  1. For the moon shot, I used manual focus. I more recently upgraded to the Sony 200-600 mm lens. John
  2. The snow is coming. We are experiencing a slightly warmer spell around 40 degrees F. right now. It gets down to zero in the winter. John
  3. A6600, 70-350 mm at 350 mm, handheld
  4. This is a controversial topic. Some people say filters degrade the image. john
  5. I used the B + W 72mm UV Protection Filter (010) for Camera Lens - Xtra Slim Mount (XS-PRO), MRC Nano, 16 Layers Multi-Resistant and Nano Coating, Photography Filter, 72 mm, Clear Protector with the A9 and 70-300 mm lens at 300 mm, f/8, and available ceiling LED lighting. See test below. It doesn't look like the filter affected the resolution. Perhaps the photo with the filter is slightly better. The photos were untouched. Only reduced file size for posting. The photo on the left was with the filter. The photo on the right was without the filter. John
  6. This newly discovered (by me) method of carrying makes a huge difference. http://www.drjohnphotography.com/papers/Carrying-Photographic-Equipment-The-Easy-Way.pdf John
  7. After testing out the A9 with the 24-240 lens, A9 with the 70-300 lens, and the A6600 with the 70-350 lens, I decided to keep the A6600 and lens. See attached comparison.
  8. This was taken with the A9 at f/8. File size reduced for this post. The photo was an uncompressed raw file, untouched. 70-300 on the left. 24-240 on the right. John
  9. Sometimes, I accidentally spin the exposure compensation dial on my A7C when I see wildlife and quickly remove my camera from the bag. There is an item in the menu to disable that dial. But, it doesn't work. I called Sony. They determined it was a firmware problem and will try to get it fixed for the next firmware update. I also suggested they make the dial lock like it does on my A7RIV on their upgrade of the A7C. John 5/19/21
  10. For serious work, I use my A7RIV. But, for everyday type of carry when I'm not even sure I will use it, I use the A7C. Adding a 24-105 mm lens to that camera makes it heavier than I would like. I dug up from my collection the Sony 28-70 mm kit lens to test. It is a very inexpensive lens. I didn't expect much from it. But, I was surprised. Attached you will see an unedited photo with reduced file size for the web. John

  13. I have lots of longer lenses. But, didn't expect this bird and didn't have time to change lenses. John
  14. I was in my backyard today with my 24-105 mm G lens on my A7C. A bird flew down and landed on my lawn. I didn't have time to change to a telephoto lens, so I took the shot at 105 mm and cropped the heck out of it. The cropped photo is still sharp and clear. The file size was reduced to fit here. John
  15. I found the combination of 70-300 and 24-105 on the A7C to be ideal for me. The next step is to get a case that will enable me to carry it easier. I found the Tenba Solstice 12L Backpack (2 pounds) works fine. John
  16. I've been spell bound by the full frame fairy. John
  17. I went out shooting yesterday carrying the 24-105 and the 70-300 mm. My shoulder still hurts. It was ok in the woods. When I went to the beach, I had the 24-105 mm lens on the camera. The flying seagulls came out too small at 105 mm. I didn't dare change lens at the beach because it is against the law - Murphy's law. I'm still thinking about the 24-240 mm lens. I normally shoot manual, 1/100 to 1/200 for landscape and 1/500 to 1/4000 for wildlife and flying birds. I shoot f/8 and auto iso. John
  18. Today, I put the 24-105 f/4 in my bag along with the 70-300. I will try that combination out. John
  19. I just purchased the Think Tank Urban Access Sling 10. It is the best case I have ever owned. It also comes with a waist belt. John
  20. I have the Sony 16-35 f/4, which is another option. John
