i really like the 16:16 step for trying to improve contrast.
Sometimes we need a little help from tools! I have feared having to try heavy force like you have. Best regards.
Every person says to use a different type of grease for the helicoid. I'm confused which one I should buy
Good question. The correct answer is - the one used by the manufacturer. But today, there are many different lubricants, so you can see a lot of variety. The lubricant must have certain properties: not spread, retain its properties for a long time, and so on.
Виталий, я купил такую линзу на ebay. Все ок только кольцо диафрагмы показывает наоборот. То Есть если линза полностью закрыта на кольце показывает 2 а полностью открыто 16. Как это починить?
Это значить, что объектив был неправильно собран.
Необходимо разобрать и собрать правильно. У меня была подобная проблема, но с другим объективом, вот ссылка на видео th-cam.com/video/ADHV3f_-FRw/w-d-xo.html
Does the contrast mod actually improve contrast in pictures?
The theory says it should
Did you have a before and after this trick on the lens? 🤔
Yes, of course.
@@xVoLAnD can you post something?I'm curious to know how improves, just to know if worth to do this modification 😃
@@FrankP83 Your request has me stumped. I have no idea how to compare. If you look at other disassembled lenses, you will see that there is something like rubber on the edges of the lenses.
Also, you can find information on what is this and what for. That was my idea.
You can suggest how I can do that?
@@xVoLAnD I think he was thinking marker on edge edges trick, before images shot without marker applied and after with marker on the edges?
@@muris60 I understand. By eye - it got better, but it's better to have a scientific approach to measure 🤷🏻♂️
what is the tool used to remove the front lens? link? name?
This is a metal Vernier Caliper s.click.aliexpress.com/e/_DBBBgHx

Или пох ни какой разницы в результате чернения? Обьективно а не из категории "мне кажеться"...?
