Example of AF, DR, high ISO and high shutter speed on K-5

Here is a great real world example of a lot of what makes the K-5 so awesome. I shot these two weeks ago. I was shooting a sigma 100-300 f4 handheld (with a kenco 1.5x on some of the time). I was using AF-C and was in TvAv mode so I could hold the aperture wide open and keep the shutter speed really fast (1/6400 - 1/8000, which are not even possible on my k10 or k20). The low noise and high DR combined with the great autofocus to make these shots possible. I defiantly wouldn't have gotten a lot of these shots with my K10 or 20. This is the K-5 being pushed to its limits, only a mark iv or D3/D3s could out perform it in these conditions, and in some ways it could probably out perform them (DR for example). Many of you wonder if you should upgrade and while there are many valid reasons to do so in everyday shooting, conditions like these are where the camera really shines when compared to the older models...

I've quite done a bit of PP on all the images. My client wanted more drama, let me know what you think.

I am digging the photos as well as the K-5(a proud owner myself, no longer glass for Pentax anymore).

VERY NICE!!!

Whoa, great. I just wonder whether the Pentax engineers 5 years agho designing the K10D and the revolutionary TAv mode had an idea how powerful tool this is going to become. I use it a lot more with K-5 as well. I set both the shutter and aperture and let the camera care for the exposure, as usable ISO range gives generous 7-8 EV of versatility.

Really love the last shot. Has some interesting elements to it.

I have to say this is a impressive performance. Possibly a no brainer upgrading from my K-x.

All nice. Image 2 gives nice drama with the lighting and pops out. Image 4 is simply classic. Love the turf in the air - the perfect finishing touch!

I have to ask, what PP did you do to give them more drama? The scenes themselves look like war. They're great.

Absolutely fantastic images. It's hard to tell given these are web sized, and it could be just the light, but it looks like there is perhaps a touch too much edge sharpening (esp #1).

the main thing adding to the drama is the selective vignette, levels, curves, and some pro contrast tweaks...

Why so fast? You don't need that speed to freeze them and you could have lower ISOs.

They're good, looking into the sun like that is one of the hardest things I've found about sports photography. I too would be interested in your pp.

If you haven't already, try saving the image for a closer look. He has it sized perfectly for a 1600x1200 monitor.

Ya it might have been overkill, but handheld at that range, and with fast movement I was hoping for overkill to be honest (destructive testing I guess). I experiment more with shutter speeds next year...

800-5000, and maybe a few even higher...
