  • Only DPRites could take a trite and discussed to death argument and extend it past 150 posts. In my opinion anyone resurrecting a dead 150 count thread s/b banned, no matter what side of the ...
  • Replied in plasticizers
    New plastic gives out a chemical that can deposit on any nearby surface. If you use a protectant like Armorall it can make it much worse. Do you have the lens inside a vinyl or plastic bag? Any ...
  • Replied in never
    No such thing as real world comparisons (maybe real world usage, but that's another story). I would never compare cameras w/images shot at different times. My camera goes from great to bad ...
  • Replied in well
    Don't know when you are going, it can be crowded at all time, especially in late December w/the mainland Chinese tourists. The most popular spot has a standard iron railing, right outside the ...
  • Raw is about post processing, touching up, and manipulating image intensity w/o losing quality. Yes, in a studio environment you probably don't need raw, because you control the lighting. You ...
  • Answer the magic question. Would you pay $1000 for cell phone lens that is 25MM F1.4? Would you brag about how hard it is to make a lens that will fit on your fingernail? Do you think it would ...
  • Commented on photo Apple'n'lemon in the fruit challenge

    Simple. Clever. Deep.

    I like it!

  • Replied in dumb
    It's ancient axiom. "Given enough light, all sensors perform about the same." Managing to blather about this for the billionth time doesn't make one brilliant. Yes Dorthy, if you want to take tiny ...
  • You want 3D printing to see if it would fit in your purse? And maybe 10 people would use that at what cost?
  • At fifty I was doing 120 miles of mountain biking a week. At sixty I switched to trail running. Still haven't given up carrying a FF with 100-400MM lens for 10 hours at a time Maybe at 70 I'll give ...
  • Replied in but
    Sure, you can make FF or even medium format mirrorless. But the op said mirrorless was smaller, not larger! As others have posted, same sensor size, same lens, gives about the same body with (for ...
  • From the title I thought this might be a dumb question, but it's actually pretty good. To paraphrase: in a $5000 plus pro camera, where the cost doesn't seem to be much of an issue, why aren't all ...
  • Isn't the title of this review a lie? There is no "hands on," no photos, no nothing except text from the vendor's press release. How does that add value?

  • Shame on DPR. The FAA or anyone else calls it a drone. There are no exceptions for distance or power. That's an unsubstantiaded quote from the manufacturer.

    Meaning, you can't fly it over people,...

  • Telescopes keep the same mirror size, lost the size. Impressive. Mirrorless cut the sensor in half, cut the optics in half, lost weight with a loss in performance while raising cost. No so impressive.
  • Replied in yup
    Some people object to a simplification on a beginners forum because it doesn't have the latest references to quantum theory. I call that the big fish in the little pond syndrome. Easy to look ...
  • Replied in oh my gosh
    The approach of the true believer. Use enough mumbo jumbo, add in some graphs, and you've won! Duh. All this to show glass isn't perfect, a conclusion hundreds of years old. Do the same analysis ...
  • To be effective, it would have to determine the subject from the background, start tracking, determine the movement of different body parts (hands, feet, head--or wheels, frame, wings, whatever), ...
  • No drone under the FAA weight limit needs to be registered. There is nothing special about a short range or limited flying time. Even if they don't have to be registered, they still have to met the...

  • Replied in not for me
    And for exactly the reason you posted. I don't need to pack a handful to cords in my suitcase, don't need to untangle them each time. Instead, try a wall plug converter for the country visited, and ...
