I've been playing with some rear-projection TV lenses on and off for a few years now. Since I wanted to achieve infinity focus on an SLR camera, I had to seriously modify a few of them. So far, my best is an 80mm f/1.3½ that fits on a Nikon. The results are dreamy and bloomy while retaining a certain amount of sharpness. Pretty unique.
Cooles Projekt! Habe hier auch noch einen Karton herumliegen mit alten "rear projection lenses" Sony Delta 88 ML, die haben auch f1.0 oder f.0.95. Habe bisher noch keine vernünftige Verwendung dafür gefunden.
@@mhaustria nein, aber was soll das bringen? Habe überlegt die Linsen für ein Astrofoto Setup zu nutzen aber wegen den chromatischen Aberrationen hab ichs gelassen. Hab sie auch zum Spaß mal vor die Kamera gehalten und du kannst mit dem Ding echt Nachts sehen.
@@DanielSchweinert Ich hab da so eine idee und werde mal was ausprobieren. Ich denke auch, das so ein Teil nicht mehr viel schärfe auf einen digitalen Sensor bringen wird.
@@mhaustria Coatings? Does the lens actually give a yellow cast when you look through it? I had a lens once that I thought was radioactive for a bit but it turned out to just be a yellow coating.
Hallo Markus, krasses Experiment! Danke für Deine Videos! ich plane eine ULF-Kamera zu bauen. Ein Teil, Ein ersatz für den Balgen, habe ich schon. Meine Frage ist, welche Objektive würden sich dafür eignen. Hast Du eine Liste, Übersicht dafür? Wäre schön von dir zu hören!
Servus, kommt immer auf die Größe der Kamera an und ob du Porträts oder Landschaft fotografieren willst. Ich hätte eine sehr günstiges 400mm abzugeben,m. Für Porträts sicher ausreichend.
Thank you. Camera building at that level is sometimes easier than you think. Have you seen my diy camera video with Corrine? I offer these camera build workshops including a wet plate workshop.
@@mhaustria I need one for collodion, but, perhaps when the war is over. Until now I'm gonna stuck to my 4x5 and printing gum bichromate with soil. But when the madness is over - would be happy to learn collodion on one of your workshops.
@@mhaustria I'm in Kyiv at new not normal normal, thanks. Doing my war times album - documenting (4x5 and soil prints) my family going through that. I have a video here on UA-cam you can check it if you interested.
@@mhaustria terimakasih.. saya akan mencari lensa ini di di pasar loak, harganya sekitar 10 dolar di tempat saya.. saya pernah bereksperimen dengan lensa hd 6C 130mm F1.0 di kamera mirorlles saya dan hasilnya sangat memuaskan untuk potrait.. terimakasih untuk informasi lensanya 🙏🙏🙏
I'm sorry, but I'm so very disappointed by use case you decided to have with this lens. I mean with that kind of f number and angel of view (ultra-wide), why would you go for a close-up portrait?! Wouldn't astrophotography be the perfect application for that lens-sensor combination?
That’s actually a great question. When you watch the video you see me focusing the lens at infinity. Then the image circle is just as big as the end diameter of the lens, and I only could have done a 4x5inch plate. But I could not mount the lens on any of my 4x5 cameras. To cover such a big plate, you need to focus on something very close. Watch the drawing with the sensors again and it will make more sense then.
I would love to see this in some kind of landscape use! Great video. Keep them coming !
I agree, but then I need to shoot tiny plates. Because the maximal image circle at infinity is the diameter of the back of the lens. Thanks a lot!
The fasted lens i have for 16x20 is an 19” f4.5 portrait lens .
Without a shutter it’s not so easy to use

great stuff! How did you modify them? Did you remove a glass element?

Wow this is incredible, I love how involved the whole process is and how much thought must be taken compared to digital
Thanks a lot. It’s very different to focus together with my sitters for only one shot
Wow turned out great!
Thank you!
Time to take it to the beach for a seascape!
maybe also underwater images :)
That is a huge lens!
Good work adapting to the lenses size, the huge plates and creating the final photo!
Thanks a lot! Yes its really big and took some time and energy to put everything together
This is a really interesting VID. I have a few friends who are wet-plate photographers. I shall pass this VID along to them.
Thank you.
Thanks a lot and very welcome :)
Wunderbar! Danke Markus!
vielen Dank!
Super Video, bin dankbar was neues gelernt zu haben.
Vielen Dsnk!
Bald gibt’s wieder ein lehrreiches Video
Absolutely crazy, and awesome.
Thanks a lot!
Great video of an interesting lens. I need to learn how to make that AgNO3 wave inside a tray.
Thanks a lot! The easiest way is to get a tray that is twice the size of the plate. This tray was a bit smaller...
Thats awesome!
Thanks a lot!
A beauty !
Yes she is, I am working on her little sister now
Thorium in a 1997 lens??
That is a great question. I am not sure about it, but is very yellow and the second one is not. Any idea what else this could be?

Very interesting. According to you what focal length would it make on your 11x14mm? Portrait?
I guess it would be in the neighborhood of 2mm
unique content!
Thanks for that comment, I don’t think many work with this kind of combination like I do.
What would be the largest format you can focus to infinity with this lens?
The diameter of the lens, because it’s designed to project a crt screen that is very close to it
Cool lens. :)
My fastest lens is a 420mm f/3.6.
That must be a big one as well
wow, makes a great macro lens, how about some more.
you are right, that short focal length is good for macros, but the shallow depth of field and not aperture makes it difficult
off topic - you just made me buy a Super Nintendo to play on my projector 😂
I hope you used an affiliate link ;) hahaha
Apakah ini lensa Delta hd 8 Rev B? Kelihatan sangat besar ukurannya.. bisakah anda memberi tahu saya type lensanya?
It's a HACC PT-43 Lens - As far as I understand HACC stands for High-Resolution Aspheric Color Corrected Lens.

@@benyaminsahabir5994 Sounds interesting. Have you shared your portraits somewhere? Would love to see them.
@@benyaminsahabir5994 Hey I was also looking into shooting this lens on my mirrorless camera, would you post any samples of your results?
Eso es genial!!
muchas gracias

Thanks Gabriel!
Ummmmmmmm... 😳
can I borrow it for some astrophotography? 😂
Do you want to check out Mars? ;)
