DA Limiteds and Low Light

Currently, I just want to get the four DA Limiteds to satisfy my hunger for prime lenses and my photography needs. [I know that the DA 35/2.8 Macro Limited is not available on the market yet.] I also like the DA Limiteds over the FA Limiteds due to size. Though, my main concern is that they may not do so well for low-light photography. I've heard them called relatively fast lenses. Will I need to use a flash in low-light? Are they really that slow?

Not to hijack your thread but, I'd be interested in knowing how well they perform in AF, in low light. Specifically the da70. I'm not so concerned with speed "apperture" wise as I will be using it stopped down to at least 5.6 and using a flash. More concerned with AF speed and accuracy.

Well, take your 28mm f/2.8 inside in a "low light" situation, put it in Av mode, f/2.8, set the ISO to 1600, and see what kind of shutter speeds you get. In my experience with typical room lights at night (ie no natural light coming in through the windows), f/2.8 is too slow, with shutter speeds around 1/10s. TOO slow for non-static subjects, although you might get lucky once in awhile with the subject(s) remaining fairly still. At least SR helps with camera shake. This is when I put on my 35mm f/2.0 or 50mm f/1.4. With the 50mm wide open, I'd be able to get 1/40s, MUCH better for people sitting around at a party (as long as they're not dancing )

So f/2.8 isn't the "magic bullet" of low-light photography. Do you have a flash? If you want to take GREAT indoor shots, get a flash and bounce it.

EDIT: The 21mm is f/3.2, so a bit slower, and just noticed the 70mm is f/2.4, so a tad faster than f/2.8, but I think my argument still holds, and I recommend you experiment with your 28mm @f/2.8 to see what kind of shutter speeds you'd get in "low light"

Good luck!

I've fooled around with my A 28/2.8. For one of the night shots, I used ISO 800 and F 2.8. I took it handheld, and the shot came out very well. Maybe this was just a fluke, but F 2.8 didn't seem all that slow to me. Now, I tested it inside at ISO 200, and to my surprise, F 2.8 was quite slow. I had to use the flash almost always to get decent shots, which my M 50/1.7 could take easily.

It all comes down to what shutter speeds you can get. If you want to stick with ISO800, and (for example) f/2.8 gives you 1/50s (which I think is pretty decent light), f/2.0 would give you 1/100s, and f/1.4 would give you 1/200s. That's really all is boils down to.

Really difficult to get multiple people in focus at f/1.4, though. This is where ISO 6400 comes in.

If I'm doing group shots, the flash comes out most of the time anyway. When I'm at f/1.4, I'm either composing carefully so the thin DOF isn't an issue, or I stand farther back. It can be done, but flash usually gets better results.

Although the supposed great high ISO quality of the K20D may change alot of things for us!

LOL

I also think that F2.8 is a bit slow, in a dinner or party, if the subject is not moving too much it might be enough, but i think that the minimum acceptable to me is F2 (that's where my FA35 comes in :P).
