Eg-S or Eg-D screen ?

So here is question, which one do I get. I have 2 lens under 2.8 and 2 at 4. I want both benifits, manual focus and grid. Would you get the s and just worry about horizons in pp if needed?

I use grid screens in all my cameras. Have for years, whenever they were available. It just helps me compose better without giving it a lot of extra thought or concern... I still have to fine tune horizons and verticals, just not as much.

With the Canon screens, the grids also give you "rule of thirds" guides, which you can use or not use as you see fit of course.

In 5DII, it's ever so slightly dimmer than the standard screen. Not really noticeable after using the camera for a while. Don't forget to set the custom function, or your metering will be slightly off.

If I need to do high precision focus, I just use an angle finder with it's two levels of magnification. Live View zoomed in works pretty well, too, but the LCD screen isn't always viewable due to ambient light. .

I got the Eg-S a week ago. It is fantastic for shooting wider than f/4, but I find it too dark to use with f/4 lenses indoors.

I would also like a grid, but between the grid and the focus accuracy I'd pick the accuracy. You can rotate the image afterwards without losing too much, but there's little you can do if you miss critical focus.

See exactly my dilemma, both posts are why I want both. Has anyone gotten one and switched for the other?

You could buy both, and swap them out as needed
