Looking for an optically perfect lens that's autofocus and around the 400 to 500mm focal length.

I'm looking for a lens to shoot airshows.

I have 400 to spend on one but I can also part ex my Pentax 1.4x Rear Converter WR teleconverter (bought new and never used) and/or Pentax FA 35mm f2 with correct bayonet Pentax lens hood.

Thanks.

I have a sigma 50 - 500 if it's any good to you?

That'd be perfect! How much did you want for it and do you have any images?

Thanks

Gareth, there has been a few versions of the 50-500mm, make sure it's the newest with HSM as there is quite a difference in AF speed.

Checked out Duster's profile and saw a non HSM 50-500mm that Ken was selling 3 years ago so could be the same lens?

Going off the previous thread, do all 50-500mm have the limited focus throw?

Non HSM/OS isn't too much of an issue if the light is good and the shutter speed is high?

I find a slower shutter speed is better to get a wider aperture. Panning with the movement of the aircraft is key. I'm not sure how useful stabilisation is then, but someone is sure to know.

I had the previous version before the HSM OS but I honestly can't remember if it had a limited focus throw. OS isn't a problem as such, it's handy with prop planes to get the slow shutter speed for prop blur (remember it's quite a bit heavier than the 70-200mm) but you have SR anyway. HSM is definitely faster than screw drive but yes it is possible to get decent shots with the older lens.

Previous version on a K-5

Don't know about different versions of the 50-500. But on my 150-500 the OS was better than I had in the Pentax body. There's also an OS setting specifically for panning, which is great for the slower shutter speeds needed for prop blur.

Thanks guys. Ken's 50-500mm was too good a price to turn down so I'm now an non Hsm OS 50-500mm owner

With you already having the 1.4x then the DA 300 is also an option. It's sharp wide open both with and without the converter.

Agreed, excellent lens - plus I've seen a couple under 500 (second hand) recently

Edit - although it's not relevant now as Gareth has "done the deal" - enjoy your new toy Gareth

Look forward to seeing some shots Gareth, maybe I will see you at RIAT next week

The one thing I did like about the 50-500mm was that you could do this with it ... just managed to squeeze it in @ 50mm. If another HSM OS version came up I would be seriously tempted I think.

Maybe a useful tip Gareth. Before I did my first Air show, I trawled through Mike-P's Flickr account and checked his exif for all the shutter speeds I needed for each aircraft type
