I have had a loaner copy of the new Sony 400-800mm f6.3-f8 telephoto zoom lens from Sony Pro Support to try out for one week,
My 24/7 fulltime job now is taking great loving care of my 99-year old mom. So I have had to stay close to home and take some short trips, when I could, to a nearby lake to get some shots with this lens. Sorry no diving Osprey around right now, LOL, but some gulls, ducks, Canada geese and egrets, plus lots of boaters and jetskiers on Grapevine Lake, Grapevine, Texas, USA.
I shot all the photos here with this lens using my 50 megapixel Sony A1 II camera at various focal lengths between 400mm and 800mm, including using both 1.4X and 2.0 X teleconverters for 1120mm and 1600mm focal length shots. I handheld the lens/camera combo for some shots, but most were shot atop a Sirui Rapid System SVM-165 monopod.
Though the lens is bigger and heavier than its sister lens, the Sony 200-600m f5.6-6.3 lens, this new lens has similar design and functions, and handled and performed superbly. The A1 II has quick subject acquisition, and fast and snappy autofocus with this lens and its linear focus motors. The lens is very sharp, has a short, less than 90 degrees full zoom range rotation, and all the function buttons you need. IMHO it is a winner in every way, including value for its reasonable price. I hate to be sending it back to Sony.
Photos were shot in compressed raw format on CF-Express Type A memory cards, and processed in Adobe Lightroom, with some getting some noise reduction from Topaz Denoise AI software. Click on each photo to see full frame.
