But its okay, an adapter won't cost must, I just want to get out there and have a little fun for cheap for the time being. I've had enough of trawling.

I based my decision on this forums reviews:

Sigma 400mm F5.6 (AF) Lens Reviews - Sigma Lenses - Pentax Lens Review Database

vs

Tokina (Hoya) RMC 400mm F5.6 Lens Reviews - Tokina Lenses - Pentax Lens Review Database

So user experiences seem to show that the Tokina might be better - but thats all relative to what the user has in their bag and their understanding of what is good and what is not good.

At $117 USD for the lens (shipping $37USD) I'll be getting what I paid for ! lol In fact I'm not entirely sure it'll have a K-mount, it wasn't advertised as any mount, it looked like it was K-mount from my intense looking. If it turns out to be something else, I'll just change the mount, I've got a few dismantled K-mount lens "filangies" lol.

Maybe in time I'll find a tele macro at the right price, but there's more to life than checking ebay all the time. I think the RMC tokina might be a little better in the reviews over Sigma MC, but it'll give me something interesting to do when it gets here.

Hey, If it aint broke .......

It does auto focus Des ?

As far as those prices are concerned ...... I'm out ! I bid something ridiculous and came short. I bought a Tokina RMC MF for a 150 bucks instead.

Maybe if another comes up I'll try again, but not for AU $770, and not with a dodgey gearbox. My K-3 is faster than the K-5 with the screw drive, so I doubt the gears would last long. The gear shafts need a bracket at the top to retain them, so's the shafts don't wobble out under af.

I wish Sigma would just make a new 400mm tele macro.

Looks like you've scored a great lens, pity about the wrong address.

Yeah I watched 3 people try to snipe your lens, and I bet the current one on ebay will have a few snipers on it too !

Hi I saw that auction, and was about to bid, so I re-read the whole ad, and in "focus" the guy wrote "Manual". Though the photos of the box had AF written all over it. Let us know if it can auto focus ?

There should be a fix for it, in-spite of Sigma not carrying any spares. There are shops that sell micro gears - associated with radio controlled cars and planes - so you should be able to find a blank gear in plastic or metal with the correct teeth and pitch etc. The only thing might be that you'll need to drill a hole absolutely in the center on a drill press.

You should also be able to find a suitable ball bearing again through radio controlled stores. I've lost a ball bearing in the same way, you simple empty out your vacuum cleaner, and run it over a wide area of carpet where you lost it. If you can detach the hose and rub it against the carpet you should eventually suck it up. Then empty the vacuum and go CSI looking for it. Hey presto it worked for me !
