Would you swap your DA12-24 for the DA15mm?

Apologies to anyone who has read this thread elsewhere but still trying to decide whether I should buy the DA15mm as I currently own the DA12-24mm. The size/weight issue isn't really important to me, I'm mainly interested in the rendering/contrast and ultimately complete IQ (not just sharpness) of the lenses. Obviously it's probably easier for someone who has/does own both to answer this one for me,

I'd appreciate people's thoughts

Thanks

Simon

Even if I owned a 12-24 I would not swap it for a DA15, maybe a sigma 10-20 or 8-16 though.

I shoot a sigma 10-20 presently and it is a key part of my vacation and travel kit, where I use it for about 60% of my vacation shots (a Tammy 28-75/2.8 does the rest).

Of the shots taken with the 10-20 about 50 % of all those shots are taken at 10 mm. I would really not enjoy being limited to 15mm. Note I also own a samyang 14/2.8 and while it is a fine lens and very good in low lit due to the speed, it is just not wide enough in many situations when travelling, especially in older cities where things are close, and you just can't back up further.

If you are not into really wide, maybe the 15mm is ok, but if you use the limits of the 12-24 you will miss the extra FOV

If size/weight is not important, keep 12-24mm, you unlikely to get better IQ from DA15

this is why i want pentax to release a wider prime. i am always at the wide end of my 10-20. either 10 or 12mm (v.little or no distortion at 12). i would like a really wide prime to be part of a small travel kit for architecture. i don't think that 15 is wide enough though. and the 14 is too big to justify the change from the 10-20

I'd love to be able to answer this question. I have a number of UWA lenses including the DA 12-24 - which is my favorite - except for the DA15. It gets so much praise that I'd love to make that comparison. Personally, I think one needs both and one of these days, I'll have both. At that point, the question is what will I no longer need. I can't see me getting rid of the 12-24 though.

I'm a prime lover, but versatility is also important to me. So I have gone with the 12-24 as there are many times I've needed/wanted wider FLs than 15mm. Even the 12mm was a stretch at times for me. I have no personal advantage to having the 15 ltd. I find the 15 ltd excellent nevertheless and it packs a great IQ in such a small package. For that reason alone it makes a great classic lens. But I still prefer the added utility of tge 12-24.

If I was looking for 'discrete and versatile' paired to a K-5 while on the move, I'd consider swapping a 12-24 for a 10-17 AND a DA 21. The 10-17 offers unique options from 10-15 then becomes more normal 15-17. The 21 would be my urban walk-around lens. To complete this travel kit, I'd add an FA 43 for speed and 55-300 for reach,

Cheers... M

I have a DA 15, I used the 12-24 for about 2 weeks along with the DA 15 before I kept the 15 and returned the 12-24. However this was because:

1. Size was important to me. I have the tamron 28-75 as my walkaround lens and when needed I wanted to use the DA 15 to swap out. Its so small that it just goes in the pocket.

2. I was not that interested in the real ultrawide end.

I debated for a while because the 12-24 seemed sharper, did not see any big difference in image quality otherwise but in the end I had to look at my existing lens and how best to match it.

On the other hand if you look at the 'DA 15 limited controls my mind' thread on this forum, the people who like this lens are very passionate about it...

Got the DA14 and a 15LTD. I'm in the market for 1 or 2 more 15's for back ups. Great little lens!

The14 is OK. Got 3 stars at Photozone for IQ

The 15 and 12-24 got 3 -1/2 stars.

Sigma 10-20 got 3 stars.

I was going to buy a 12-24 but then the supply dried up. Looked like Pentax was coming out with a new model. so never bot one. Sigma is pretty cheap for what it is. Great build quality in a compact package. I'd strongly consider it. Read up on them at Photozone.

I use my 10-17 for snowboard photography, but i hardly use it on a city break holiday because of the distortions, and wanting to maintain straight lines in architecture- which is why i got the 10-20. then i have my 40 as my standard lens and 77 for details and portraits. (50-200 is reserved for waterspouts really, i don't ever take photos of things at 200mm besides birds except water sports)
i don't know if 10-17, (15), (21) ,40, 77 would be as good as 10-20, 40, 77.

for discreteness and IC, i would prefer 15, 21, 40, 77 - but the 15 and 21 would probably take up as much space in my bag as the 10-20, without the extra wide end.

to be honest i think that i would be best sticking with what i have and complete the gap between the 20 and 40 with the ltd zoom planned

If it were a straight swap, I'd swap my Tamron 10-24 for the 15Ltd. Then I'd sell the 15Ltd and buy another T10-24 and something else too. I don't find the specialized 15mm focal length useful enough to sacrifice the UWA zoom range. I have had both the DA10-17 and Zenitar 16/2.8 for years, and they see much less use since I got the T10-24. And my T10-24 doesn't see lot of use at 15mm.

Personally, I consider every photograph an experiment. As such, I do not see distortions as a negative. Every lens has distortions to some degree (zooms more than primes). In fact, I try to take that into account during the capture and post process. In post, I crop to compose (heresy ) to a square format (double heresy ) then attempt to make the distortions work in ways that add strength to the story built into the photo. Sometimes it fails, but I'm not afraid and am always game to give it the ol' Yankee try.

Cheers... M

This really does come down to personal preference.

The DA14mm is an excellent lens with the main advantage of a full stop extra on the aperture range - it's heavy, a bit bulky (more so with the hood attached) and not very forgiving if you get your angle of shooting wrong. I owned one for a few years until I got hold of a DA15mm Limited, then I was able to try them side by side and for me there was no great difference in quality (14 corners tended to be a bit softer at wider apertures). I sold the 14mm for two reasons only - 1. The 15mm is so compact and light and 2. My "need" for the extra stop of light was cancelled out by buying a K5 (which moved the acceptable ISO upper limit significantly for me).

As for the wide angle zooms - I can't talk with any real authority here, I haved tried out the 12-24 but I found it too bulky and awkward - the results did look sharp and contrasty so I have no doubt it is a superb performer but it's not for me.

My choice when I go out shooting is to take a few small primes (usually the DA15, DA35macro and the A100) or two zooms (DA*16-50 and FA*80-200) - depends on how much weight I can tolerate

Thanks for the replies everyone...as I mentioned in my OP though the size/convenience factor really isn't a consideration I'm too concerned about, I'm very much interested to know if the DA15mm produces images with that little special "something" that the DA12-24 just can't replicate - or ultimately are images so similiar that it really does just boil down to a decision regarding size vs focal range?
