Low light autofocus

[pikey]

This is an understanding point more than anything.

My previous camera, a prosumer Sony DSC F7171, used a laser matrix to set the focus in low light situations. It was unobtrusive, accurate and looked really cool.

My replacement camera, a DLSR Sony a100, uses the onboard flash to set the focus in low light conditions. You have to manually lift the flash and then it strobes about 3 times - this is even if you turn the flash off. It's clunky, slow, and blinds the hell out of people.

So, my question is... why? Surely the new camera being 5 years newer is better, but I can't help thinking that they've taken a step back.

What's a flash?

(Anything for an easy life... I just tell people to stand still)

I know, I should stay in more.

I hate cameras that use bursts of flash for AF assitance. The way to avoid it is to use an AF assist beam of an external flash.

Might be because the a100 is actually a Minolta and Sony haven't gotten around to adding all their compact camera Technology. I have an old Sony DSC V1 and it really is great for a compact.

Possibly. The Dynax I used to use had a great AF assist beam (separate from the flash).

EDIT: Having said that, my Canon doesn't have one either! I use a wireless transmitter (ST-E2) or flash gun if I needed the assist beam.

My Canon 300D does that.

Right by the barriers at Le Mans at midnight on Thursday.
