I will try to upload test photos - it will be my first upload so i don't know if it will work.

Made with Pentax K10D, 200 ASA, jpeg 10Mb. Aparture wide open. I will show full photo and a cut that will be resized on 60%. Some sharpening applied.

@ Pancolart:

I've marked Ingo's schema to show you what I mean - I've looked at the Orestor 100 I've got disassembled and it's identical to the schema :



The parts marked with the red asterisk are impossible to wrongly fit - the cemented pair can only fit one way into the large inner barrel and the other element is bonded into the smaller inner barrel which itself screws into the main lens body so by default will be correct.

As long as both the larger and smaller inner barrels are fully screwed in and everything is correctly seated, this leaves both the front and rear elements as the only ones where mistakes can be made and it's the rear that's most likely.

However....

Although 100% crops would be better, based on your sample images of the lens wide open and assuming you're getting proper infinity focus, it looks very good for a 40+ year old design.

I'd be happy with it anyway, especially considering it's at f2.8. Wink
