See if you can find a used Sigma 8-16 (or even a new one if available.) It's rectilinear, and keeps all those architectural lines straight.
Nice pictures! My next lens purchase will be something wider than my DA 16-85. I checked both B&H and Adorama which are the two largest online retailers in the US. Both show the Sigma 8-16 is available, but it is on temporary backorder at Adorama. This indicates it is still available new, and if they have it, other retailers also should have it. It is selling for $699 USD at both Adorama and B&H. Later this year I will be looking for an ultra wide zoom and it may well be the Sigma 8-16, but I am also considering the Sigma 10-20, Pentax 12-24 or if the budget permits the DA* 11-18.

The DA*11-18 f2.8 looks like a wonderful lens. But it will be pretty hefty (82mm filters, 739g with the hood), as is the launch price. Might be some bargains to be had on DA 12-24 lenses too!

...... If you get the DA*16-50 (or another such f2.8 lens like the Tamron or Sigma 17-50) you won't need the 20-40 as well. On the other hand, if you go for the 20-40 instead of the 16-50, you will need to take a wide lens as well..... .
I like your thinking. 20-40 is off my list for now.
I have made my mind up with the DA* 16-50 and I will probably decide on Sigma 10-20 or 8-16

Many lenses are tempting me and will eventually purchase many more lenses however I can only spend so much before I go on my holiday.

IMHO you'll really miss out if not grabbing that Sigma 17-50 2.8 on ebay. Quality lenses like that under $190 don't come around often, especially as it started life as a $700 lens.

Read the reviews here at Pentaxforums
https://www.pentaxforums.com/reviews/pentax-16-50-vs-sigma-tamron-17-50mm/introduction.html
"...For those looking for the best across-the-frame image quality at f/2.8, the Sigma will easily be the best choice."

and scores a 9.13/10 from users
https://www.pentaxforums.com/userreviews/sigma-17-50mm-f2-8-ex-dc-os-hsm-no-stabilizer.html

If you're on a budget (and most of us are) it's an amazing value IMO.

My cheapest option on ebay is $310Aud from China for a Sigma 17-50mm..
By the time I finished work and saw this thread again, there was no $190 option.

Should be now. I emptied my cart, saving it for you until you came to your senses.

You're very welcome, but act fast.

The Sigma 8-16 doesn't come up often on the second hand market (it's not in production in K-mount). There's someone selling one on Gumtree who says that they go for $600-$880 on ebay: https://www.gumtree.com.au/s-ad/east-fremantle/digital-camera-accessories/di...ies/1207458660 That seems a bit high if you look at the sales history on PF: https://www.pentaxforums.com/forums/search.php?searchid=34406818&cx=partner-...8&q=sigma+8-16 There was one in Australia a few years ago for $A500: https://www.pentaxforums.com/forums/36-sold-items/309304-sale-sold-sigma-8-16-4-5-5-6-a.html

A Sigma 10-20 f4-5.6 or 10-20 f3.5 or a Pentax DA 12-24 f4 will come up more often. If you are thinking of FF down the track, the DA 12-24 is partially compatible, as I mentioned. There are also some ultrawide primes, like the Laowa 12mm or the Samyang 10mm, but they are rather big and heavy for travel.

With the DA*16-50, the SDM autofocus has failed on some copies. They can be converted successfully to screwdrive AF. You might find a converted one more cheaply.

Keep an eye on the PF marketplace, although I can't see a DA*16-50 there at present. There are a couple for sale on Gumtree.

Looks good, but doesn't ship to Australia. You can put it back in your cart now @gatorguy ;-)

To be honest, I would want to purchase something like that in about a week or two.
I have committed to buying a couple of things on eBay this week and will delay me buying this item.
"Pentax O-GPS1 GPS Astrotracer Unit" & " Sigma Flash EF-530 DG ST for Pentax" from ebay this week.

I still have the following eBay items being delivered this week :-
"32.5mm M32.5 x0.5 To T mount m42 For Roedenstock schneider enlarger Lens shutter", "PH-RBC Flower Lens Hood Sun Shade For Pentax SMC DA 18-55MM F3.5-5.6 AL s", "Acon R930 Flash trigger set. Immaculate Condition. *EXCELLENT* Near new!", "NOVOFLEX Proson, Variable Length, Bellows Type, Lens Shade For Most Size Lenses.", "Metal Rear Lens Reverse Mount Protection Ring Pentax PK mount Camera 58mm thread", "49m, 52mm & 58mm Lens Mount Reverse Macro Adapter Rings for Pentax PK DSLR Camera", "Male to Male 49mm-49mm, 52mm-52mm & 49mm - 52mm Macro Lens Reversing Coupling Ring Adapters", "3 Ring Macro Extension Tube Ring for Pentax K Mount" & "D-LI109 DC Coupler Dummy Battery+USB Power Cable" all.
I have 1 1.7x telleconverter and 3 lenses being delivereed from facebook for $50.. I could see one is a sun 70-210mm still in the box and the other two were labelled as the lens filters and not the lenses.. - all M42 I and the pics didnt show me what size/range they were. I just bought it for the sun lens and the telleconverter the others are a bonus..
I also have the new 'PENTAX HD PENTAX-D FA 28-105MM F/3.5-5.6 ED DC WR LENS' and new 'TAMRON SP AF 90MM F/2.8 DI MACRO LENS' being delivered this week as well..

Lots of deliveries.. lol

I have been looking at the specs for both the Sigma 4.5mm f/2.8 EX DC Circular Fisheye HSM Lens and the Sigma 8-16 mm F/4.5-5.6 DC HSM Lens.
Both are potential for me. 4.5mm for some astrophotogrphy and 8-16 for landscapes I think. I think I definitely want the 4.5mm.
The Tamron 10-24mm F3.5-4.5 SP AF Di II is another valid option. (I can get one on facebook marketplace locally for $280)
The new Pentax-DA* 11-18mm F2.8 is a very hefty price.
The HD Pentax-D FA 15-30mm F2.8 ED SDM WR interests me a little.
Maybe I will be better off just getting the Tamron 10-24mm Fish-Eye & Pentax-DA* 16-50mm

The Tamron 10-24 that is/was available in k-mount didn't score well in an ultra-wide comparo done by PF staff. There's a new version that's not available to us k-mount users which is supposed to be much better.

I think a used, good condition 17-50 from either Sigma or Tamron or a Pentax 18-135 would be a wise next purchase, and then stop for a while, just getting used to the focal lengths whichever of those you get, which will then let you know if you really want/need a wider lens.

Not going to say a lot - but my 10 yr old Sigma 10-20 f4-F5.6 has been definitely my most-useful & used (and reliable though much dreadfully abused - including it hitting the deck with the camera body and MY body on behind it on one occasion!), sharp (never had to complain about that), heavyish (but not too heavy!) and quick to focus (if a little noisy) lens on many trips around Europe and large country houses in the UK (and in Thailand/Cambodia) on (in order) the GX10 (AKA K-10D), K5, K-r and K-30 over those years, and it'll be with me on the K-70 on the next holiday.

Old, and not HSM, but you can probably find one for less than $200 US - IF you can find anyone ready to let go of theirs

I have one also. I had one for my Canon Rebel. and it was the one lens I truly missed when I switched back to Pentax, so I was delighted to find a K-mount version. I might someday get the new f/3.5 HSM version, but otherwise mine isn't going on the market anytime soon.

PS to my post, that Sigma is almost as rare as "hen's teeth", but there are a couple available in the UK from reputable retailers:
- Buy Used Sigma 10-20mm f4-5.6 Pentax fit - and that's the later HSM version and CHEAPER than the next one which is
- Used Sigma 10-20mm f4-5.6 EX DC HSM Lens - Pentax Fit | Wex Photo Video

I will most likely buy a FF camera in the future in any case so I may want that lens eventually anyway.

You are heading in the opposite direction from your idea of getting a FF body in future. All these APS-C lenses won't work well, or at all, on FF. (Unless, perhaps, you use it with a FF TC and crop a lot: Anyone tried the Sigma 10-20mm f/4.5-5.6 + HD 1.4x Converter on K-1? - PentaxForums.com) If you go FF, you will need to either (1) sell most of what you are now buying or (2) buy FF counterparts and have two sets of lenses. Either strategy will cost $$$. Many members have done one or other of these, but when you are starting with a more-or-less clean slate and a tight budget you have the chance to avoid it.

Of course, for many of us the idea of going FF is something of a pipe dream so it doesn't really matter. APS-C can meet just about every real need for most amateur users, with lower cost and less weight than FF. But be aware that the more you load up with APS-C lenses, the further away the FF idea will be.

They come up in Australia often enough. Here's one asking $A250 "negotiable": https://www.gumtree.com.au/s-ad/watson/lenses/sigma-ex-dc-10-20mm-f-4-5-6/1207149484 Big price gap between this and the Pentax DA 12-24. I don't think HSM/SDM is a "must have" on an ultrawide lens, unless you are taking shooting in quiet places like classical concerts/theatres (or taking wildlife shots from very very close ;-) )
