composition wise:
try to look for s-curves, receding lines and repeating elements, rather than simply following the rule of thirds...
level the camera if you want to keep vertical lines straight.

when shooting group shots if you line your subjects in a straight line the persons near the center will appear alright but the people near the edges will appear distorted and smaller especially with fisheyes and ultra wides, the fix for that is to line your subjects in an arced curve with the persons near the center being the furthest from the camera and people near the edges standing closer to the camera....

the wide angle distortion is always the result of distance from the camera and the tilt of the camera...
the more your camera is tilted the more verticle lines will bow and converge.... the closer something is to the camera the bigger it will appear relative to everything else in the frame.
hope that helps.

In good light or daylight I'd say the x90 is capable of matching or beating my old sigma 400 on my k10.. so i'd suggest taking a camera like the x90 as a backup body and using good glass on your d-slr... if you cannot afford a good tele, this is a decent alternative.... the 55-300 is said to perform well.. and it sounds like you need that range anyways..

speaking of k5..

seems like the k5 is about to be tested by pop photo...
interesting choice of subject matter.... take the Pentax into what is traditionally Pentax's achilles heal... fast sports....

also photo pro considers the k5 a pro model....

What derogatory, descriptive words would you use to describe someone that compulsively has to be oppositional and defiant, with no regard for the majority? Some people are just a little more ODD than others...

the bottom line is
it's thier house, thier rules.
not about who is right.
typin unlike speaking, you have time to edit... it isn't like you can SAY oops, that slipped off my tongue.

I don't think a kx body with the pentaprism hump lopped off would be too ugly...
look what a d-slr looks like when rigged for video:

yes.
How long between the first digital 645'images and mock ups, and the actual release?
What matters if it has the sensor from the kr or kx and good video!

yep rumours of a digital 110 (whose film size is within a half a millimeter of the micro 4/3's system)...
Rumours of pentax evil with photo:


if true note that big flange around the lens mount... lens release in the right spot and looks deep enough to be a standard k-mount! the marked points would suggest that flange spins and acts like samsungs e-dial...
This could be the camera I've been asking for!

So you're saying only the words in the English dictionary are ok?
People have been banned for using words out of that book.

Seriously, the language changes, and even if you want to argue over what words are acceptable, you'll then have a forum to open up debate on which images are acceptable as some wi probably try to push boundaries that edge towards nudity to pornography.
I don't think you have to agree with the moderators policies.... but people that strongly disagree have the option of leaving and starting their own forum.

I'm for having an adult section. I think that as an individual, I come from a disadvantaged background, grew up in some mean streets and while kind and generous by nature, I am a little rough around the edges.
Be a shock for somebody to get to know me on a "Moderated" forum and meet up in person and find out I don't talk as politely as I type.
to quote Maroni from "Johnny Dangerously":
Not a single real bad word there.
Moderate that.

Lighten up people, it's their house try respect their rules.

congrats!

Carry over from my youth when I was in Martial arts. If the knuckles break, don't cry, just hit him with the heel of the palm. If that sprains the wrist, don't cry about it, just hit him with the forearm. If the forearm breaks, don't cry, just hit him with the elbow. Eventually he will go down.

Try the work around while they work on a fix.
