Originally posted by Welsh Dog I must be missing something because I've been looking around for a decent all-purpose lens and have never seen an 18 - 300mm lens for the K-r.
I've seen a Sigma 70 - 300 mm which works with the K mount... and a Pentax 55 - 300 which doesn't. I'm really looking for a decent (i.e. fast) long TP lens but so far 300mm is the largest I can find that will work with the body.
?? I wasn't aware of a Pentax 55-300mm model that wouldn't work, or even one of that zoom range that isn't made in native K-mount.
Could you please elaborate with more details on that?
Btw; "Fast" and "> 300mm in zoom" are generally mutually exclusive characteristics in the consumer or even prosumer lens world.
One example being this below, for those with an idle USD38k lying about

200-500mm F2.8 APO EX DG - Telephoto Zoom Lenses - SigmaPhoto.com Originally posted by Welsh Dog
My 'impossible ideal' would be an '18 - 500mm' but if anyone can suggest any sort of long TP lens that will work properly with the K-r I'd be really grateful.
Hehe. :ugh: I suspect that range of zoom may remain impossible for quite some time yet, and even then, could take much much longer to become of 'ideal' capability.
Fyi: Sigma made a 50-500mm HSM zoom in K-mount, and a 150-500mm HSM OS too.
They are both known to "work properly" on Pentax K-mount, and, are generally considered quite reputable in both performance and value too. Some owners affectionately refer to them as "Bigma".
Both have now been discontinued I believe, although you might be lucky to find a new one still gathering dust on some outlet's shelf, else test the s/h market space.
Their announced replacement is a single 50-500mm APO DG HSM OS zoom, although I've yet to spot one of those (in K-mount) on the retail circuit yet.
Correction: seems like it is available now, in the US anyway, although I'd want to confirm that it's a current OS model before putting money down. Often Sigma lenses are generically described, but come with their K-mount variant missing OS (or HSM), while models for Canon and/or Nikon mount do have it (often at same price too, a Pentax owner rip-off IMhO!).
Built-in OS is a
very desirable feature to have, for hand-hold, at that extreme. And Sigma have been moving to incorporate it over most of it's newer replacement range for Pentax K now.
