I was at a party on Sat and I took some pictures with my new Sigma 50mm 1.4 Art Lens for Nikon.
On Sunday I noticed some artifacts on some of the images when I shot vertically like rainbows in the shadows and people's skin. I've never seen this before so I trying to determine if the cause is
- The D3s
- The Sigma lens - I hope not since I just bought this
- The B+W 77mm UV filter
- SB 800 Flash
- A combination???
I spent 3 hours yesterday trying to duplicate the CA, Moire or horizontal artifacts at my house but the environment is completely different so it' s like comparing apple and oranges.
How you seen these types of artifact before? What might cause it? Extraneous light, faulty lens, low pass filter??
I've seen CA, but not this bad if that's what it is. Certainly not the rainbows. Look at rainbow on the ladies left leg and in the shadows.
Please let me know what you think??
Had to severely crop the pic!!
