It's not odd but not needed in with this photo since the only focus point is the castle.
Here play with this a bit link
With f/11 at 18mm you can get 1.87m in front of you till the horizon in focus, a bit over kill in this shot.
Even with f/5.6 you can get 2.57 meter till the horizon in focus so you could easily have shot this shot with ISO100.

Besides that the noise is there most likely because the sky is one flat surface, it does not show up for example in the building since you've other things going on there, with a decent noise reduction program you can clean the noise quite a lot.

Here what do you think?

Yeah you're right and he sold all of his kit in the mean time, so yes that makes you wander about this thread.
It's also one thread that has gone here sometimes more and the others all ended up by the OP saying that it isn't true all the things we said and him/her leaving.

But the 645D is a DSLR but a mid-format instead of an APS-C, same camera different size of sensor.

Yeah forgot about that.., I wonder why they would do that though.

But it all comes down to what you need from an system, all of their pros and cons non is flawless.
For studio photography I can't see why one brand would be better then another for example, besides a faster shutter sync maybe. With sport Canon and Nikon has the edge with the other forms of faster photography, but the most important thing of all is the photographer himself.
Sometimes all that talk about the latest and fastest AF and the best high ISO and other gadgets sounds like it's never good enough, sometimes that makes me wonder how they thought they made a photo in the early days... those photographers must have been gods to even get a decent photo out of those machines

About the flash triggers the ones dictated to Nikon or Canon support their TTL mode but most pro's don't use that mode since it's inconsistent so all they need is a simple wireless trigger with a middle contact that only just triggers.

The stobist use a pocket wizard for example, mighty expensive but he mostly only use the flash in manual mode so he could easily do with a simple trigger.
This guy link use these triggers link all these do is trigger the flash and nothing more.
If you're going to work with studio equipment, those flashes don't even support any kind of TTL so you will need to work with them manually so just a trigger is enough and that counts for every brand.

So you don't need the fancy pocketwizard that works with P-TTL mode to make good photos, it's the opposite.

ps. sorry for the rant.

Yes the latest one.
The firmware isn't updated but totally replaced so the last one has all the updates.
I've never heard of someone bricking his camera because while updating the firmware, just be sure you've enough power in the battery.

If he doesn't know about the 645D then I wouldn't trust it

Isn't there a plug-in for elements that introduce many of the features photoshop has?

Also thumbs from me for their service, they are fast to respond and they give you good information.

Most likely because the market is too small but the pocket wizard nikon or canon would work on your Pentax but not with the digital communication so you need to use the flash on manual or auto and not P-TTL but hey you're a pro right so you should be able to do that.

The Cactus I had it from Cameratools but that's in the Netherlands I paid €40 for a trigger and receiver I believe. They aren't pro stuff though.
These are better and they work on any standard hotshoe link

What is Pro?
I don't think your equipment make you a Pro though, if you can make the photos you want with a Pentax who is going to say that your equipment isn't good enough?

As for triggers what kind of triggers do you want?
My simple cactus trigger works well even with studio flash system, what more do you need?

Of course Pentax support isn't going to say a third part brand works well on their cameras
