Advice needed please

Morning all.
I wonder if I can trouble you for some advice.
At the moment I have both the DA* 50-135 and Sigma 50-150 HSM lenses. I have now decided to get the DA* 60-250 and so would like to get rid of one of the other 2 lenses.
My question to you is simple - If you were me, which one would you keep?
Oh BTW, would it be reasonable to ask what price would each fetch - both in excellent condition. Pentax is 1 year old while Sigma is 2 years.
Many thanks.

That's a daft question Naim, everyone's going to tell you to sell the lens they want to buy I don't need either, I've already got a DA*50-135, let me know when you tire of the 60-250

Simple answer is to ask yourself which of the two do/did you use the most, but I will hazard a guess that the majority of votes will tell you to keep the Pentax.

I would keep the 59-135mm purely for the wr

Keep the DA* 50-135 it's one of the best lenses Pentax make and is so versatile.

Thanks. You guys have just confirmed to me what my gut feeling was. The extra 15mm on the Sigma won't matter because of the other lens that I am acquiring. The slight down side is that Sigma will not fetch as much price as the 50-135.

I had to make the same choice (bought the 60-250mm) and kept the 50-150mm. IQ is ever so slightly better on the Pentax but the faster autofocus of the Sigma swung it for me.

I'd keep the DA* 50-135. I love mine. Its' the most boring focal length Zoom I have but it's perfect at those focal lengths. Stunning quality

You don't by any chance work for Pentax UK marketing do you Smeggy?
