  • I really appreciate everyone's comments and apologize for not getting back sooner.  For my purposes the 55-300 is good enough for a light weight walk around lens.  I have done several tripod ...
  • I am shooting single shot mode.  I push the button half way down, listen for the high pitched tone and red lines for a second in the viewfinder telling me I am in focus and then push the rest of ...
  • I was thinking the motion compensation being on would take care of the motion on the longer exposures.  But I am seeing the issue at speeds like 1/200 second.  The images definitely look out of ...
  • I am pretty sure it is a K3 iii issue, because the 2 screenshots I posted with the focus issue are from two different lenses.  one is the 70-210 mm, but the second is for my 150-450mm set at 200 mm.
  • I always update to the latest K3 iii firmware and have been using Rev 1.50 since a day or two after its release. I have been shooting AF-S except for occasional experiments with AF-C.  I shoot ...
  • Replied in Really?
    I received my 70-210mm from B&H and have started comparing it with my 55-300mm PLM. I started a new thread here: https://www.dpreview.com/forums/post/66391046 It is not worth keeping the 70-210 if ...
  • I just received a Pentax 70-210 mm zoom and am comparing it against two other lenses that cover that zoom range (150-450mm and 55-300mm PLM). My initial shots comparing against the 55-300 mm showed ...
  • Created discussion thread Focus Oscillation in K3 iii?
    I just received a Pentax 70-210 mm zoom and am comparing it against two other lenses that cover that zoom range (150-450mm and 55-300mm PLM).  My initial shots comparing against the 55-300 mm ...
  • Michael, I just tried the TAv walking around before dinner tonight.  Very interesting mode I was not aware of.  Thanks for pointing it out.  I very frequently use M and separately set the ISO.  The ...
  • Replied in Hot Tips
    Michael and Doug, Hey thank you very much for taking time do demo shots.   Your comments and photos are very helpful and I do plan to order the 70-210 tonight. Do you guys use it on a tripod with ...
  • Created discussion thread Thoughts on Pentax DFA 70-210?
    I see the Pentax DFA 70-210 is being discounted right now.   I shoot APS-C only.   I have read some reviews and see it is very well rated for image sharpness.  Currently I use the 55-300 mm PLM, ...
  • Replied in Look better!
    Roland, That's exactly what I do.  It goes in my shoulder bag when not in use. I purchased it for my K-70 a long time ago.  So I was used to using it when I got the K3 iii.
  • Replied in Look better!
    It uses a single AAA battery which weighs 11 grams and as I said it last several weeks for me.  "Large" is relative I guess.  I find it small compared with lenses and very easy to have on the ...
  • Replied in Look better!
    Roland, I like gps too and use the O-GPS1 on my k3 iii daily.  It is accurate and I find it convenient.  I do carry a spare AAA battery, but changes are quite infrequent.  Maybe every few weeks.
  • I don't belong to any private Facebook groups either and agree it should be made public if it's going to have information of general interest.
  • Are you referring to this article published in dpreview about 4 months ago? https://www.dpreview.com/news/5938566942/japan-sends-a-modified-pentax-300mm-f4-lens-into-space-aboard-its-kitsune-6-micr ...
  • You need to follow that link to the English translation at Pentax rumors: https://pentaxrumors.com/2022/07/06/interview-with-ricoh-imaging-president-noboru-akahane/
  • I am going to partially answer my own questions. I should have checked Ricoh's site first. See: https://www.ricoh-imaging.co.jp/english/products/o-gps2/calibration/ Where it says: "Calibration data ...
  • I own and use the O-GPS1 and use it daily for the GPS.  I have used it occasionally for sky photography and found it to be erratic.  Sometimes it works perfectly and sometimes there are star ...
  • Thanks for letting me know.  I have a new 3 amp charger for my phone, so now I will feel comfortable using on my K3-iii.  This indeed is a handy feature of the camera.
