Judging quality by brand names is IMHO pretty pointless. Someone compared a certain filter brand to a Rolls Royce car - which to many is an expensive status symbol with very questionable (and historically unspecified) performance as a motor vehicle.
I wouldn't be surprised if some no-name and some "luxury" filters were indistinguishable in blind tests.
This kind of arguments about branding has a certain aura of "wisdom" which on inspection shows, well...............I hesitate to put into words my thoughts!
Is a Skoda more reliable than a Toyota? Do we need to argue on this? The idea of using "Rolls Royce" status is to confer an understanding that the product has a level of sophistication and reputation gained not yesterday, but through years of exposure to use and scrutiny.
If you think that judging quality by brands is pointless, address your comments to the thread starter and tell that it is nonsense. But that was not his concern, as far as the way the question is put forth.
Nowhere did I say that Nikon, Canon, etc cannot do the job. The question is, and remains, please read carefully, "what is the best brand....". If you have not read the question carefully, please put on your reading glasses, check the dictionary on the meaning of words, and have a GOOD look. The thread starter had asked for a "best brand". You can disagree with me and feels that "Brand H" is the best brand". It is your perception of what is the best brand. If you do not have an opinion of what is the best brand, then I think whatever you wrote did not address the question. Have you even begun to address the thread-starter's question in the most simple and direct manner? I personally use Hoya, Cokin, B& W, Tiffen, Lee, and also Singh Ray. And they all work! But there is little doubt that there are differences in quality. Just look at the rings holding the filters, and immediately one will see the difference! Singh Ray is a brand that is extremely well regarded. The reason why it is not as well known is the cost.
Likewise, any modern lenses are equivalent in sharpness. The image quality, particularly colors may differ among brands, and is a matter of taste. But some brands are just better constructed than others. Whether one consider this worth the extra money is a totally manner.
Even for computers! Most modern computers gets the parts from a few suppliers. Put them together, and a brand is made! But, and this comes from a friend (fairly senior) of mine who works in the computer manufacturing industry, the quality differs because some company (translating to different brands) have higher rejection rates from the primary vendors, prefering to give less trouble to the buyers, than offering free services to deal with problems resulting from a less than stringent quality control. And of course for this better quality, one has to pay a higher premium.
So please, do not say that branding has no relevance to quality. Whether you think it is worth the extra is your perogative. But a Rolls Royce remains a Rolls Royce. A Lexus is still not a Rolls Royce.
