Some of the adverts for these have different specs. Are they BAK4 or BAK7 lenses? Are they IPX7 or IPX5 waterproof? Are they nitrogen filled? I might be buying some of these if the specs are OK for me.
They are surprisingly high performance like many premium brands that cost say 3 times as much. Optically is great and I'm quite fussy myself. I have a pair still in the box if you want them at a bargain. Cheers
@@jeffwong6368 Hi Jeff... Could you please clear a few things up for me before I decide to purchase this model. The adverts I see on ebay and Amazon are confusing. Are they Bak4 or Bak7 lenses? Are they IPX5 or IPX7 waterproof? Are they nitrogen filled? Many thanks Ernie
