Originally posted by mattb123 In your position I bought the 18-135 for versatility. If I'm in a situation where I can't change lenses (dusty, wet, or snowy) then I want to cover the most versatile range so I won't be tempted to swap.
Later I went on to buy the 16-50 also. If I know I won't need a long shot I use that one. But for example as a ski lens, the 18-135 is really useful throughout the range and the longer end comes in handy. It's also noticeably smaller and lighter.
Hi!
I'm quoting this reply, but honestly thank you, all of you, who replied! I'm more confused than ever.
My initial conclusion was the same as mattb123's opinion, but if the image quality of the DA18-135WR is almost the same as the DA18-55WR then there is not much point in it for me. Maybe I just buy something with ~135mm later... I was thinking about the 2 lens, 2 camera option as well, but I like to travel light, so that would be too much for me I guess. I like that the DA18-55WR is light. That's a very good feature of it. I examined my shooting habits, and I would do fine with a 24-90 range if the long end would have a nice aperture number as well. Too bad, that the FA24-90 is not WR.
Another question: Is it only me, or does anyone else have the same issue? My DA*55SDM lens is a bit hectic, when it comes to autofocus. I calibrated it and it seems to be ok, I just added +1 to front focus in my K5II but 0 default setting looked acceptable as well. It focuses fairly well in high-contrast or well-lit scenarios for single autofocus point, but when artificial light is added (that's only my guess, but I don't know clearly what's the root cause) or low light cases happen, then it goes to back focusing more often than not. But sometimes this happens as well, when it is wide open and the scene is well lit. When I nail the focus, the lens delivers, but sometimes I am a bit upset with the results, when I realized, that it backfocused again. This is the only lens of my collection that makes this chaotic behaviour, so I don't know what is going on. I even considered if I am doing something wrong. But when my subject is 10meters away a little camera movement/shake should not change the plane of focus this radically I think. I added a split-screen to my camera so I can adjust the focus if needed, but it is strange for me... Does the DA16-50 have similar issues?
