At a couple of places I see that the 170-500mm is actually cheaper than the 135-400mm, I want one of them and am thinking that the 135-400mm would be better with the slightly smaller starting size for the photos I want to take.

Thoughts? Should I just get a Kenko MC-7 2X converter, does the MC-7 auto focus with the 55-200mm F4-5.6 DC Sigma that I already have?

Among Sigma's uber-zooms, I'd consider the 80-400 EX OS (optically stabilized):

or the 50-500mm EX HSM "Bigma."

The 80-400mm is not available for Pentax according to the Sigma site and I suspect that the 50-500mm is out of my price range at US$999. The 135-400mm is around US$300-500 and the 170-500mm around the same price.

Ooh, I didn't know Sigma made lenses with image stabilisation!

[Peted]

Looks like it but not for Pentax.

IF the British weather picks up, I will be out shooting with my 135-400. Perhaps the results will assist your choice.

Hey Pete,

centre.net.au have the 50-500 with a pentax mount for AU$1470 which seems pretty good.

Here is their selection of Sigma lenses with a Pentax mount:

Just food for thought.. I have no idea if you can get it cheaper elsewhere, but often it seems that a US$999 product ends up costing AU$1999 when it hits the shops here. So at least AU$1470 is promising.

Cheers

Yes, pricing can be a bit of a pain. Might have to get work to send me to the US again, probably wont be till next Feb though. I don't think that I can wait that long.

I said, I think, that the Sigma 135 400 is £299 in the UK. That's 723 AUD.

[Peted]

That seems reasonable enough, have to keep saving my pennies.

[Rufus]

Finally, some Sigma 135 400 pics, but only 3. Sorry.

Hope this helps!

Thanks mate. Appreciate the shots. I guess I am fishing a bit at the moment and thinking that the 55-200mm that I have is enough for most of what I am doing now really.

That said it is always good to have plenty of ammo so that you are always ready for that great shot. I do like doing a bit of wildlife shooting but will just have to restrict myself to the slower closer animals.

I will buy something bigger I will have to keep saving for now.

Cheers.

Pete
