    THere is the characteristic warm cast that comes when you use ND110.

    Did you use manual focus? Also, what F/stop?

    Guys which bg would you prefer?
    #1, I like having more green, makes the bg less dull.
    My photos - see just some or all of it =)

    Just received my K-5 yesterday after finally biting the bullet. First impressions: WOW!!! I haven't had a chance to put the 7fps and AF-C performance to the test, that will come tomorrow at some indoor basketball games. However, I did get to put the camera to good use at an event with super low light and check out its reputed high ISO capabilities. I was shooting at ISO 6400 and 12800 all night long and the noise performance is roughly comparable to ISO 1600 and 2200 on my K20D. I don't really mind the grain (which looks quite film-like actually) and there is none of the purple/magenta cast that shows up on ISO3200 upwards on the previous generation sensor. ISO 25600 (expanded ISO) is a bit nasty as the purple cast shows up but that's in comparison to the ISO 6400 image, which still blows me away. I would shoot ISO 25600 for my coverage for the school newspaper (previous upper limit was ISO 3200 only), but I'm really not sure whether I will ever need to go that high. I'm really quite amazed by the low light shooting that the K-5 opens up for me.

    One downside is that in that situation I was struggling quite a lot with the reported tungsten low light front-focus issue. The camera was confident in locking on, but the image was quite consistently front focusing. I'll have to try the camera out even more to see if this problem is manageable, especially in slightly better lighting that I find myself shooting in more often. I personally hope that Pentax will fix this problem in the K-5 because the FF is just letting the fantastic sensor down.

    Lastly, the interface is totally different from the K20D so I think it will take some getting used to. I also intend to shoot with both bodies at events but the different button placement and user interface might be a problem.

    Here are some photos I took last night, I think you will agree with me that these samples are nothing short of impressive.

    ISO 12800, f/2.8, 1/45


    ISO 12800, f/2.8, 1/125


    ISO 6400 f/2.8, 1/90

    Thanks! My standard PP work involves some exposure, contrast adjustments, toning, vignetting and slight NR in LR3. I prefer to leave some of the grain than to totally get rid of grain at the expense of a "smeared" look. I was using Tamron 17-50 for the first shot and Tamron 70-200 for the last 2.

    thanks, marcus. that's a good suggestion of tilting the lens to link the two sides of the lake. will try out in the next outing.

    My 2cents
    appreciate your dua kupang. next time will try different exposure time.

Before you shoot next time, make sure when you set it to Manual focus, also set your focal distance to infinity. You may have adjusted that unknowingly.

    My sun shots were destroyed because I forget to cover my viewfinder!
    thanks for the help during the shoot and the comments here. how come need to cover viewfinder?

    Not sharp maybe 'cos the jetty was moving slightly? Anyway, we can't tell that it's not sharp.
    yup, it is the B+W ND110. the sky doesnt look sharp, i mean. didnt do much correction during pp. as this is my first time using ND110 didnt know the orangy cast was so pronounce.

    Yup, the focus was set to infinity with f8 stop and 20s exposure. on tripod with ISO100.

    guys, thank you for all the comments and advices, especially bernard for setting up the meet at pandan reservoir.

    Thanks Ken. Shot them at Punggol East.

    I was lucky to see it fly out to the open and stayed long enough for me to get near to take some shots.

    Thanks Bernard. It's the glassland near where you all go and shoot the bridge. That place is going to be gone soon to make way for a golf driving range and sports hub.

    Hi Ken
    Excellent shot!
    Prefer the first one as I am colour-biased.

    Very nice, Cornelius. Always trying to learn to take such portraits with such sharpness and details.
    And your Barrage scene is fantastic too! It looks so un-real. Like a scene from Terminator....!

    thats some poison for 17-50.. i think it's a good choice of bumping the ISO to get 1/45s, otherwise the old lady's hand might be blurry due to her movements.
    and best of all, the noise is hardly noticeable!

    I was testing to see how far I could push the ISO on the K-5 and I'm really impressed with how that turned out. ISO 12800 is just unbelievable.

    Thanks Arthur. I'm still testing it out, just shot some basketball today. The AF is definitely better than K20D but still nowhere near bai fa bai zhong. But the higher FPS is really great. Give me some more time and I'll be able to post more detailed thoughts on the new camera. I'm quite sure you will like it when it comes

    Thanks Bernard. I'll be sure to post a lot of K-5 poison, hopefully more and more people upgrade to this fantastic camera.

    Thanks Denis. I wish I could've gotten it earlier but the price was prohibitively high for me until now. Spend about as much as you guys did but missed out on almost 4 months of shooting with it.. Better late than never. My K20D sensor conked out the day the K-5 arrived, so perhaps this is all fated
