I've had my trusty 400 f5.6 lens for many years now.It's a bit battered but seems to still operate OK with my 7D mk.1.
However in a hide last week I overheard some birder say that lenses should go back to the manufacturers for a service on a regular basis.Never heard this before and I wonder if this is true.
Any comments would be appreciated.
