For every other Canon DSLR camera like the 7D, 5D Mark II, 60D, and 5D Mark III you'll need a totally different grip. One good thing about the Rebel series cameras is that they continue to share the same LP-E8 battery type along with the same BG-E8 Battery Grip. A cheap BG-E8 grip for the T2i, T3i, and T4i with decent reviews can be found on Amazon and comes with two extra batteries (Click Here).
Ok, so I have the new Canon EOS T4i, and what always bugs me about these LP-E8 chargers is the long cord that's messy to pack up. A while back Kay shared this tip with the Canon T2i chargers, and it still applies to the Canon T3i and Canon T4i. If you had just a few of these chargers, you can see how messy those long cords would be on a single power strip. This little tip keeps things easy and neat, and easy to pack up. These plug adapters for Apple chargers can be found for about $3 bucks + Free Prime Shipping (Click Here).
If you're trying to prevent glare on the screen, you could use an LCD viewfinder. Of course it makes it harder to see the screen from certain angles without having your eye placed directly into the Loupe. In these situations, maybe a simple sunshade or LCD hood would be a better choice.
I've seen the folding plastic pop up sunshades for mini LCD screens, but I haven't seen anything quite like these Vello Mini LCD Hood Sunshades. Looks like it just folds over the flip out LCD on your camcorder or DSLR (with swivel screen) such as the Canon 60D, T3i, GH2, or even the new T4i. Available in 2.7", 3.0", and 3.5" inch LCD screens via B&H (Click Here).

For those that just might be thinking about buying a Canon 60D in the next few days, don't forget to look into those rebates. You could get a Canon 60D (body only) for about $899, or you could get a Canon 60D (body) + Canon Pixma Pro9000 printer for just $898. There's plenty of other DSLR body rebates going on this month so make sure you look through them before just jumping in to a buy. Most of these offers expire at the end of the month. [Thanks Brennan]
A Canon T3 (not T3i) bundle shows up on the eBay deals page. Not very exciting since the bundle is based around a cheaper camera strap, SDHC card, camera bag, card case, card reader, lens cleaning kit, and mini tripod. Surprisingly though, they sold over 70 units, several dozen today. You can check out other discounted camera deals over at the page (click here)
What can I say? It's simple, it works. As you can see it works on the GH2 perfectly without losing view of the entire LCD. Of course it works on the T3i and 60D. The velcro design and stretchy neoprene means it's adjustable to fit a variety of different cameras or even a variety of different view finders. I'm not sure about applying pressure onto the LCD while it's swiveled outwards, but for anyone that has worked outdoors in bright daylight, it's a good way to keep the function of the swivel LCD while acting as a sunshade / VF. $10 dollar tool that folds flat taking up no extra space in the bag. Heck why not. Found via Amazon (Click here)
Varavon's latest product is a flip up style ViewFinder called the EX-Solo with models available for all the popular Nikon, Canon 5D / 7D / T2i / 60D, and even small Panasonic GH2 cameras. The ViewFinder attaches using the Tripod base adapter (no sticky frame here), and still provides an access port if you want to mount a quick release. The EX-Solo includes a diopter for those with less than perfect vision and flips up a full 180 degrees when the VF is not in use. The view finder stays put with a few magnets when it's in the closed position. Varavon pricing has always been a bit high, but quality has been top notch in it's other product line. At least it's still cheaper than the high end viewfinders. Looks like they are just getting in stock (click here).
