Re: Playing around with depth of field and I think I finally get it?

I thought I would share some links to a couple interesting articles I have read today. I stumbled upon smooth trans focus lenses and defocus control lenses sadly even if you own a camera for the respective lens mounts so they are quite expensive

Adding a last article here. I found out someone has been able to emulate the effect of a smooth trans focus lens. Their findings are pretty interesting.

This was a very useful review and test of the105mm f/2D AF DC-Nikkor it explains how defocus control works. Its also a crash course in depth of field!

Now defocus control changes spherical aberration of the lens while smooth trans focus uses what they call an apodization filter.

Here is more information of how defocus control works.,by%20a%20slightly%20movable%20diaphragm.

Good article about apodization filters. The wikipedia page was over my head this explains it better.

Oh and here is an interesting review of a smooth trans focus lens it goes in depth about bokeh.

I also found a dpreview article about this lens.

Now according to wikipedia there was a camera made by minolta called the Minolta Maxxum 7 that could emulate smooth trans focus by doing multiple exposures using different apertures. According to Wikipedia this has not been done since in any camera.

I found this articles discussing the cameras emulation.

They sell these cameras for around 300 dollars on ebay. Sadly I cant find any sellers that will ship to Europe. Otherwise id probably pick one up just to try it out.

Lastly I read up on soft focus and frankly I'm still not sure what makes it different from bokeh. But I did discover that there is a lens legendary for its soft focus that was made in the 30s by Leitz apparently they released an updated version in 2017. Here is a review I found its pretty interesting.

The old version sells for about four thousand dollars on ebay and the 2017 version for about seven thousand.
