This is the 53rd in a series of posts on the Fujifilm GFX-50S. The series starts here. Today the big brown truck brought a Kipon GFX adapter for V series Hasselblad lenses. I had had a total lack of success in stacking the Fuji H-to-G and the Hasselblad V-to-H adapters, and really wanted to test the Zeiss… [Read More]
Leica 280/4 Apo-Telyt-R on Fujifilm GFX 50S
This is the 52nd in a series of posts on the Fujifilm GFX-50S. The series starts here. Yesterday, Kipon GFX adapters for Leica M and R lenses arrived, so I’ll be testing some more. The timing is good, since I’ve decided that I really need to simulate off-axis bokeh, and I haven’t figured out a… [Read More]
Baby steps toward off-axis bokeh simulation
This is the eighth in a series of posts about building a bokeh simulator. This series starts here. I’m still struggling with how to efficiently program the off-axis bokeh simulation, but I did write some code to do a simulation with a static offset, if that out of focus (OOF) point spread function (PSF) is… [Read More]
Off-axis OOF PSFs of the Sony 135/2.8 STF
This is the seventh in a series of posts about building a bokeh simulator. This series starts here. Yesterday we saw occlusion of the iris diaphragm in the out of focus (OOF) point spread functions (PSFs) of the Zeiss 85 mm f/1.4 Otus and the Zeiss 85 mm f/1.8 Batis lenses. Today, I’ll show you… [Read More]
Adding off-axis imaging to the bokeh simulator
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]
