I was browsing through some of the snapshots I took a few weekends ago at a Mother's Finest Concert and found some at pretty slow shutter speeds, while I was bracketing shots of the scenary while walking around before the concert.

Hmmm... I wonder if maybe blur from mirror slap isn't as much of an issue at a slower 1/3 to 1/2 second, since the mirror vibration is a lower percentage of total.

Or, should I try mirror lockup with hand held photos, too? lol

Konica Minolta Maxxum 5D, ISO 1600, Vivitar 70-210mm f/2.8-4 at 70mm, one stop down from wide open at f/4, hand held at 1/2.5 second according to Irfanview (rounds toa faster1/3 secondusing IExif). Cropped and Downsized using Irfanview. EXIF in image.

It's sharper than you'd expect for shutter speeds that slow.

Anti-Shake was on of course. :-)

I used faster shutter speeds for most of them though. This one was hand held at ISO 3200, 1/13 Second, 70mm and f/4.

Given that 70mm gives you the same angle of view you'd have with a 35mm camera using a 105mm lens, I'd say the Anti-Shake is working well. :-)

One more.

This was exposed about 1/3 stop darker than this and brightened using the Gamma Slider in Irfanview (making it equivalent to approximately ISO 4000).

KM 5D, Vivitar 70-210mm f/2.8-4 at 85mm, f/4.5, ISO 3200, hand held at 1/13 second.

Since this has the roughly same angle of view as a 127mm lens on a 35mm camera (85mm x 1.5 = 127.5mm), this is being taken at about 1/10 the rule of thumb for a hand held camera (and the subjects aren't even stationary). :-)

at that speed my hand would be shaking all over the place

I've used AS even when the warning light tells me not to and still had good results. I doubt that I am much steadier than anyone else on average so maybe the warning light has a little cushion built in or mine is just more sensitive. Of course that only applys to situations where I am using a borderline shutter speed.

It also shows yet again that iso3200 is better than a GOOD compact cam at iso400/800.

Bright lens, A/S, and iso3200 make things happen that should be impossible. Blurred people shots (from subject movement) can be really interesting, and can be grabbed at any time without needing a tripod.

Press your drive mode button (just behind the shutter button) and select the 2 second self timer.

You'll see the mirror flip up and lock when you press the shutter button, then the shutter will open and close at the end of the 2 second timer. KM tied mirror lockup to the self timer feature.
