Optimal range coverage with zooms for K-1?

The Tamron 10-24 is made for APS-C but is usable full frame in the 15-24 range. Sample below at 15mm:

The Samyang 14/2.8 is already very good (as is the Irix)

Many samples have been posted here (with links to full sized images)

That image shows pretty heavy vignetting in the corners. The IQ does seem to be good to the edges though.

I don't know why it took me so long to realize a simple thing, top glass wide zooms on FF will be heavy and expensive. Period. Heavy! That's the reality. I want too much.
So, nothing will change, I stick to the plan: D-FA 24-70mm and Tamron 70-200mm for K-1. And primes in between, 15mm, 20mm, 35, 50, 300mm,

There s a Sigma 15-30 if you can find one on eBay. A buddy of mine managed to get one off eBay.

For Pentax? I didn't know that existed.

Yes for our Pentax K mount.

Sigma 12-24 is ff and is cheap. If you find one, it might be your way of getting UWA range covered.

Also people swear by the Tokina 20-35 zooms. I bought one off ebay for like $130 but my copy was decentered and I sent it back. I've seen people posting images taken with good copies of those and they look great. I ended up buying dfa 15-30 since I wanted the ultimate performance for landscape work and don't mind the weight, but I've ran into two bad copies in a row from Adorama, now waiting on a refund to try somewhere else, fingers crossed..

I've been using Rokinon 14 2.8 for a while now, and I quite enjoy the lens. I believe their QC has improved in recent years, my copy is very good, no optical flaws that Ive noticed. Irix 15 is probably better because of screw in filters, gel filter insert in the back and weather sealing.

There's not much out there, apparently UWAs were just not all that popular during film days. I'm sticking with my FA-J 18-35 until something better comes along. There are various 20-35, 24-50 type zooms, The question becomes would you e happy with one, and could you find one.

By the way the FA-J 18-35 is tiny, When Pentax does come out with something hopefully it will be half the size of the 15-30 and F4 instead of ƒ-2.8. But it could be years or never.

To the OP: When I purchased my K-1 I also purchased the Tamron 28-75, which you have, and the Tamron 70-200, which you are planning to buy. I purchased these two because of financial limitations and considered them both temporary, planning to slowly add primes as finances permitted (so I'm working in the opposite direction that you are). My use is exclusively for landscapes. My assessment of the 28-75 is basically th same as yours - good but not great. However, the 70-200 has been a very pleasant surprise - it's image quality for my uses has been great. Most of my use has been at the longer focal lengths and the sharpness is impressive. I have a 20X30 print shot at 200 with about a 1/3 crop and the sharpness is remarkable. Thus, although I may eventually buy primes in this focal range I am absolutely keeping the 70-200. If you do buy one I think you will be happy with it. Mine is the version prior to the new G2 version which is said to be even better in reviews but I'm not sure
if the G2 is available in Pentax mount. I hope this is of some help.

Neither G2 or G1 are available for K-mount. I believe the only Tamron 70-200 available for K-mount is the older Ld Di Macro. I think last 2 Tamrons have optical stabilization that wouldn't be necessary with most of the Pentax cameras

Yep, unfortunately no updates from Tamron 70-200 for Pentax, but even the old version looks pretty good, imo. I also tried to love new DFA 28-105mm lens, and I searched tons of images, but 24-70mm seems more, I don't know... special perhaps.
Sigma 15-30mm would be actually good to cover wide range, but it's hard to find these days.

Anyway, at least I finally stopped brainwashing around what zooms to plan for K-1 in case I need to cover an events, especially indoors when I don't have so much space for primes, and I believe 24-70mm is so far the best solution for small spaces of wide angle pictures. Tamron 28-75mm is also a bit noisy which is ok for the party, but may be a problem for not loud event if I need to cover it.
