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).

This is not a review of any sorts, but just my impression on the Canon G1X point and shoot. I wanted to see what Canon had come up with in this new G series camera, so I decided to take it around the Pier 39 area in San Francisco. I attempted to give the footage a vintage feel of Old San Francisco so I tried using a few Cinegrain film scans, boosted saturation, and added more contrast. I also cooled down the shadows and warmed up the highlights. I don't know if anyone really cares, but if you want to see the original footage, let me know.
I tested a variety of different scenes with the G1X and found plenty of aliasing and moire in video mode. The G1X probably serves better as a stills camera. The still images coming out of this camera are very sharp and has decent dynamic range in just JPEG. I haven't tried shooting RAW with the camera.
The G1X does not have full manual controls for video to adjust shutter speed or aperture, but you do have the option to lock the exposure before hitting the record button. Once you lock the exposure, you can adjust exposure compensation if you're trying to bring back some shadows or pull down some of the highlights in your scenery. The G1X also has a built in ND filter which helps slow down that fast shutter speed look on bright days. For HD you only get 1080@24fps or 720@30fps. Even though it lacked 60 frames, there's a flag clip in the video where I slowed it down 50% and it didn't look too bad.
The swivel LCD of course makes it so easy to frame a shot up high or down low. The boot up time is very quick, so I never felt like I was missing a shot when the camera was powered off completely. For a point and shoot camera, I was hoping it would have more zoom. Consider the extended digital zoom feature for video worthless. For wide angle in crowded San Francisco, there were plenty of times I felt like I wasn't getting a wide enough shot. Canon decided against making a mirrorless camera, or even joining the micro four thirds party. Instead they designed this G1X with a larger and better sensor than most other point and shoot cameras. It might do well in some areas, but the aliasing and moire is terrible for video. I really wanted to like this camera, and gave it my best shot, but the price and lack of features don't really add up here. For a cheaper price, I think you'd be better off with something like a Sony NEX5n.
More specs available for view about Canon's latest G1X camera. With a sensor almost as large as the Canon 7D and ISO noise rumored to be better using the latest High-Sensitivity CMOS sensor with DIGIC 5 Image Processor (up to 128oo ISO), this will be an interesting camera when you don't want to carry an interchangeable lens camera or something as stripped down as a pocketable point and shoot.
58mm filter thread available on the lens, optional lens extensions can be mounted (i.e. wide angle), hot shoe to accept external Canon Speedlites, and a waterproof housing will be available also for some underwater action. I was pretty impressed with the video quality on the pocketable S100 with Digic 5 processor, but the S100 does not have an imaging sensor as large as the G1X. I can't wait to start seeing some samples. You can check out the long list of features on the recently available Amazon pre-order page (click here).
