Default Opinions on the DA 16-45mm f4

I am considering a lens purchase and have narrowed it down to the DA 50-200mm WR to add some foul weather function or the DA16-45mm f4 to add a more flexible wide angle end (I currently have the DA 14mm f2.8 and the DA 10-17mm fisheye zoom). I have an FA 28-70mm f4 and I really like its sharpness, the DA 16-45mm f4 seems to be the APS-C equivalent, a moderately fast constant aperture zoom.

I can't afford the DA* lenses so the under $500 range is where I have to look.

Any comments or suggestions? Anyone have this lens (16-45) and have anything good or bad to say about it?

Evening Ira,

Actually that it a harder question that what it might appear. You are essentially trading the gap between 14 and 28 against 14 and 16 as one choice.

Your other choice is weather - especially going into winter up there (although today it was 108 here - and I am so tired of the heat).

Wide angle flexibility vs weather sealing.

I have had the 16-45 now for 3 almost 4 years. I like the lens a lot. However, the 12-24 has taken its place because of the wide angle flexibility question. The price has fallen on the 16-45 from $400 down to a bit over $200 since I bought mine.

I have also have the second kit lens - 50-200 but not WR. I would guess that with the winter up there, this would come in handy. With the 55-300 my 50-200 has not seen a lot of use, but I have a very sharp copy, since others Harriett have found theirs wanting.

So, with winter - do you expect to take more wide angle shorts or moderate telephoto? That may be another way of addressing the issue.

I probably did not help you too much.....

Hi Ira

I also have had the 16-45 for several years now. Purchased it When i purchased my K200D.
I really like this lense, more so than Kit lense. And as such is in my travel bag.
However, I tend to take the majority of my shots with my Pentax FA 28-105, so its use is limited.
If it would help I could throw it on the camera over the weekend and take a few shots with it.
In the end, I agree with Interested Observer. It really depends on what you are going To Use the Lense For.

Phil

Well you did clarify the conditions. It will soon be dark for 24 hours here, just various degrees of dusk around midday. This would imply that the 50-200mm may in fact get little use until February or March. Meanwhile indoor events will take place, but the f4 may not be fast enough to handle it! I guess I have a lot of thinking to do. I didn't take the DA 14mm with me but I may pick it up when I visit home again.

I have the 16-45 and I like it very much. I find it a sharp, reliable performer, that functions fine in cold climates. It's not as sharp as the 12-24mm but that's not a fair comparison, when you consider the price differential. I think it's much better then the kit 18-55.

I also recently (4 months ago) bought the 12-24mm and that has more or less replaced the 16-45 for my wide angle shots.

I use the 16-45 as the usual lens on my KM as a general, daily carry around combo.

You have the 14 mm F 2.8 which is significantly faster then an F4 16-45...although the 14 mm doesn't give you a zooming capability...and sometimes it's nice to zoom to a near normal of 45mm...but that 14 mm is wider and faster.

For extreme wide angles and of course, mostly present distortion you have the f 3.5, 10-17mm fisheye, which I also have.

I find with the 10-17mm, that at 17 mm and if I work at finding the correct angle...I can get pretty fair wide angle shots with minimal...but still some distortion and of course the 10-17 is a bit faster at F 3.5.

I also note that you have the 50mm F 1.4, which I also have. I'm starting to use it now for evening shots as we are having less light now...thinking of your limited outside light and indoor pix. It's true it's a normal lens, almost portrait (35 equivalent around 70-75mm)...but I'm just backing up more...LOL . In fact last Sunday at an outdoor car show...around 7:00 PM...losing ambient light rapidly...I took my 12-24mm F 4 off my K10D and slapped on the much faster 50mm F 1.4. It's a wonderful prime lens as I'm sure you would agree.

I don't know as lens choice is always a personal thing...but that 14mm with it's F 2.8...both indoors and outdoors....you might already have what you need for wide angles.

I'm rambling on.....not sure if I've helped either.

Hi Ira, I have the 16-45 and I find it to be very sharp and it is the only DA lens I have other than the kit lens that came with my *istDS. I took this shot with the lens at 16mm with my K20D and I really like the way it works.

I think your 14 mm makes lots of sense up there. What about looking around for a K or M 24 or 28 mm f2.8 for a more "normal" fast lens to go along with your 14 and 50? That might be a good idea for indoor stuff. I have the 24 f2.8 and it's a really sharp lens. I used it recently for the first time in years and was really impressed - can't quite figure out why I don't use it more, it's much lighter and smaller than the DA 12-24. I know they can be hard to find and may be selling for some ridiculous price though.

Normally I'm a big proponent for buying lenses over cameras, but in your case I think buying the K-5 should be really high on your list of priorities. That way you can use some of your current slower lenses and use higher ISOs. If the 16-45 really is as cheap as somewhere around $200, it would could be a good addition, along with a better high-ISO camera like the K-5.

Good point, if I had the better camera I could make more effective use of the lenses I have now.
