Apefos Scoperama Anamorphic Adapter Development Topic

Vitaliy_Kiselev

lens coating was developed to avoid unwanted reflections in optical system.

I though that main goal was to improve light transmission.

The lens coating does not change the color of the light which pass trough it, but it can change the color of the reflections due to the colors of chemical elements used to build the coating material.

Looks like both statements are incorrect. Last one - about "colors of chemical elements" is just bullshit.

@vicharris thank you! probably you are my most constant follower.

@silvertonesx24 did you mean uncoated x coated?

lens coating was developed to avoid unwanted reflections in optical system. When a light ray reaches a transparent surface, some amount pass trough and some amount are reflected. In a photographic objective with many glass elements this would make the system completely unusable due to lots of reflections, so the lens coating was developed to avoid reflections and solve this. The Apefoscope does not have many glass elements, so the uncoated version is usable and it has an unique feature, keep reading to understand:

In a spherical system the light spreads in all directions and the reflections get a circular shape. In a cylindrical system the light spreads in just one direction and this forms a line, this is the behavior of reflections in an anamorphic adapter. Sometimes an issue turns into a good feature. In cinema this is common. 24p strobes but people consider this the film look. Anamorphic reflections gets a horizontal line shape and people consider this the film look also.

So the goal in the lens coating for an anamorphic system is to smooth the reflections without delete them completely, to make them less annoying, but keep some amount for the film look.

The lens coating does not change the color of the light which pass trough it, but it can change the color of the reflections due to the colors of chemical elements used to build the coating material. So the lens flares probably will get a specific color. One of the most interesting features of the uncoated Apefoscope is it keeps the reflections with the same color of the source light, so you can get horizontal flares with different colors, for example, a police car can allow red or blue flares depending on the color of the light pulsing on the car. you can see this in the two Apefoscope videos on vimeo that was done with an uncoated version. Also the Apefoscope does not have many glass elements wich would make the uncoated system unusable, it works good.

@apefos

Hey great work. What is the difference between a coated version and the upcoming coated ones?

vicharris

I love you dedication to this sir!

The second unit is for sale on ebay. It was used by me to do tests. It is an uncoated version. From now the final units will be offered to donors first. It is buy it now, so first bid will get it.

Next post I will show the assembled units with coated lenses.

apefos

Today was a outside working day. Got new lenses from the optical lab. Bus and walk here and there to get things to rearrange the office/workshop. Now I got everything I need, just inexpensive things like screws, wires, plugs, pieces of wood... I can keep myself inside work.

I am using the Indiegogo money and the money from first unit selling to build more units, lenses and bodies. Indiegogo project let me get the money just after the donation so I can use it to build units to people who donates there, so I will have some units for the donors from PV and some units for donors from Indiegogo. And after the first sales, a new batch of lenses and bodies will be made, and so on...

From tomorrow I will concentrate in assembling the units with coated lenses and just after it I will shoot / edit / upload videos showing coating test comparisons.

The office/workshop rearranging will restart just after it.

I felt sad when DSLR revolution decreased 35mm adapter sales, now I feel happy working with adapters again! Thanks!

apefos

9 hours work, enough for today. Lenses washed and dry, bodies washed and dry, ready to assemble.

apefos

Today it was 6 hours work until now plus 1 hour for lunch and rest.

I realized if I keep rearranging the office/workshop until the end it will take long time. So I decided to mix the tasks. I finished the project in how will be the final design to the workshop and clean, reinstall, recalibrate the drill machine. Separate just the tools needed to assemble the adapters.

Today I will start assembling 6 adapters with coated and uncoated lenses. It is a careful job. I think I can finish within 2 or 4 days. I need to feel how long I can work each day without get into stress again.

Tomorrow I have a meeting in the optical lab to get more lenses and also to see the three new grinding machines they got. Also get somethings to use in the office rearranging, screws, wood, plugs, wires...

apefos

The back pain made me to keep quiet for some days. Also, after more than two months immersed in almost full time mental work, I was shoot down by a big tiredness. Suddenly I found myself trying to work but could not. I am feeling better now, but moving on not so fast (body and mind) to avoid another break.

Today I realized if I shoot every light situation with each coating version before upload, it will take too long for people see the results. So it seems it will be better I shoot one light situation with one version, upload it, and so on, until I complete all light situations with all versions.

I will leave a mystery about the first unit destiny for now. If the buyer wants to reveal some footage after get it, so everybody will know. About Brasil x China: I can't stop getting ideas about a script!

The coating footage will bring good surprises.

anti12

@apefos, I hope you have completely recovered.

Did the coating improve the flare quality or reduce internal reflections? Please give us some teaser.

As for the manufacturing secrets... I hope you didn't sell your first unit to China ;)

vicharris

I'd say post less for now. Just to play it safe. :)

apefos

As I promised here they are, the new black plastic bodies:

I just need a few days to finish rearranging the office/workshop. I started last week but I could not go on last days due to the back pain. Now I am feeling better and after all tools are in correct place I will assemble the adapters with the coated lenses and shoot the new video.

What I can say for now is: I looked through the new coated lenses and I liked what I saw!

apefos

First Apefoscope shipped today, It was a few days delay since it sold November 29 because I was without bluray discs in stock to burn the two videos. I went downtown yesterday and got the blank disc and now it is shipped!

The medicine pills are helping, I can walk and sit at the desktop!

Next post I will show the new plastic bodies.

Now that Apefoscope is turning into a product I need to say I started to feel a little uncomfortable due to showing lots of details about the adapter. In the beginning it was more like a diy challenge, now it is turning into a commercial activity. Maybe it is time to keep some manufacturing secrets? I don't know... just following some intuition...

jpbturbo

I already have my inlaws staying at the house so I've got no room to kidnap you.

Not even the name of the software?

vicharris

Looking good!

apefos

Everything is working as expected. I got the coated lenses from the coating service today. Talking to them I found they have another option, it is the same color of multicoated but I think it deserves a try, maybe it has another intensity, so Monday I will take a set of lenses to do this option I found. There is a photo showing the coated lenses inside the protective box in this post, please hold on the curiosity, I will show all the differences and features in the new video.

I will get the new bodies in Monday from the plastic service and will show a photo.

Thanks again for the donations. You are making it happens!

Edit post: The back pain is under control, I got a doctor meeting and he prescribed me an injection and some pills. Not fully healed yet but I can work.

apefos

Doing an analyses, you said you like The Smiths, but you are not a shy guy because you do not mind doing such question. Best answer is point you to number 17 in my previous post and hide from your attempt to kidnap me!

jpbturbo

I like The Smiths.

Do you mind if I ask what software it was that you found to do optical modeling?

apefos

Why Adriano Apefos does not show his face?

1 - he is a beautiful, handsome, nice/good-looking, fetching, pretty guy but he is married and his wife feels jealous and prohibits him to show himself in the social network

2 - he is so ugly so he feels uncomfortable showing himself

3 - he is a shy guy who likes The Smiths songs and Biquini Cavadao songs

4 - he does not have a face

5 - his face is pink

6 - he is bald / hairless

7 - his face is showing lots of tiredness due to lots of work in the adapter project

8 - he is a fanboy of the "Headless Mule", a famous character in Brazilian folklore

8 - he is afraid of urban violence

9 - Apefoscope is a scam and he will run away with our money

10 - he is an honest and hardworking guy but he think his work says for itself and to show or not to show the face makes no difference

11 - he is hiding himself to raise people curiosity and in the correct moment he will shoot himself, upload to vimeo and charge a small amount in vimeo pay to view service to raise more funds to the project.

12 - he just want to work making good adapters, not searching for fans

13 - he is a craft worker, not an actor or model

14 - he has a trauma due to have suffered bullying in school

15 - he is diy addicted and has a nerd behavior similar to the hacker behavior

16 - he also like pink things, so every suppositions to VK behavior in the previous post applies to himself also

17 - he is afraid the other manufacturers kidnap him to rob Apefoscope tecnical specifications

18 - his head is a super computer, something like an android / robot and this is the reason he developed the Apefoscope so fast.

19 - Other reason you have, please elaborate.

20 - LOLing...

"Apefoscope Anamorphic Adapter - First Assembled Unit" (including the original hand made draw) sold on ebay for 360 usd, 10 days auction, start price 360 usd, one single bid at about one minute to the end of auction, can't say who bought, it was a private listing. Lenses inside the unit is the same used to do the night shots with flares in the first two videos uploaded to Vimeo. A collectible unit. Thank you all.

apefos

In some topics VK says he likes pink Cameras, and also show some sadness when a new model is not available in pink:

From other topics: "Sorry... no pink!", "No proper pink model for VK.", "It can't be pro model if they don't make it pink.", "And pink?", "You know... they have no plan whatsoever to make a pink body for real men who wanna possess a decent mirrorless.", "For me the most important thing is having the GH3 of the right color: pink of course", "Yes. If Panasonic won't make camera in my favorite color it'll be inexcusable.",

Please vote about VK reasons to like pink cameras (one or more options):

1 - Does he want to get attention from girls in the streets?

2 - Is he excentric?

3 - Is he fashion?

4 - Is he metrosexual?

5 - Is he gay, bissexual or emocore?

6 - Is he just kidding / joking about camera colors?

7 - Is this just his sarcasm about the nonsense big companies strategies to get more market share?

8 - Is this just his natural sense of humor which is good to make PV more fun btw?

9 - Is this a sexist machoman behavior disregarding the preferences of sweet and romantic women?

10 - Is he a fanboy of the evil and bastard Pink Panther animated cartoon?

11 - Is it because pink cameras are difficult to sell second hand?

12 - Is this a hacker nerd behavior who likes toy teenager things?

13 - Do you have another explanation / reason? (please elaborate)

14 - pussy is pink

15 - Is it because he like strawberry ice cream?

16 - This is not our business.

17 - Just ban apefos from PV!

18 - Can't stop LOLing!

PS: I will try to do pink flares in the coating tests, tribute to VK!

I must say I got a bit sick by having lifted some weights for arranging the office/workshop. I had to load an iron table and a drill bench and finished with back pain. Now I'm going to rest for a few days to heal the back pain. I'm lying on the sofa and enjoying the time to study the lens software.

apefos

While I wait the bodies from plastic service and the lenses from coating service I am learning how to use a lens software. Everything I did with optics since the 35mm adapter until now was done with math calculations and attempt/error grinding lenses. I learned very much about light behavior, lenses curves and glass properties versus aberrations from this experimental process era. I think the lens software together with my real world know how will help me to predict things easier than just math calculations before spend money grinding lenses. I did a research to find a user friendly and inexpensive software and downloaded a trial version to learn. I am reading the tutorials, documentation and help files applying the lessons in the trial software. If I find this software is good enough for me I can buy it for just 69 usd or if it is not enough I can try another. Many thanks to @Ralph_B who pointed me to a fantastic optics website where I found the software options, and to @JohnBarlow who made me understand the basic principles of lens software and showed me the importance of a lens software to predict things.

@arknox

I like your words, cheers!

Here in Brasil we have a popular expression that says: "De boa intenção o inferno está cheio." which means: The hell is full of good efforts and good intentions. This means which really matters is if you can do, not the efforts you did to try. So after all the previous development and improvements, and after the coating tests, when I will realize the Apefoscope is a product, I will consider the project succesful.

I need to say it will not be an industrial product with the same finishing found in big companies products, it will be an improved diy product. A good quality product which looks like workmanship, handycraft, craftwork, artisanal, artisanry work.

@fatpig

The reports I did here about donation was from donation I got through my website: 503,93 usd after removing paypal fees (20 donations in different amount each)

The Indiegogo until now is 105 usd (gross amount without removing fees).

The extra amount after pay coating tests will be used to build units to sell

@sebasp1

I can ship to my hermanos!

To be honest I consider you won the last game: 2x1, because as we say here: penalty is lottery. Our coach Mano Menezes was fired after that game. But we are the champions!

sebasp1

wow i haven't been on PV for a while and when i come back i see this! apefos you are a genius! and a very kind sir. thanks to you i could adapt my 3.5mm C lens to use with my gh2 and now you are doing a great job creating this adapter thank you so much you are going to make my dream of filming in anamorphic come true. Keep the good job and i hope to donate soon. also i hope you can ship to argentina :D!

Howdy, Stranger!
