  • with the SD Q which is supposed to be 1 stop better than DPQ according to SIgma's boss ? How does it compare to DPQ ? Unless this noise problem is fixed,  IMO the SDQ could be the last Sigma camera rd
  • It looks to me that to get the max from a Merrill, you got to use a tripod and a remote trigger or delayed trigger and to see at 6 inches all what you get , to print at much more than 16x20 (which ...
  • on the car engine pic - the 2 cylinder one - I still see blotches on the engine - at least on "High rez" jpg also on the last pic - the bicycle wheel IMO this should not be there at least at ISO 100 ...
  • you mean the 1 stop thing ? see I really dont know... Those blotches remind me of my Sd14 (but not at ISO 100 !)
  • I see color blotches in most pictures even  the new SDQ is supposed to be 1 stop better than previous DP Quattro generation at ISO 100 eg on upper leaves - the yellowish part ...
  • this could also depend on the printer and paper used - is the printer the same for large and small prints? as far as I know among basic questions are - calibration of your monitor - color profiles ...
  • - hope that those pans will be ok ! - the picture is "as is"... not cropped - I dont print often (and not very large size) - as for the noise, it's probably because of underexposure  - I dont ...

  • Created discussion thread Autofocus test of my 18-200 on SD1
    Had some doubts about the autofocus of my 18-200mm C - my walk around lens so I did a test with this packaging cardboard and was surprised setup: lens at 200mm, autofocus, OS off, exposure -1, all ...

  • KY: It has the same pixel size, so it is the same. But for the sd Quattro we changed some algorithms in the image processing, so we could improve the high ISO performance, by ...
  • Replied in the simple way
    I think that the simple way is - create a work directory with a simple name, e.g."1" or "a" - since cmd.exe opens by default in C:\Users\"a name", you can create this new directory.. - or at the ...
  • if you look her legs - where shadows are the heaviest (and its is not that much) you will probably see,  like me,  lots of noise at ISO 640, which is not so high for a FF with Sony's latest tech ht ...
  • Yes, lots of noise, green everywhere on the skin of her neck on my 30" Dell screen and this one, also ISO800 - looks like green blotches on the gutter (in the shadow) ...
  • I must confess that I'm also tempted to switch to A7RII so, I'm regularly looking at pics on Sony FF forum this is an example of ISO 800 - raw developped with DXO - look at it at 100% when I see ...
  • I dont mind with those critics... very good (to say the least) IMO as is your gallery rd
  • divide ISO by  2= 1 stop add  1 F stop  (5.6 to 8... no more than F11... or according to DXOMARK best setting) = 1 stop multiply speed by 2 = 1 stop = best quality really dont undestand the need of ...
  • remember that depth of field at 300mm/F8 for APSC at 40 feet is about 2 feet it can only do what it can do rd
