if third party lenses are now being tested with IQ just as good as the "overpriced" canon lenses then why complain about canon's pricing? just go buy the third party lens and be happy.
its as if deep down inside you want the canon lens...but why? if the third party lens is just as good but cheaper....
I agree with this statement completely. Personally, I am extremely interested in the new Sigma 35mm 1.4, and my purchase will depend on how this rumor pans out. I also think the Sigma 50mm F1.4 is an excellent lens, especially considering the price. I don't think anyone is arguing over which lense gives you more for your money.
That's when you need to step back and remember not everyone has the same budget as us. Sure, I can't afford to drop $1500 on a new 50mm lens right now, but that doesn't mean others can't. Just read this thread, one said he would gladly trade in his 16-35 and $3k for a single UWA. Great for him, if he can afford it, and the new lens suits his needs. Just because I can't afford it right now doesn't mean everyone else has to make purchases bsaed on my budget.
If you absolutely need F1.2 and weathersealing, what other options are there? You can complain all you want about it being overpriced (And I agree, to an extent) but that doesn't change the fact that the people that need F1.2 and weathersealing don't have any other choice. We can happily buy the Sigma (Actually, I won't, I'm worried by the focus shift... waiting for the canon 50mm 1.4 replacement) and they can happily purchase the canon version. Everyone wins.
