This is the sixth in a series of posts about building a bokeh simulator. This series starts here. It’s become apparent to me that what many people talk about when they discuss a lens’ out of focus (OOF,  as opposed to almost-focused) bokeh is related to the off -axis occluding of the sensor’s view of the… [Read More]

This is the fifth in a series of posts about building a bokeh simulator. This series starts here. In the last post, I compared simulated defocusing to the real thing with the Sony 135mm STF lens. Now I’m going to do the same thing with teh Zeiss 135mm f/2 Apo=Sonnar ZF.2. Here’s a sharp image with an a7RII… [Read More]

This is the third in a series of posts about building a bokeh simulator. This series starts here. I took the out of focus (OOF) point spread functions (PSFs) from the 135 mm f/2 DC Nikkor and the 135 mm f/2 Zeiss Apo-Sonnar ZF.2, and put them into the simulator. You will note that the… [Read More]
