Originally posted by Biro Has anyone worked with both the DA 15 Limited and the DA* 16-50? If so, can you relate some real-world advantages of this particular prime over this particular zoom other than size and weight?
I own the DA*16-50, have owned the DA 16-45, and am trying the DA15 out this week (rental)
First thing to note is that 15 mm is just about the right amount of wideness. I haven't really run into a situation yet where I wished it was any wider, whereas I sometimes wish this at 16 mm. The DA15 is just excellent when it comes to flare and distortion control. I really think the lens was specifically designed as an outdoors/landscape lens.
I'd give the DA15 the edge over the DA16-45 at the wide end due to the DA15's lack of chromatic aberrations and of course the DA15's tiny size. The DA16-45 does perform pretty well at 16 mm though, considering it is a prosumer zoom.
Against the DA*16-50, the DA15 performs much better in terms of distortions and lack of vignetting. On the other hand, the DA*16-50 has much better bokeh and the f/2.8 is essential indoors. I'd also give the DA15 the edge in terms of focus speed and close focus ability. I think I like the DA*16-50's color better, but that's just personal preference.
Basically, if you're going to use the DA15 as a walk around lens to supplement the DA*16-50 I'd recommend it. The DA*16-50 spanks it in poor light and of course in general versatility. But since the DA*16-50 is weakest at 16 mm it's actually a pretty good combo with the DA15.
I'd say the DA15's only glaring weakness is that it is a f/4 lens, but since that was done to assure the lens' portability that's a fair tradeoff if you plan to use it a lot outside.
Hope that helps.
