Help with lense choice please
was going to buy second hand but again, not sure
More than likely it would be the Sigma though as it has faster AF ... There is also the Tamron 70-200mm f2.8 if you can't find a Sigma.

thanks very much

The Pentax 60-250 is lighter and has water resistance - autofocus speed is good enough, but it's likely to be the more expensive of the two.
I will get looking
Pro's
Its f/2.8,
Its all internally Zoomed & focussed (doesn't grow on Zoom or Focus)
Has the fast, accurate HSM, possibly more reliable than the SDM on the 60-250
Is very quiet during focussing...
Switchable Image stabilization
Solid as a rock quality build....
Cons...
It is a bit on the large side
Not as 'WR' as the 60-250 perhaps

A few bits & Bobs
Fastest and quietest AF speed at this focal range
Very nice rendering and compression

For most Pentax camera bodies... While doing certain types of physical activities and carrying a camera (in most any type of rucksack/gadget bag) turn OFF the Pentax in camera SR. I've seen many cameras accidently either left on, or bumped into the on position. In which case, it is eventually possible to have issues with the SR and some Pentax camera bodies.

What are people's thoughts on this?

Sigma don't make the 150mm macro in Pentax mount and tbh you would be much better off with a zoom lens of some kind for the sort of subjects you are looking to photograph.

I have a Pentax K5ii and would live some advice on a lense to capture the riders both coming at me and whilst they move past at speed.
Any advice would be greatly recieved
