I missed this thread. Amateur Photographer just posted this to their RSS feed:
"Pentax has today unveiled a 'weather-resistant' 100mm f/2.8 macro lens designed for use on film and digital SLRs. "

They then hastily withdrew it. Looks like it is real:

Amateur Photographer just posted on their RSS feed the following title:

The story link doesn't go anywhere at the moment, though:

Maybe they jumped the gun.

On. Although using a monopod helps greatly with shake (I always use one), there's still shake and SR still helps.

We're missing a section in the forums now that the K-7 is out

This is my terrible first uploaded video. It's silly, short and shaking all over the place. But it was great fun. I just need to take that tripod with me next time (can be viewed in HD):

I'd suggest you go ahead and send it back. If you've got a K20D backup (which I had too) then at least you can survive until the K-7 comes back again.

I received my replacement K-7 today (#3384xxx c/w #3377xxx) and the problem is not apparent. I did an extended test on it and the dreaded green line didn't show. I'm cautiously optimistic :)

That's a ladybird larva (ladybug in the USA). I'm not sure if it's the same species as here in Europe, but it appears to be the 7-spot ladybird (Coccinella 7-punctata)

I'm returning my K-7 with the exact same problem. Shot a five minute video and then subsequent photo's have the solid green stripe down the frame. It's most easily seen if you heavily underexpose a shot of a dark surface. The effect did disappear after a few shots. I was able to recreate the problem. I hope the replacement doesn't have the same issue :(

Here's a resized image showing the issue I see:

Rense, you're much too kind.

Many thanks for the comments. I know they don't necessarily show off what the K-7 can accomplish, but they have shown me that it is a step up from the K20D.

My first outing with the K-7. What an absolutely wonderful camera. To me, it's a good step-up from the K20D for a variety of reasons, including:

1. The lovely quiet SshSsh shutter, compared to the clunk of the K20D

2. I'm seeing improved handling of noise (I've had to do less NR as part of my workflow)

3. Better flash exposure control with the macro ring flash

4. Smaller and lighter, it's surprising to me that I noticed this but when you're spending hours hunting down insects, even a little less weight and a slightly smaller camera make a difference

5. Much better menu system, especially the INFO screen

6. I don't miss the SR button, it's easy to switch in the menu (two clicks)

7. I prefer the new SD door, quicker to swap out cards

8. Not a fan of the new strap lugs

9. Don't like the new AF switch - it seems it might break and isn't as easy as the K20D to turn

10. The AF assist light is great for focusing in dark spots

11. SDM focus doesn't seem any faster, but screw focusing does

12. I'm happy I upgraded so far

For all the images - K-7, IS0200, DR, SR, f/16, 1/180, AF160FC, monopod. RAW, processed in Silkypix and PSP:

Hi gus, many thanks indeed for your comments. The flash and Sigma 180mm work very well together. You do need a stepping-down ring as the largest one in the AF160FC kit is 67mm and the filter size on the 180mm is 72mm, but those are easy to come by and cheap (unlike the rest of the setup). I've not had any vignetting, but then you don't shoot wide-open in macro normally.

Thanks you for the replies.

Marc, with the spider, I took this one vertically and cropped off the top and bottom third of the frame, but didn't zoom into the image at all. All but 1 and 3 and 1:1, so ~20cm from the from of the lens.

I'm always amazed how well the come out as my hands do shake a bit and the Pentax SR works wonders, despite what some report about it not working well at macro distances.

Gary, my general technique is using the K20D on a small ball head on a monopod. Set the monopod length so I can get some pressure on the ground, regardless of the angle it is at, I completely loosen the ball head, rough manual focus, and move the camera around until I get the plane right to get as much of the insect in focus as I can. The most important step is to get the insects eyes in focus (not easy when they ~1/10mm!) while taking a deep breath and holding it, moving the camera backwards and forwards. Take plenty of shots. My attrition rate varies, but I do get between 60~80% keepers using the technique.
