Sigma 60/2.8 & Roller Derby.
Got a chance to try out the 60 last night @ a scrimmage.
I switched to the Oly 45/1.8
The low light made the shoot difficult & I found I needed 1/400s to freeze the subjects, thus high ISO & lotsa noise. I tried Denoise on the first 2 images here & Lightroom for the rest.
All in all, not a good outcome with this shoot.
The wood is clear between the knots.
