The Sony A55's pellicle mirror is mostly transparent, and only partially reflective. I can get 4,000 shots on a charge of a Nikon D7000, since real SLRs don't need their LCDs at all to shoot, but this Sony will be sucking you dry for power very quickly. I sucked-down a large amount of charge in just a few hours of playing. The A55 is not the camera to buy if you're concerned about conserving electricity.

While Nikons and Canons work all day, or all month, on a single charge because you're viewing the optical image for free using natural light, the A55 always needs to have its LCD lit and all its internal signal processing active just to look though the lens. The penalty for all this electronic fun is that the A55 is a battery-sucker. One weirdness is that immediate Image Review hijacks the viewfinder, but if you want Image Review, it pops up in your viewfinder after each shot.

The A55 has eye-control, meaning that the rear LCD and viewfinder LCDs switch on and off automatically as you hold the camera to your eye, or hold it at arm's length. Playback? You can play back with your eye on the finder, and zoom, too! There is a 2-axis virtual horizon which can be superimposed over the viewfinder image. If the lighting is dark, no problem the camera boosts its sensitivity, and that's what you see through your viewfinder. Since the finder is an LCD, you can see and focus in the dark just as well as in daylight. If you think I'm kidding, try your depth-of-field preview button and you won't see any difference between f/1.4 and f/2.5 on a real SLR today. Real SLR focus screens were redesigned in the 1980s to give more brightness with slow zoom lenses, but lost the ability to show the much narrower field with fast lenses. With fast lenses, like Minolta's 50mm f/1.7 MAXXUM AF, you can see the real depth of field, unlike with real SLRs. You can set anything without taking your eye from the finder.ДЄs you're shooting, you're already seeing the effects of light, color, saturation and contrast settings as the camera will see them, before you take the picture! Since we're viewing an LCD, all menus come up in the finder as you set them. Now that Sony has perfected the EVF camera, there are numerous advantages. The Sony A55 brings the future to us today because it's the first EVF camera I've seen that has a viewfinder with little enough image delay to make it useful for action, it has enough resolution to see focus, and because it uses a half-silvered mirror to divert the live, 3-D optical image to a real-time AF system, the A55 autofocuses as fast as a real SLR.

Worse still, all previous EVF cameras had to focus using the delayed, 2-dimensional image from the sensor, making autofocus way too s-l-o-w for action. Likewise, previous EVF cameras had LCD finders with resolution too low to see focus. Previous EVF cameras had finders that were delayed by a fraction of a second due to internal processing time, making them useless for sports or action. With electronic cameras, we can see the image as seen by the sensor in close to real time electronically. With film, we had no other way to see the image before it was developed, so direct optical viewing with a reflex mirror was needed to see and shoot through the lens quickly. The Sony A55 represents the future because the flipping mirrors of SLRs were only needed with film. The mirror flips out of the way for each shot to expose the film, or the sensor in a DSLR (digital SLR). In a real SLR, a mirror is used to view through-the-lens optically on a ground-glass screen to focus and compose. This allows the A55 to have the same fast autofocus as a real SLR, while everything you see through the viewfinder is coming from a tiny internal LCD fed from the image sensor. The A55 uses an additional fixed, half-silvered (pellicle) mirror to allow an optical (phase-detection) autofocus system to view through-the-lens at the same time as the image is hitting the live-view sensor.

The A55 is an electronic viewfinder (EVF) camera, not an SLR. When I say 'A55,' I mean all three models. Otherwise, they all have the same viewfinder, the same features, the same menus, the same firmware and the same users's manual. The A33 is the same thing as the A55, with a few less pixels, and rated only at 7FPS instead of 10FPS. The A55V adds a built-in GPS, just like the iPhone and iPod touch. I'll usually mention the A55, however, the Sony A33, Sony A55 and Sony A55V are the same thing. This new Sony A55 is a taste of the future. Buy from Adorama, Amazon, Ritz, B&H, Calumet and J&R.
