Looking at the recent images posted of the DA15 and then seeing the Photozone results, I decided to purchase the DA15 Limited.

As many of you already know, I have the DA14 f2.8 and it is one of my most used, and therefore, loved lenses. I have many photos on my wall printed to A3+ from this lens and they look wonderful and sharp as a tack.

I also have the DA12-24, which is also sharp as a tack, but I have not been as enamoured with it as many here are. A great lens no doubt, but it just doesn't suit me or my style and is also rather large.

I also use the DOF scale of the DA14 quite extensively and it also focuses much closer at 170mm compared to the DA12-24's 300mm. For me, these two limitations mean that the DA12-24 rarely gets used. In the following posts are some flower shots taken with the DA15 Limited and many of them were taken at or near the closest focus distance of 180mm which goes to show the value of the ability to be able to get close.

As you all know, the DA15 is a very small and light lens and apart from the fact that I wanted another Limited lens, due to the Limited lens' usual outstanding IQ and build quality, I also wanted a small and light ultra wide angle lens so as it would fit in my bag easier. I can now have a DA15 and another FA Limited in my bag where the DA14 or DA12-24 would normally reside. :-)

To say that I am quite astounded by the IQ of this little lens is an understatement. This little lens' IQ has blown me away. It is a true Limited in every sense of the word, IMO. It really has the ability to render a 3D quality in the right circumstances. Take the time to look at the flower images to see the 3D effect this lens can deliver.

All the following shots were taken RAW, converted in Silkypix to 16bit TIFF. In Silkypix, CA was removed and there was a little contrast adjustment. Once in Photoshop, I used a little Noiseware Professional noise reduction on some of the flower photos as they were taken ISO400 and ISO640. In some images I may have used a little bit of highlight/shadow adjustment. All were then reduced and sharpened for web view.

All shots handheld, even down to 1/13 sec. SR is not apt to work at closer than about 400mm and many of the flower shots were near the closest focus distance of 180mm.

All EXIF in tact.

Images in reply.

In this shot, the sun is actually in the frame in the top right hand corner blown out (obvioulsy). How good is that for flare control!!

looks like you got a good copy ;)

All very nice (both sets)! Quite the lens, isn't it?

Next trip for you: to an antique shop, to buy some mothballs for your DA14 ...

Hi Lance

I knew it would just be a matter of time until you got the 15 Limited lens to add to your collection! It is indeed sharp and your captures with it are excellent, Does or will your Cokin Filter System fit on it . You seemed to indicate in another post that the built in hood might cause difficulties with that.
Nice shooting mate! Though I doubt your 14mm lens will be mothballed! ;-)

Very best regards
Leo

The subjects in focus looks nice.
Thank you.
But the bokeh is not especially pleasant.
Like all bokeh, it depends on the background distance, the focus distance, the aperture and the background. I have seen some very nice examples of bokeh with this lens.
Looks like a supernice lens though.
It is at that.

I have yet to try it. When the lens's hood is retracted, it still sticks out past the lens's filter thread so I need to use an empty 49mm filter ring in order to be able to mount the 49mm Cokin adaptor ring onto it. I shall then see if it vignets or not.
Nice shooting mate! Though I doubt your 14mm lens will be mothballed! ;-)
If the above system vignets with the Cokin set up, then I shall not be mothballing the DA14 :-)
Very best regards

I enjoyed your day lilly series very much, not only because it demonstrates that the DA15 is a fine lens but because I used to collect many varieties of day lily when I lived in Melbourne.

As for vignetting I took your advice some time back and bought a slim line Cokin-P holder. To fit it to DA15 I used a 49mm filter with the glass removed. It vignetted.

Then I took a closer look at the filter I'd screwed into the DA15 and realised that the filter protruded about 1mm past the end of the retracted hood.

I removed the filter and rubbed the front against a piece of silicon carbide paper until the filter was flush with the retracted hood. Now there is no vignetting.

Thank you very much for the tip, David. I shall try this myself. :-)

Congrats Lance! I have had the DA15 since it was first available and have loved it ever since. It has become one of my most used lenses. It balances very nicely on my K-7.

Your shots are fine illustrations of what this lens is capable of.

The only downside of the lens may be its front cap, which is of a screw-in design. Thus it takes a bit more time to out it on or take it off (I rarely leave the front element of the mounted lens exposed between shots), but since I generally take my time for a shot that's not too much of a problem. On the contrary taking the time to remove the cap makes me operate more consciously in a way... Resulting in a better thought through photography. I can imagine missing some shots because of this as well though... What's your take on this? Did you replace it by a traditional cap or are you using the screw-in original?

I can very easily see why as it is a fabulous lens.

Did you see the shot in the first series with the sun in the corner? How good is the flare control!!

Just like the DA14 was for me and now the DA15 will probably be as well. :-)

I think I will just use the screw in cap, like you do. I agree with you, "taking the time to remove the cap makes me operate more consciously in a way... Resulting in a better thought through photography."

Whether I actually get a better shot or not because I took the time to operate more consciously is another thing! ;-)

Yes David, one of the first things I did when I got my DA15 a week ago was to do just what you did to use my Cokin P Grad filters (I do the same on my FA31 which I have had for 4 years but of course the angle of view isn't an issue with that lens)

Luckily the filter I used (and old Asahi Pentax) was thinner than say the normal hoya filters but still it's a very close thing and at F/4 focused at infinity there is soem vignetting. Just changing to close focus virtually get's rid of that (see below) but maybe I need to do what you did because I think the difference is down to parts of a millimetre to solve the issue!

Infinitty focus @ f/4



Close focus at f/4

It just goes to show that there is much more to lens performance than can be revealed by bench tests, such as those done by Photozone. Nice work, Lance.
