Originally posted by luftfluss What did I "fudge"? Are you accusing me of doctoring the graphic I posted? I just went to the DXO page, picked the 2 lenses you had pointed out, and ensured the same camera was used for testing.
And to counter this I went to DxO and picked a faster zoom, because I know from research, with different lenses on the same system, DxO scores, the fastest lens better. All I had to do to show a different result was use a zoom that is faster than the prime you picked. You compared a faster prime to a slower zoom, so of course you showed primes are better than zooms. I went to a zoom that was faster than your prime and showed zooms are better than primes. If you want to counter again, just go to the Sigma 35 1.4 and using DxO you can once again assert primes a better than zooms. The problem is that the way DxO scores are compiled, that is the result you get. If you are trying to find our which lens will give you the best resolution and IQ, DxO doesn't tell you that. It tells you which lens will give you the best result, if you shoot in your mom's basement.
So no not doctoring the graphic, but using a graphic that doesn't mean what you claim it means. The numbers I quoted from Photozone if you read the text, you'll realize, the same camera was used for testing as well.
But if I wanted to show zooms were better than primes , I would compare a DA 35 2.4 to a Sigma 18-35 1.8. And DxO would tell you the 18-35 was better. Even though at ƒ8 on both cameras, the 35 2.4 might be better. DxO is pretty much worthless for this type of comparison.
