Originally posted by Jool I bought the Pentax DA*50-135 about a year ago and really like it. I'm using my Tokina 28-70 2.8 that I bought a long time ago before I switched to digital (K-5). 28 really isn't wide enough and it will not focus at that focal length. Tokina may be able to calibrate it to work but I want something different anyways. I was waiting for Pentax to come out with a new DA* short zoom but it doesn't look like it will be anytime soon. I debated getting the current DA*16-50 but would rather see what they come out with to replace that one. In the mean time I'm looking at the Sigma 17-50 2.8 because it is a lot cheaper than the Pentax and I could use the Sigma until the new Pentax came out. I don't know if that would be wise to do or not. My choices are to just keep using what I have, buy the Pentax DA*16-50, or buy the Sigma 17-50 and then get the new Pentax zoom when Ricoh releases it. What would you do given these choices? Thanks in advance for any input and advice you may have.
I'm on the same situation,I Also have the 50-135, the 12-24, and waiting for something on that range, preferable 17-70mm, There is a new Sigma 17-70 f/2.8-4 DC Macro HSM for Pentax, I would love to see some reviews here
