Diane and Bill,
I got everything today:
Markins P26U Universal Quick-Release Plate -- it may not be an L-bracket, but it's as great as it gets at the moment. Very small, adjustable enough that you can fix it so that the battery door opens without having to remove it (while still remaining centered on the lens barrel), and the logo is small and now hidden underneath to the side.
Sigma VF-21: It's a jewel... very tiny and quite beautiful and the frame lines are very bright and quite accurate at first glance (and why wouldn't they be; it was designed for the camera). As I said, I'll do some testing over the weekend.
Extra Battery: bringing my total to four. I had planned on having five but after paying for everything else, and realizing that the VF-21 may cause me to turn off the LCD occasionally, I settled for four for the moment (the batteries really do run down quickly).
46mm Hoya UV Filter: I had been testing an old 49mm from my Canon G1/G2 with a step-up ring and like it... so I bought the right size, plus two lens caps.
Vikuiti ARMR200 Screen Protector from 3M: Went on well, even with me doing the affixing, and is a matte finish. Looks good and feels good.
Lens Hood and Adapter: I didn't need the extra lens hood, but I did want the adapter to screw onto my macro filter so I can just bayonet it on, rather than having to remove my 46mm UV filter and screw on the 46-49mm step-up ring plus macro filter.
All of the this caused me to break out the table-top tripod and the monopod this evening just for the pleasure of snapping my new Markins plate to my old Markins ballhead (on the tripod) and Markins QR clamp (on the monopod). Very nice... I was getting tired of screwing the camera on and off a normal ballhead.
And that's it for the moment, except to say good night. Testing of everything in the next few days. Sorry for the wait. Weather is still grim, by the way.
Don
