There just is something to this wicked TTArtisan 100/2.8 2x Macro lens... (for Fujifilm GFX camera) which i think has that special flair of poetry. It appealed to me in a profound way. Actually it appeals to me even more as a close-up lens, than using Mamiya Sekor Z lenses in the close-up range.

This lens has that classic "mediumformat" background blurriness which is convincing. I wonder how this looks with various details of a human body... Another classic mediumformat motive... You focus on something particularly - while the rest of the body or pody parts transitions into beautiful blur (a blur that still shows coarse outlines, but in a poetic way / Instead of going into a total diffuse type of blur - which i consider to be different in character). Mediumformat blur often shows some outlines, instead of being totally diffuse.

And that is a key factor in the "bokeh quality" with (film) mediumformat cameras/lenses.

Stopping down (a little)

I also noticed that the 12 aperture blades keep the highlight "bolls" always round. So, when i stop down from ƒ2.8 to ƒ5.6 - the background remains beautiful, but the sharp details gain definition - without taking away the background too much. (sometimes when you stop down, the background becomes too unsettled).

Actually, it is a bit surprising, that the background blur with the TTArtisan 100/2.8 Macro lens remains intact for quite a while. You would have to stop down to ƒ11 in order to see a far more pronounced difference.

When I do the same things with Mamiya Sekor Z lenses - the background becomes much more pronounced, already when i stop down 1.5 stops.

Intriguing and strange.

Elusive, too.

It all starts to fall in place

It appears to me, that the Mamiya Sekor Z lenses are working best for me, when doing portrait / studio photography sessions. And for that, they do perform admirably well. The way i arranged them on a rail in order to focus, i also can in a very easy way shift the camera between horizontal and vertical positions.

However, I find them far too bulky for outdoor photography, or outdoor close-up macro photography. The TTArtisan 100/2.8 macro on the other hand - is far flexible due to its much smaller size.

The Pentax 6x7 lenses can act for me as both Studio/Portrait photography, Vertex 7x7 cm sensor photography, as well experimental photography.

So, these very different lenses - all start to fall in place - which areas they are best used for.
