Thank you guys! A few weeks old, haven't had time to show it.
Not that many flowers left, got cold and rainy here.

Lovely stuff!
Admit it, you are more about art than science.

We've had snow this week, so no more flowers, or green grass. Sad
Nice shots.

Nice pictures Klaus.
I happened to have the Kodak Ektar 103 mm with fixed aperture and tested it some time ago while stacking cacti flowers:

Nice pictures, but it is not the same lens! "Kodak Printing Ektar" is not a normal "Kodak Ektar" and even between Printing Ektars, the heavy brass ones with 7/8 lenses are not the same as normal Printing Ektars

After seeing Klaus's shots with the 100mm f4.5 Kodak printing Ektar I just had to have one. Rolling Eyes

macheck your photos are different than klaus. i was wondering did you use photo editing. sorry klaus i should have identified. who had the different images. between these photos, macheck has a slightly different appearance. that why, i was wondering if there was editing used by anyone. all these images are excellent. very well done

Congrats, but it is a 101mm f4.5 that I also have shown Chris here (a TESSAR 4e/3g design): http://forum.mflenses.com/kodak-printing-ektar-f4-5-101mm-tessar-type-t72832,highlight,%2B101mm.html not the one in this thread here (which is a 7 or 8 element type lens). Of the same type there is also the Kodak Printing Ektar f3.8 89mm which I have shown here in 2011: http://forum.mflenses.com/kodak-printing-ektar-3-8-89mm-t43814,highlight,%2B89mm+%2Bektar.html

Mine is definitely a 100mm f4.5 Kodak printing Ektar Klaus, what is the difference between this and the 101mm you posted? Regards

Chris, some say the 100mm f4.5 is a Dialyte (4e/4g) design and the 101mm is a Tessar 4e/3g design. HOWEVER a well reputed French lens analysis site (of Mess. Eric Beltrando) states on http://www.dioptrique.info/base/n/n_ektar.HTM that the 4.5/100mm Ektar is a 5e/3g HELIAR (which should make you rather happy, as a Heliar is a great sharp lens with verfy pleasant bokeh IMHO!)

The 2.8/103mm Printing Ektar which I showed above is a modified Double Gauss 7 lens in 3 groups (7e/3g) design (I have the patent literature...)

These printing Ektars seem like wonderful lenses capable of producing wonderful images in the hands of a master like Klaus! Beautiful images.

By the way, am I correct in assuming that the printing ektars were used for such things as optical printing of cine films, or in automated photo finishing equipment, or maybe even in commercial printing.? All these tasks I would think would require very high resolutions and peak performance around 1:1 or higher magnifications, and quite possibly a flat field? I don't understand how this results in such beautiful bokeh.

Thank you! Indeed, they have been used for printing paper prints and also cine film to film printing and sometimes with some format conversion, hence I think why there are different focal lengths and given (i.e. printed of the lens) optimized magnification ratios.

The 103mm is optimized for 1:1 and the 89mm is a 2:1 version


and a 88mm one in 1:1.8

Photos of mine are stacks of several single pictures (it is explained) so I would say heavily post edited by a stacking software to gain deeper depth of field.
I didn't find anything special in my Kodak Printing Ektar when taking pictures from a distance so gave it a try in closeup stacking where uniform sharpness of whole frame is most desired.
