Polarizer Help... To MultiCoat, or NOT!?

Ive been looking at Hoya CPLs for my 77mm lenes.

I have the cheapest Hoya for my Tamron lens which seems to work just fine IMO. (Green Series)

The 77 is getting used with my 10-22 and the 300mm f/4 lens. I was thinking of getting the same Green Series (non coated) CPL

Can anyone really vouch for the "addition peformance" of the super freakin expencive $100-$150 CPL units? Is it really worth having that multi-coated options?

I find some killer deals on ebay for the Green version.. Ive also used it before and dont really have a problem with it, unless I am missing out on stuff I dont know of.

Thanks

I figure I ask before I hit my ebay checkout.

Multicoating will reduce light loss by reflection at the air-glass interface from around 7% to almost none (granted, 7% light loss is on the order of 1/6 stop) and also reduce the likelihood of internal reflections causing lens flare from stray light striking your lens and/or filter. If it isn't multicoated, I don't use it.

As Jon stated, the single coated Hoya transmits about 93%, the multicoated Hoya transmits 97%, the super multicoated Hoya transmits 99.7% of light. What is not transmitted will materialize as flare or lost contrast.

Ahh, and now I understand...

Sigh... guess it goes back to you get what you pay for haha.

I figure this was going on my 10-22 or 300mm f/4 L so I might as well pick up the super. I dont want any loss in contrast, resolution and or flare...

An additional issue, which has only arisen with the advent of digital photography is that the sensor reflects light back out the lens. It's not some black hole - it's a reflective surface.

So the coating is also designed to let light pass through OUT of the camera unheeded.

This is the same as with many L series lenses, they are also designed to eject light from the lens with as little resistance as possible.
