  • Hi John, I answered the separate thread you started on this subject. The long and short is that you are misinterpreting the manual I think. A very similar description is in the SX50 manual with the ...
  • Hi John, I read this page differently. My reading is that you choose the Auto ISO icon to get to the selections. The selections are Auto or individual ISO values across the whole range available. I ...
  • Hi Joaquin, You didn't show us the photos before you stitched them--that would probably give us some clues. In my experience, dating back to 2002 with my Canon S45, I've not known the Stitching ...
  • Hi Augustin, For reasonably well exposed, low ISO images DPP is great and definitely easy. RT is surprisingly easy when you realize that you get to choose one out of several tools to each ...
  • Your opinion is clear. My opinion differs from yours. Continuous shooting directly to memory at 6.4 frames per second until the memory is filled looks like a total game changer to me. Doing that ...
  • Google "cheat sheet SX50" and you'll find something. I have no idea of its utility. Sharpness and contrast can be adjusted under "Custom Colors" (page 125-126 in my copy of the manual). Exposure ...
  • To me it seemed that you have already put in significant effort. Installing RawTherapee is simple in Linux and probably not too painful in other OSes. The selection of one algorithm over another ...
  • Stephen, I thought I was fussy. Thanks for showing me that I'm a wimp. ;) I'm betting on demosaicing and subsequent sharpening to be major artifactual (camera/processing) causes. To eliminate the ...
  • Of course it is not the same sensor that has been bumped, simply the same size of sensor using almost certainly better technology to complement the faster processing of the Digic 6--enabling ...
  • Actually the aperture must change to keep minimum f-stop at f 6.5 for a range of focal lengths and then f 5.6 for a range of focal lengths and so on as the FL decreases. But yes, I should have ...
  • Stephen, You're welcome. I'm not totally sold yet. Canon has only very rarely introduced a lemon of a P&S and this one is their flagship model so I am betting that the extra year's wait was all ...
  • Or it would mean less telephoto at maximum zoom ala the FZ1000 and would then it would not be as super a superzoom and more folks would be disappointed. Those who want a larger sensor should ...
  • What do you think the minimum distance is for the SX60 at 1200 mm equivalent? I'm betting it isn't worse than the SX50. I find pseudo-macro to work best for me at modest FLs and closer distances ...
  • If you sold two years ago then you sold almost immediately after buying since it wasn't announced by Canon at Photokina in September 2012. I couldn't find one to look at until October 2012. Time ...
  • So from Canon we have their evaluation of what they've offered us: We'll be the judge of optical performance. No spec yet on what FL the aperture gets wider. It's not easy to evaluate that claim of ...
  • With almost no news at all that counts (resolution, ISO vs noise performance, shooting speed--burst speed--and stash to memory performance, AF performance, EVF quality) it is impossible for me to ...
  • That's assuming that the sensors have identical aspect ratios being used for the calculation and that they are using the same assumptions. The actual "equivalent" focal lengths are often rather ...
  • Nice one Ed! As folks who view my posts know, I am particularly fond of raptors and of storm light and this fulfills both beautifully. Regards, Don
  • Very nice Evan, Keep up the raw experimentation and you'll get that small amount of residual noise under control and perhaps a little more dynamic range out of the images taken at low light. As ...
  • Augustin and Evan, Thanks for your comments. I thought that the image was extreme enough to make the point and I think I might have failed there. In reality, I don't usually work over images that ...
