k-5 menu section 5 button customization, shutter button half press, enable AF,

Hi, thanks for the suggestion. The shutter-button-half-pressed enabled autofocus works fine with the other lens, and did work fine with the Tamron too - it's the only way I've ever focused. It's just that with no warning the Tamron lens suddenly started not to focus at focusing at shutter-button-half-pressed even though the shutter-button-half-pressed was enabled.k-5 menu section 5 button customization, shutter button half press, enable AF,

But I discovered that cancelling the autofocus at half press and as I say just using the back auto focus button works. Don't know what's happening there.

Hi gang! here's one for your little gray cells. Beloved Tamron wide-angle stopped focusing in auto-focus on beloved K-5. (AF works fine with Pentax wide-angled light lens). Sent for repair came back same after couple of shots. Endless groans as going on holiday. However, and here's the thing - playing about, I found that if I use the Autofocus Button on the back of camera instead ... it works. Anyhoo, I guess it's one for the boffins at Tamron and/or Pentax. However, I was wondering if anyone could throw enlightenment on this anomaly please?

Right - quite a bit to try there. I'll go through things in stages, but first, I'll try changing back from Argb to Srgb to see if that is a simple fix - though I suspect I've opened a can of worms for myself
Interesting about Silkypix, I had originally used that when I started out a few years back but PS was a bit easier to use - had been thinking of checking Silkypix out again too.
Will follow this through, but without getting a headache though, as I do love the reds in the landscape.
Thank you so much for your suggesion guys.

Hi Guys - Making headway - wondering about colour calibration though. Jpg looks like what I eyeball - sweet! At home in RAW the greens predominate a bit over reds though? Use PP Hue/Saturation adjustment to get nearer the original - but does anyone know how to manipulate the Tif (for printing purposes) to get colours just as I eyeballed, with a tiny bit less green and a little more red - any ideas? And, yes, I'm nitpicking here. How are your pics coming out guys?

The front 17-50mm fixture can come "undone" and the focus becomes a bit variable. There is an easy fix for this but just check all is solid at the front end. It is a sharp lens but suffers slight distortion at 17mm.

Wise words Martin I'm beginning to get the picture!
I'll check the front of the lens to see if anything is undone'ish.
Lots of things to think about. I'll do some experimenting over the weekend and see what I come up with.
Thanks to all from PammiH.

Stitching is good, but it can fail to work where you have foreground detail very close to the camera (unless you do a vertical pano), and it's very much as case of planning a shot and then cropping your composition afterwards... it's not very immediate.

But sometimes a shot would be hard to achieve in this way, and the perspective distortion of a UWA works in the images' favour. For example when you are taking a picture of an interior, or within a confined space and want to include it all in shot.
Just spotted this. Yes, it's the Tamron 17-50 - it's the 'f2.8'. I've taken good portraits with it but can't use for landscapes - got any pictures with that one?Stitching is good, but it can fail to work where you have foreground detail very close to the camera (unless you do a vertical pano), and it's very much as case of planning a shot and then cropping your composition afterwards... it's not very immediate.

I wonder which lens you mean? Surely not the 17-50, which is so sharp it's almost unbelievable? Have Tamron wide-angle (very, very soft and muddy detail in the landscape)

DA12-24 looks worth checking out. I've a Tamron 17-70 f/2.8 - great lens, but not for landscape - ultra soft and muddy. Don't need extra wide and think the sigma 8-16 would cause distortion but Martyn's pics are really great - like the shapes and the detail picked up, so will check that out too. I'll definitly try the stiching tools you suggest Glyn with my Pentax 55-300.
