  • K5 was proper competitor killer tool when it was introduced. That hi-iso performance was top in 2010. And still is very capable camera today. But now I had to select K3 as there was no better APS-C ...
  • That is completely off. There is ZERO need to replace any chip in DG/DC line of lenses to do upgrades so you don't need dock. Dock is only for latest ART lenses. HSM lenses like 50-150 HSM or ...
  • That depends on YOUR local options :) We have Sigma authorised service in capital city and you can either send it there or bring it there. Whatever fits you better. It will be similar in your country.
  • Since Kx was introduced with live-view AF, Sigma HSM lenses needed new firmware to work correctly. All you need is to take the lens to service and ask them to load latest FW to it. Then it works. D ...
  • Replied in Pointer...
    Point is that in usable range 100-3200 it makes no difference if you use K3, K3II, K70 or KP. The noise pattern is basically same just slightly affected by different PRIME +DNR in RAW.  And RAW ...
  • Pentax has even smaller slice and lives... sort of :D

  • K3 is good, he should rather learn to develop K3 photos better, there is no AA filter and resolution is higher, so any lens defect is even more visible :) KP only has better very high ISO shots, ...
  • 2000mm but that needs at least 1/1000s and that is not easy with F6.3
    ISO goes up quickly and details are gone anyway.. you need sunny day and bright subject. Not much use for general wildlife...

  • But still good to capture some fat politician with teen girls on yacht :D

  • Another paparazzi tool.

    But I'd rather have camera with 24-500/2.8-4 and 12mpix 1/1.6" BSI CMOS

  • Here these are more like $350-400 + heavily used lens will probably loose the contacts again soon. Those are just thin metal strips. Just L shape with just one end fixed. Sigma lenses have better ...
  • Earliest in 2022-23  if any.. and that only can be some minor K1 redesign implementing some modules from upcoming K-new APS-C. Certainly nothing radical as there are no R&D resources to do that. FF ...
  • It needs complete redesign. It was good lens in K100D times, but those are gone. With 6 aperture blades the bokeh is nothing special. Add some CA and purple fringing. The only advantage it has is ...
  • Created discussion thread DA18-135WR contacts
    Not a lucky day.. wonder how much this will cost. After 10 years.
  • I've fixed this with Sigma 18-35/1.8, Sigma 17-50/2.8, FA*24/2, FA35/2, DA40/2.8, FA50/1.4, and DA70/2.4 :)
  • Yes the central part of DA*300/4 is good, borders are below what DFA150-450 can provide in terms of detail. DA*300/4 has its age. It was developed in times when 10mpix APS-C was king. Better lens.. ...
  • On K20D I loved the FA*24/2 with K5 I rather use Sigma 17-50/2.8 and with K3 I prefer Sigma 18-35/1.8. But FA*24/2 stays in collection. It simply needs specific resolution and then it shines. K1 ...
  • TCs work best with lenses with high resolution and small circle of confusion design. DA*300/4 is not the greatest option. At least K1 has low resolution demand having about same pixel density as ...
  • There is no room for K1 on the market, yet for another camera. If you want cheap FF, just buy D750 which is now cheaper than KP and be happy..  there are tons of cheap F2.8 and F1.8 primes for it. ...
  • I've cut that with laser years ago.. but you can easily create similar ring with any thin conductive metal foil with sharp cutter.. or even a small piece of aluminium foil covering contacts is ...
