3x 1200mm (2x fixed, 1x zoom)
The shorter lens in the background is the AiS 1200mm/11 ED
In the foreground the older K 1200mm/11 lens head with a focussing unit. As I later realized through Roland's list, happens to be the first produced (80 in total). Is part of the flexible set of 4 lens heads (400mm, 600mm, 800mm, 1200mm) with the extra focus unit Nikon offered in 1975. It is still a very good optical performer these days. The MFD of 45 meter limits indoor use a bit and the size and shape triggers fun conversations with airport security people at the security gate
If used with the 2x TC, a pentapod is recommended though (i.e. for a moonshot. Combined with a DX camera, the moon is way too large to fit on the sensor
)
AiS 360-1200mm/11
The zoom is the better choice for candid shots of other photogs (candid by possible distance that is). Haven't tried dynamic street photography with it
