24mm or 28mm... I just use f/8 and INFINITY everything from about 5ft to INF is in focus. DOF is all about the diameter of the aperture not calculations based on the smallest DOT you can see on a 10x8.

The Petri 28mm f/2 looks handy. I was looking at these on Flickr this morning....

I'd buy one but I already have the Pentax 'Holywood' 28mm f/2 that I rarely use.

£700 for the KP sounds like a bargain for someone

Looking through a viewfinder you can't see say a car coming from outside the viewfinder so you miss it because you can't react quick enough when it enters the viewfinder. With a wireframe you can see everything that's in your normal vision so you can follow it into and out of the frame

Also better from a H&S point because you can see everything going on around you So you don't get hit over the head with umbrellas etc. quite as often

This is a well known Pentax tog who uses the 135mm quite a lot....

All APS-C which isn't as suitable for a 135mm as a FF is.

The 135mm on FF was an excellent portrait lens. See.....

Pentax releasing one would also give the moaners a few other things to moan about such as they can't get shots in focus

I saw a checklist the other day that had For and Against in the FOR Column it had.....

No 284:: You can use it to take photographs

This isn't good publicity Watch from 19:00 mins

Strangely I've not seen anyone asking for what was the most popular telephoto prime for 35mm cameras Are photographers really that daft these days

People are already complaining that even with a choice of 3 grips the KP is difficult to grip. You can already get a NEW FF Sony Alpha A7 Body for £799 so what are you waiting for

Pentax really need to bring out a Wire-Frame Sports Finder to turn them into a fully fledged Sports brand

Something like the Hasselblad one would be fine

You sound like a 'List Ticker' to me Why don't you try just taking photographs with just one camera and stick with it

It still has distortion

See....

I used to have a Sinar 5x4 so I'm well used to what movements.... Scheimpflug principle etc. can do.

EDIT: It's possible that DXO corrects some of the lens distortions. I've never used it so I don't know.

Shift lenses will still have distortion which needs correcting anyway so their advantage isn't that big.

There are some tutorials on the Hugin site..
