Hi, I should have said that I was looking at used telephoto lens prices here in the UK, and yea, used could mean a big price difference I suppose but no photographic supplier is going to sell any used lens that is in any less than very good condition, or that they would have not fitted it to a camera and checked the functions and photo quality etc.
Bearing this in mind the suppliers selling these used lenses were Clifton, Park, and in the main,
MPB Europe.
The price differences were as follows :-
Nikon AF-S Lenses Canon EF Lenses
300mm = £2829 300mm = £3079
400mm = £1599 400mm = £5219
500mm = £3699 500mm = £5799
600mm = £3129 600mm = £6259
This I assumed to be the normal price difference across all lenses, either new or used, but after your reply and looking at the prices of general zoom and prime lenses you are quite correct. What is it then that makes telephoto lens prices so unequal ???? especially the 600mm.
If I am missing something please put me straight.
With thanks.
Thank you for replying to my confusion.
