So I was out last night making some IBIS stills tests and had on my RF 15-35mm lens. One of the photos I took shows some weird issues I'd like some opinions on:
This is a crop of the image, original was 15mm so this isn't edge of frame stuff. The focal point is somewhere above the right car, on the text in the window - looks fine. But then scan to the left and look at the writing in the window over there. Blurry - why? It's on the same plane as the writing I focused on. Same question on the 'for lease' sign.
But also - a dead giveaway, look at the rear wheel on the car in the middle of the frame - looks round. Then look at the front wheel on the car immediately behind it. Oval:
full size for reference:
I know lenses this wide have some issues as you go out from the middle, but these seem excessive? Thoughts?
