AFAIK the new one is optically identical to the non-WR (which I have also recently purchased, in its Samsung disguise) with the exception of the aperture: the new WR has more aperture blades giving (in theory) rounder, smoother bokeh.
You sure?

normal
WR

All that differs is
- housing (aluminium +WR)
- rounded diaphragm blades
- coating (Super Protection)

Also in theory rounded diaphragm blades does not give rounder, smoother bokeh.
Bokeh is simply the light distribution inside the Circle of Confusion, and yes that will become round but not smooth.
The smoothness of the out of focus blur is primarily defined by the optics so no you'll not see a difference in the quality of the blur but the round highlights will look more round instead of an octagon.

For someone that has a DFA 100mm the only reason to upgrade is for the housing really, better build quality and WR are nice things to have.

Machine gunning is quite good for taking pics of set pieces like penalty kicks. You can put them together into a sort of movie!
Indeed it has his uses I wouldn't deny that
But I don't think it's a feature you need to have.

Yes we start of like that but later on the K7 got throw into the mix a bit and the comment you quoted was from Geoff with him comparing the K7 to the KX.
So that's were I got the K7 from.

Sorry for the misunderstanding

Stacking images does rather rely on your subject staying still

I'm not sure what he's doing exactly. If you read his write up on this image he talks about taking 66 photos of a fly, handheld, on a leaf on a windy day, and getting 3 in-focus shots which he then stacks. I don't see how he can possibly have the fly in the same position every time.
Well if get lucky or shoot a lot like 66 shots, there are images that ere very close to each other and with photoshop there is an option to automaticly stack and align the photos and that works very good.

Wonderful photos Jon, you can probably refurbished the camera to make it more sensitive and of course polish the lens coating away of your lens

Konrad that's not true take a look at these
KX
K7

The best the K7 in RAW is
Frame rate - 5.2 fps
Number of frames - 15

The KX with RAW
Frame rate - 4.7 fps
Number of frames - 5

But to be honest machine gunning is not so important with sport, most of the time your better of waiting for the right moment and then the press the release.

As for a second body, you might be better of buying the DA*60-250 if you don't really need a second body that is.

Hyram, help (Instruction of installation) is at the bottom of the page

Angela, yes mac is a problem.
They said they are busy with a MAC version but no luck now

You need to have windows, hopefully you have a friend with that are else you might be able to find some help in a shop that supports Metz.

Yes I already posted it, they did more flights with this setup.

You could ask them to send you the colour profile of their printer if they have one.
I know a few shops here that do provide them and that way you can make sure the colours come out as they attend to be.

As Stefan says, the light from a low pressure sodium lamp is not a continuous spectrum. It consists primarily of two closely spaced yellow spectral lines. These lamps are often used in physics labs, as they provide the nearest thing available to a monochromatic light source. See this Wiki about sodium lamps

You simply cannot filter out the yellow/orange light - because that's pretty much all there is.

Andrew
yes that's very correct

Exactly. That's why a colour temperature filter wouldn't work and one would need a proper filter like the Singh-Ray Lucalox job I linked to in the first page of the thread. i.e a notch filter rather than broadband filter. I was trying to think of ways to notch out certain a single light frequency ( treating the closely spaced freqs as one for all practical purposes ). It turns out the colour cast removal method in Photoshop (linked above) works quite well. Indeed the inverse colour looks pretty much the same colour as the Singh Ray Lucalox filter.
Singh-Ray Lucalox is a colour temperature filter like what you can read for my earlier posts.

Here is a read about colours with photography link

I've looked it up what the colour temperature that you need.
High-pressure sodium light 2100 Kelvin

The K7 will probably be able to read this right in automatic white balance since it does well with tungsten but the older models have more problem there.

I've done this with the white balance inside lightroom 2, does it come close?

If you've a RAW you can do it better.
here is a little test of mine.

Have I now convince you it's colour temperature?
