  1. Sony A9, 70-300 mm lens at 70 mm.
  2. A6600, 70-350 mm at 350 mm, handheld
  3. This is a controversial topic. Some people say filters degrade the image. john
  4. 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
  5. 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
  6. 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.
  7. 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
  8. If it doesn't sell. I'm ok keeping it. 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
