You mean the 100-500 RF lens right?

Depending on how much fungus is there on the lens, different techniques are used to remove it during cleaning. You need to understand that to access the interior of the lens, it is disassembled into its individual components, such as the front and rear elements, the aperture assembly, and the focusing helical. So it’s a delicate and serious process.

Also, if the issue is severe, ultrasonic cleaning is done which may remove some of the lens coatings, as the high-frequency sound waves can agitate the cleaning solution and cause it to penetrate the lens surface. And this may impact image quality.

So to cut the long story short, avoid it 😉

Varsha, To know the answer it is very important that you fully understand the concept of depth of field and also lens MTF charactersistics. I have a separate chapter for Dof and in “camera lens buying guide” I talk about MTF of a lens. Please go through them.

And in short, using an aperture value depends on the focal length of the lens being used, as more than the aperture, it’s the focal length and the camera-subject distance which matter in landscape photography. So using f8 or f11 or f22 depends on the above 2 parameters.

Good point. Let me update the document and share it.

Sandeep, It depends on a lot of factors and not easy to provide the exact settings. You need to have a good understanding of exposure triangle parameters and metering. Why do you say that portrait is impossible?

This option is not available in the platform currently. As an admin, I can pin a post/topic. But based on the queries coming, I can include the key things in the FAQ.

Please note that I moved this discussion to “Everything Photography” section.

The fundamental understanding of exposure and metering is missing. You need to go through the below courses to get your concepts strong:

4. Exposure Triangle – Shutter Speed, Aperture and ISO

If it’s not an issue to carry that lens, then I would definitely recommend it.

[Sudhir Shivaram]

You will know the sweet spot of the lens if you see it’s MTF chart.

[Sudhir Shivaram]

Oh yes , that’s right. I missed the part of using external flash where you can make creative exposures.

[Sudhir Shivaram]

Well, looks like you go it.

[Sudhir Shivaram]

oh well, if the light is really harsh, then it’s impossible to get it ????

[Sudhir Shivaram]

Oh for that you really need to understand exposure and metering which is part of my course. Especially metering since in challenging light situations like this, metering is what controls everything.

Do go through the exposure triangle and metering course in Basics and Advanced concepts of photography course.
