Daniel, all of the primes are excellent lenses in day to day use, so I don't see why I would get rid of them. Look at the distortion free performance of the 15mm. Look at the full frame shot. You wouldn't be unhappy with that, would you? I'm not, anyway.
When I got my DA*300mm I was amazed at the detail it produced, here's a shot:

That's shown at 100% (i.e. full size and cropped down), and sharpened. I tried exactly the same sharpening on the section of bricks that Stefan posted and it didn't come close to this. (See this thread for this photo in context, and other examples).
Personally I would be a little unhappy with your lens, but if you're happy with it, that's all that matters. It really looks like it's out of focus to me though.

Just checked the Exif data on this shot and the aperture was F8, Macro. Is this too wide for Macro?
For example: https://www.pentaxuser.com/photo/user-1387/Dragonfly-1006 , taken at f/5.6.

Usually by kit lens we intend the DA 18-55mm M I or II , so reading your first post, it was unclear as where you could find 70mm on an 18-55mm lens.
The results here are picked from several focussing efforts and in each case manual focussing either side of the autofocus results is less sharp than the auto.

I'm surprised by the 15mm one, and also the 35mm to be honest (in the centre). Did you bracket your focusing? Could it be that there's a focusing error with the primes?

There's been a lot of talk about pricing, and I've just had a look to see what the release SRP of the Canon 50D was: £1200/$1399 body only. The K-7 is a whole lot more camera, in my opinion, for less money.
I'm going to love using the video, every now and again, when I get one. The K-7 will be a huge step up from my K10D.

To be honest, I would think most greenhouses are much of a muchness. Why do you need to know?

There was a Nikon F4. Perhaps it was called the F3A in Japan.

A petal hood just gives the most effective shielding without encroaching on the field of view. The 200 and 300mm lenses have round hoods because they give plenty of shielding without having to resort to being a petal type. They could be, but then they'd be at least half as long again.

It says in there that when using video, AF is achieved using the rear AF button. Obviously that's still a draft text, but it's presumably still on the cards at some point.
And Robin, what are all the flaws you keep mentioning?
