I am hoping to join you too, if I can decide between 28, 35, 50 or 50 mm.
I was interested to read in "The Observer" a week and a half ago, that Sheffield is prominent in the provision of public art. The 'upturned tuba' outside The Children's Hospital (outside the city centre) and numerous sculptures and relief carvings were mentioned.

Lens-wise, 28 or 35 for city-scapes or 50 mm for distant/close-up.
Hope you can make it on Sunday.
Regards
David

Yes, the speed is consistent, I didn't notice it being quicker or slower from one end of the focal range. I'm out on Sunday with the Pentax crew and will use my K-3 with the DA50 attached. I will let you know how it gets on outside in good light, I expect no problems will be found.
I too am a bit confused that my lens doesn't exhibit the same behaviour as yours. Also confusing is why it is slower on the K-3 than it is on the K-5iis, as this is not the case with my other lenses! The only conclusion I draw from this is that my lens is consistent in focussing speed from both ends of the focal range, but differs in performance on different camera bodies. I suspect you have an issue, but I don't know if it's with your camera or your lens.

These are not bad at all and I don't think the noise is an issue.
The one thing that hits me with these is the focus is off on all of them, which makes them look a bit soft. I think it would have been easier for you with a K-5iis, or a K-3, both of which are demons at focussing in low light. Given that you had to use your K10D which doesn't have the low light focussing capability, you have done pretty well I think.
The first one is my favourite.

Let me know if you can't link to it.
BTW, I did notice when doing this test that my K-5iis focusses faster with the DA50 than the K-3 does. Also please bear in mind the test was in dim light (it is quicker in good light) and my K-3 is a Mk1, not a Mk2.

This is the ideal lens for a one lens challenge and could be post free if collected in Sheffield at the sunday meet
Price reduced to £67 if that helps anybody

What I've found so far:
- It is very sharp, even at F1.8 and is much better than a FA50 1.4 I used to have
- It focusses quickly, have not noticed any speed variation across the focal range
- It focusses accurately, even in near darkness and at F1.8
Don't know if this is any help!

It will run, but how well it runs depends on a lot of different factors:
In general an i7 is better than an i5, but it's the whole package and how all the components perform together that determines the end result.

The spec is in the op so should tell you that it's not an ssd, 8gb runs the majority of all modern pc's perfectly well unless running multiple mining and computational threads but Intel's hyperthreading happily takes care of those tasks. The graphics element will has significantly improved with each new incarnation of Intel's current cpu's so onboard will cope with videos easily. The spec tells me there will be something meatier under the hood.
So Louise, the answer is still yes, and yes
If Louise's laptop does not have dedicated graphics, does not have a SSD for example, then I think it might struggle with anything other than small tasks with small video files. There is a huge range in performance terms of laptops with core i5, Win 10, 8gb RAM and 2tb hard drive storage. Without knowing the specifics of the performance of her laptop and the type of processing she wishes to do, there is no way anyone can confidently state 'Yes' it will comfortably handle it.
BTW, my working life is spent working with PC's in a commercial environment.

I go with John Riley on this one, use your higher ISO settings, up to 3200 is fine with a K-5iis or a K-3. This image is one of my favourite gig shots and is hanging on the wall in my music room at home, it was shot with a K-5 and DA17-70 lens at F5.6, ISO 1600:
