    I'm a retired scientist. My area of research was dependent on analog and digital electronics and for years it required me to create a variety of analog and digital instruments. I understand ...
  • over and  out
  • No, not curt. Something else. You also said, "I am just very careful before believing postings of random strangers on the internet." Not quick and curt, carefully brief and snarky? Maybe you need ...
  • You're so careful that you used similar snark in a previous thread when you essentially called me a liar. (Twice I think saying that you didn't believe me.) I'm still "random" to you? You're an ...
  • Lol, poor boy, I knew that you would need links. That's because I expected you to not take my word for it since you likely believed it when you said "no one here knows." I have a PhD in Physiology ...
  • Not exactly true. Also not quite true (as long as you stay away from the metaphysical). There are two major styles of eye movement: saccades and smooth pursuit. Saccades are rapid movements from ...
  • Wow! You didn't care how long that tedious, rambling bullpucky went on and on and on and.... (BTW, counting the paragraphs in that drivel was far faster than reading the whole tedious screed.)
  • Yeah, I spent a huge amount of energy to stop reading at 4 paragraphs (out of 15) and to declare in a single sentence that it was an exercise in irrelevant pompous bombast. Gee, I was gasping at ...
  • When it is so tediously long that it becomes irrelevant after the first 4 paragraphs out of 15, becoming a totally boring display of wordiness.
  • He didn't say "all moving objects." The context was a series of posts explaining the issue with far more nuance and far more rational thought than you seem capable of. Isolating that sentence from ...
  • The one I bought had several issues including too much weight compared to the superzoom itself. The whole point is what the camera by itself can do--not what you can add to it to make up for its ...
  • Peregrine falcon assuming several distinct "speed forms" all of which allow it to go very, very fast. The first level: wings cupped near the body, wing-tips out. Faster than most fast birds its ...
  • I haven't seen the 'difficult bird specialists in the m4/3 forum.' Point out some threads because I am curious and open minded. I'm not trying to prove anything. Donald B. wanted a photo of what ...
  • Kiwi said, "It was Lee Jay claiming mirrorless cameras can't take photos of moving objects because of EVF lag. That was actually a lie. Lee Jay made no such claim about all moving objects. You ...
  • My main (by far) wildlife subjects are peregrine falcons, the fastest creatures on earth . I don't have any faith in your ability to understand from an image how fast and unpredictable their flight ...
  • Wrong, at least for the red dot sight I bought and returned. It had far wider field of view (far less magnification) than the EVF superzoom I was trying to use it with. Also far less magnification ...
  • Red Tails are easy, slow and predictable compared to the birds I shoot. I am glad he finds that combination useful. I tried a red dot finder with my SX50 and found it not useful with full zoom out ...
  • Pick on mirrorless? Oh, come on fella. Stop whining. The "workarounds" are nothing of the sort. You cannot work around the lag that makes framing more difficult. All the pre-burst stuff is useful ...
  • No, not a "whipping boy." A fact of EVF life that presents a special problem for some kinds of subjects. It's really simple and you and others try to conflate it with a variety of other attributes ...
  • No, I don't think they do cover the issue of fast moving or unpredictable. Gliding birds I've already commented on. They're easy. A taking off prop airplane is predictable, slow and easy to pan. ...
