Re: Lenses

Agreed.
The 50/1.4 is going to produce an advantage over the 50EX

The 20D has a big lens advantage in this test. The 50/1.4 has much
better color balance, no yellow cast (both evident in your pics)
and is significantly sharper than the 50 EX at all apertures.

An f/11 comparision was a good choice, but if you do nothing but
compare X3F file sizes at the aperture, the 50/1.4 might produce
about a half a MB larger X3F than the 50 EX file, all things equal.
That is about the closest they get.

I can offer you a 50/1.4 loaner for Sigma SA, but I don't know how
well, quickly, or even if it would make the trip.

20D + 50/1.4:

SD10 + 50/2.8 EX upsampled to 8mp:

Both shots made at F11, 1/200, ISO100.
20D shot saved from C1Pro, low noise reduction, no sharpening.
I saved SD10 shot double-size from SPP, then resized to 8mp in
ACDSee. I also tried saving same size then bicubic upsample in PS,
but got absolutely identical result.

Neither is adaptive like the 20D's upscaling routine.
