I love to go on photo hikes and I have had to adjust to a heavier kit with the K-1, as expected. If I anticipate great scenery on a hike I'll take the K-1, 15-30, 24-70 and 60-250, plus a very light travel tripod. I do use standard filters including ND filters on all but the 15-30 due to the need to get a new system for that lens that will undoubtedly be fairly expensive and require additional space in my backpack. So far I've been happy without filters on the 15-30, but I do miss having a circular polarizer and an ND filter at times. I did buy an FA 20 as a light weight alternative but the IQ is not up to the standard of the 15-30 and I lose quite a bit of wideness. There have been a few hikes where I decided to leave the 15-30 behind due to weight. I have just bought a used 28-105 and I'm impressed with it so far, but I'll probably only use the lens when I only take a single lens and probably no bag at all. I've never taken landscape shots in crop mode as that defeats the purpose of buying FF as previously stated. I, like many, would love for Pentax to release a FF 16 or 18 mm prime, but who knows if that will ever happen. The 15-30 is a great lens so I generally think it's worth the weight / size. For some trips, usually when I'm biking, I will take primes instead: 20mm, 35mm, 50mm and 100mm. But I generally prefer zooms since you can't always zoom with your feet and I grow tired of swapping lens. Bottom line, if you can handle the size / weight, I think the 15-30, 24-70 and 60-250 combo is about as good as I can imagine for a three lens set.

In terms of compactness, my landscape kit consisting of the DFA 28-105mm, Voigtländer Color Skopar 20mm f/3.5, polarizer and ND in 62mm and a step-up ring is hard to beat on the K-1. As pointed out above, using the DA15mm just meant to waste a lot of sensor area. I do have a fairly decent Tamron 17-35mm f/2.8-4 lens (neither overly bulky nor heavy and bought for less than a good filter), which accepts 77mm filters. But even if it has to be stopped down for edge sharpness, the 20mm Voigtländer is handling high contrasts a lot better, and I suspect the same would be true compared to the Tokina, which was mentioned earlier. I often also bring (less often use) the 12mm f/2.8 Samyang fisheye, obviously not using any filters with it. Which takes me to my point: For smoothing out water, the above recommended interval exposure composition method works remarkably well, even potentially exceeding the dynamic range which you can capture using a single exposure. Less glass is anyway always good for flare resistance and the K-1 can even do the composition work for you. Even to simulate a graduated density filter, combining bracketed exposures will work in a lot of cases and as pointed out, polarizers are not overly useful in many ultra-wide shots.

So my thoughts: I'd take the 15-30mm without and the 28-105mm (maybe) with matching filters, an extra memory card in addition, and try to achieve what you'd have used filters for on the 15-30mm, by combining multiple exposures.

Another option for filters in a compact ultrawide zoom: Tamron 10-24. It vignettes at 10mm but much better in the 15-24 range. Works with 77mm filters.

You probably should forego either the 28-105 or the 24-70, whichever you think you would use less. That would be my solution anyway. The other space saver would be to trade the DFA 15-30 for a ultra wide prime like the Samyang or Irix 14/15mm.

Paucity of compact high quality WA glass is the primary reason I've stuck with APS-C. The DFA 15-30 is obviously a tremendous lens, but it weighs as much as the DA* 300 and costs more.

A few weeks ago I seriously considered purchasing a K-1, and as part of this consideration, I went online and tried to track down every image I could of the FA 20-35, the M 20/4, and the FA 20/2.8 taken with the K-1. There seems to be come sample variation with the FA 20-35, because I came across some examples that were sharp except in the far corners and others that were quite soft along the edges as well (all when stopped down). The M 20 fared pretty well except in the very far corner. My only complaint is that M 20 doesn't produce the contrast and saturation of my DA 15. I was most impressed with the FA 20, which looked sharp from edge to edge with excellent contrast/color. If I owned an FA 20, I would have purchased the K-1. But the lens is hard to find and expensive when found, so I purchased a KP instead.

If you get a chance to try a K 20mm f4 I think you would find it compares favorably with the DA 15. However, they can be hard to find.

K lenses are manual focus anyway which is always easy for wide angle lenses. Try to find a Zenitar F:2.8 is even more difficult

I was using Zenitar F:2.8 for quite a few ultra wide landscape shots

Thank you all for your feedback. I just returned from another long, foggy and rainy hike in Washington, and this time we divided the lenses ( 15-30, 24-70- 28-105, 60-250 ) between two of us.I think 24-70 and 60-250 were great combo. If serious hiking which I need to be more conservative, then 28-105 should suffice. Ideally, I would love to add a UWA prime to this. Pentax did a fantastic job in the rain. There were few folks with Canon running around trying to find something to cover their cameras.

IIRC the Irix 15mm f2.4 is weather sealed.

Nisi 150 system has adapter where I could use it on smaller filter thread but then I am putting on 150mmx150mm on 62mm filter. With that huge set, you can't leave it on the lens and hike like regular screw-in ones.

I do have Sigma 24mm f1.7 ( quite odd ) with 77mm filter thread which I was thinking to take next time along with 28-105 instead of 15-30. Thanks for your thought.

---------- Post added 09-27-17 at 12:50 PM ----------


I think that would work instead of 15-30, but I don't have Tokina

20-35 would work well for me. I might need to look into it. Thanks.
The 20-35 seems to be extremely overpriced on ebay some jokers sell it for $1200, as far as I can see cheapest one is around $500 plus shipping, and it looks pretty worn out on the outside. Pity, I'd grab one if it was more reasonable.

If you can find a good copy of tokina 20-35 3.5-4.5 it'd be a good lens to take with you, screw in filters, small, and optically seems good. My copy was decentered, so beware. Goes for around $120, very reasonable.
