Can't say for sure. These are old files so I don't always remember. I don't use conventional telephotos, but scopes, so the exif info is no help.
I know the last one in the first group, the Red-bellied Woodpecker, was taken with the 560mm APO triplet. For sheer raw optical quality this is my best glass. Not much magnification (about 16x) but it has resolving power to burn. It easily out resolves the sensor on the K20D. BTW these were all taken on the old DL with the 6mp Sony sensor not the K20D.
Here's a shot of the glass I use.
From left to right:
1000mm FL 120mm objective achromat (30-60x)
620mm FL 100mm objective Pentax spotter (38x with Pentax DSLR camera adapter) I think the first shot in the first group was taken with this setup.
500mm FL 100mm objective achromat (15x)
560mm FL 80mm APO triplet (16-30x)
Here's a shot taken with the 560mm triplet and the DL:
