I guess you and I just have totally different priorities. I dont use the 200-300mm (FF equiv)/(135-200 APS) range on zooms hardly at all (its a speciality, rather than general purpose, range based on actual needs for me, and when I go that long, I generally prefer primes ). In the more common 28-200(FF)/18-135(APS) range, I would much rather have a FASTER constant aperture zoom lens/lenses (especially for MANUAL exposure which I prefer for most situations, even on digital at this point due to exposure latitude problems) , and especially for manual focussing which I still prefer on ANY camera in most situations. I really HATE variable aperture zooms, because Manual exposure with them, both ambient and flash is nearly impossible to get consistant results in terms of exposure as you zoom in and out when the f-stop variation is one stop or more from end to end and it often is.

You also lose automatic SR on the K10D, numerous exposure modes, auto-focus and end up with a lens that weighs over twice as much with a filter size of 58mm as opposed to 52mm, it's also larger in diameter and longer!!! but arguably has better build quality. I don't own the DA 50-200 but I used to own the FA 28-70 f/4. I sold the 28- 70 after I tried the FA 28-105 f/4-5.6 Power Zoom, I found it just as sharp and at 70mm the aperture is f/4.5. I'd love to know at what point the 50-200 shifts from f/4 to a smaller aperture value 100mm, 135mm? I believe the DA 50-200 can be had for $100 in the US, I know which lens I'd rather have in my bag, despite the lack of aperture ring.
