I had a few minutes to try out something I had been considering for all of ... well, five whole minutes. It's like that, sometimes. Inspiration and asking, "what if ...?"
One of the big complaints everyone usually has was the amount of shake you get when you use long glass. Without stabilization, you should probably subscribe to the "reciprocal method", where you take the focal length and invert it for your shutter speed.
So, in this rather extreme case of a long lens, a 500mm focal length becomes ... yep, 1/500 sec.
Well, I have news for you. If you can get 1/500-of-a-second coupled with a base aperture of f/6.3 to produce much indoors ... you are quite photographer. Heck, you cannot even sync a flash to that kind of speed. Hand-holding your camera at that length is a rough go.
So, here we introduce SONY's Super SteadyShot. What does it do for you?
In short, SSS reclaims shutter speed. Obviously, if you are pretty steady, yourself, you can get a lot more out of it.
Through a couple quick low-light situational shots (single 40W fluorescent bulb) ... I was able to use the α700's ISO-6400 capability, coupled with a 1/5 second exposure (handheld & SSS-assisted, of course) to try and effectively reproduce a flash shot of 1/60th sec ISO-400 with a reasonable degree of consistency. Now, admittedly, this is the ""RAGGED EDGE" and you cannot expect precision results. This is a desperation move, because someone did not provide enough light for the camera to 'see' much.
So, what does this mean? Well, given some pretty lousy lighting/exposure situations ... the α700 can still dig you out a "reasonable shot." 500mm @ f/6.3 is dark by almost any standard. Yet, even handheld ...

EXIF: 500mm - f/6.3 - 1/5 sec. - ISO-6400 - Spot Metering - Center-weighted Focus - Fluorescent Lighting (40W)
Add the flash:
44749
EXIF: 500mm - f/6.3 - 1/60 sec. - ISO-400 - Spot Metering - Center-weighted Focus - Pop-up Flash (TTL)
(the above images are JPGs and only resized to fit on this webpage ... and are as-is with absolutely no post-processing performed.)
To truly appreciate this, you really need to try it with a Canon or a Nikon camera. Don't forget to dig real deep for the $6500 it is going to cost for the IS-equipped 500mm f/4 lens. SONY's Super SteadyShot comes along for the ride for free.
If the SONY α700 can pull off this kind of miracle w/o a high performance lens ... just think of what it can do for your own photography with the lighter stuff. I know, I do. :p
