Also true. But the EFFECTIVe focal length (determined by the actual mag number) is only one parameter. The opening (the huge, or not-so-huge, chunks of glass at the front) is another, and it is equally important, so it makes no sense to leave that out.

As I said, the combined effects of the parameters are enough to make hardened criminals break into tears. There is so much crud involved, it's not funny. Take two identical scopes, forget to coat a few lens surfaces in one, or economise on the coating of all of them, and the resulting differenceis are nothing short of dramatic.

\Anyway, we all agree on one point: go and have a look at the actual scope rather than at the numbers.
The Filthy Pig: Air Arms 100 (1990) + AA Olympic trigger + Welham reg + Custom Shop CS1000 stock. Status: leaking.
The Unknown Quantity: AA EV2 Mk4. + BSA Platinum 10-50x60 + Jon Harris wheel. Status: sorted up to 25 yds.
The Limping Dog: Air Arms Shamal (1989) + unknown origin sporter stock + Optisan Cobra 3-9x42. Status: slowly leaking; needs work.
The Ox: HW97k + Venom Lazaglide. Status: working just fine; needs scope.
with apologies to NJR100
