<p>Thank you to those that gave informative comparisons and thoughtful replies. My apologies for taking so long to reply. A significant change in family circumstances recently has me with much less time than my already busy life had (I am now caring for my two year old daughter full time, plus working my day job).</p> <p>I ended up buying a Pentax 24-70 from the Australian Pentax webstore at a 10% discount (AUD$1800). Why? On paper it would seem to be the best full frame normal zoom available with a 2.8 aperture.</p> <p>Initial impressions are that although it is not a light weight, it feels perfectly at home on my K-3II with grip. It feels good in the hand with the zoom and focus rings well placed. It didn’t take much to get used to the zoom being out the front and now feels natural.</p> <p>I was not impressed with the sharpness of images initially, but I did some focus accuracy checks and found it was back focussing. This info:</p> <p> <p> about Dot Tuning was quite helpful. Using this Focus Pyramid:</p> <p><a href=" <p>seemed to confirm what I was seeing with dot tuning. I calibrated the lens to +5.</p> <p>I shot a wedding two weeks ago in a dimly lit chapel using ISO 1600 (mostly), f2.8 @ 1/60. Initial results seem quite good. I will post something when time permits.</p> <p>Thanks again,</p> <p>Dave</p>

<p>Adam, you raise some interesting points that had been in the background for me. <br> 1) You are correct about the Quick-Shift focussing - none on the 28-75 and yes on the new D FA24-70 2.8. This would probably be very handy especially covering weddings and events. Also having SDM - I've never had it before, which I guess would be much quicker, surer and quieter than the old screwdrive.<br> 2) You are probably right re in body corrections: http://www.ricoh-imaging.co.jp/english/products/k-1/feature/index.html<br> 3) Yes, new lens sealed, old not<br> 4) Will look into the comparison you offered.</p> <p>I'm also thinking that the new body would be more advanced &/or matched to newer bodies better with overall improved image quality.</p> <p>Thanks for your thoughts,<br> Dave</p> <dl><dd></dd><dt>Quick-Shift Focus system</dt></dl>

<p>I would like to hear from anyone who has had experiences with both lenses as to their pros and cons, especially if used on a K-1</p> <p>I shoot landscapes, macro, weddings, functions, families and other things.<br /> I’m currently using a K-3II as my main body. I’ve gotten by for a number of years with the best lenses I could afford at the time; Tamron 28-75 2.8, Sigma 70-200 2.8, Tamron 17-35 2.8-4. My 28-75 is around 10 years old and has served me well and has seen lots of use plus some knocks and drops. I sent it to be serviced but was advised that it had resolution and focus issues as well as a loose barrel (not surprised about these and confirm some suspicions) and would cost about $AUD300 and need to be sent to Japan (from Australia) taking around 4 weeks.</p> <p>I want to take my photography more seriously and earn more of my income from it so, my plans are to eventually upgrade to a K-1 (and possibly the Pentax 15-30mm 2.8 and DFA 70-200 2.8). Right now I need to decide about replacing my 28-75 with the same lens for around $AUD500 or go all out for the Pentax DFA 24-70 for $AUD2000. I’m not interested if it is a rebadged Tamron unless someone can confirm that it is totally Tamron – Maybe it is a Tamron barrel with Pentax glass? And even then, the real question is: is it better than the 28-75 in performance and handling and actual use?</p>
