What helped shaped my decision in similar situation was the field of view each lens captures. For horizontal field of view:
  • DA 10-17 FE covers 135 to 85 degrees
  • Sigma 10-20 (rectilinear) covers 103 to 64 degrees
  • DA 15 covers 77 degrees
  • DA 16-85 covers 74 to 16 degrees
  • DA 18-135 covers 67-10 degrees
From that you can see just how wide the DA 10-17 FE gets. And if you don't want the fisheye effect, defishing and cropping at 12mm will give you the same as the Sigma at 10mm. Defishing and cropping at 17mm (not much is needed) is equal to about 15mm.


You can also see from those FOV ranges that the Sigma 10-20 and DA 18-135 are a great pair covering 103 to 10 degrees with no gap. The DA 10-17 FE and DA 16-85 are also a great pair covering 135 to 16 degrees.

This seems like a good solution. I had actually penciled out a lens collection roadmap for myself and the 15Ltd was already on it. I'd shop for an smc version and not the HD as I prefer the starbursts from the smc version.
You'll regret it. Get a DA21 instead.

kh1234567890, while there is a certain je ne sais quoi to the DA21 based on images I have seen, and the ones in that link you just shared are really impressive, I don't know that I'd want to get a prime in a focal length I'm already covering with the 18-135 or 16-85 or 20-40. Plus it's not WR. It seems like a cool lens and I might consider it if I could only carry a single mounted pancake but it's just not in the cards right now as I see them.

One prime, I'd go 21 ltd.
One zoom, probably 18-135.

If you need wider than 18, shoot your 18-135 at 24mm where it's razor sharp corner to corner, and stitch. You can stitch to fake wide, there's nothing you can do to fake long.

One increases resolution, one decreases it... but if you have no resolution standards cropping is always a thing.

Stitching is such a faff,just buy the lens you need to do the job!
And what would be the point of having the 21 when the 18-135 is "so good" at 24mm,isn't that just duplicating?

Stitching takes no time with the right software.




DA21 handheld 5 shot (could have done it with 3) pano stitched with Kolor Autopano, HFoV 85 degrees, equivalent to 14mm lens. Took 8 seconds to shoot and about a minute to set up and render.

Size, speed and general 'stealthiness'.

If you need 16mm once or twice a year, buy a lens for that? You still won't have it with you when you need it. It will be ledt home. If you need 16mm all the time by 16-50 or 16-85 or something. Personally I find the Sigma 8-16 excellent at 16mm, and gives me lots of flexibility to go wider. or you could even go for q 15lted. But that's not me.

I was saying if your one lens is prime take the 21 ltd.
If your one lens was a zoom, take the 18-135. I never suggested taking both. Do I have to explain everything?

And do you have to take issue with everything?

Back to the ignore list with you.

I allowed for a second lens if the first one isn't too large. I'm not entire sure how I'll pack my gear; right now using my old Rezo 170 bag carried inside my tank bag or inside my top motorcycle's top box seem like leading plans. I can defiantly carry a battery charger along with the 15Ltd and the 18-135WR in that bag with the K-5. But that's pretty well it.

So I sort of fudged on my own rules as laid out in the topic for this thread from the get-go.

All that for some more trees and a bit more muddy field

15 ltd and 18-135 sounds amazing even if you cheated a bit to get there. Lightweight and useful, I'd go with that.

16-85 488 grams and 94mm long..
18-135 403 grams and 76mm long

The 16-85 would probably be the only other lens I'd consider. And you could make up for the extra weight and length by leaving the 15 home if you don't think you'll need 135.

If space is a premium squeezing your 15 ltd into the bag, the 18-135 is lighter and more compact, but close enough it's only an issue if things get really tight.

You're cheeky and I'm laughing, Kh, but all the photos in the lens club and that I've taken say you've bought a lemon copy.

Sorry, mate. ☺

Btw, partly because of your recommendations (with Norm, Sandy, et al) I've now also got a DA21 and like it.

I usually carry my camera in a backpack or messenger bag on my back to minimize the amount of vibrations that reach the camera/lenses and to simplify the process of stopping to take a picture.

Sounds like a great trip. I've ridden much of that route except for Newfoundland.
