KAF4 lenses were first introduced around 2016, Sigma were still producing lenses for Pentax in a very limited range which were mainly KAF4 compatible until they announced they were withdrawing from the brand. Unless Pentax start selling significantly more bodies then third party lenses will always be very sparse. I would guess Irix, Laowa and Samsung are happy to do so as none of their lenses are autofocus so cost is minimal (which is great for us as they do make some fantastic products)

I think even if the others still made lenses I would still go for the Irix ... it looks excellent and there is a thread all about it on Pentaxforums. Remember it's manual focus only though.

Basically Tamron and Sigma can make a lot more profit producing their lenses in the other mounts due to a higher user base.

The K-1 screen is a sort of jack of all trades but master of none ... it tilts every way but not enough to be 100% useful all of the time.

Personally I have 3 camera bodies and all of them have a articulating screen, as I see it I could do without it but it's a handy thing to have on the odd occasion such as macro or when you need to hold the camera up at arms length. I honestly cannot see why some people feel the need to run them down though, if you don't need it then don't use it (it's not like the have any detrimental effect on using the camera) but having it there keeps all the others happy as well and for what, a few extra £ on top of what it would have cost without. It also keeps those people using Pentax and not moving elsewhere. The same goes for touchscreens.

Anyway, my APS-C needs are being met with another make now and I have no interest in the new body, it's too little too late but my K-1 and full frame lenses will be staying with me for the forseeable future because it's a great camera.

I have one, how much are they worth at the moment?

Really interesting progression, enjoying watching it but it would be nice if you kept it all in one thread so I can just bookmark it and then click daily to see if there has been any action

My 60-250mm and Sigma 70-200mm f/2.8 OS went in favour of a D-FA 70-200mm f/2.8. It's an excellent lens but I find myself just not bothering these days, carrying hefty glass just get's me down now, I think it's been out only a couple of times since I have had it ... much like the 15-30mm and 24-70mm.

Out of all the lenses i have had I do miss my 60-250mm.

(and my Nikon AF-P 70-300mm f/4.5-5.6 but that's for another place)

Mmmm, I have a garage full of stuff like that.

Tell me more Kris

Canon D90 is about it I think.

D500 may be 3 years old but it's one hell of a camera, Nikon haven;t been able to get anywhere near it with mirrorless, the Z50 isn't half as good especially where AF is concerned.

Seems strange to me we have not heard anything about this new body for months though, beginning to wonder if we ever will tbh.

For a moment there I thought " that's unusual, a bearded cat".
