Re: GESO - tango @ ISO-6400
I suppose I should offer Igor my apology for totally hijacking his thread... I did not want the comparison between the PESO and this image to ensue. This image was the initial calibration shot - I took as it were and then eventually zeroed on both on the exposure and on the desired impression. I merely wanted to show that at ISO 25600 K-5 is extremely good even if it is dark outdoors.

Re: GESO - tango @ ISO-6400
Well, Igor was kinda boasting with low light performance of his camera. I thought I might show an image shot at 4 times higher sensitivity and with older camera :-). I kind of think that perhaps beside the AF improvements (which are to be verified) K-5II and K-5IIs don't offer too much - mostly some far after decimal points digits on some test scale...

Re: GESO - tango @ ISO-6400
Igor, the most recent PESO of mine was also shot at ISO 6400 (but on good olde K-5). Link: http://pentax-ways.blogspot.com/2012/12/peso-2012-57-night.html Here is one of the initial takes of that PESO that I've taken at ISO 25,600. It is processed to taste, mostly having to deal with color cast on the waves and some noise reduction... http://www.flickr.com/photos/borispdml/8280913447/ By the way it illustrates my point to Bob W about the structures on the left... EXIF data for ISO 25600 shot: DA* 16-50/2.8 @50mm f2.8, 1/25 sec. So indeed this sensor and this imagine engine are extremely good under very low light conditions.

Re: GESO - tango @ ISO-6400
Rick, heh! Humans are weak, aren't they? You've got some interesting photos there. (Is that your daughter?) The technical nuance is that the gallery I put out consists of shots taken at ISO-6400. They aren't the best shots from the evening, but I appreciate the quality that I wouldn't have been able to obtain with my K-7 without the flash. Not having had any personal experience with K-5, I am not in position to compare K-5 vs K-5 IIs. (That gives me a hope that I won't gain an extra hater this week.)

Christine, I haven't tried much since the last weekend, about which I wrote here, on the list, earlier: http://pdml.net/pipermail/pdml_pdml.net/2012-December/332613.html [*] About misses I had. 1. Focusing in 11-segment AF mode was sometimes choosing the wrong object. Switching to the center-point AF helped. 2. Some shots had focus that is good but not perfect. I am not sure if this was the effect of motion of the subjects, motion blur from hand-holding the camera, or the AF error. I don't jump in claiming the latter. In my, yet limited, experience, the AF is better than that of K-7. But I might be imagining that due to the desire to have that improvement. (People say that K-7 and K-5 AF was similar.)

When using a long lens, you may find it even worth pushing to 8,000, or even up to 16,000 to get the shutter speed you need. Next time you are out, try varying the ISO up to ridiculously high levels. For future reference it'll be handy to know just how hard you can push it. I've lost more photos to too low a shutter speed, and even too little depth of field than to too much noise. (Some NR, in the range 35-70 for luminance, was applied in LR, except for the 2nd shot, _IR00019, where no NR was done. For that shot, NO image manipulation, except cropping and resizing was done, - hence some noise can be seen). Color temp seems a bit off to me. Have you tried pointing the white balance dropper at some point like the white collar or black jacket of the guy in image _IR00019? And some of these photos are fun by themselves (IMHO). Comments are (as always) welcome, including constructive critique and recommendations. I have been finding that my biggest challenge lately has been autofocus. As you mentioned in another post, one issue is with size of each focus point being too big, so you think that you're focusing on someone's face, and you are focusing on the striped shirt of the person three feet behind them. It's also difficult to see to manually focus in the dark. If the dancers are staying fairly stationary, you can try live view and manual focus, hit info a couple times to zoom in. I ran into a friend at a West Coast Swing dance last night (not my normal thing, but they were local and had a live band). He had just gotten a G5, and commented how difficult WCS is to photograph. I took that as a challenge. I also played a bit with his G5 and 20/1.7 lens. There are certainly things to like about a good EVF, and the G5 is nearly there. I haven't seen the images from his camera yet, but the sensor seems to still lag quite a bit behind the K5. On DxO mark, it comes in comparable to the K20. I was checking out a K30 review and it seems to have quite a few features that I really hope make it into the next generation of the high end APS (or FF) body. -- Larry Colen l...@red4est.com sent from i4est -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
Re: GESO - tango @ ISO-6400
Thanks for sharing, Igor. The only image that is important to me, in evaluating the ISO 6400, is the one with no post-NR applied. (Anything else is more an assessment of your proficiency in using the NR tool). : ) In any event, I think the noise in the 2nd shot is quite acceptable and looks more like the ISO 800 I used to get with my first Pentax DSLR, the K200D. If that is anywhere near accurate, that means an improvement of at least 3 stops. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

I have found a monopod invaluable. The data at the bottom is listing lens, but not focal length, but if you're using a 50-135, 1/25 is likely to be a bit slow for free hand holding. Yep. 2-3 shots from these 9 were at 1/25 - I don't remember what mode they were taken in. I am surprised that LR doesn't show that to me from the EXIF (at least not easily). The focal lengths were 50 and 55mm. However, notice the 6th shot (*038), - that was at 1/13 with the 77mm lens). That one has much less effect from the camera shake. So, I am not 100% that a considerable portion of the blur on the photos taken at 1/25th is not from their motion. This can be seen e.g. in the 8th photo (*111), where the pattern on the woman's dress in the middle of the chest (right above her hand) is much more in focus than the rest. Yes, I agree that a monopod might be helpful. However, that's yet another piece to carry. I was still playing with the settings (various AF modes) and modes (S/TA/T priority). I pretty much only use manual and TAv. There are good reasons for various modes. But, I think these photos show the quality of the ISO-6400. It's pretty freaking amazing isn't it.

I've lost more photos to too low a shutter speed, and even too little depth of field than to too much noise. I tried 12800 a bit. It is not stellar but usable, even somewhat better than 6400 with K-7. (Some NR, in the range 35-70 for luminance, was applied in LR, except for the 2nd shot, _IR00019, where no NR was done.

Have you tried pointing the white balance dropper at some point like the white collar or black jacket of the guy in image _IR00019? It would go to a slightly lower temperatures, but I don't want to get a neutral color as if they were in the white light. They were under colored lights. And that's the ambience. Sometimes, I just like leaving the colors the way they were, e.g. http://42graphy.org/swing/swingtet/ or http://42graphy.org/swing/abp-2010/a-thursday/ And some of these photos are fun by themselves (IMHO).

WCS is not more difficult to photograph than Lindy Hop or Balboa. But, as most dances - it has its own specifics. As we discussed with your previously, reasonable knowledge of the dance and the particular music by both the photographer and the dancer(s) plays substantial role. I am looking forward to seeing how different people will take my special class at the Fusion Exchange in January, - as they may have all different dance backgrounds. (Apparently, that class is sold out.) I was checking out a K30 review and it seems to have quite a few features
Re: GESO - tango @ ISO-6400
Darren, I was expecting a response like that, - and that's pretty much why I left one photo without any modifications. However, from my point of view, it is not necessarily how the images come straight out of my camera, but rather how they would look like after _minimum_ adjustment in LR. For NR that means just one move of the NR slider, and not too far, - pretty much near the middle of the range. (That's why I gave the numbers I ended up using for the NR.) Besides, with the resolution reduced almost 4 times, - I doubt that pixel peeping makes too much sense, - it's much more about the overal impression such a photo gives. ... but I am glad to hear it was useful to you! I estimate the low ISO performance improvement to be of ~2 (+/- 0.5) steps. Igor Sun Dec 9 21:24:33 EST 2012 Darren Addy wrote: Thanks for sharing, Igor.

What does it have that the new K5s don't have? Focus peaking? that is one of them. I was watching this: http://www.youtube.com/watch?v=9RMfSRpEASg And remember that he mentioned a couple other cool features, which have completely slipped my mind. I'll poke around. One thing that I see which I really like is that the K30 has swapped the display and LV buttons from the K-5: http://www.imaging-resource.com/PRODS/pentax-k30/pentax-k30A.HTM I often hit LV when I don't want to, and it can be a pain in the ass trying to hit the review button when my left hand is full. Expanded area autofocus looks very handy. -- Larry Colen l...@red4est.com sent from i4est -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
