Only 6277 doesn't work for me, it's the composition, the stones with the moss are to heavy in the frame.
And 6257 looks a bit dull compared to the rest.

It looks like a downgraded Metz 48 and with simpler controls, it might be a winner for beginners.

Won't be cheaper then £100 but it's probably the cheapest you can get.

If it's too sharp it's quite easy to soften the photo in post processing so it's better to have a lens that's too sharp then too soft imho
With light room you select all the photos that need to be soften and then slide one slider.. done, in a matter of seconds you can have soften all your photos.
I think it takes more time to change lenses all the time

I was under the impression from the discussion of the patent Hoya got that the DC motors are an entirely new technology, and more than feasible as a replacement for SDM.
Also, I can't imagine that the new 18-135 requires less motor torque to focus than, say, the DA*55 prime.
The DC is simply a brush-less direct current motor, nothing new about those.
I do think though that Pentax might be the first one to use them in their lenses.
The DA*55 is older then the DA 18-135, also the DA*55 is f/1.4 so probably the elements that move for focusing can be heavier, don't know about the design of the DA 18-135 so can't say.
Also the SDM is more efficient as far as i know.
