Yep, a lot. It has rained heavily here this morning and is dark outside, so I tried to see how low I could go to keep the ISO down. About 1/80 handheld is about the limit for me. Some 1/40 didn't turn out too good. Generally that 1/200 @ 500mm will get you a decent shot if you snap two or three....one is usually usable...sometimes all three. You have to be very steady and brace the eyecup to your forehead.
1/80 ISO 2000 f6.3 @ 500mm through my office windows.
Looks like she took a drenching!

I'm thinking the K1 might offer a lot better noise reduction which would allow more speed at a higher ISO...if so...I want one!

Terry, I don't have a TC. In the past I have not been impressed using a TC on most anything. I see mixed results from others.....some very good. I suspect you are right that the longer you reach out the harder it is for SR to work its best?
500mm on the Bigma is not a problem for SR in my experience. Provided your handling of the lens is adequate. I've done a lot of with/without testing over time and the SR is absolutely effective compared to going without it. I don't use the OS on my newest Bigma 50-500, it slows shooting time a little and is no better than the Pentax SR in my evaluation.
How do you like your 150-450? I am leaning toward one myself, and possibly a K1 to go with it. I have some questions first and will wait until I see some results when the K1 gets out in the wild.
Best Regards!:)

Here is one at 1/60 @500 mm with the Bigma.....handheld. It suffers a little but is usable, after all...all squirrels are handsome!:D
In looking at my bird and squirrel shots, the most used speed is 1/200, which is usually a safe speed for SR if there is no movement in the subject.
I told him to freeze, but he is a young one and modeling is new to him...he'll learn in time! :lol:

After many thousands of shots with my Bigma lenses at or near 500mm and most of them at low or very low shutter speeds, I have long been a rabid fan of Pentax SR. It just works! :D
There is still a need to learn the handling techniques of a big heavy lens, and without that the results will deteriorate rapidly. You can't just go swinging the lens around while snapping and expect decent results...but if you master different holding techniques it can provide very usable results on a regular basis. I see a lot of people give up on long lens shooting because they fail to master the techniques required. Some may just lack the strength to handle a heavy lens, which I understand...they can get tiring pretty fast if you are not used to a heavy load in your hands.
Here I crossed my arms and used one arm to brace the other....a common technique that I often use. You can't hold that position long with all that heavy lens dangling out in space past your hand that is holding it and the lens, but a few seconds is usually long enough to get the shot.
Hand held 500mm 1/125 ISO 1000 f6.7 Not an uncommon result.

I shoot with a K5IIs and assume the SR on the K3 is as good or better? 99.5% of my shots are handheld with the Bigma 50-500, and the vast majority are at or near 500mm. SR is very effective, and I even prefer it over my Bigma's OS.
I have compared with or without many times and without the SR it is rare that I get a good clear sharp shot.

The K1 is said to have even better SR and that interests me greatly. Along with the other features it offers, it might be worth the investment even though I am only a purely amateur shooter.
