 p.9 #9 · p.9 #9 · Sigma 28-45mm f/1.8 DG DN Art Prime Comparison / Image Thread | |
Took a few quick handheld test shots yesterday on the SL3 after the lens arrived. These are all screenshots from Capture One full screen on a 16" MPB M1 Max XDR display.
This lens reminds me so much of the GFX primes, like putting the GF 30, 45, and 63 into a single zoom.
Unless shooting brick walls or architecture, the 28mm end looks much more natural and three-dimensional when left uncorrected for distortion. The distortion correction excludes too much of the frame and flattens the natural 3d look of the lens, IMO. The distortion correction also greatly worsens the slight midframe softness at infinity at f/5.6 and wider apertures (midframe meaning the four areas of the image halfway between the center and corners).
On my same display, this is the first lens/camera combination that looks great at 300% magnification at close distances wide open. The resolving power is impressive for a prime, much less a zoom.
I can't believe people think this lens is too big or heavy. I guess if you're used to the tiny Sony bodies with small primes, I can see where you'd be coming from. But having used the Canon R5 + 28-70 f/2 for a long time a few years back, this lens feels small and light. Sure, the Canon does 70mm, but Canon also can't seem to produce a camera over 50mp. The balance on the Sigma is also perfect, and the weight is not all out at the end of the lens.
The Canon 28-70 f/2 also has a severe flaw, which I call "dog ear" vignetting when shooting wide open at 28mm ("dog ear" meaning how one folds the corner of a page of a book as a bookmark). This kind of vignetting can't be removed without a lot of effort in post. The vignetting on the Sigma is gentle and subtle – it isn't even corrected by default in Capture One. It vignettes like a lens designed for a larger sensor.

(for me)
). Over the past 3-4 events I'm shooting thousands of frames all in AF-C of whatever is going on around me. If it is of a single person I don't think I get close enough at 45mm to have to many DoF issues wide open. If I misfocus I really miss, my movement or subject... When I cull for the studios I do a very rough edit cutting 50-60% out just trying to keep what is in good focus so they can cherry pick without having to verify sharpness. I use Narrative Select which will zoom into all the faces but not eyeballs specifically. I have to do that manually.
