It looks like I really need the 70mm Ltd.... but some other cheap options to look at before I can justify the cost of the 70mm, is there such a thing as "just one more lens" as I've been saying that for about a year...

m42geo - #6 : you are right, there was a pillar right next to me obstructing my view. In fact that is only around 1/4 of the full scene so next year I'm going to find a better spot and make an 8-10 shot pano.
Alan #3: I've noticed that too, it must be the uploading, resizing because although dark the detail of the full tower is there in the original.

#3 is my favourite - and although I love low DoF shots in this case my taste differs from Pentaxophile's as I actually find the sharply in focus vegetables add to the scene.
I think possibly you do need to work on your compositions though - almost all your portraits are centred and I'd personally like to see them given a little more space in the direction they are facing or positioned off to one side if straight on (the rule of thirds is as good as any to get you started on composition).
Sharpness of the 18-250. Not bad and that's a nice shot of the eagle/hawk but look at the clumping of the feathers, the detail you'd get from a better lens would blow it away so it is a little soft at the long end (at either end from what I've read though not experienced).

For portraits you may consider the soft focus lenses such as the Pentax two 85 softs ; 2.2 or 2.8, which should be perfect (sharp in the centre othewise dreamy), not too expensive and easily found, there's also the Tamron Adaptall 70-150/2.8 Soft Focus.

Wedding togs swear by the Tamron 28-75/2.8 which may be the best bet for you.

I think anyone that is saying they can sharp focus in manual is probably using a larger depth of field and therefore a large margin of error. I cannot see how it is possible to manual focus otherwise.
The DoF at f1.2 and say 10' (3m) is roughly 6" (15 cms) if you are steady on your feet and the subject relatively still (e.g standing chatting) then it's not that difficult to attain focus, however by 10m that DoF has risen to a whopping 2 yds (1.83M) !
At f1.4 and using the parameters above then it's nearly 7" (17.5cms) at 3M and 2.7 yds (2.14M) at 10m.
This was shot at 04.00 at a distance of around 18" (45cms) with the only light coming from reflected light from a single lightbulb 5m away. No flash. f1.2, ISO 1,600, 1/6 sec, Hand-held. DoF is 3mm ! Note the Cosina is a little softer than the K50 wide open (funky bokeh though), it looks even sharper before being resized and loaded onto the web, though this one took maybe 6 or 7 efforts before I shot one in focus. I think shooting a lot of hand-held MF macro shots helps to make these shots easier, so what I'm saying is practice makes perfect !

The 77ltd is double the price of the 70Ltd? Perhaps a s/h 70ltd could be a 'stepping stone' to the 77 Another one (within reasonable budget) would be something like the Tamron 28-75mm. The Yanks on the other forum seem to love it.
