A) look sharp to my eyes. B) sends me to the login page I have been looking at various shots from our recent trip. All 10,000 shot with 18-250 Tamron or Sigma. There are some that aren't sharp but the ones that are good, i.e. subject and composition, are sharp enough for me. I don't have a prime to compare with (except an old M42 mount), I might try to borrow one soon to see the difference myself.

Quote Rob: "I find that my recently purchased zooms are in many respects almost as good as my Pentax primes when compared side by side in controlled situations, not like the bad old days". I concur with Rob. I have not bought a single prime, apart from the older collection of M42, M, K & A lenses. I have quite a few new zoom lenses - Pentax, Tamron and Sigma - some in the high quality f2.8 version. I have the Pentax 18-135 WR, and as I mentioned earlier it is a very sharp copy, with great contrast and colors. Quiet and excellent auto focusing too. And any zoom will show some sharpness drop off at the extreme ends. But alas!, I wanted some detractors amongst us PDMLers, to comment on two photos I posted on sharpness. Both blown up by 100%. Used primitive screen shot to capture the image. Link given below again for sharpness comment:- https://www.dropbox.com/sh/y2u0e14w64tl8u1/iWyqtCPDeS https://www.dropbox.com/home/Public/18-135%20WR Note: a) 100% crops. Some sharpness again lost due to my primitive screen capture method on my (5) year laptop. b) K-5 + 18-135 combo bought new from Henrys of Toronto shipped for CAD 1108 in January 2013 - CAD & USD at par then. I will be doing bench tests on edge to edge sharpness for the 18-135 using my famous beer bottle setup which I posted earlier for the Tamron 28-75 f2.8 Lens - $ 457 from B&H brand new - which turned out brutally sharp.
