I have no idea where "prweb" got that "almost equal" information from. As far as I can thell, they are the only ones that describe it as such and have shown absolutely no data to justify such a claim.

You can read the original Pentax article at Pentax Imagining.

Thank you

I guess you're right then!

Strange wording for a press release, I can see why everybody else (online retailers, etc) chose not to include that sentence. I also wonder then why they wouldn't put their best coating on a $7000 / GBP 6000 lens...

Guessing here.. there is probably a limit to how much gain Vs cost with nano coating technology i.e aero brite or Nikons 'Nano Crystal' I would assume you can achieve a better response with a slightly less light transmission but smoother coating on large elements.

Maybe if they'd gone with Aero we'd be talking RRP $10,000 that'd make us squeal even more like stuffed pigs.

At some point you have to assume manufacturers know what their doing and web 'experts' well are just hot air and bluster.

On the plus side web experts do tend to be better informed than Manufacturer PR teams but when said web 'experts' starts using sale blurb to back a derelict point well ..............
