Focusing Screen? Ee-S vs Ee-A vs Nikon D?

[likwidplastik]

I'm about to purchase everything for my DIY adapter. My last concern is the focusing screen. Which screen works the best?

I've noticed that most people are using the Canon Ee-S or the Ee-A. Which one is better?

I like the Nikon D screen bacause it is a "snap-in" type, meaning less glueing will be involved. I haven't seen many people using this screen though. Is it inferior to the Canon types?

Looks like no one has purchased all the 3 focusing screen and compare them to one another. I'm also interested in knowing which one is better if I have a chance to get another one.
I'm using Ee-S on my adapter only because it's available at the time I ordered all my materials. I think I would have bought the Ee-A if given a choice.


Edit: Finally, here is the test.

I'd love to see a comparison between the Ee-S and the Ee-A :)
I'm using the Ee-S, but there's a lot of light loss unfortunately. I know the Ee-A is supposed to be (a lot) brighter, but some sample footage would be nice... (I've read that the bokeh on the Ee-S is better btw)

Well maybe I'll just order an Ee-A as well on ebay. My Ee-S is glued with a silicon compound, so it should be easy to remove it from the GG without damaging it :)

Edit: Here's (http://photo.net/bboard/q-and-a-fetch-msg?msg_id=00GrRY) a nice chart of light loss between Ee-S and Ee-A. Doesn't look like it's that much, but sample footage would still be nice!

I think this is a great thread, cant wait to see some comparisons.

Is the fresnel different between the Ee-S and Ee-A? And which one is better at reducing vignetting?

I've read that the EE-S shows more convincing bokeh than the EE-A, is that correct?

I'm building an adapter with an EE-A focusing screen. The reason for why the EE-S was built was to facilitate an easier means of focusing with macro photography. It creates a steeper parabola of focus for the object so the change in focus is very great, hence noticeable, as you turn the focus ring. I'm not sure what other effects the screen has on the image, but that was the reason it was manufactured. Since I wanted to maximize light input, I chose the EE-A screen. I'll post some demo video, when I'm done with the adapter later this week.
