Leonard Migliore's recent activity

  • As has been noted, my age group was not included. Perhaps you are under the impression that people over the age of 55 are too feeble to buy anything or too demented to fill out surveys or too ...
  • Replied in Undersize mount
    The register distance doesn't affect the image circle. It's going to be 43mm for full frame regardless of what's going on in front of it. I mean, light's not supposed to hit the lens mount at all ...
  • Replied in x30
    Absolutely. I should have noted that trying to match focal lengths with a compact camera is not a good direction; soufiej's post covers that quite well.
  • No, de East River.
  • Replied in Focus location
    It's the worst rule in town. What about hyperfocal distance? The "in focus" range goes from half the focus distance to infinity. Now there's someplace where you have twice as much distance in back ...
  • Replied in x30
    It's somewhat circuitous. On fixed-lens cameras, "X" refers to the ratio of the longest focal length to the shortest focal length. So an X30 camera has a telephoto focal length 30 times that of its ...
  • Well, I dropped a lens cap into the East River while I was climbing on the Queensboro Bridge. No way I go into the East River to get a lens cap. No way I would go even if it was the camera.
  • I am using principal planes precisely because I'm discussing something other than a thin lens. For real lenses, object distances are referenced to the first principal plane while image distance is ...
  • My RX100, which is the camera I'd most likely be using if I wanted to send something immediately, will send a JPG to my phone even when I'm shooting RAW. So I don't even need to shoot JPG's for that.
  • Shoot RAW only and get Lightroom. With Lightroom, you don't need the JPG's. Lightroom will make you one whenever you want it. So just shoot RAW and import into Lightroom; all your problems will be ...
  • Well, what you want to do to maintain the angle of view is to keep the distance from the second principal plane to the sensor constant. At infinity, a 200mm lens has a distance of 200mm from the ...
  • I was afraid to click on your post because I figured it would take really long to open.
  • That makes sense. My G12 isn't all that compact with the filter holder attached.
  • Replied in Lens vs. lenses
    First, I have to admit that I don't have any of the lenses you mention. They are, however, all supposed to be pretty good, at least as claimed on these forums. Given that all the lenses work OK, ...
  • You got a glue-on filter holder for a G15? Canon sells an adapter for 58mm filters that attaches to the camera body. That seems more secure to me.
  • It probably can't be used on a full frame sensor because it would not cover a full frame sensor; the lens is designed to cover the Fuji's crop sensor.
  • Replied in Cat skinning
    My cat is getting quite upset about all this talk of skinning. Please consider another metaphor.
  • Note that I provided a straightforward answer when you asked about the focal length loss of the Nikon 70/200 f/2.8 at close focus distances. I said "so don't get one" when you were complaining ...
  • The 16mm lens will cover the entire frame (this is called a "full-frame" fisheye but that's a different sense than you were using). It covers 180 degrees on the diagonal. The 12mm lens produces a ...
