So now having the whole package, grip, winder +prism with 2.4magnifier, "Are you feeling lucky , punk?" is what came to my mind while looking at and holding the camera.
The grip as expected , gives a nice way to hold the beast, but it really twists your wrist with that much weight, so you need support from right hand but then focusing becomes the hardest part while supporting the camera with both hands.
On the plus side, nice side effect of the winder is that the left focus knob gets raised up, so some crude focusing can be done with left thumb. Almost as if by design... The big minus, you can't mount "almost" anything in the hot shoe, hence they add a cold shoe on the grip (at least it looks cold) meaning I'll need a 2nd cable from back to PW. I also got the shorter back to lens cable, so that cable is nicely routed around the top body, and stays out of the way now.
I also found a new/cheap Type C screen with a microprism (no split). It helps out a lot on brighter subjects with magnifier on WLF.
Magnifier on the prism, gives nice bright enlargement, but wearing glasses, it's not ideal to flip up my glasses, then flip down the magnifier.
Going back to prism with with the mirror image correction, is very comforting at the moment, the tunnel is there as some say, but it's not that bad.. I'm still uncomfortable composing with the WLF. Although getting better. So i think i am glad to have gotten it, definitely usable. This is the non-AE, finder 2. Heavy chunk of glass, as is every piece..
