I hate to oversimplify this but the standard ( at least K20)focus screen is pretty much a rule of thirds grid....
The big square is as near as damn it on the one third and two thirds point horizontally. (and only slightly taller than a thirds grid ) Vertically the thirds lines run about half way between the large and small "square" markings.

Save your money unless you take a lot of buildings or seascapes.

Basically tuck your point of interest just inside the curved corners of the large "square" and that's it.

Dublin is a quite compact city as far as the inreresting and historical bits go. Pretty much all of it is within walking distance of Trinity.
O'Connel Street, Temple Bar, Trinity College itself and the River Liffey are all within a few hundred yards of each other.
The Guiness Brewery is worth a tour as well.
Bring an umbrella......

No 8 yes.
No 3 I like but don't think it's what I would expect to find in the PPG.
The others are good photos , just not great photos.


Harsh.....but fair

Welcome to the forum.
I'm afraid it's quite likely the photographs are being blocked by government censorship.
I don't know if there is any way for you to get this website put on their "approved" list.

There's also a working Lego printer video on you tube somewhere.
Some people have too much time on their hands....lucky bar stewards.

I have to say I agree with Dr Nhuni. I go to the PPG to see images to aspire to. I expect to see stunning photos, of the sort you find on 1x.com.
Of late some of the entries to the gallery ,although good or "nice" photos, are lacking the impact I expect for what is supposed to be a world showcase for Pentax equipment and it's users.
I like Gobi trails as it is a well executed photo of a very unusual view, I like Blown out. It is a striking composition. Yes it is blown out but photographs don't have to be technically perfect to be stunning. sometimes you can't get everything perfectly exposed, in fact quite often you don't want to! Look how many grainy old black and white photos are iconic images.
Photography , like art , is a very subjective subject, but many of the recent entries to the Gallery (IMO)are no better and in some cases worse than many of my own images, but I still wouldn't consider my photos worthy of the PPG.

I have one but it has only been on my camera for 5 minutes. I find it too uncomfortable, the finger grip is too narrow for my liking. I also don't have any BIG lenses that would alter the camera balance eough to make it worth sticking on. I should really sell it and get a decent flash....

APS-C at 14 MP is plenty sharp enough for me. I would however, like to see an improvement in sensor noise at higher ISO.
I have now invested too much money in DA lenses to start again for full frame for my hobby. Although saying that, I do have quite a few manual focus FF lenses, which is why I stuck with Pentax in the first place when I went digital.

It may be that the selection is a compromise between sharpness and bokeh(...or depth of field).
Although I have to say I have been quite suprised how sharp many of my lenses (older primes and DA kit zoom) can be at maximum aperature under the right lighting conditions.

But how did the pictures look?
