Had a bit of a scare last night. I went to charge my batteries for my 7DII but decided to check the current charge on them since I hadn't used it for a couple of weeks and forgot if I had them charged since then. Flipped the switch and it wouldn't power up. Figured the batteries in my grip were dead so I charged them then tossed them back in. Flipped the switch... dead. Had a mini heart attack and began trying everything in my power to fire it up. Took off the battery grip, tossed a battery directly in the body... still dead. I started to look into finally using my CPS gold membership to have it fixed before I head out of town next weekend, stewing because I wanted to use my strobes this weekend and this is the only body that I can use with my Pocketwizards. I eventually realized that I didn't have the battery door on (hahaha) so I pulled it off of the battery grip, put it back on the body and voila, it fired up. I then inspected the battery grip to try to figure out why it wouldn't read and noticed that this little tiny tab that sticks up and slides into the battery door hole on the body was missing. I was planning on shooting tomorrow so I hopped on amazon in search of a replacement that I was hoping would show up this weekend. What do I see when I sign in? A nicer Meike battery grip with free one day shipping to prime members if I ordered within 6 minutes. Ended up getting it figured out from beginning to end within 45 minutes. Good times!
