Thank you Colin, yes the 300/4 is holding up
For some reason I mainly shot with this combination of lenses but the absence of VR gets the iso to 1600 for hi shutter speed so the outcome isn’t so pleasant
Nikon 200-500 has better overall IQ and VR but is heavier and bulkier
What about 300PF did you show any difference with various TCs compared to AF-S 300?
