Yeah, Mark's in the midst of splitting systems - gone full frame Nikon, but keeping his K5 for waterlogged walks.

It has to be said that the Pentax 55-300 is quite a bit more expensive than the Tamron and Sigma offerings, so if the Sigma crops up at a good price - even better, secondhand - then give it a go. That's what I did - bought a s/h Sigma, and when I managed to get a Pentax 55-300 at a good price I was able to sell the Siggy for pretty much what I paid for it.

Ahhh - the greater crested blackbird!

I'm sure it would - I'd be interested. I'd imagine they'd be wanting to get it working on the iPad first though from a market share POV.

The other problem is there's a larger market for Canikon versions of these apps. I've been looking into this a little bit too, and the magic word "tethering" helps in my searches. The Eyefi SD card looks like the simplest way to preview pics quickly once taken, and since (from my brief rattle around the internet earlier) Pentax hardware doesn't support live view via tethering then we'll never be able to fully control the camera from a tablet/pc, then this may well be the best we can expect. PKTether looks to be worth a try with a laptop, and who knows, the devloper may put an Android/Apple version together. There's also pkTetherCord - open source - maybe someone will look at porting that to Android?

Here's hoping there's a Q2 with optical 'finder!

Glad you saw sense!

...And if you don't mind manual focus, remember you've got a huge array of high quality glass from the past 30+ years to play with too!

Now on eBay, 99p and no reserve. Finishes on Sunday evening (4th March 2012).

Ahhh - my mistake - I had thought that this was the case with the 40mm jobbie.

At the top it says none: "Taken with PENTAX K-01 ( sample model ) & smc PENTAX DA STAR 50-135MM F2.8 . DIRECT JPG FROM CAMERA NO PS . ReSIZE FOR BLOG"

One interesting thing is that a couple of the photos show the K5 wearing what looks to be the new 40mm pancake - I thought I'd read that it wouldn't fit the DSLRs due to the depth of the back of the mount or something?
