DA 18-55mm has 6 aperture blades and it's max aperture changes as you zoom from 18-55mm.

DA 16-45mm has 8 aperture blades (rendering bokeh better) and is of constant aperture design (f4 is f4 from 16mm to 45mm). It also has ED glass elements. The DA16-45mm lens is a significant improvement to the kit lens and actually compares very favourably with the DA* 16-50mm lens. Read a comparative review here.

I prefer Pentax glass to any other unless there is a lens that I need that Pentax don't produce. I have only 3 non-Pentax lenses left in my armoury, all Sigma, and 2 of them (70-300mm APO Macro and 135-400mm APO) will be sold fairly soon. I'll not sell my 180mm Macro unless Pentax rekindle their FA* 200mm Macro lens production and I win the lottery (I'm not holding my breath on either count).

These images look perfectly OK to me and consistent with a lens having 6 diaphragm blades. Bokeh rendering at wide apertures is largely determined by the glass used in the lens manufacture but the number of diaphragm blades also makes a huge difference. Essentially a 6 bladed diaphragm will produce hexagonal shaped bokeh (stating the obvious) whereas the bokeh produced by a 9 bladed diaphragm will appear more rounded.

I use Sanyo Eneloops in everything from my clocks to my GPS to my torches to my flash guns. No problems and they are only 2000maH cells.

Alkaline et al batteries will always seem to produce better results because they have a nominal voltage of 1.5v compared to 1.2v of NiMh etc.

4 X 1.5v = 6v, 4 X 1.2v = 4.8v Says it all really.

So do I. Dunno if it would fit my bag though.

DA 16-45mm 1:4 or DA* 16-50mm 1:2.8.

Welcome to the forum. WB set inappropriately for the scene is no problem at all if you shoot RAW, you can change it later.

"Somewhere in Devon", are you not sure where you are? Shall we send a search party?.

Right now you'll not find a better bargain than this. It's a much better bag than the Slingshot 100.

How sad, you would decide to go elsewhere for your purchase just because you couldn't be bothered to pick up the phone?

Lens Buying Affliction/Addiction and yes, you probably do have it.
