... Ughhhh!
The more I read, the more I tend to lean toward the Tamron.
I'll have to search for some good reviews: I wonder (I will find out) if Photozone would have reviewed it?

I'm in agreement with Ash.... Tamron 70-200mm and TC
You seem to have a Tamron 70-200 Macro... is this the F2.8 version which we are talking about here?

Consideration under review! I will be looking into that one as well.
Is this a manual focus?
These are AF lenses, and bot the Pentax-F and FA series are optically identical. IQ wise I rate it only a notch below the limiteds and a tad better than the sigma 100-300.

It should be smaller than the 80-200's, and would be easier to put in a bag along with your 300. You do lose 135 to 300. but as I have my 100-300, it works better.

Yes it is. My review of the lens is posted here:

Oh Boy!
I just came back from the store and tested, i.e.: TOOK 4 pics this way:

1. K20D at 1600 ISO
2. K20D at 2000 ISO
3. K7 at 1600 ISO
4. K7 at 2000 ISO
Using a DA*16-50 f2.8 at 50mm; inside the store; BUT I made a mistake and forgot to take the K7 pictures in RAW, which I did with the K20D.
They were taken on a tripod to avoid blurr and because of the low shutter speed, even at 2000 ISO ... that could have an impact on the degree of noise, right?

So ... how do I post those photos here in the thread? Is it really worth doing this since one camera was used in RAW (K20D) and the other (K7) in JPEG? Should I go back and repeat the entire procedure?

Thus far, I can see quite a difference in noise between both cameras, when the photos are seen at 100% enlarged. Definitely more noise with the K7.

Maybe this should be moved to "DSLR Discussions" ... I was to quick to post this.

It's been such a long time since I posted photos here that I couldn't remember how to do it.
Thanks for the reminder ... I hope my Photobucket account (which I had completely forgotten about) is still valid.

Such an ugly PF... it must be a horrible lens!

Joking aside from the 70-200 candidates that you suggested I am leaning to the Tammy as well. That or the 50-135... The 70-200 will suit me better but I heard so much rave reviews on the 50-130. I think I'll grab whiever good deal comes at me first.

No kidding!
Brain-freeze seems to be "in" theses days ... at least for me.
So, I haven't had the chance to load the pics to PBucket yet, but will soon.

I know both lenses have great reviews now.
I am undecided between both, but leaning toward the Tamron 70-200 f2.8 because of its larger "latitude"
