: one? B&H was selling them for around $4,500 in 1999. And the RD-3000 Vectris-based system never had a chance). See Magnus. huh? Or is it Bill Tuthill who has the RD-175 (Sorry: I snipped that little bit!) yeah, OK, no, that's me. But I don't know what to comment :-) |

The low-light photographer will still run out of usable shutter speeds long before he runs out of autofocusing capability. What lenses are you using in low light? In the case I just tried then, it was Minolta's cheapo 28-100/3.5-5.6 that comes with the Maxxum 5 kit, and ISO 400. I suppose I should put on a 50/1.7 and try again at some higher film speed. Okay. Just tried that in my windowless kitchen with the lights out, a little light coming in from the living room (there's no door there). With the 50/1.7 in place and ISO set to 800 (which is faster than any film I generally use), by pointing at the darker areas of the kitchen I can get the shutter speed down to 1/8, wide open of course, and it still autofocuses rapidly--virtually instantaneously in fact--and positively. I don't see how an AF illuminator could do any better than that. Quite easilly. When it can't focus w/o the illumintaor, the illuminator will come on and the lens should focus (and that's the point). That's the fastest lens I own. I also have a Sigma 28/1.8 but that should be about the same, the AF still working at light levels lower than I'd ever hand hold. Of course I never really shoot sans flash in light that low anyway. In fact even WITH flash I rarely do. Tripod, cable release and away you go... _much_ lower. Sure, but what I'm saying is that I just never have any need or desire to do that. If I did, and the camera couldn't autofocus (which would have to be awfully, awfully dark) I'd just use a small flashlight as an AF illuminator. Certainly not much additional bother if I were already setting up a tripod and plugging in a remote control. N. |
