  1. It's a desperate attempt by Nikon to catch up to Sony. But, they have a long way to go. I love my A7RIII. John
  2. I've completely gone over to Sony after using Nikon since the 70s. I have the A7RIII. It is an incredible camera. John
  3. Sure I considered it. But, I don't have the energy any longer to climb. I'm still dealing with the after affects of Lyme disease. John
  4. I was hanging from a cliff to get this shot and holding the camera as low as possible to see through the bushes. There was only a small opening in the bushes. No processing done. John
  5. Makamah Nature Preserve - Northport, NY. October 31, 2018 Sony A7RIII, Sony 28-70 mm lens at 28 mm.
  6. Sony A7RIII, Sigma 100-400 mm lens with MC-11 adapter at 400mm
  7. I'm a convert from Nikon so I'm not used to the Sony A7RIII. My thumb keeps accidentally touching the exposure compensation dial and messing up my exposure. Is there a way to disable the exposure compensation dial? John
  8. There are more focal lengths shown on this post: John
  9. This posting belongs to the lens forum and the wildlife forum. I posted it on the lens forum. It may be helpful when selecting a lens for bird photography. John

  11. 1971. Nikon F. 35 mm camera. Kodak Kodacolor 125 Film. Montauk, NY I don't remember the settings. It was scanned from a 3.5 x 5 print at 180 dpi about 30 years ago. John

  13. This was taken with the A7RIII and the 70-300 mm lens. Distance: 40 feet, handheld Focal Length: 300 mm Aperture: f/8 Shutter Speed: 1/320 ISO: 1600
  14. It was finally sunny at my home in Northport after many days of rain and clouds. I traveled to a lake to photograph it with my new 16-35 mm FE lens at 16 mm. When I got there, it was cloudy. I took the shot anyway. (Sony A7RIII, 16-35 mm FE lens at 16 mm, f/8, 1/640 sec, ISO 100) John
