I worked all Christmas day doing street shoots, day sunlight, night light. Also finished shooting colored backlight flare tests yesterday. Now edit and upload are next tasks.

@apefos

Love it! Is that the gold coated one?

Looking good. I keep going back and forth between ones I like.

Yes ive started but diferent aproach, please send images for get better idea

@endotoxic

I will upload the new videos, so you will see the flares in day/night street shoots and also with colored backlight.

But maybe your approach is better, trust your idea and show us.

This video shows some imperfections in the Apefoscope optical system. It is not that bad, some people even don't care about, but it is noticeable by trained eyes. It is important to say this is not generated by the lens coating, it is generated by lens grinding process.

As you can see, the optical lab I am working with cannot do the same quality grinding in all lenses. In daylight bokeh shoots this becomes unnoticeable because many parts of image is out of focus. Also stop down the taking lens diaphragm a little bit helps to improve image quality when everything is in focus and the image looks good. But at night I need to open the diaphragm, so the imperfections shows up. Only solution for this would be a CNC (computer numeric control) lens grinding. At this moment this is out of my resources.

The optical lab cannot do the lenses in same shape every time. The lenses always have the same power and squeeze factor, but the alignment between the surfaces always have a small difference from one adapter to other. They improved the difference from the previous 2.3mm thickness difference to 0.8-1.3mm difference. But this still can cause a small decrease on sharpness when using fstops like f2.0 and f2.8. I do not have resources to do a perfect lens without differences, so people who buy the adapter must deal with this.

The optical design in Apefoscope could do f2.0 bokeh shoots no problem if the lens grinding could be perfect and everything in focus in f4 or f5.6. But with the lens grinding I can get today I consider the adapter good to do everything in focus from f8 to f16 and to do out of focus bokeh from f4 and above. Some units works good at f2.0 and f2.8, but not all units, and if I start to dispense / reject lenses just to use the very best ones, the manufacturing costs will increase so much.

I will upload a video showing shoots from f1.4 to f16 with 5 different adapters and with no adapter, bokeh shoots and all in focus shoots.

@endotoxic

In this post there are two images showing the lens front with oval shape.

The problem is: the Apefoscope does not generate oval bokeh, The bokeh is different from the taking lens bokeh, it has some kind of anamorphic bokeh, but it is not oval. If we promote a logo with oval shape people will start to believe they can get oval bokeh with Apefoscope and it will generate false expectations. So I don't know if put oval shape in the logo would be a good idea.

@endotoxic no problem, two minds together works better than just one!

This video shows what happens to the flares when changing the diaphragm fstop and changing backlight intensity.

the project is finished and successful, just waiting the logo from @endotoxic

@Jean71

Happy New Year

no problem if you do not want to buy. Its fine.

@everybody

I need to say I just sent one more message about the project end, and some units ready to ship. From now no more private messages. I also asked in the message for people do not reply in the message to avoid spam.

@Vitaliy_Kiselev

The project is finished and successful.

I think this topic can be closed after @endotoxic show us the logo. So the buyers can open another topic for "user discussion and opinions"

@tonalt

He got my PM, next attempt will be last one.
