KP + m_75-150 f/4 ~ a new/old lens, persuading me to put down the GRiii and re-discover KP joys, especially the viewfinder.

Nice! Because of your pictures I have decided to buy 55-300 PLM ... as my first telephoto
Thanks. Good luck with your new lens. The DA 55-300 PLM is a no brainer for anyone with an APS-C camera with which it will work, whether they have other telephoto lenses or not. The lens fine optics combined with its compact size makes it incredibly useful.

Another shot with PLM:

I was out with KP and DA*11-18 yesterday. Did't think there would appear an evening with wonderful colors. So had noch GNDs etc. with me. Only my travel tripod and the combo. Crazy wonderfull scenery with extremely slight gradations. To catch all of the details the highlights underexposed one stop in addition to the already short exposure time. Got the following result.

Hmm. Hmm. Hmm. Maybe I should have used HDR capture mode? Anyway I didn't.



Today using Capture One Pro I tried to get what I saw and felt yesterday evening.

Starting point linear curve. Best chance to get everything visible in the highlights the camera sensor captured - resulting image shown above. After some time I nearly got it. Of course some masking to apply local adjustments had to be done. Only a slight nearly not visible violet hue to the right I'm missing in the image ...


KP • DA*11-18 @18 • ISO100 • f/9 • 1/500s • -1EV

Mabe you enjoy it too?

A short comarison: HD DA15 Ltd. vs. DA*11-18@15

I don’t know where to put this. So simply put it here in this thread because the two captures are made with KP.

Something I wanted to try some time now. Yesterday I took both lenses with me. Erected my travel tripod in front of a tree in a field.

KP fixed to attach both lenses DA15 and DA*11-18@15 after the other. Because DA15 shows it's strength at f/8 I dialed in f/8 at ISO100.

Between the shots brightness of overall light changed a little bit. So I got exposure time 1/80 for the DA15 capture and 1/50 for the DA*11-18@15. 15mm is shown as 16mm for the DA*11-18 because 15 is not available for exif documentation. The images show the same angles of view - so I think this fits.

I used autofocus. Focus on the stem of the tree. Nearly no wind. Light from right side behind me.

Postprocessing in Capture One Pro 20 - exactly the same parameters. No crop. No distortion correction. No CA correction.



KP • DA15


KP • DA*11-18

At first sight both images look the same - no wonder at internet size, I guess. What I can see is that both images show similar rendering. The DA*11-18 image may be slightly more neutral. At 100% they also show similar sharpness in the center - not scientifically measured.

But when I flip between both images, massive distortion of the DA15 image becomes apparent. Looks like the pop effect of projected analog slides when they get warmed up by the projector lamp’s heat. Here's my first animated GIF - was easier to create than I thought using GIMP ...


Now let's have a look at the lower part of the image near the border. Same crop area at 100% ...



KP • DA15


KP • DA*11-18

I'd say here the famous field curvature of the DA15 visibly leads to unsharp areas. DA*11-18 shows much better detail although the grass stands significantly in front of the tree.

Of course this isn't a scientific test. But it shows something that can be important depending on size of presentation.

It is an expected outcome Starburst is better for 15/4.


Maybe, could you, please, provide a flare resistance comparison between these two lenses?

As I've said before, the most prominent characteristic of the DA15 is ... drama.

Since I own both lenses long enough, I expected this outcome too. But I simply wanted to see it in a direct comparison with same scenery and parameters.

The other way around I expect the DA15 being significantly more flare resistent. Indications why I think this is the case, please look into my "review" in the Pentax Forum's lens review section and / or this post. Both lenses have their strength and weakness and IMO it's worth having both to choose according needs.

Next time when I go out with tripod to photograph using the KP in strong light I'll consider taking both lenses with me again. So I could make a small flare test. Please don't expect it'll come soon. Thanks!

p.s. Doing this GIF animation also was a little new challenge I enjoyed.
