Yes I'm assuming it's setting at dusk. Point is this lens is long & heavy, just trying to find out how many arms he has. I’m picturing two to hold the lens, one to focus and another to operate the camera?

Forgot to compensate for the snowy background on the second one so I tried to improve it with the in camera filters...it sort of worked.

I took this one with my K-5:

All sizes | Common Ground Dove | Flickr - Photo Sharing!

These other two I took with my K-7 before I got the K-5:

All sizes | Anhinga with Branch | Flickr - Photo Sharing!

All sizes | Red-Shouldered Hawk w/ Prey | Flickr - Photo Sharing!

All were taken with my Sigma 500mm F/4.5

One of the next things I am going to do is get a 540 flash with a beamer. I heard it creates red eye in birds but there are post processsing programs than can take that out. I am not a fan of post processing although I do tweak my photos. If I have to take more than a few minutes to tweak a photograph then something was off in my technique.

Night ? This is just the sun going down 1/4000s as you can see in the exif data. Nothing to help me, I was just standing

Nice shooting, traderdrew--that hawk is particularly impressive! Which version of the Sigma are you using?

It is an immature Golden. The Bald Eagle has been hanging around a particularly slow part of a nearby river for the easy fishing. I was waiting for it to fly and the Golden burst out of a tree about 20 yards from where the Bald set up camp. It was a good day!!

The 500mm F/4.5 Sigma. It is 6.9 lbs and I handhold the thing. It is about as much as I would wish to carry around but I enjoy doing it. I think the hawk with the Sora Rail prey might have come out slightly sharper if I was using the K-5 and it would have caught the hawk a split second before during the turn.

I have read about the 150-500mm Sigma but I have had people tell me you really have to hold that thing steady beyond any focal length beyond 400mm.

It really is true that you have to catch the light well. Light is more important than your lens and camera. If you don't see any color on the bird, don't even bother trying to get it with your K-5 or any other camera.

ISO 3200 K-5 at 700mm

Just killing time shooting a couple of birds this morning. And thought I would see if the K-5 could take a good pic at 3200 ISO. Actually these are good enough for the internet only. But I was surprised at the performance of the K-5 again!

These two shots were both at 700mm wide open, 500 + 1.4 t.c. F6.3 ISO 3200
I denoised the background only. The birds are not denoised.
Next time i may try stopping down a stop and see if I can get more detail.
But the birds loose a lot of detail when uploading to this site.

Cool: Thai birds! But you're right--the noise is pretty bad.

K-5 @ 1200mm

Was practising with the F*250-600 at the weekend and tried out the cheapo 2x Tele Plus teleconverter on it.

This one is at 1200mm, manually focussed, f6.3, 640 ISO, 1/250s

Nice shot of the gull. I have a few shot's with the 500 and 2.0x sigma t.c. in very bright light it actually Auto focuses. And i am really surprised at the quality. Here is a link to one photo. It is a very long shot.

Caspian Tern | Flickr - Photo Sharing!

You know I haven't thought of trying it with the K-5. The photos I shot were with the K-x.

I have herd good things about the 250-600 lens. There is another guy here with one that really is good. But I have to admit. I do not even own a Pentax lens. other than 2 kit lenses. So i am not in any means an expert on Pentax lenses. If i am lucky one day Pentax will come back with some quality primes above 300mm at f4...... I hope...

What is the largest f stop for the 250-600 lens. You have it as f6.3 with a 2.0x is that double? F 12.6

Looks great. Only had the 250-600 for a few weeks, and since we've had it, we've had no sunshine. Really looking forward to good weather to really see it sing.
