Obviously on a Pentax forum people will submit reasons why a FF is not for them / why FF has no advantage over APSC (which is rather narrow minded) - however the number of Pentax switchers (to Canon/Nikon) simply for FF suggests there is a (relatively) large market for a Pentax FF (as has been amply stated and debated many times on all Pentax forums).

Since adding the D800 to the K5 I've noticed these advantages :

Low DoF without the expense of very fast lenses
Superb resolution enables incredible cropping with the Sigma 500 shooting birds and simply stunning with the Zeiss ZF 2 lenses (35 & 21).
Very wide FoV without as much distortion.
Lower noise at higher ISO settings.
Media photos can be submitted to a wider audience as some outlets, ridiculously, will only accept Canon/Nikon.
Wider range of lenses (enabled me to buy the Sigma 500 which I looked for here for over a year without success, when buying the Nikon I bought it the same day)which the camera can extract the best from.

There is still easily enough room for both systems in my bag The K5 series offers other advantages - it just depends on exactly what, and where, you are shooting.

That's wonderful Chris - well done indeed !

Yet again, with a very good camera & lens in hand, the skill of the tog is the over-riding factor in the quality of the final product.

Superb Mandarin Duck shot Matt (frost shots are not too bad as well)

Merry Xmas to all - may Mrs. (Mr. Ms.) Santa bring you the lens of your dreams

It could well make a difference if you do a lot of heavy cropping though (birding or possibly sport, for example). Maybe not for other genres.

The only time I have ever had corrupt images is when I didn't.

It takes less than 30 secs to reformat a card when you put it back in the camera, why on earth anyone would not do it and take the risk is beyond me.

I don't really understand why anyone would want to edit on a pad/tablet. I have an iPad 2 and love it, for displaying photos, Google Maps, books, pdfs, checking email and a whole host of other uses.

When I first bought the iPad I thought I'd be doing lots of editing and so bought Snapseed etc. played with them and have never used them since. Maybe a pro-tog might see some use but for the rest of us is it really that urgent ?

Of course you have adapters for the iPad if you want to load from an SD card or connect a USB device. Bought them - almost never use them.

Giofi had it right, if you want to edit maybe a MacAir or the PC equivalents is best.

And I make 3 voting for the BR RS4.

I believe a number of K5s misbehaved and this function doesn't work .... it doesn't for me. Ticking / unticking doesn't make any difference but I wasn't going to return it that.

1) Rotation. Doesn't work as on the K7. I too loved that function, all you need is an iPad like on/off menu option but although there is something in the K5 menu it doesn't work for me.

2) It is still there :-
a) display a photo
b) press the 'flash' button on the 4 way controller
c) move to the icon on the left of bottom line of the icons displayed
d) compare as per the K7


It's best to download and read the K5IIs manual from cover to cover (and repeat every now and again) it's the first thing I do with every new camera !
