  1. Sony A7RIV, 200-600 mm at 600 mm, 2x teleconverter, 1/250 second, f13, ISO 800, manual focus, hazy sky
  2. There is already a section on Birds in Flight where people have submitted really fine photographs. I think it will be helpful to find out what camera was used, what lens was used, and the camera settings. So, please submit any information and tips and tricks here. John
  3. Were the shots handheld or tripod? John
  4. Sony A6500. Sony 70-350 mm at 156 mm. 1/2000th sec. ISO 320. f/8. He/she was moving rather quickly. John
  5. Has anyone use the Sony 200-600 mm lens for astrophotography? I'm considering it for lunar photography. I also have the 1.4x and 2.0x teleconverters and the Sony 100-400 mm lens. I also have telescopes, but feel one gets better resolution from camera lenses than reasonably prices amateur telescopes. John
  6. After being cooped up all winter with nasty weather and Covid 19 shutdown in New York, it felt really good to get out hiking and taking photos. This was my first photo of the season. I didn't expect to take any photos so I left the A7RIV home and just took the A6500. The swan was on the far side of the pond. Sony A6500, Sony 70-350 mm at 350 mm, 1/2000 sec, f/6.3, ISO 1250, handheld John
  7. A cold and dreary morning during Covid 19 lockdown in New York. All parks, beaches, trails, etc are closed in NY until at least May 15th. I believe it is a $1,000 fine if caught there. This was my backyard on a cold morning (35 degrees F). No flowers in bloom yet. Not much to photo in my backyard. John
  8. I'm thinking of setting shutter speed and aperture manually and trying out auto ISO. John
  9. I should have said "Waiting in the woods where deer and other animals hang out for many hours." John
  10. Thanks Chrissie for your information. I've been doing wildlife for a long time, but not birds in flight. I have spent many many hours waiting for a shot that never happened. I currently have the A7RIV and the Sony 100-400 mm with 1.4x and 2.0x teleconverters. I'm also considering the new Sony 200-600 mm. Both lenses and camera have OSS. I live near the water. So. Seagulls are easy to find. They even fly over my house. And, for some reason I really like seagulls. John
  11. I posted a photo I took sometime in the 1970s of a seagull in flight under the "Birds in Flight" Topic. Following this topic has inspired me. You are all doing such great work. This spring I want to to photograph birds in flight again. I cannot remember the camera settings I used 50+ years ago. Off the top of my head I'm thinking of using a shutter speed of 1/1000 sec and maybe f/6.3 and maybe auto ISO. Please list some settings you have had good results with. John
  12. I was out last night with my A6500 camera and 70-350 mm lens. The focal length was too short for lunar photography. It was what I had on hand and so I took the shot anyway. You can enlarge this photo 200-300% without it degrading too much. I reduced size for the internet. The Sony cameras and lenses are really great. John
  13. The reviews on the Sigma 14-24 f/2.8 Art Lens were excellent. So, I ordered it for $1399. I will use the Sony 16-35 f/4 for travel because it is lighter in weight. John
  14. I have the Sony 16-35 mm f/4 lens that I use for landscape photography. The rule of thumb for astrophotography is f/2.8 or faster. I can't test the 16-35 mm from home because there is almost always clouds or a mist blocking the stars. Has anyone tried it? I'm also considering the Sigma 14-24 mm f/2.8 lens. I have the Sony A7RIV camera. John
