Isco Gotingen 50/1,9 Zeiss planar 50/1,8 & Zenitar 50/1,7

Time to compare these 3 50mm. well maybe it's nit fair as planar isn't good shape, while 2 other is in good condition
I just took this set few minutes ago. same speed 1/80 ISO 800, in front of my Asus, available light, setting portrait.
Interesting result

Kiron 105/2,8 MACRO & Leica Elmar 100/4 macro on NEX

This is not scientific test, that's kind of boring test for me :D so it's not represent all copies of both lenses.

My friend allow me to test his Leica elmar 100/4 macro non bellow version against my Kiron 105/2,8

Leica said to be 1:1,75 maginification, while Kiron 1:1

on body it's written 0,6 mmeter MFD, but it can be turned to closer ( about 0,5 in Kiron) 

Kiron has 0,45 MFD

Over all Leica has better control of light & lower contrast while Kiron high contrast & little bit sharper

kiron

 I forgot which one is elmar/kiron in 2 photos below, can you distinguish them?

I shot some of this dragon fly, but it cannot be good for comparison 'coz it was in different place also  different setting, but I think Kiron is sharper

that's the closest can go for elmar, here's closest of Kiron

Carl Zeiss Jena Flektogon 20/4 exakta

I just play with this lens when I saw A Fly  enjoyed chicken shit, it didn't move. So I took my macro lens, but when I came back, it's gone

Volna 9 resurrection!

Doing macro work with Sony NEX is really pain in the ass. This lens was rest for a while.
Finally I can use it properly

Isco Gotingen westrocolor 50/1,9 exakta

Isco often associated with Schneider as part of it. Actually it become part of Schneider after (if not mistaken) 1990. So this lens doesn't has relation with Schneider Kreuznach. Well this lens have a look like Schneider lens, bt perform different than SK Xenon 50/1,9, specially it's bokeh.
I like the look of this lens. Keliatan gagah, sayang gaada tutupnya
