DFA 150-450 Reporting 310 when at 150
Posted By Tas

Back in 2016 I reported an issue with my 150-450 where the exposure and image data failed to be recorded correctly. I posted the details in the K-1 problems thread (or whatever it was called) that used to be a sticky on the K-1 page but I've no idea how to find it anymore. I still have the affected images and can add that if you are interested.


The odd performance only happened in specific circumstances where I was tracking a moving subject whilst zooming in and releasing the shutter in Ch drive mode. In those circumstances it would record some images correctly, some with wrong information and some of the images were way underexposured.


I have still got the same 150-450 and it still works fine. It might recreate the same thing in the same circumstances but if I'm not doing that it doesn't matter as it works fine in every other way. It's a good tele zoom and I've no plans of getting rid of mine.

No images to share this time just thought I'd post about a new Zeiss Otus: Here is the previously rumored Zeiss Otus 100mm f/1.4 full frame DSLR lens (Zeiss Otus 1.4/100) - Photo Rumors

An interesting beast for sure and with the quality of the Makro Planar 2/100 and Distagon 2/135 they will need to put some effort into creating something better to justify the money this thing will cost.

No ZK mount of course but even if they decided to offer that option I'd struggle to think why I'd want to invest that much on a prime like this.

If money was no object though...drool...

Okay, I've now contacted the winner twice, I guess they don't want to participate as a host as there's been no reply despite them participating in other areas of the forum.

Accordingly, I will open up the floor to anyone who wants to be host of PP Challenge #271. The details are in the first post of this thread for how to be host.

Good luck, I hope the challenge continues on.

Well that's it for PP Challenge #270.

I struggled for an image to choose that was worth selecting over the others submitted but as always it's a close run thing and after about 15 minutes going back and forth through the options I decided on a winner to choose for the next host.

Some notes on the areas of work I liked included the more 3D look of some images where the surfer was not just jumping off the board but also out of the screen. This was not easy considering how hazy the scene was so our winner and todd were two really good examples of this.

D1NO and tuggie76 went with some unique changes each with their own challenges to make them work. That rear leg is at a funny angle and almost looks like a third arm. :lol: Something that would come in handy if he was jumping in with a shark.:eek:

I like some of the tones people were working with, the turquoise look to the wave was particularly good and the colours represented were a wide gamut from mono through shades of colour to strong saturation. Interesting how colour or lack of if influenced the scene captured.

Okay, so that's some observations I wanted to pass on along with my many thanks for those who've jumped into the challenge either as a returnee or a first timer. Whichever one you are I appreciate you taking the time to work on a difficult image and hope you stick around for a bit or drop by the challenge when you can.

That's about as much stalling I can probably get away with so without further ado, I nominate rawr as the host for #270 for this version:



Congratulations mate, I hope you can find something different, difficult or both to throw down the gauntlet for PP Challenge #271.

If you're dropping by or keeping tabs on this part of the forum it is likely that you have an interest in post-processing. It could mean that you think you are pretty good at post-processing or have a unique style that you can create on an image.

If so you maybe interested in participating in the Post-Processing challenge right her on the forum. What's that you say? You didn't know there was such a thing going on?

Well this is your lucky day as I am here to off you the opportunity to test your PP skills and software to make something of this:


The above image is a jpeg of an unprocessed DNG RAW file captured with the K-1 and the HD D-FA 150-450. It was captured down on the Gold Coast during a period of big surf generated by a cyclone that was doing a fly-by off shore.

The image looks a bit soft but this is mainly due to about a kilometre of salt spray between me and the surfer.

This image is posted as a shameless plug for the forum's Post-Processing challenge where you can have a go at making a successful image out of this if you are up to the challenge. The details can be found here if the challenge interests you: PP Challenge #270 - PentaxForums.com

Okay, I've been away for several challenges in the last few months so I'll jump in again if your selections from this challenge are unlikely to proceed.

I've chosen an image that will let me add an 'ad' into the K-1 and sporting images threads to see if any there are interested in coming to join us. I'll see if I can find a lens thread for the 150-450 too and add it there as well. I'll post a link in the post-processing forum too. Hopefully the admins won't get too cranky with me.:eek:


Oh, and this one will be a bit different to work on because of the conditions on the day challenging the detail I could capture through about 1km of salt spray.

I hope to see you all again here: PP Challenge #270 - PentaxForums.com

Hello and welcome to the Pentax Forums Post-Processing Challenge!

For those that are new around here the challenge is based on a person being selected from the previous challenge to provide a full size photo (typically in both RAW & jpeg). The host provides any details and expectations on the challenge like what they are looking for, total number of submission per person taking the challenge or maybe a 'just go for it'.

Usually the challenges run for about a week or so with timings aimed to be flexible as we all have lives outside the forums. At the end of the challenge the host reviews the submissions and chooses their favourite. That person then becomes the next host for the following challenge. Some hosts also provide PP feedback too but this is an individual thing so it's welcome but not a must for the host.

Hopefully you take the opportunity to join us and see how many interpretations can be made from the one image.

Some details about this image:

This was captured with the K-1 and the HD D-FA 150-450. It was captured on a day with a lot of salt spray that has softened the scene somewhat but at 100% there's detail to work with. So the image looks like a simple challenge but when you get into working on an image with so many naturally occurring challenges getting the best out of this image isn't as easy as it seems. So, are you up to the challenge? :cool:



Follow this link to the full size jpeg and DNG RAW file: http://www.mediafire.com/?d029eonoa1cug
For this challenge:

  • If you have any problems accessing the files please PM me so I can fix it quickly.

  • Post as many versions as you like but I'd appreciate it if you stick to 3 per person please as I like to provide feedback on each one.

  • Crop as much as you want however remember that the closer you crop the more obvious the salt spray softening appears.

  • I expect the final versions represent the scene on the day where the waves were really rolling in as they were from a cyclone off the east coast of Australia (it side-swiped us so the surfers were going nuts this weekend).

  • The challenge is open for approx one week from Saturday 15 September closing on Sunday 23 September (in Australia which should be Saturday for Europe and the Americas).

  • We are hoping for plenty of submissions but understand that sometimes life gets in the way. If you can't be host let the challenge host know as soon as you can please.

Cheers for hosting todd, and congrats to jcomley.

Maybe for the next challenge we can add a line that if you are unable to host the next round that you declare that when you post your image version/versions?

This is a great challenge to be a part of and we need to reach out to the broader forum community to let people know about it. Maybe posting to the specific camera thread for the camera used with the challenge link would be a good way of raising the profile a bit and get more people involved. What do you guys think?

I accept your challenge good sir!

My subtle interpretation of a desert sunset.



I went with subtlety but i think this is a scene that will work nicely with some tonal changes and textures...IMHO...YMMV etc...and some mono and well, lets see what happens with this challenge. :cool:

Thanks for giving PP Challenge #268 a go everyone, but now itís time to say goodbye and pass the mantle for #269 onto one of you.
Before I do that, as I committed to at the start of the challenge I will offer some feedback on each version and will add a link to my version that I worked on after starting the challenge.

Something else I mentioned at the start of the challenge was that on the day I wished Iíd turned up with a longer lens. The 70-200 is good enough to allow some serious cropping however if Iíd set up the D-FA 150-450instead the range of compositions Iíd have captured on the day would have been more of what I was after. Indeed, I have two derivations of this scene and both needed a crop for me to be satisfied with what I could create from the scene.

But then the beauty of this challenge is that it provides a platform for a scene to be represented through otherís eyes and it is one of the best things about the challenge to see how other photographers have interpreted the scene and how than worked the image.
So down to the challengerís feedback:

Glenn5995 A regular to the challenge and always a strong contender with what he creates. The excess space was removed and the focus is clearly based on the jetty head and the people gathered for sunrise on that day. The increase in contrast means the environment was lightened whilst leaving the jetty and people strongly in silhouette which works a treat. Subtle work in the sky has avoided any fringing around the sun, a problem that can be compounded in PP. The essence of the warm sun is well captured.

JHfwp I appreciated the stronger reds in the sky here and it is a shame that the compression applied to get it posted have detracted from the sky as the stronger colours were a good call. I especially like the light from the sun extending under the jetty end. It really enhances that feeling of a hot sun over the horizon to the point of making this feel like a sunset.

jcomley Iím never ceased to be amazed at how much detail the K-1 can capture in a scene and this example with an extreme crop really shows how good that sensor is and what Pentax can make it do. The scene best captures why I was annoyed with myself for not taking the longer lens. This is again a warmer looking scene reminiscent of a late summerís day but ironically captured in mid-winter. The lifting of the shadows like this could have suffered with a heavy hand in PP but the more subtle approach has made this image work.

noelcmn 1 Itís always good to see how two versions of an image compare side by side and the comparison between the lighter more golden view from jcomley and the first version from noelcmn highlights this difference really well. Both versions are excellent with the silhouetted jetty and people returning us to a redder sky and the more statue-like appearance of people in silhouette.

todd Thank goodness for the regulars of the PP challenge, and as ever todd has tongue firmly embedded in cheek with some original versions that quite often you donít see coming.
Colour: Subtlety was key to keeping a sense of the moment captured and this is the basis of the PP in the first image. The work done is a Ďzoomed iní view that retains detail and retains the warm glow on the water under the jetty end nicely. The rim light effect is most obvious here on the people furthest to the left and this light effect was one of the parts of the scene that drew me to this capture in the first place.
B&W: Itís like I was shooting this over a lake or swimming pool with the smooth like the mind is tricked into when interpreting this scene. A very original and unique interpretation.
atupdate A challenge to the Ďtongue-in-cheekí award for this week has to go to this version with Godzilla out for a morning stroll, probably out to get the morning paper or something I guess. The highlights around the monster gives this a more genuine feel that a simple layer addition.

noelcmn 2 & 3 The final two versions come also from noelcmn and have struck out in their own way to create compelling interpretations of the scene. The sepia tones and the warm sun looks really good and has an almost vintage look to it. The glow in the sky really makes this scene work so I really liked this interpretation and was therefore surprised as to whether it was better than your final night time version. The cool greys and white sun in version III would lead one to believe this was a moonrise. An excellent effort to create three distinctly different versions.

Well done everyone, the numbers for this challenge were small but the versions created all had merits and this makes it hard to elevate one challenger above the others as all of these versions work.

For PP Challenge #269 I nominate noelcmn as the host for the multiple versions each with unique elements and interpretations, my favourite of which is the sepia version with the subtle light effects in the sky. If there is any reason noelcmn is unable to host the next challenge please pass the banner to todd as his colour version retained the lighting effects that I particularly liked in this scene.

"Hi everybody!"

"Hi Dr. Nick!" (apologies to the Simpsonstm)

Great to see we've had a variety of interpretations on a somewhat restrictive theme, but glad too, to see the different compositions and framing as well as some highly amusement work (glad I didn't see that tourist). :lol:

Anyhoo, it's about 24 hours before we wrap up #268 so if you've been holding off on adding a new interpretation of the image you'll have to get it finalised and posted soon. :eek: So no pressure then. :p


As this was an image I always liked I too decided to do my version so I'll post a link to that when we close tomorrow.


Until the 'morrow. (apologies to Shakespeare)
