Well, the Sigma 50 1.4 is starting to hit the streets, so rather than spread images all over the place, let's go ahead and start posting them here. The "Sigma Announces 50mm F1.4 EX DG HSM" thread hit 50 pages before we started seeing sample images. Let's keep this thread focused on images. If you want to talk about the lens itself, there is 50+ pages in this thread that discusses the lens from every different angle.

Is #2 a 100% crop of #1, or another picture just closer up?

Taken from the "Sigma Announces 50 1.4" thread..

This gentleman was one of the first to start posting samples of the Sigma 50 1.4, with comparisons to other lenses. This was our first "real" look at the lens

[WARNING] Maro did not compress the images, so the page takes some time to load (he puts images for all of this lens on it). Have patience[/WARNING]

It's the flower in the center.

Put the lens on my 40D to compare with my sigma 30mm 1.4 - Looking at that image and others I took, the 50mm has better tone and stuff. Looks more like the images out of the 5D.

The left pic is the 30mm... Had to step back about 6 ft with the 50mm... Not my car...

Hmm, the 50 does look it produces richer colors over the 30 1.4. I can tell the difference in the yellow of the vehicle.

i can get the same results from the same lens in back-to-back pictures. i'd have to seee waaay more pictures before i'd even begin to draw any conclusions :D.

If you look at the light and shadows on and around the vehicles then seems the available light was very similar while you took the images. The subject and background all seem richer and more naturally saturated with good sharpness and contrast. Seems you got a nice lens there.

Remember guys & girls & whoever :cool:

Always ALWAYS try & post samples with 100% crops as well, posting rescaled images is fine for checking out contrast & colour, along with viewing the entire scene, BUT we arnt interested in the photo itself but the lens, so we really need to see the level of sharpness & to check for abberations, this cant be dont with a full frame resized image, we NEED 100% crops..

Thankyou, I feel better getting that off my chest :p

And not just that, we need those 100% crops to be from both the center of the frame and, if the shot's taken with a full-frame caerma, from the edges/corners (edges/corners from a crop camera won't mean all that much since the lens is designed to be used on a full-frame camera).

Ideally, someone with a 1DsmkIII will put this lens on it, put it into live view mode, and zoom into an edge or corner and manually focus on that spot until it's as sharp as possible, then take the shot wide open and show the results. That'll show what the lens is capable of in the edges/corners.

Live view might not be very useful for a lot of people, but it's a lens tester's dream. :-D

The shadow under the car on the 50mm image looks much sharper. Like the sun was brighter and beaming straight down. The 30mm image look more like a cloud passed over and diffused the light.

yep. a little cloud movement could easily explain the difference. like i said i would never make such an assumption with so little info.
