I tried a few different setups to photograph the Harvest Moon on October 1st. I was setup in my sunroom shooting out the side door. So I lined up a few teleconverters to try different combinations to see what combinations would work or not work well. The combinations of teleconverters is also based on which teleconverters would actually fit and go together in stacking because of protruding lenses or openings around the lenses in the teleconverters. In all I used 4 different brands of Teleconverter for my tests & 5 different teleconverters. I usually would use my 400mm f/4 DO lens but I loaned that to a friend so I was using the Tamron 150-600mm @ 600mm with the Teleconverter combinations. I was just curious of the quality of the images with different combinations of Teleconverters. The Featured Image was shot @ 600mm with a 2X Teleconverter.
