Judging by the angle of the plane it appears that you must have shot it down!

There's several versions of the 55-300 lens as well to add in to the mix!

If you want something longer (and less expensive than the150-450), the now discontinued Sigma 150-500 maybe worth tracking down.

I presume the US price is without sales tax.

The Tamron version seems to be available in supported mounts for half that price!

It seems given the degree of perspective compression that occurs when shooting a face with a lens greater than 50mm focal length that 80-100 mm is most flattering.
Fish-eye lenses can prove quite interesting for the opposite effect!

I recently bought a 62mm version of these for a Sigma 28-105 UCIII lens.
Whilst it is an elegant design and the concept works well, in practice the quality of manufacture makes it unusable !
The plastic threads on the adaptor ring are undersize and the internal threads on the locking ring are large which means it is impossible to lock the adaptor in place as the ring just jumps over the threads.
I contacted the supplier and they sent me a rubber hood (with a metal screw thread) as replacement.
I may have just been unlucky - but be aware !

Meanwhile, if anyone does have a spare old Sigma 62mm bayonet fitting lens hood please let me know !

Do you have a local second hand camera dealer near you? They might have one in their 'odds and sods junk' box!

If it has to be a bayonet version, that's what I linked to at a very reasonable price. Give free postage is included it's at virtually zero cost. Why would the lens focus method be an issue (unless the part the hood bayonets onto rotates of course?)

Ooh... my care package has arrived! Plenty of heft to this box. Will have to inspect and lay out everything in photos for y'all later.
Have already had a quick look; everything looks pretty serviceable. One or two little niggles but for the price paid, I'm happy.
Didn't appreciate Social Services were able to supply those, and that with budget cutbacks etc !

There seems to be quite a bit of overlap in availability, at least, if not manufacturing.
Well I'm pretty sure they weren't going to throw any unsold 'oldies' away. Even now some the older FAs are still available new along with the newer D-FAs.

I gather some of the rarer lenses were only made to special order.
