Nice, I did one Thursday night as well but as it was done with my Sony a9 and 200-600mm I won't post the actual shot but here is a LINK

Phographing a smallish white bird on a blue sky going from left to right could almost be done with a decent camera phone, certainly a decent compact ... that is not taxing on any camera produced in the last 15 years or so.

If it's correct that AF works much better with PLM lenses then Pentax need to bring out a new version of the 150-450mm asap.

Oh yes. £399 ... even more than I thought.

Looking at the lens in other mounts it seems to be around the £320 mark so allowing for "Pentax premium" I would think the asking price is about right and judging from the amount for sale I would imagine it's a fairly rare lens in all mounts never mind Pentax.

I have a Sony a9 and 200-600mm for bird in flight/wildlife photography and honestly it's like night and day when it comes to autofocus/tracking/target acquisition compared to any Pentax I have had before (not tried the K3 III but from what I have read it's only a slight improvement).

Swings and roundabouts though because for everything else I prefer my K-1

I don't think you will get performance like that without the camera being mirrorless now though, I have had the Nikon D500 and that is probably the best DSLR AF wise and even that wasn't near the Sony.

SRS have one on eBay for £300

This, presumably you got some sort of warranty with it so ask them to repair rather than refund.

Putting this back up for sale.

Bump.

Bump.

I have always found Sigma lenses inconsistent when it comes to focusing, especially the HSM versions and even the primes. I would dial them in with the focus adjustment on the camera and it would be spot on until the next time I mounted it when it would be out again even though it was still showing as adjusted.

The screw drive lenses were mostly fine which is why I still have a few.
