I got a comment as a suggestion for my words about C-Biogon 2.8/35 - "coldn't feel weight of the objects." It says - "..I wounder how it would be like if the colors are more vivid and bright."
Here are two images - one is 'vivid and bright', one is 'vivid and darker'. How do they look like?
Now then, it might be curious about the differences between other Biogons. I would like to put some images on the next topic.
