The most absurd diffraction spikes I have ever seen

[buoyant granite]

i love iris diffraction spikes, they look so funky, but like so satisfyingly like drawing the sun as a kid haha

[grave geyser]

hahahaha yes that is a perfect discription lol

these spikes are caused bc I there are 9 straight aperture blades in the lens

[buoyant granite]

yeah, i figured. My 300mm f4 af ed has the same number iirc and it is lovely

If those are the most absurd spikes you've seen... You haven't seen many astro photos lol. I've seen much more obnoxious lol. I recal hearing similar remarks on my Rokinon 135 images. Once they learned they are natural from the blades, they kinda felt silly. That aside, it's one area where step-down rings have advantage, can step down aperture and reduce diffraction.

tbh I prefer diffraction over blanc round stars
