  • I am using Canon's Image Stabilizer binoculars for many years. They use similar technology (variable prism) and work great.

  • This is exactly what I meant - the reviewers should agree on some final output size (sufficiently large) - I called it a "print size" - and compare results at this size and not at meaningless ...
  • The new iMac with retina display, in addition to quite a few laptops with retina-like screens on the market show that soon displays with pixels smaller than comfortable resolving power of human ...
  • That was exactly my point. Any solvent stronger than IPA will damage plastic components of the lens (housing, internal parts, etc.). Acetone will ruin a lens for sure...
  • It takes a lot of Windex to clean a 2005 thread so it looks like new again ;) On a more serious note, long ago I was working with high-power lasers. If optical components of the open-air system had ...
  • I'd like to thank everybody who replied to this thread. I think I will start shooting SF JPG + RAW to see what I can pull out of RAWs.
  • I am using E-M1 and, comparing to my Canon DSLR (now sold), JPGs are so good, that I am not sure if shooting RAW will result in improvement worth the efforts. I am aware that JPGs are limited to 8 ...
  • You can achieve the same DOF on FF by stopping the lens. If you are using f/11 on 4/3, stop the FF lens to f/22. Diffraction disk will be bigger, but so are the FF pixels. The only advantage of ...

    After 35 overwrites with random data?
  • Replied in CCleaner
    Download free CCleaner. First, delete the images to the Recycle bin. In Cleaner menu, scroll down to Advanced , and check Wipe Free Space option. Next, go to Options / Settings , choose Secure Deletion
  • I am, personally, somewhat tired of endless discussions of equivalency and related issues. Here is a simple explanation of what is really going on, and once I realized that, I do not try to analyze ...
  • Replied in Myth number Zero
    Myth number Zero: You cannot be considered a serious photographer if you do not shoot with Full frame :)
  • An interesting additional benefit of polarized sunglasses - I developed a habit of tilting my head to my left shoulder, and then - to my right shoulder. I observe how the sky and reflections from ...
  • You did the right thing - and in the future, if any portable electronic device is exposed to water, remove the battery ASAP! This will prevent electro-chemical corrosion. Then, dry it quickly on ...
  • Created discussions Antigravity
    E-M1 & 12-40mm Digging for Unobtanium:
  • A few more... Some minimal post-processing (crop, resize, levels). Thanks for looking!
  • I bought 75-300mm to take it on the upcoming Alaska cruise, and I was not sure how usable it would be between 250 - 300mm handheld. I had a chance to use it yesterday in the nearby lake park. All ...
  • Replied in Also...
    At such a wide angle each mm of focal length makes a noticeable difference in viewing angle and perspective. So a single, say, 9mm prime will not substitute a 7-14mm zoom. Additionally, optical ...
  • I am planning to use the monopod on the shore. My monopod is very light (330 g, .71 lb), but I am not sure if I will have time during the short excursion bus stops to use the monopod. Thanks for ...
  • Created discussions Monopod question
    My wife and I are taking a cruise to Alaska soon. My camera is Olympus E-M1 with a few lenses, including telephoto (75-300mm). I have a small and light monopod (Gitzo GM2561T). Will I need the ...
