Coating isn't that magic, it helps a lot, mainly for internal reflections on the element's surfaces, but it can't 'hit a way' the sun's rays hitting the lens's surface, which is indeed unfortunate...

Philippe-Georges,
Interesting library!!
Interesting library!!
I didn't know they did that, wow
Till a certain extend it is the same 'technique' as in a gooseneck for on a microphone stand...
I clearly need to find an other place in the house where the light is as good for snapping a few fast photo's with the smartphone!
Or perhaps hang a sheet in front of the books...
Not at all! I like the books.
Me too. Instead of a sheet to hide the books I’d prefer that the camera be moved out of the frame so we can see the books better!
Will this do?
PS: perhaps, instead of 'show your camera', a new thread on 'show your books'?
He might have decided that in the given situation a hood wasn't necessary?
If the sun is not in the image you want, holding the dark slide (or hat, or whatever) in a position where the shadow it casts just barely covers the front lens element and no more will ensure that you don't get an edge of the slide in the image area.
The best solution is a compendium that you can rack in and out to just past the point where it vignettes, but there's not a really good compendium that I've found for working in the field. They're big and bulky.
The best compromise I've found is an old Voss filter holder with barn doors. Search eBay for Voss filter holder and you'll turn up a few. They only have two doors, but they fit lenses with filter sizes up to 67mm, are lightweight and can hold a gel or resin filter too.
The same caveat applies about positioning the doors so that you don't vignette

The Voss can also be used with 67mm screw-in filters. Get a 72mm to 67 mm step-down ring. The 72 mm thread will fit securely on the Voss gelatin filter holder insert and allow you to use modern filters along with the lens shading function. Cheap and works surprisingly well.
I've had fewer problems with a held dark slide than any other kind of shade. It's fast and easy - no need to buy anything else unless you really have a need for something "special" that will slow down the process and may introduce its own problems. (Gear-junkies vs. photographers.)
How do you avoid inadvertent vignetting?
If the sun isn't in the photo, then just barely shade the lens front element and keep the shade level/parallel with the top of the frame. If the sun is in the frame, then don't use a shade at all because a shade won't do anything anyway. It's not rocket science.
Inspired by some photography masters using their hat or a dark slide to shade the lens from the sun, I did some primitive and basic DIY...
My memory is a bit 'shaded', but somewhere I saw a simple system to flag the lens from disturbing light, it must be on a cinema set I think.
Anyway, I made something that looked useful to me, out of 100% recycled material: a gooseneck from a old desk lamp (about 25 cm long), the cold shoe mount of a broken smartphone holder, a 1/4" screw I found in a box, a piece of black painted aluminium plate, a left over of tube industrial glue, some black shrink insulator tube and what was left of my phantasy...
By this, I can see on the GG when that 'thing' is blocking the view, particularly when an extreme shift is applied, and my hands are free...
PS: the wide angle of the iPhone deforms the view and the gooseneck seems longer and the pannel larger than they really are...

Second this.
Here all mentioned set up with Anba Ikeda & Goerz Dagor ~ 150/6.8 & 67mm filter
I was using dark slide as third barn door.

I have used the Cokin hoods in the past. But really like the now-discontinued Hoya multi- angle hoods because they are compact when carrying in the field. You have to be careful to work out in advance what will work with a given lens and what won't.
I found to my regret that the 52mm Hoya multi-angle hood vignettes with a 135mm lens (on 4x5) except at it's widest position. No problem with a 67mm Hoya multi-angle hood though.
I bought a compendium shade but it was too small for my largest lens. I went to a movie style Matte Box with a large barn door on top. I only had to buy 1 adapter ring. The 4 included rings covered my other lenses. SmallRig Lightweight Carbon Fiber Matte Box

adding a 72-67mm step-down ring to the Voss allows you to use 67mm glass filters. The 72mm thread can be used to attach the Voss and the step-down ring to each other. This works more than well-enough and does not affect either the Voss or the filter or rino.

My Voss holder (two barn doors and a spring clip that expands to go over the lens and then pinches it to attach) goes on over lenses that accept 67mm filters just fine, both with and without filters attached to the lens.
