LBA strikes again: DA 15mm temptation

Heya,

As a proud and happy K-r owner, I've fallen to LBA.

In just shy of four months, I bought three new lenses:

- DA 16-45 which is a real improvement over the kit lens
- A 50 F1.4, gorgeous bokeh and very fast, even though MF requires quite a bit of practice
- DA-L 55-300, very good IQ even at 300mm, light and versatile

I should tell myself: I've covered the whole range, no need to buy more lenses...

BUT, I hear a little voice inside my head: see, how wide and light I am, how resistant to flare...

In the end it really comes down to IQ for me, would the DA 15, stopped down a bit, produce much sharper and contrasted images than the DA 16-45 at 16 mm ?

I use the 15mm, and it's a lovely little lens, but I doubt it would be hugely sharper the the 16-45 when both stopped down, the 15mm is great, but I think one buys it for it's build quality, it's size/weight, rather than it's optical qualities (if you already have a wide option that is, if you didn't then it's a fantastic buy.)

According to photozone, the DA 16-45mm has better border sharpness at 16mm than the DA 15mm.

Pentax SMC-DA 16-45mm f/4 ED AL - Review / Test Report - Analysis
Pentax SMC-DA 15mm f/4 AL ED Limited - Review / Test Report - Analysis

I think the DA 15 can produce better looking images because it has better microcontrast.

Mat,

The very first page of this long thread may speak to you.

Or maybe something even less rational

Ah, coverage is just the beginning. I've devised a roadmap of excuses, with levels of desire:

1) Coverage. My 10-24, 18-250, and 170-500 cover a huge range.
2) Speed. I *need* faster lenses at various critical focal lengths.
3) Specialties. Fisheye zooms, macros, 1000mm mirrors, etc.
4) Character. Those European 2-ring presets just render better.
5) Frenzy. Looking for incredible deals on weird glass, just because...

Yeah, one can get a 10-20/3.5, and a 17-70/2.8, and a 70-200/2.8, and most needs are covered. But yeah, faster glass is needed at times, so get the 30-50-85mm f/1.4 monsters. Then an 8mm fisheye, then a 100mm macro, then something long and fast for action. Ooh, and now it's time to start collecting Limiteds. It never ends...

Somebody once did some comparison shots between the DA15 and 16-45. After seeing that I promptly sold my DA15. However, I also had (and still have) a Sigma 10-20 which is also much wider and longer and flexible. IMO @15mm the IQ of the Sigma is every bit as good as the DA15. For me, the first consideration when choosing a lens is focal length. You pretty much have 15mm covered with the 16-45. For a DA15 you'll pay almost double the price of what a 16-45 sells (or sold for if it's still available) and gain nothing - except long spiky rays if you like shooting the sun of all things!

If you think you really don't need the DA15, then DO NOT UNDER ANY CIRCUMSTANCES go into jsherman's mind control thread. The lens will be on your camera within a month. I took delivery of a K5 a week ago and the DA 15 has been on for 90% of all my shots.

I feel your pain, Matchete. I recently acquired and then sold the 16-45 since I felt it wasn't wide enough for me. I have both the Tamron 10-24 and the DA15LTD on my wish list, due to their width and their IQ. I really did enjoy experiencing the 16mm side of things, but I know I could find a wider zoom or wider prime that wouldn't have too much overlap with my Sigma 20-40 f/2.8. Depending on what you plan to shoot, would the DA10-17 be a good match for you? I've thought about getting it too and I know RioRico has said before that the 10-17 was why we got into Pentax.

I own both da16-45 and da15 for one big reason and one little one. The big reason is the da15 is so small you can always pocket it and have it for that unexpected wide shot where as the da16-45 is big enough that it does not make the trip unless I plan to use it. Therefore i often get keepers only because I have the da15 with me and would not have taken a larger lens. Number 2, the distortion at 16mm on the 16-45 usually requires correction if there are trees or buildings near the edge. I am quite happy shooting jpg with the da15 with no edits required.

Borrow or rent the da15 for a weekend. You will own one shortly thereafter.

Both are great lenses. "Image Quality" also includes flaring and distortion, of which the 16-45 will give you more. Since owning the DA15, i've found myself shooting more into a bright light source without worrying about all those distracting flares. YMMV. I owned both at the same time and whenever i was shooting at the wide end of the zoom I found myself swapping to the DA15 for the better IQ. I finally sold the zoom but i can see that for shooting parties and moving kids, having a zoom is a good thing.

Wow thanks for all the answers !

Looks like I am being pulled ever closer to the dark side...

Actually I'm quite happy with my 16-45, as distortion is very minimal even at 16mm, and sharpness great from F8 (Btw the comparison on the Photozone forum is unfair as my own copy of the 16-45 is much sharper in the center than what appears on the picture).

However is Santa was to bring me a certain Limited lens...

I think that in the end it will really come down to cost and size, as the 16-45 is BIG.

IQ wise the DA 15 doesn't look like a real improvement to me.
