Originally posted by Boris_Akunin 've had the ee-S in my sights since I put a manual prime on my K-5 for the first time but I've always had a number of slow lenses. Now however all my lenses (apart from two stopgap lenses that will be replaced soon) are f/2.8 or faster, so it's time for a better focusing screen. I may still get the DA21/3.2 at some point but the only lens on my wishlist that's really slow is the Sigma 8-16/4.5-5.6.
My situation is very similar! From what Iīve been able to learn, The EE screen seems to be a better option because itīs cheaper, doesnīt mess with metering, allows to focus anywhere, not only the center.
About the EE-S screen:
Renders "real" DoF from f/1.4 onwards vs f/2.8 for the K-5 stock screen.
Starts getting dark after f/4. This shows much when light is bright and our eyes get used to it. If light isnīt too brigt you wonīt notice that much difference when looking though the VF.
VF darkens fast as you mount lenses with f/4.5 - f/5.6 maximum aperture.
My fastest lenses are f/2.8, except for the F50/1.7 so my main question is if I will see a benefit from the EE-S screen over the stock screen.
